The filtering mode of the oil filter

Filtration process: the porous permeable medium is used to filter out the insoluble substance in the oil solution to separate solid particles > 1 m. The paper fiber can absorb a small amount of water.
Electrostatic process: the electrostatic field force is used to make the non-soluble pollutants in the oil adsorbed on the dust collector in the electrostatic field to separate solid particles, sludge and < 1 m "soft particles".
Magnetic process: Separation of ferromagnetic particles by magnetic field force to absorb the ferromagnetic particles in the oil character.
Centrifugal oil filter:
By means of mechanical energy, the oil can move in a circular motion, and the radial acceleration generated can be used to separate larger solid particles, free water and a small amount of emulsified water from insoluble substances with different oil density.
Coalescing oil filter:
A mixture of two insoluble liquids is used to separate free water and a small amount of emulsified water based on the difference in the wetting (or affinity) of the two liquids to a multi-pore medium.
Vacuum oil filter:
By using the difference of saturated vapor pressure under negative pressure, the moisture and air in various forms in oil can be separated from other liquids or gases.
Adsorption: Separation of solid particles, free water and emulsified water from soluble and insoluble substances in oil by molecular adhesion.

Heat resistant steel furnace

The degree of heat resistance and manufacturing technology of heat - resistant steel furnace

Heat resistant steel furnace is used in heat treatment furnace accessories, it is commonly used material is CrMnN, Ni7N, 2520 and other heat resistant steel, the degree of heat resistance of different materials are also different. For example, cr-Mn-N furnace tank is suitable for 850℃ ~ 900℃; ZG35Cr24Ni7N heat treatment equipment vacuum furnace suitable for 900℃ ~ 1050℃; ZG40Cr25Ni20Si2 furnace tank is suitable for 1050℃ ~ 1150℃.
High temperature strength refers to the ability of steel to withstand mechanical loads for a long time at high temperatures. Steel is softened under mechanical load at high temperature, that is, its strength decreases with increasing temperature. The second is creep, that is, under the action of constant stress, the plastic deformation increases slowly with the extension of time, and the plastic deformation of steel at high temperature is caused by intra - grain slip and grain boundary slip. Alloying is usually used to increase the high temperature strength of steel. It is also the addition of alloying elements to steel to enhance the bonding strength between atoms and to form favorable structures. By adding chromium, molybdenum, tungsten, vanadium, titanium, etc., the matrix of steel can be strengthened, the recrystallization temperature can be raised, and enhanced phase carbide or intermetallic compounds can be formed, such as Cr23C6, VC, TiC, etc. These hardened phases are stable at high temperatures, insoluble, do not aggregate and grow, and maintain their hardness. Nickel was added mainly to get austenite. Austenitic atoms are more closely arranged than ferrite atoms, and the bonding force between atoms is stronger. So austenite is stronger at high temperatures. It can be seen that the high-temperature strength of heat-resistant steel is not only related to the chemical composition, but also related to the structure.
Heat resisting steel furnace can be divided into cover furnace, nitriding furnace, carburizing furnace, star anise furnace, cylinder furnace, heat treatment furnace, CRMNN furnace, centrifugal furnace, etc. It can also produce non-standard furnace tank according to customers' requirements, which can withstand 1150 degree high temperature, and not easy to denatured, heat and corrosion resistant.
At present, there are two kinds of heat-resistant steel furnace tank, one is casting, one is welding, welding material, Swedish plate 310S as the best, the life can go to 2-5 years, and this material of heat-resistant steel furnace tank weight is lighter, heat faster, more energy saving, quality is the best.
Heat resistant steel furnace tank, of course, also can use the centrifugal casting process, apply for centrifugal casting process of the seamless pipe in tank top casting furnace, tube wall tissue density high, uniform wall thickness fluctuation, more solid and durable, not easy appear high temperature deformation, the service life of the warranty in more than one year, product advantages more apparent.
Among the many heat-resistant steel brands, the following factors must be considered comprehensively when choosing heat-resistant steel that meets the working conditions of the cement plant:
(1) The working temperature of heat-resistant steel castings. Operating temperature refers to the highest, normal and lowest temperatures and the rate of change of temperature.
(2) Mechanical load of heat-resistant steel castings.
(3) Gas in contact with heat-resistant steel castings and their conditions (including wind speed dust content, chemical composition, etc.).
(4) The price should be low, where can use chromium, nickel content low cast heat resistant steel, not high chromium, nickel content.
The experience of using heat-resistant steel castings should be constantly summarized and accumulated in cement plant. If there is failure problem in use and it is proved by analysis that the abnormal scrap of heat-resistant steel castings is caused by improper material selection, the manufacturer can contact with the manufacturer to prevent failure by studying the material selection. The manufacturer should provide the material selection data and indicate the direction to the using factory.
In a word, heat-resistant steel furnace and tank products have a series of advantages, such as high temperature resistance, high strength, not easy to deformation, good oxidation resistance, etc., so the furnace and tank are widely used in heat treatment, can also meet the special casting requirements of metallurgy, mining, petrochemical, shipping, building materials, electric power, light industry, machinery, military industry and other industries.
In fact, in addition to heat resistant steel pot, similar to the heat resistant steel workpiece there are many, are to meet the special requirements of the processing was introduced. Metal heat treatment equipment as a specific special properties of material, heat resistant steel has many USES, can play an important role in various industries.

What points should be paid attention to when welding heat-resistant steel

What points should be paid attention to when welding heat-resistant steel castings? Today, let heat resistant steel casting to give you a detailed talk about this problem!
Main point 1: The welding position of heat-resistant steel casting should choose welding, symmetry welding, then the overall welding method, in order to prevent the stress of the casting split, welding a layer (inner lapping), if the joint is small, can choose 3.2 welding wire. Welding wire 4.0 can be used for the second layer of electric welding. As the casting is very large, 1/6 turn can be used for piecewise welding.
Main point 2: For the crack of heat-resistant steel casting in electric welding, the weld should be cut along both sides of the crack first, and the deep and long of the weld should be removed and then welded again. Electric welding crack should be the first stainless steel head, from the crack root just started along the crack welding. For the strength of more than HRC38, cover to choose AI02 wire.
Point 3: For the layered welding part, the welding skin should be cleaned after the temperature of the first layer is cooled to 200-300℃, and then the second layer is welded, and so on.
Main point four: laser cutting and welding opening can be carried out with oxyacetyl block flame according to the working condition on the spot, so as to ensure the welding quality of electric welding. The surface layer of casting parts should be eliminated and cleaned to prevent defects such as oil stains and welding nodules.
Basic methods to solve the problem of heat-resistant steel casting:
Description of phenomena -- analysis of causes -- formulation of measures -- verification of effects -- further improvement
That is to engage in heat-resistant steel forging, it is necessary to put forward countermeasures from the root cause of air vent. Because you are in the scene, the idea that everybody gives is also about, cannot analyze the situation on the spot deeply for you, want to rely on oneself colleague to analyze well to be able to solve difficulty truly.
A few points for reference:
1. How dry is the core sand? Are there any organic impurities mixed in?
2. Does casting ladle overpack so that more air is brought in? Can I change the small bags for pouring?
3. How about the aeration of the casting mold and sand core?
4. Whether there are design defects in gating system design

How does the oxygen valve work and operate?

When talking about the oxygen valve, many people think of the oxygen meter, which is often used by the oxygen valve, also known as the oxygen reducing valve. Oxygen valve is often used in physical and chemical experiments, and often use oxygen, nitrogen, hydrogen, argon and other gases. All of these gases are stored in a high-pressure gas cylinder, which is, of course, a dedicated high-pressure gas cylinder. During use, the pressure of these gases is reduced to the required range through the pressure reducing valve, and then fine-tuned through other valves to feed these gases into the system in use.
How the oxygen valve works
The high pressure chamber of the oxygen valve is usually connected to the cylinder, and the low pressure chamber is the outlet of the gas, which is usually connected to the service system. The gas pressure stored in the cylinder is marked by a high pressure gauge. The outlet pressure of the low pressure gauge can be effectively controlled by an adjusting screw.
In general, oxygen valves have safety valves, safety valves are used to protect the pressure relief valve, and make the valve for safe use. At the same time, the relief valve is also a relief valve, a signal device in case of failure, if the relief valve failure, the relief valve will have a clear display.
Use method of oxygen valve
In the use of oxygen valve, must be used in accordance with the requirements, so in the process of operation, will not appear problems. And the oxygen valve should not be in contact with grease, or there will be a fire. When the valve stops working, to put the remaining gas clean, and then the adjustment screw in the state of relaxation, so as to effectively prevent long-term compression deformation phenomenon.
The above is about the oxygen valve related knowledge, consumers in the use, must understand these related knowledge clearly, so as to better use.

Experience of needle valve

Needle valve is a type of valve, because its round core is like the tip of a needle, so it is called needle valve. Its characteristic is to be able to adjust freely, generally all the valves are used to do blocking function, such as for water, oil, steam, etc. The use is very extensive, for example, in the welding work needs the needle valve to control the flame after heating, if the control is not good, it is easy to have problems such as welding is not firm, or desoldering.
Needle valve pressure is much greater than other valves, in addition, when choosing to use needle valve, we must consider several situations: the needle valve is installed in the use position, whether its pressure is appropriate, whether it can withstand high temperature when selecting materials, if it is used on the head of welding gun for welding, it must be resistant to high temperature.
In addition, its corrosion resistance should meet the standard. In the pipeline with gas, stainless steel, carbon steel and other extremely anti-corrosion materials should be adopted as far as possible to ensure safety. When the degree of corrosion is not too serious, when the temperature and pressure are not too large, the needle valve of non-metallic material can also be selected. For example, when the pipeline is filled with water, plastic materials can be used instead of stainless steel. Not only considering the hidden danger of appearance, but also protecting the outside. You can paint some pigment or paint as a new protective layer.
In determining the use of needle valve installation, to consider its appearance in your use is convenient, beautiful, the position is accurate, whether the installation is firm, these will affect the use of needle valve quality and effect, there is the most important installation to check whether it has sealing, such as improper sealing will also cause safety hazards and economic losses.

Pressure rating of wafer butterfly valve

Q: Hello valve, what is the pressure level of butterfly valve? What is the maximum pressure of butterfly valve?
Answer: clip butterfly valve can be divided into two types, clamp hard seal butterfly valve and clip soft seal butterfly valve.
The maximum pressure of the butterfly valve can be 16 kg, that is, 1.6 MPa, which can be used in water, gas, oil medium pipeline. If the pressure exceeds 16 kg, the soft seal seat material will be damaged due to excessive pressure, which will affect the sealing performance of the valve.
It is recommended that the maximum pressure applicable to the clamp hard seal butterfly valve should not exceed 4MPa. Although the structure of the hard seal can withstand high pressure, the pressure bearing capacity of the clamp type connection is not as good as that of the flange connection. If the pressure is too high, it may cause leakage at the joint between the butterfly valve and the flange.

What are the difficulties in the maintenance of industrial water purification equipment

Industrial water purification equipment is widely used in laboratories, hospitals and some large factories. In these areas, the water quality requirements are generally high, and the water needs to be treated by water purification equipment before it can be put into use. So what are the maintenance difficulties of this kind of industrial water purification equipment?
Membrane clogging. If the prefilter is not replaced or cleaned for a long time, the water quality inside the machine is far worse than that before entering the machine. The raw water quality is poor, but the proportion of wastewater is small, resulting in the blockage of waste water solenoid valve or flushing combination valve, and then no wastewater is produced, or there is very little waste water, which leads to the blockage of membrane and shorter service life.
The filter element is blocked. One of the common faults of the equipment is the blockage of the filter element. It is very important to replace the filter element for prolonging the service life of the equipment.
There is something wrong with the transformer. If there is a fault in the transformer, it can not provide the voltage required for the normal pressurization of the pump, so the speed will be slow, the increased pressure will be small, and the pressurization will be small.
Naturally, the pressure required for the tap water to pass through the RO membrane will not be reached. At this time, the water production will be slow. After eliminating the factors of pump and membrane, it is necessary to replace a new transformer.
Water tank material. Because of its high purity and almost no impurities, ultrapure water is easy to absorb pollutants from the external environment and cause pollution. If the water storage tank we use is low-grade plastic, it will be easier to dissolve some organic matters, thus increasing the conductivity of water, leading to the decline of water quality.

Two ways of heating a resistance wire

High temperature resistance wire factory introduces two ways of heating resistance wire:
1. Insert the heating element composed of resistance wire into the mold heating plate;
2. Place the resistance wire directly in the heating plate of the mold.
When designing mold resistance heating, the following basic requirements must be considered:
1. Protective measures of the heating mold should be considered to reduce heat conduction and heat radiation loss. Generally, asbestos insulation board is set between the mold and the upper and lower pressing plate of the injection machine, as well as around the mold. The thickness is about 4-6mm;
2. Different power heating elements are used in the central and edge parts of the heating plate respectively. Generally, the power of the heating elements in the central part of the mold is slightly lower, while the power of the heating elements in the edge part is slightly higher.
3. Two sets of temperature instruments should be installed on the electric heating plate of large molds to control and adjust the temperature of the central and edge of the electric heating plate respectively;
These are the two ways of heating a resistance wire.

Oil filter has made new achievements in decolorization technology

In the research and development of oil filter, the oil filter used to filter the mechanical impurities and moisture of oil products has become a widely known technology. However, the decolorization of oil filter to make it closer to or even fully match the quality of the new oil is still a topic that many researchers keep exploring.
After continuous theoretical exploration and experimental operation, the company finally developed a new type of oil filter, which not only has the traditional function of removing impurities, moisture and harmful gases, but also has high-performance decolorization function.
After practical application, this decolorizing oil filter has the most obvious filtering effect and higher filtering accuracy. In line with modern industrial equipment for high precision oil demand.
How does an oil filter achieve this filtering effect? The engineer made the following introduction:
A. Operating principle of the oil filter: vacuum decompression, film atomization, three-dimensional flash evaporation, dehydration and emulsification breaking and micro-filter purification technology; the whole machine has no filter element, no filter plate and pure physical decolorization and odor removal;
B. Oil filter's action object: anti-wear hydraulic oil (black, red, white, etc.), mechanical oil (12#, 16#, 32#), light oil (diesel, kerosene, etc.) and other lubricants;
C. Vacuum separation system of oil filter: vacuum separation technology from Italy has been introduced, which is composed of atomizer, reactor, separation chamber, accumulator oil tank, exhaust chamber, foam eliminator, observation window and liquid level device.
(1) atomizer: atomize the oil into the vacuum separation system and spray it onto the reactor;
(2) reactor: composed of multiple rashig rings, let the oil mist sprayed on the reactor to form an oil film, so that the water in the oil, gas as far as possible to volatilize, greatly improve the efficiency of dehydration and degassing;
The separation chamber: located between the reactor and the fuel tank, the oil is separated again from the water, gas and oil when the oil runs in this section;
And gather the tank; Will separate the water, gas oil accumulation, by the exhaust pump discharge;
Extraction chamber: the water vapor and residual gas separated from the reactor and separation chamber are extracted from the vacuum separation system. Avoid redissolving water and gas in oil;
• antifoaming device: the use of Japanese omron device; Automatic elimination of oil bubbles in the oil, replace manual defoaming, so as to achieve online operation unattended;
Observation window: use toughened glass as observation mirror, replace plexiglass as observation mirror when the defect of depression deformation under high temperature and high vacuum conditions;
Realization of automatic level control device: being configured in and out of the oil automatic balance adjustment, constant oil filtration system to achieve the purpose of man-machine separation, and set up a high level and low level protection system;
'levies adopt complex three-dimensional flash evaporation system, thereby increasing the evaporation area and prolong the cleansing oil in vacuum separation system of evaporation time, greatly improve the dehydration (free water, micro water) degassing efficiency;
D. special filtration system of oil filter:
Under the action of interfacial tension friction, the oil produces a certain amount of metal iron foam, which cannot be solved by filtering (too much iron foam leads to frequent blocking of magnetic filter element). This system can absorb various sizes of iron foam, the capacity of pollution is the general magnetic filter 30 ~ 50 times. Electrostatic degaussing can effectively filter the gum, asphaltene and carbon residue of aging oil products (a major obstacle that cannot be solved by ordinary oil filters), which greatly improves the cleanliness of oil products.
E. The oil filter is equipped with an automatic backwashing system:
With back flush fast, clean, completely, especially for some special oil cleaning complex, must remove to cleaning process, as well as the groove part of the equipment cleaning, from the design of the device itself and pipe connection, on the basis of fully out of the past artificial problem caused by a variety of cleaning, give full consideration to the customers in the use of equipment in the process of encounter various difficulties.
F. Pure physical decolorization system of oil filter:
It is equipped with rotatable uniform heat mixing system (the key technology of decolorization) to absorb and remove impurities such as melanin which cannot be filtered

Preparation of drying process

The drying process of periodic forced circulation wood drying chamber includes: preparation, control of drying standard, completion of drying and storage of dry wood.
The preparatory work before drying includes the inspection of drying equipment, the establishment or selection of drying standards, the determination of medium moisture content and drying quality indexes, the sawn inspection board and test board and the testing of its moisture content, the piling of wood or wood cart into the drying chamber, etc.
Inspection of equipment: in addition to regular inspection of the drying equipment, before each drying operation, the drying equipment must be checked again, such as changing the gauze cloth for the wet bulb thermometer, changing the balance moisture content test piece, lubricating oil injection, etc., to ensure that the drying equipment is in a trouble-free state.
Establish or select drying standards: select or establish drying standards according to the species, specifications, drying quality requirements and drying equipment performance of the dried wood.
Determine final moisture content and drying quality indexes: determine final moisture content and drying quality indexes according to customer or production requirements. Generally, the final moisture content of dried sawn timber is determined according to the equilibrium moisture content of the wood area. At the same time, the use of sawn timber should be referred to. In general, the final moisture content of dried sawn timber is 2%-3% lower than the equilibrium moisture content of sawn timber corresponding to the local average relative humidity, and the final moisture content of dried sawn timber can be lower if it is used indoors.
Sawn inspection board and test board, test its moisture content: each dry must have a test board, but can not have a test board.
The following precautions should be paid attention to when entering the drying room:
(1 )The same drying chamber by dry wood must be the same species or wood similar, the thickness is the same, the initial moisture content is basically the same.
(2) When loading materials should be careful, do not touch the door, wall and indoor equipment, piled up or stacked to be stable and tidy.
(3) the windward side must be filled with wood, leaving no gaps. That is to say, for the orbital drying chamber, the air flow passes through the pile laterally and must be filled along the direction of the length and height of the drying chamber. For a forklift loading and unloading drying chamber, the air flow through the stack longitudinally must be filled in the direction of the width of the drying chamber and (or the length of the stack) and the height. If the material pile is not enough to fill a room, you can reduce the width of the total material pile (or reduce the number of columns), but the total length and height of the material pile, or the number of nodes and stack of each column of material pile can not be reduced, so as to avoid leaving a gap, short-circuit air flow, resulting in uneven drying, and has produced a drying defect.
(4) the same column heap of the material heap as close as possible, without leaving a gap, adjacent to the column pile, the position slightly staggered before and after, so as to avoid the pile end to end connected or the end of the gap is difficult to avoid through each other.
(5) Pay attention to the pressurized weight on the top of the pile.
(6) Put the moisture content of the test board and stress test board. If electrical moisture content measurement method is adopted, moisture content measurement points should be no less than three, and evenly arranged in different positions in the material pile, and finally the connecting wire is inserted into the corresponding socket installed on the chamber wall. If using the test board weighing method, should measure the moisture content of the test board initial moisture content, initial weight, and calculate the total dry weight of the test board, the test board end coated with waterproof paint, by the test window or inspection door into the material pile, and to prevent condensation water drops.

How to measure furnace temperature in high temperature electric furnace

High temperature electric furnace is used for the heating of precision experiments, the furnace temperature is the key factor to ensure the success of the experiment, the quality of the heating workpiece also depends on the high temperature furnace furnace temperature control, it can be said that the timely grasp of the furnace temperature condition is the high temperature furnace work quality and efficiency guarantee. Therefore, the importance of high temperature furnace temperature measurement work is self-evident.
High temperature electric furnace is according to the temperature ring in the absorption of heat will shrink to complete the temperature measurement work, according to the temperature ring and the cumulative heat burning products, the conversion of the test temperature. The temperature setting ring can be placed in any position in the high temperature electric furnace, such as kiln furniture, kiln car or carrier plate, or together with the heating workpiece. The shrinkage rate of the diameter of the calibration ring accurately reflects the actual temperature of the calibration ring in a high temperature electric furnace. It is easy to measure the diameter of the temperature - setting ring after firing by the common 1000 - minute calipers. For accuracy and convenience, a special conversion table is attached to each batch of calibration rings. Please note that the batch number on the calibration ring must be the same as that on the temperature conversion table for proper use.
There are many advantages in measuring furnace temperature with calibration ring for high temperature electric furnace. The calibration ring is flexible and easy to measure any corner of three-dimensional space in the furnace. The setting temperature ring is placed in the position closest to the actual heating condition of the product, and the heating condition of the burned product is accurately determined. The use of a temperature-setting ring can reduce or even eliminate the need for measurement or destructive testing of the geometry, density and porosity of the finished product, thereby reducing the cost of quality control in the production process; The temperature-setting ring has a good consistency, which can guarantee the good reproducibility of the firing system of the products, so as to improve the qualified rate of the finished products of the high-temperature electric furnace heat treatment.
It is a complicated process to measure the temperature of high temperature electric furnace. What the temperature measuring ring measures is the heat accumulated in the whole firing process, including radiant heat, conduction heat and convection heat, as well as the comprehensive effect of different holding time. It can not only measure the highest temperature reached by the burning products, but also reflect the heating state of the products in the process of heating the products by the high temperature electric furnace. Therefore, it can be said that in the high temperature electric furnace temperature measurement work, the role of the temperature adjustment ring.

Forging equipment industry also needs innovation

Does the machine tool industry need jobs' creative vision, too? Is this design concept needed in the machine tool industry?
The word "design", in the machine tool industry seems to be still very unpopular, is not a word that makes people sound excited. Due to the characteristics of the industry, machine tool products in the construction environment, the first emphasis is on safety and practical, it seems that there is no need to rack their brains to rely on bright appearance to impress customers; Machine tools are far from the general public and do not need to dazzle consumers with fancy models; At the same time, China's machine tool industry started late, and the current industry competition is still in the extensive stage for a variety of reasons, making the machine tool industry and even the heavy industry design culture is extremely lacking, and the highly sought after product designers in the industry are rare.
In the product innovation chain, r&d and design are driven by each other, both of which belong to "brain engineering". A high quality machine tool products, safety and utility is only the minimum conditions, machine tool design field is not limited to the simple model idea, but a product category, ergonomics, brand recognition and other systems of science. Like corporate culture, the design culture of machine tools also needs to be nurtured and nurtured slowly.
What role does the design of the machine tool play in the production process? Is the principle of "external function" still valid, or should the external design be the first and the function the second? To these questions, the industrial graduate designer and CEO of the German company replied, "I have never been a big fan of the idea of 'function of form,' because at the moment it's a cliche. For example, a wheel should of course be round, or it wouldn't roll. But that doesn't mean that a wheel in a particular position necessarily represents a sensitive solution."
Whether it is the imagination ahead of the imagination, or full of creative ideas, for the machine tool industry to bring a new air. We look forward to the emergence of many design masters like Steve jobs in the machine tool industry to enliven and energize the machine tool industry.

Nitrogen making machine is designed and manufactured according to pressure swing adsorption technology of nitrogen making equipment. The nitrogen-making machine takes high quality imported carbon molecular sieve (CMS) as adsorbent and USES PSA to separate the air at room temperature to produce high purity nitrogen. The equipment is compact in structure and can be mounted on the whole. It occupies a small area without capital construction investment and requires a small investment. Nitrogen can be produced only by connecting the power supply on site.
What are the operation precautions of the nitrogen machine? Let's take a look:
1. Adjust the nitrogen production valve after the flowmeter according to the gas pressure and the amount of gas used. Do not arbitrarily increase the flow to ensure the normal operation of the equipment;
2. The opening degree of nitrogen gas production valve should not be too large to ensure the best purity;
3. The debugging personnel should not adjust the valve at will, so as not to affect the purity;
4. Do not arbitrarily move the electrical parts in the control cabinet, and do not arbitrarily dismantle the pneumatic pipeline valve;
5. The operator should regularly check the pressure gauge on the nitrogen machine and make a daily record of its pressure change in case of equipment failure analysis;
6. Regularly observe the outlet pressure, flow meter indication and nitrogen purity, and compare with the required value to find problems and solve them in time;
7. According to the technical requirements of air compressor, cold dryer, filter maintenance and maintenance, to ensure the air quality (air source must be oil-free). Air compressor, cold dryer must be repaired at least once a year, according to equipment maintenance, maintenance provisions to replace wearing parts, and maintenance.
8. Air separation nitrogen production equipment in the process of work, carbon molecular sieve has some wear, should be checked and filled with molecular sieve once a year.

Fully automatic water softener structure

Water softening equipment is to use the resin to soften the source water, the main purpose is to let the resin adsorption of calcium, magnesium ions in the water (the main component of scale formation), reduce the hardness of the source water, and can carry out intelligent resin regeneration, recycling.
Automatic water softener (water softener) structure
1, control valve: the use of domestic or imported automatic brand control valve, complete functions, stable performance.
2. Anti-corrosion tank body: the tank body is made of glass fiber reinforced plastic (carbon steel or stainless steel lined tank body can be selected). The tank body is anticorrosive, pressure-resistant and has a long service life.
3, uniform water distribution system: the use of jet water distribution, the effective exchange capacity of resin can be fully played, with salt control precision, no need for salt pump.
4, high-performance resin: domestic, imported high-quality cation exchange resin, low damage rate, uniform particle size, improve ion exchange rate.
Automatic water softener (water softener) features
1. High efficiency: the overall design of water softening device is reasonable, so that the effective working exchange capacity of resin can be brought into full play.
2, provincial work: high degree of automation, no need to set a person on guard.
3. Water saving: the water production rate of the softening water device is more than 98%.
4, power saving: siphon regeneration principle, no need for salt pump, power consumption is only equivalent to manual soft water equipment 1%.
5, small space: only need to provide resin tank and salt tank space, save the space occupied by the pipeline, salt pump.
6. Easy adjustment: users can adjust the regeneration cycle and regeneration time according to their actual needs.
7. Low operating cost: due to the high degree of automation, the water softener can adapt to the water volume changes, accurately measure the water yield and the amount of regenerant, avoiding the innocent waste of regenerant in the process of regeneration, and saving a large amount of labor cost at the same time.
Automatic water softener (water softener) working procedure
1. Water supply: the untreated water passes through the resin layer and produces soft water through exchange reaction.
2, back wash: water from the lower layer of resin into the resin, loose the resin, remove small debris.
3, salt absorption slow washing: the use of high concentration of salt water (Nacl) through the resin, the failure of the resin to re-reduce to sodium resin.
4, forward washing: according to the process of water supply, the water through the resin to wash off the excess salt solution and regenerate the exchange of calcium and magnesium ions.
5. Water injection: water is injected into the salt box to dissolve salt for the next regeneration.
