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.

What are the gasification reactions of experimental furnace fuel

The fixed experimental furnace at atmospheric pressure generally uses lump anthracite or bituminous coal and coke as raw materials, and uses steam or the mixture of steam and air as gasification agent to produce gasified gas with carbon monoxide and hydrogen as the main combustible components.
The gasification reaction of solid fuel in the experimental electric furnace is divided into five layers according to the characteristics of the production process in the furnace. The drying layer - at the top of the fuel layer, the fuel contacts with cold coal, and the moisture in the fuel can be evaporated; Carbonization layer - under the drying layer, due to the similar temperature conditions with the retort, the fuel undergoes cold decomposition, releasing volatile and other carbonization products into coke, and the coke is transferred from the carbonization layer to the gasification layer for cold chemical reaction; Gasification layer is the main area of gasification process in the furnace. Carbon and gasification agent in the fuel react violently in this area. In view of different reaction conditions, the gasification layer can also be divided into oxidation layer and reduction layer. In order to produce gas in a fixed experimental furnace, firstly, the air passes through the fuel layer, and the carbon and oxygen are cooled to increase the temperature. Then, the steam and air are mixed through the fuel layer, and the carbon reacts with the steam and oxygen to generate the gas by absorption and cooling.
From the principle of chemical reaction in the gas making stage of the experimental electric furnace, it is hoped to form conditions conducive to steam decomposition and carbon dioxide reduction reaction. Therefore, it can be considered that it is advantageous to increase the thickness and temperature of the gasification layer, and to appropriately reduce the flow rate of steam. In the chemical reaction of carbon and steam, measures such as increasing the thickness of gasification layer and reducing the air flow speed can accelerate the reaction speed, increase the content of carbon monoxide and improve the steam decomposition rate.

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.

Judge the color of transformer insulation oil filtered by oil filter

The determination of the color change after the filter of transformer insulation oil filter is mainly based on the naked eye observation to determine the depth of oil color. The color of the oil depends on the content of pitch, resin and other dye compounds. For example, in the original distillate, the asphalt, the less resin, the higher the light fraction, generally speaking, the lighter the color of the oil, the more transparent. The color of the oil is also related to the temperature and degree of refinement of the cut fraction. For example, the domestic no. 45 transformer oil has a lighter color and almost colorless appearance due to its lower cutting temperature and the process of adding antioxidants after overrefining. In the storage and operation of oil, under the influence of environmental pollution and the resinous substance generated by its own oxidation, its color will gradually become darker. Therefore, the environment in which the oil comes into contact, such as temperature, light, air (mainly oxygen), electric field, electric current, etc., can cause the oil to age and make the oil darker.
Application field of transformer insulation oil: liquid insulation medium such as insulation oil needs to test medium loss Angle and volume resistivity. For example, MS101Y insulation oil medium loss tester is used.
1. The arc. The electric arc in the middle of the contact when pulling the brake is quickly extinguished.
2. Insulation. Insulate the switch poles from each other and insulate the conductive part of the switch from the fuel tank.
3. Anti-corrosion. Prevent switch contacts from contacting air and avoid contact oxidation.
4. Heat dissipation. The oil is absorbed by the heat from the contact part and dissipated rapidly by the convection of the oil in the tank. Less oil circuit breaker because the amount of oil is very small, oil only plays the role of arc extinguishing, its shell is generally charged, must not touch.

Application of filters in printing

With the popularization of IT and digitalization, the necessity of color management has increased. Even if has considered the color reproduction and the dot generation and adds the net to make the various color printing plate, the printing dot expansion and the stable reproduction, is also the quality management premise.
Dot expansion is affected by printing conditions, printing materials and other reasons. Therefore, error management has become an important element, which must be standardized and applied. Comparing the absolute amount of dot expansion, the size of the error becomes a problem. The standardization of printing conditions has carried out a variety of types of curves, holding the different color version of dot expansion curve is the starting point of management. The main reasons for the error are as follows:
(1) lining is the basic reason, which requires the implementation of standardization including blanket quality.
(2) printing machinery, seven water ferrous sulfate to maintain ink characteristics of the temperature control is very important. The temperature control method of ink roller and ink bucket roller has been widely used. Ensure the stability of ink transfer by maintaining the set temperature. The matching compactness of the roller is also very important in this respect, have adopted matching compactness tracking structure (to maintain a certain pressure) to frame the roller.
In addition, because the fountain solution is used, it is equipped with auxiliary devices (pH, conductivity, temperature control device and automatic defiler of the fountain solution -- filter) to maintain the characteristics of liquid H. To maintain the stability of ink transfer, is a very important factor.
(3) the properties of fountain solution and ink balance, hebei plate and frame filter press is the most important factor in high quality printing. In the mechanical aspect, it is developed to reciprocating feed water → dageren method (the first inking roller and water roller are both used) → inking roller and water roller are independent. This is with the help of the fountain liquid film formation, help to maintain dot expansion, dot reproducibility, ink supply in the best printing characteristics of the structure.
(4) although it is not due to mechanical reasons, in order to keep the printing quality stable at a high grade, the printing process design is very important after the density benchmark is determined. The printing density will certainly affect the color reproduction. Aiming at the minimum error, the constant temperature of the machine and the standardization of printing conditions become the key points.

How should CNC machine tool production technology develop?

Any processing equipment, set during the processing, such as processing route, process preparation, processing cutting tool selection, the machine itself, the clamping and workpiece material, etc. Have a problem, for the final machining precision and machining efficiency can cause certain effect, vertical machining center as a highly precise and efficient processing equipment, reduce the workpiece machining error of the method commonly used to reduce the original error method, error compensation method, the error transfer method, grouping method, the error averaging method and synthetic method, etc.
1, error synthesis method to eliminate the machine error is to ensure the final machining accuracy of the workpiece is the most important method. Error synthesis method requires the measurement of the machine tool each axis of the original error. Laser interferometer is the main testing instrument in vertical machining center because of its high measuring accuracy and flexibility.
2, error compensation method error compensation method is to artificially create a kind of error, to offset the process system inherent original error, or use a kind of original error to offset another kind of original error, so as to improve the vertical machining center workpiece processing accuracy. Usually by reducing the machine tool clearance, improve the rigidity of the machine tool, the use of preloading load, so that the relevant cooperation to produce a pre-tightening force, and eliminate the impact of clearance. It can also improve the stiffness of the workpiece and cutting tool and reduce the length of the overhanging tool and workpiece, so as to improve the stiffness of the process system. Reasonable clamping and machining methods can also be used to reduce the cutting force and its changes, reasonably select tool materials, increase the front Angle and main deviation Angle, as well as reasonable heat treatment of workpiece materials to improve the machining performance of materials and other methods.
3, direct reduction of the original error method direct reduction of the original error method is to find out the main original error factors affecting the machining accuracy, to try to directly eliminate or reduce it. For example, vertical machining center in a long time after use, due to natural wear caused by the transmission system positioning misalignment, reverse clearance.
4, error average method error average method is the use of close contact between the surface of the comparison and mutual correction, or the use of each other for processing, in order to achieve the vertical machining center to eliminate the processing error.
5. Error transfer method the essence of error transfer method is the comprehensive error caused by the aggregate error, stress deformation and thermal deformation of the transfer process system. If the vertical machining center for some hole processing, the coaxiality of the workpiece is not by the machine tool spindle rotation accuracy to ensure, but by the fixture to ensure, when the machine tool spindle and workpiece using floating connection, the original error of the machine tool spindle will no longer affect the machining accuracy, and transferred to the fixture to ensure the machining accuracy.
6, error grouping method in the vertical machining center processing, due to the existence of process blank error, resulting in the process error. The variation of blank error has two main influences on this process: reaction error and positioning error.
If the above error is too big, can not guarantee the machining accuracy, and to improve the blank precision or the machining accuracy of the last procedure is not very realistic. At this time can use the error grouping method, that is, the blank or the size of the working procedure according to the size of the error into n groups, each group of blank error reduced to the original 1/n, and then according to each group to adjust the relative position of the cutter and the workpiece or adjust positioning components, so as to greatly reduce the size of the whole batch of workpiece dispersion range. The essence of error grouping method is to improve the measurement accuracy to make up for the deficiency of machining accuracy, so as to eliminate the influence of machining error.

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.

Use and maintenance of softening tank
It is the key sealing equipment in softening water preparation process. It is made of stainless steel, fiberglass material, and contains a certain number of cation exchange resin, their main role is when the original water flow through the resin layer, the cation resin in the water displacement reaction, in order to reduce the calcium and magnesium ions in the water, can provide customers with standard industrial softening water.
When the exchange capacity of the resin is saturated with calcium and magnesium ions in the water after the automatic water softening equipment works for a period of time, the exchange capacity of the resin is restored by the regeneration treatment of the ion exchange resin with brine by the salt tank.
Choice of resin
The general principle of resin choice is to choose the resin with large exchange capacity, must choose the resin with high mechanical strength, uniform particles, good heat resistance, when choosing the resin used in the Yang bed, choose the wet true density difference is large, but must be the resin of strong acid type.
Pretreatment of new resin new resin contains excess raw materials and new impurities, when the resin and water, acid, alkali or other solutions contact, these impurities will enter the solution, which will contaminate the water quality and affect the performance and service life of the resin, so the new resin must be pretreatment before use.
The selection and pretreatment methods of new resins are determined according to different objects.
How to keep the ion exchange resin
1. Anti-freezing: the resin should be stored in the surrounding environment of > at 40℃. If the temperature is lower than 5℃, the resin can be placed in an aqueous solution of salt to prevent the resin from freezing.
2. Dryness prevention: due to the disappearance of water content in the use or storage of the resin, the volume of the resin swells and shrinks, resulting in resin breakage or mechanical strength reduction, loss or reduction of ion exchange capacity. When this happens, do not throw the resin directly into the water, but first soak it in saturated salt water, so that it slowly expand without breaking.
3. Anti-mold: ion exchange resin placed in the exchanger for a long time is not used, will cause lichen growth and reproduction ****** *, leading to mold pollution of the resin, must be regularly changed and backwash. It can also be soaked in 1.5% formaldehyde.
