Oil filter needs to enter the era of independent research and development

At present, the oil filter machine industry has been in the traditional mode to develop, but now with the change of the social development, is the modern science and technology innovation, to meet customer demand, the main research and development since the business instead of blindly introduction and imitation of traditional mode, to make the filter oil machine industry and market of our country healthy development, and catch up with the world's advanced level as soon as possible.

Attach importance to independent RESEARCH and development

From the perspective of the existing technology level, China's oil filter industry started relatively late, without good processing technology and supporting industry support, so it has been following the way of copying foreign advanced equipment, lack of independent innovation, many domestic enterprises production equipment or use foreign relatively backward technology. In the same conditions of use, although they can meet the normal production needs, but in the precision, quality and stability of the equipment with foreign equipment or there is a significant gap.

At the same time, due to the lack of adequate attention and investment in research and development and innovation, domestic enterprises are still unable to produce oil filter equipment with a higher degree of automation, and cannot catch up with the innovation progress of foreign manufacturers. Of course, China's oil filter industry also has many advantages:

1. The design idea is flexible and not rigid as in foreign countries. It can be designed closely according to the special needs of different users;

2. Having a close space distance with domestic customers, I can use a variety of channels to understand the problems of equipment in actual production, solve them timely, and apply this experience to the research, development and manufacturing of new equipment;

3. The manufacturing and commissioning cycle of the equipment is shorter than that of foreign countries, and it is characterized by low cost and sufficient maintenance resources.

According to the above advantages, China's oil filter industry should make full use of advantages and avoid disadvantages, on the basis of not abandoning the introduction and absorption, fully attach importance to equipment research and development and innovation investment, with more perfect product series, more intimate design, more adequate supporting and more refined manufacturing, to impress domestic and international customers.

Manufacturing must keep improving

From the perspective of equipment manufacturing, the processing and manufacturing precision of China's oil filter is not high, and its appearance design is not beautiful enough. This is manifested in two aspects: on the one hand, the processing precision of the equipment is not enough; on the other hand, the processing technology and level are uneven.

Humanized design

From the perspective of the use of equipment analysis, domestic oil filter equipment in the humanized design, automatic control easy to operate degree are still some deficiencies, which reflects the domestic oil filter industry to the user feedback collection and equipment adjustment degree is not in place.

China's oil filter industry only fully consider the user's feelings, carefully designed more humane, more in line with the user needs of the equipment to occupy the domestic and foreign user market, improve the level and status of the industry.

China's oil filter industry has a broad space for learning, in the current industry is facing a new round of structural adjustment, technology upgrading, the important moment of product upgrade, domestic enterprises need through independent innovation, in-depth digestion, with a pragmatic attitude to develop enterprises and enhance competitiveness, in order to become a giant oil filter industry.

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.

The filter facilitates recycling of waste oil

The engine oil cannot be used after a period of time, and it needs to be replaced. The performance of engine oil changes because the oil enters impurities, and the oil itself produces harmful substances. However, whether the oil needs to be replaced should be considered from the following aspects:
Viscosity: too high oil viscosity, low temperature start and pump performance changes, cooling effect decline, on the engine friction and wear have adverse effects. Too low viscosity, oil lubrication, will increase wear. Therefore, most viscosity indicators are 100 degree scrap.
Moisture: Due to the wide range of engine temperatures, a small amount of cooling water is inevitably injected into the oil. Therefore, the maximum moisture content of engine oil has been set at 0.5%. The excess is probably free water.
Impurities: Oil contamination can be generally determined from n-pentane and insoluble solids.
Acid value: Engine bearings are most susceptible to acid corrosion, and new oleic acid values sometimes exceed 0.5 law. Therefore, the acid value of the oil is determined to be the maximum according to the changes of additives and acid value in the oil.
Flash point: Flash point is also an indicator to determine whether the oil is scrapped.
After the lubricating oil is polluted, a vacuum oil filter is used to filter the oil to restore the original index. Vacuum oil filter is a professional for dewatering waste oil, removing impurities, water-soluble acid, etc., so that the degraded oil after treatment to improve the pressure value.
