With the rapid development of hydraulic industry technology, hydraulic technology continues to trend toward high pressure, high precision and high power, and at the same time puts forward higher requirements for the reliability of the hydraulic system. And 70% of the failures in the hydraulic system are caused by oil pollution, and 60% of the pollution comes from new oil. The pollution of the system components during the working process accounts for 20%, and other reasons account for 20%. The particles in the pollutants that are generally 5-15 microns are extremely harmful to the precision parts of the system.
For this reason, internationally, strict control is adopted on the cleanliness of oil with precision components in hydraulic systems, and the cleanliness of new oil added is required to reach level 7 of GJB420 to ensure stable and reliable operation of the system. However, sampling and analysis from domestic hydraulic oil drums shows that the cleanliness of domestic new oil is generally only level 10 to 11 of GJB420. If the new oil with such serious pollution is used without strict filtration and purification, it will bring serious harm to the life and reliability of the precision components of the entire system.
In summary, in order to adapt to the development of hydraulic technology, our company has developed a multi-functional, high-viscosity oil filter based on the full use of the production of various high-precision filter technologies. Portable high-precision oil filter is suitable for the use requirements of all modern domestic and foreign advanced hydraulic equipment. It is the current domestic advanced oil filter device.
