What is the difference between hydraulic oil return filter and oil suction filter?

01
Hydraulic return filter element
As the name suggests, the Oil Return Filter is the filter used in the hydraulic system oil return, installed in the hydraulic oil return pipeline, after the execution of the components, due to the wear and tear of the equipment may produce particle impurities and rubber impurities, etc., in the oil return system filter to ensure the cleanliness of the oil.
 
 
The characteristics of the hydraulic Return Oil Filter are as follows:
 
1, higher filtration accuracy, in 10-30um
 
2, installed in the oil pump outlet
 
3, belongs to the fine filter element
 
4, used for hydraulic system return oil filtration, filter the hydraulic system due to component wear metal particles, seals produced pollutants, so that the flow back to the oil tank to keep clean.
 
02
Hydraulic suction filter element
The Oil Suction Filter is also called the oil suction filter screen, which is installed in the oil tank below the oil, and is used to filter the solid particles and colloidal substances in the working medium. Filter filter material is made of copper or stainless steel woven mesh folded, this kind of filter has the characteristics of high temperature resistance, corrosion resistance, etc., can be repeatedly cleaned and used.
 
 
The characteristics of the oil suction filter are as follows:
 
1, high filtration efficiency, filter large particles of solid, can maintain the clean oil
 
2, small loss of original pressure.
 
3, using metal mesh filter material, long service life
 
4, simple structure, large oil capacity and small resistance
 
5, belongs to the coarse filter element
 
6, installed in the oil pump suction port, to protect the oil pump and other hydraulic components to avoid inhaling pollution impurities, can effectively control the cleanliness of the hydraulic system.
 
Oil suction filter and return filter are an indispensable part of the hydraulic system, the unique design and their respective performance for the hydraulic system of the liquid filtration has made a great contribution, applied to various industries of mechanical hydraulic system, can effectively protect the hydraulic system components, reduce maintenance, increase the efficiency of the equipment.
