The hydraulic oil filter is mainly made of paper filter, chemical fiber filter (glass fiber metal fiber sintered felt polypropylene fiber polyester fiber) mesh filter (stainless steel mesh) wire gap filter.
The hydraulic oil filter is suitable for filtering strong acid, strong alkali and organic solvent. The filter membrane is folded deep filtration. The membrane filtration area is large, the pressure difference is low, the dirt holding capacity is strong, and the service life is long. There are various models and specifications to choose from.
When selecting a hydraulic oil filter, the following points should be noted:
Hydraulic oil filter filtration accuracy
Every hydraulic system must consider the purity of the hydraulic oil, which is the original purpose of using the hydraulic oil filter, so the filtration accuracy is the first consideration.
Some people will say: In this case, I would not choose the highest precision hydraulic oil filter (so that it is filtered)?
The high-precision filtering effect is indeed good, but this is actually a big misunderstanding. The accuracy of the hydraulic oil filter required for the hydraulic system is not “high” but “appropriate”. High-precision hydraulic oil filter has relatively poor oil-passing capacity (and the accuracy of hydraulic oil filter installed at different positions is not the same), high-precision hydraulic oil filter is also more likely to block, if it must be used, it will affect the oil flow rate. One is a short life and must be replaced frequently.
Hydraulic oil filter strength
Secondly, it is strength and corrosion resistance. The strength of a good hydraulic oil filter must meet the standard. The hydraulic oil filter of the pipeline must be able to withstand the high pressure downstream of the pump. The filter of the suction filter should be able to withstand the condition that the oil flow is not affected. The pressure is not deformed and the mesh does not change the diameter resulting in a change in accuracy.
At the same time, the oil used in some systems has certain corrosiveness. The specific use of ordinary filter or anti-corrosion filter should be determined according to the actual situation.
Hydraulic oil filter installation precautions
The installation location should be considered. This is also an important part. If you are not sure where to install it, you will not be able to select a hydraulic oil filter. The function and accuracy of the hydraulic oil filter in different positions will be different.
How to choose a hydraulic oil filter? In fact, the choice of hydraulic oil filter mainly depends on three points: First, the accuracy, each hydraulic system must consider the purity of the hydraulic oil, which is the original purpose of using the oil filter. Followed by strength and corrosion resistance; finally, filter elements with different filtering functions and precision are selected according to different positions of the installation.
I believe that after knowing this, I believe that it will be of great help to you to purchase and use the filter.
