Every hydraulic system must consider the purity of the hydraulic oil, which is the original purpose of using the Hydraulic Filter, so the filtration accuracy is the first consideration.
Some people will say: In this case, I would not choose the hydraulic oil filter with the highest precision.
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, 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.
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 corrosive. The specific use of ordinary filter or anti-corrosion filter should be determined according to the actual situation.
The above is the relevant content of the hydraulic oil filter, I hope to help everyone.
