When choosing an oil filter, consider the following:
(1) The filtering accuracy should meet the predetermined requirements.
(2) It can maintain sufficient flow capacity for a long time.
(3) The filter element has sufficient strength and is not damaged by the action of hydraulic pressure.
(4) The filter element has good corrosion resistance and can work continuously at the specified temperature.
(5) The filter element is easy to clean or replace.
Therefore, the oil filter should be selected according to the technical requirements of the hydraulic system, according to the filtration accuracy, flow capacity, working pressure, oil viscosity, working temperature and other conditions.
