Importance of hydraulic oil filtration


For a long time, the importance of hydraulic oil filtration has not been paid attention to. People think that if there is no problem with the hydraulic equipment, there is no need to check the hydraulic oil. However, in practice, the cleanliness of the hydraulic oil indirectly affects the normal things of the hydraulic equipment. Relevant studies have confirmed that 80% ~ 90% of the press failure is caused by the purification of the hydraulic system. Mainly reflected in the following aspects:

1) When the hydraulic oil is oxidized, tense and dirty, it will affect the action of the hydraulic valve, showing signs such as stuck valve and rapid wear of valve core;
2) When the hydraulic oil is oxidized, emulsified and purified by particles, the oil pump will show cause faults due to cavitation, corrosion of the copper parts of the oil pump and the unsmooth moving parts of the oil pump, and even burn the pump;
3) When the hydraulic oil is dirty, the service life of seals and guides will be greatly reduced.
