The function of the hydraulic oil is the medium for converting the power, so it is strictly prohibited to mix foreign matter such as dust. The hydraulic oil filter prevents impurities from entering all parts of the hydraulic unit. The suction filter is installed in the hydraulic tank to protect the hydraulic pump in the hydraulic circuit. The oil after work will be returned to the hydraulic tank, and the return filter will be installed at the return position. Therefore, it is possible to judge whether the pump or other components of the hydraulic system are abnormal by observing the degree of contamination of the return filter.

 

 

The return filter is typically a low pressure device that only controls the contaminants generated by the system. When the oil passes through the above filter element, the impurities therein can be removed, so that the contamination of the filter becomes more and more serious with the accumulation of time. If the contaminated filter is not replaced in time, the flow of oil will be reduced and the original performance of the machine will not be fully utilized. In addition, if you continue to use a damaged or excessively contaminated filter, you will not be able to filter impurities, which will shorten the life of the machine. Therefore, the filter element should be replaced regularly, and if an abnormality is found during the maintenance and inspection on weekdays, it should be replaced immediately.
