The function of oil filter element is to filter the sludge in the engine and the impurities produced by the engine oil itself deterioration, prevent the oil deterioration, and greatly reduce the wear of various components in the operation process. In the practical application design of crushing hammer, we suggest adding an oil return filter element to prevent the impurities that have not been filtered out from entering the hydraulic system and damaging the hydraulic pump. So what is the function of installing the oil return filter element with the breaking hammer?

As for the hydraulic system as the main power structure of the breaking hammer, the hydraulic system is all over the whole excavator. It includes the hydraulic tank, main pump, control valve, each pipeline and the oil cylinder, motor and other parts that perform the action. These hydraulic parts are made by precision machining, and they have higher requirements for the maintenance of the hydraulic system.

When the hydraulic oil enters the hydraulic system, cleaning is the primary problem. The filtering effect of inferior hydraulic oil filter element is poor, which can not effectively prevent dirt and other impurities from entering the system. If tiny particles enter the hydraulic system, they will scratch the pump, block the valve and block the oil port, thus causing machine failure.

The hydraulic oil filter element is used in the hydraulic system to filter the solid particles and colloidal substances in the working medium, which can effectively control the pollution degree of the working medium, protect the safe operation of the machine, and extend the service life of the machine. Therefore, the advantages and disadvantages of the hydraulic oil filter element are very important.

Adding a return oil filter element on the basis of the original hydraulic filter device, the setting of the return oil filter element should consider more factors, one of the important factors is the hydraulic shock, especially when there is a hydraulic cylinder and a proportional valve in the upstream, under high pressure, the reversing of the hydraulic cylinder and the sudden power failure of the proportional valve will produce a great instantaneous flow shock, It will cause great damage to the filter element of the oil filter. When designing and selecting the oil filter of the oil return pipeline, we should have a full understanding and strengthen the structure.
