Considerations for filters

Installation installation location of oil filter in hydraulic system usually include the following:

⑴ keep it in the suction port of the pump:

Surface of the pump suction line is installed on type oil filter, designed to filter larger particles of impurities to protect the hydraulic pump, and oil filter the filter capacity for the pump flow rate more than twice times, the pressure loss is less than 0.02MPa.

B installation on the export of oil at the pump:

Here to install oil filter is designed to filter out pollutants that may invade the valves and other components. 10~15 μ m to its filtering accuracy, and can withstand working pressure and impact on the oil pressure, the pressure drop should be less than 0.35MPa. While installing

Safety valve in case of oil filter clogging.

C installed on the system's back on the circuit: this indirect effect. General filters and the installation of a back-pressure valve, when the filter clogging pressure reaches a certain value, the back pressure valve is open.

D installed on the system on the branch circuit.

⑸ separate filter systems: hydraulic system can separate hydraulic pump and oil filter form an independent filter circuit.

In the hydraulic system in addition to the system as a whole needed to filter out, often in a number of important elements (such as precision Throttle servo valve, and so on) in front of a dedicated fine oil filter is installed separately to ensure that they work properly.
