HC4704 series—HC4704FKP8H Pall filter element introduction:
The pall filter element should be installed at the suction port of the pump:
A surface-type oil filter is generally installed on the suction line of the pump to filter out larger foreign particles to protect the hydraulic pump. In addition, the filter capacity of the oil filter should be more than twice the pump flow rate, and the pressure loss should be less than 0.02MPa.
(1) The pall filter element is installed on the outlet oil circuit of the pump:
The purpose of installing the oil filter here is to filter out pollutants that may invade valves and other components. Its filtration accuracy should be 10-15μm, and it can withstand the working pressure and impact pressure on the oil circuit, and the pressure drop should be less than 0.35MPa. At the same time, a safety valve should be installed to prevent clogging of the oil filter.
(2) The pall filter element is installed on the oil return line of the system:
This installation acts as an indirect filter. Generally, a back pressure valve is installed in parallel with the filter. When the filter is blocked and reaches a certain pressure value, the back pressure valve opens.
(3) The pall filter element is installed on the branch oil circuit of the system.
(4) Pall filter element separate filtration system:
Large hydraulic system can be specially equipped with a hydraulic pump and oil filter to form an independent filter circuit. In addition to the oil filter required by the entire system, the pall filter element hydraulic system is often used in some important components (such as servo valves, precision throttle valves, etc.) A special oil filter is installed separately in front of the to ensure their normal operation.
