صافی و فیلتر هیدرولیک چیست؟
The hydraulic strainer and filter is a part of the hydraulic systems that prevents contamination and additional substances in the hydraulic oils from entering the device. This filter is produced in two types, low pressure and high pressure, and each of them is installed in different parts of hydraulic systems.
مشخصات فنی صافی و فیلتر هیدرولیک
Hydraulic filters protect your hydraulic system equipment from damage caused by particles in oils or other hydraulic fluids in use. On average, every minute, approximately one million particles larger than 1 micron (0.001 mm or 1 micrometer) enter a hydraulic system. The precise performance of hydraulic systems depends on high-precision machined parts, which are their worst enemy. , hydraulic fluid pollution. It should be noted that pollution can be solid, liquid or gas. Filters or hydraulic filters are one of the equipment and requirements of hydraulic systems, which include a porous wire screen to separate larger particles and a dense and large paper or cellulose network to separate small particles from the hydraulic fluid. Filters are usually installed in the circuit above valves, pumps or other equipment. To protect them from the harmful effects of the system and to ventilate the circuit using the ventilation screw embedded in the strainer.
نحوه کارکرد فیلتر هیدرولیک
In hydraulic filters, the suction or return of the hydraulic fluid is from the top of the filter and the inlet port, and the outlet of the filter is below it so that the refined oil returns to the tank from under the filter. A return path to the pump with a safety valve is also installed next to the inlet port so that if the filter is removed from the circuit, the pump circuit will not be without fluid. In the oil inlet and outlet pressure line filters, both are above the filter and opposite each other, that is, the hydraulic fluid enters the filtration chamber from the inlet opening and collects around the filter element, and after passing through the paper layer of the filter element and being purified, It moves from inside the filter element to the outlet opening and leaves the filtration chamber and filter.

مزایای فیلتر هیدرولیک
The use of good and appropriate filtration in the hydraulic system can provide good protection of the hydraulic system and equipment and increase the life and durability of the equipment and reduce the maintenance costs of the hydraulic system.
