HaiTe Filter Return Oil Filter RFA Series Micro Direct Return Oil Filter Manufacturer

Description :

RFA Direct Return Oil Filter Product Introduction:

RFA direct return oil filter is used for precision filtration of hydraulic system return oil, filtering out metal particles generated by component wear and rubber impurities of seals in the hydraulic system, and keeping the oil flowing back to the tank clean. The filter is installed at the top of the fuel tank, with the cylinder partially immersed in the tank and equipped with a bypass valve, filter element pollution blockage transmitter, and other devices. It has the advantages of compact structure, easy installation, high oil flow capacity, low pressure loss, and convenient replacement of the filter element.

Performance characteristics of RFA direct return oil filter:

1. Easy installation and connection, simplifying system piping: This filter is directly installed on the fuel tank cover plate, with the filter head exposed outside the tank and the return cylinder immersed in the tank. The RFA direct return oil filter inlet is equipped with pipe and flange connections, simplifying the system piping. Make the system layout more compact and the installation and connection more convenient.

2. Install a filter pollution transmitter and an oil circuit bypass valve to improve the reliability of the hydraulic system; When the filter element is blocked by pollutants or the system liquid temperature is too low, flow pulsation and other factors cause the inlet oil pressure to be 0.35Mpa, the signaling device will send a signal indication. The filter element should be replaced or the oil temperature should be increased in a timely manner. When it is not possible to immediately shut down and deal with these faults, the bypass valve located at the bottom of the filter element will automatically open (the opening pressure of the bypass valve is 0.4Mpa) to protect the normal operation of the filter and hydraulic system.

3. The design adopts a direct return oil filter, making it very convenient to replace the filter element or add oil to the fuel tank; Simply unscrew the filter cover (cleaning cover) to replace the filter element or add oil to the fuel tank. There are 2 M18 × 1.5 oil ports on the filter head, which can be used to install a transmitter on either side or to filter a small amount of oil in the system back into the fuel tank.

4. It has a liquid flow set at the bottom of the oil return cylinder, which can smoothly allow the medium of the oil return to flow into the oil tank without easily generating bubbles, thereby reducing the re-entry of air and weakening the disturbance of deposited pollutants. 5. The filter element is made of fiberglass filter material; It has the advantages of high filtration accuracy, large oil flow capacity, small original pressure loss, and large pollutant absorption capacity. The filtration accuracy is calibrated based on filtration precision, with filtration ratios β 3, β 5, β 10, β 20 ≥ 200, and filtration efficiency η ≥ 99.5%. The evaluation methods are ISO16889-99 and GB/T18853-2002.
