The RFA oil return filter is used to filter the oil return of the hydraulic system. It filters out the metal particles produced by the wear of the components in the hydraulic system and the rubber impurities of the seals and other pollutants, so as to keep the oil flowing back to the oil tank clean.
The RFA oil return filter is used to filter the oil return of the hydraulic system. It filters out the metal particles produced by the wear of the components in the hydraulic system and the rubber impurities of the seals and other pollutants, so as to keep the oil flowing back to the oil tank clean. The filter is installed on the top of the oil tank, the cylinder is partially immersed in the oil tank, and is equipped with devices such as bypass valve, diffuser, filter pollution blocking signal, etc. It has compact structure, convenient installation, large oil passing capacity, small pressure loss, and replacement The filter is convenient and so on.
1. Easy installation and connection, simplifying the system pipeline:
The filter is directly installed on the oil tank cover, the filter head is exposed outside the oil tank, the oil return cylinder is immersed in the oil tank, and the oil inlet is provided with pipe and flange connections, thereby simplifying the system pipeline. The system layout is more compact, and the installation and connection are more convenient.
2. Set the filter element pollution transmitter and oil 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 oil inlet pressure to be 0.35Mpa, the signalling device will send a signal indication. The filter element should be replaced in time or the oil temperature should be increased. In this case, when it is not possible to stop the machine immediately to deal with these faults, the bypass valve located at the lower part of the filter element will automatically open and work (the opening pressure of the bypass valve is 0.4Mpa) to protect the filter and the hydraulic system from working normally.
3. The design adopts straight-back oil filter, which makes it convenient to replace the filter element or refuel the oil tank;
Just unscrew the filter cover (cleaning cover) to replace the filter element or add oil to the oil tank, and there are 2 M18×1.5 oil ports on the filter head, which can install a transmitter on either side or a small amount of oil flow in the system Return to the tank for filtering.
4. With flow diffuser
The diffuser is arranged at the bottom of the oil return cylinder, which can make the oil return medium flow into the oil tank smoothly, and it is not easy to generate air bubbles, thereby reducing the re-entry of air.
5. The filter element is made of glass fiber filter material;
The RFA oil return filter has the advantages of high filtration precision, large oil passing capacity, small original pressure loss, and large dirt holding capacity.
1. Metallurgy: used for the filtration of the hydraulic system of rolling mills and continuous casting machines and the filtration of various lubrication equipment.
2. Petrochemical: separation and recovery of products and intermediate products in the process of refining and chemical production.
3. Textile: Purification and uniform filtration of polyester melt in the process of drawing, protection and filtration of air compressors, and degreasing and dehydration of compressed gas.
4. Thermal power and nuclear power: oil purification of gas turbine, boiler lubrication system, speed control system, bypass control system, purification of feed water pump, fan and dust removal system.
