LEEMIN return oil filter RFA-400 series

Product introduction

The LEEMIN return oil filter RFA-400 series is mainly installed on the oil return pipeline of the hydraulic system. All kinds of dirt such as abrasive particles produced by various hydraulic components during the working process can be trapped by setting the oil return pipeline oil filter to avoid Returning to the fuel tank again, the allowable pressure difference of the oil filter in the return line, according to different pressure levels, ranges from 0.3 to 0.5 MPa.

Performance characteristics

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;

It has the advantages of high filtration precision, large oil passing capacity, small original pressure loss and large dirt holding capacity.

Application field

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.
