The filter OF3-08-3R is a specially designed filter element for the inlet of EH oil circulation pump. Its main function is to improve the quality of oil flow and filter out impurities in fire-resistant fuel. In the return oil filter of the fire resistant fuel circulation pump, a bypass one-way valve needs to be installed to avoid deformation caused by oil pressure when the filter is blocked. When the pressure difference between the inlet and outlet of the return oil filter is greater than the set value (0.5MPa), the one-way valve will act, short circuiting the filter to ensure the normal operation of the fire-resistant fuel system.

The installation position of the filter OF3-08-3R is crucial as it directly affects the inlet oil quality of the EH oil circulation pump. In the fire resistant fuel system, the combustion of fuel can produce a large amount of impurities, such as carbon black, metal shavings, etc. These impurities can affect the operation of the EH oil circulation pump and even lead to equipment failure. Therefore, using a filter element can effectively prevent these impurities from entering the system, ensuring its cleanliness and normal operation.

The structural design of the filter OF3-08-3R is also very reasonable. It usually adopts a multi-layer filter structure, which can effectively filter out various impurities. The material of the filter is usually stainless steel, which has good corrosion resistance and wear resistance, and a long service life. At the same time, the sealing performance of the filter element is also very good, which can prevent oil leakage.

When using the filter OF3-08-3R, it is important to pay attention to its cleaning cycle. Generally speaking, the cleaning cycle of the filter element depends on the cleanliness and flow rate of the oil. When the pressure difference of the filter element reaches the set value, it needs to be cleaned. When cleaning, simply remove the filter element and use appropriate cleaning methods such as cleaning with cleaning agents, high-pressure water jet cleaning, etc., and then reinstall it.

In addition to the cleaning cycle, it is also necessary to regularly check the sealing performance of the filter OF3-08-3R. If any leakage is found in the filter element, it needs to be replaced in a timely manner to avoid affecting the normal operation of the system.

In summary, the application of filter OF3-08-3R in the fire resistant fuel system of EH oil circulation pump is very important. It can effectively prevent impurities from entering the system and ensure the normal operation of the system. At the same time, its structural design is reasonable, easy to use and maintain, which can improve the reliability and stability of the system. During use, it is important to pay attention to the cleaning cycle to ensure the normal operation of the filter element.
