The replacement cycle of the ZX160*100 inlet filter element of the EH main oil pump for steam turbine fire-resistant oil depends on various factors, and the recommended replacement cycle range is usually:

According to the working hours, it is generally between 6 months and 1 year.

According to the oil analysis results, when the accumulation of impurities reaches a certain level, it is necessary to replace the inlet filter element ZX160 × 100 of the EH main oil pump.

3. According to the contamination situation of the EH main oil pump inlet filter ZX160 × 100, when the EH main oil pump inlet filter ZX160 × 100 is damaged or severely blocked, it needs to be replaced.

4. Depending on the operating conditions, a shorter replacement cycle is required for frequent startup and shutdown.

5. According to the oil conditions, new oil requires a longer replacement cycle, while old oil requires a shorter replacement cycle.

6. It is recommended not to extend the replacement cycle.

 

EH main oil pump inlet filter ZX160 × 100 main function:

1. Purify the incoming fuel by removing insoluble impurities, particulate matter, corrosive substances, and other substances to ensure that the fuel reaching the hydraulic engine meets the requirements.

2. Isolate moisture, prevent moisture from entering the hydraulic engine, and protect the hydraulic engine from moisture corrosion.

3. Provide clean fuel for the hydraulic engine to ensure the cleanliness and long-term use of its components.

4. Effectively extend the replacement cycle and reduce the maintenance cost of the filter element.

EH main oil pump inlet filter ZX160 × 100 features:

Using a filtering accuracy of 10 μ m can effectively remove the vast majority of impurities larger than 10 μ m.

2. Adopting a multi-stage filtration design, there is first a mesh filter followed by filter paper filter, and then purified through the oil circuit to ensure the cleanliness of the discharged fuel.

3. Using filter paper, it has high permeability and ultra-high filtration efficiency.  

4. Adopting patented XJH composite sealing design to prevent fuel leakage.

5. Built in oil absorbing paper effectively absorbs moisture.

6. Adopting high temperature and pressure resistant materials, suitable for high temperature and high pressure environments.
