 The method of replacing the Pall hydraulic oil filter usually includes the following steps:
1. Park and cut off the power:
Ensure that the equipment is in a safe state to prevent accidents during the replacement process.
2. Block the oil port valve:
Close the inlet ball valves and other valves related to the hydraulic oil filter element to ensure that the hydraulic oil in the system does not flow out and to prevent impurities from entering.
3. Discharge hydraulic oil:
Open the discharge port at the bottom of the filter and the vent valve at the top to drain the hydraulic oil inside the filter completely. This step is to reduce oil overflow when replacing the Pall hydraulic oil filter element and maintain a clean working environment.
4. Disassemble the old filter element:
Use a suitable tool (such as a wrench) to open the cover of the hydraulic filter.
Loosen the fastening nut on the upper end of the Pall hydraulic oil filter element and carefully remove the old filter element. During this process, it is important to avoid dust or other impurities from entering the system.
5. Clean the filter:
Before installing a new filter element, ensure that the inside and connection parts of the filter are clean and free of residual old oil or impurities.
6. Install a new Pall hydraulic oil filter element:
Install the new filter element correctly into the filter, ensuring that the sealing ring is properly padded to prevent hydraulic oil leakage.
Tighten the fastening nut on the upper end of the filter element to ensure that it is firmly fixed.
7. Close the discharge port and vent valve:
Tighten the drain plug and the screw of the vent valve to ensure good sealing of the system.
8. Check the sealing:
Reinstall the cover of the hydraulic filter and tighten the fixing screws.
Check for leaks in the hydraulic system and ensure that all connecting parts are well sealed.
9. Start the hydraulic system:
After confirming that all steps have been completed correctly, start the hydraulic system.
Check if the system is working properly and pay attention to any abnormal sounds or movements.
10. Subsequent maintenance:
Regularly inspect and replace hydraulic oil to maintain its cleanliness and extend the service life of the filter element.
Pay attention to checking the condition of the return oil filter, suction filter, and pilot filter to ensure that they are all in good condition.
Please note that different types and brands of hydraulic oil should not be mixed to avoid reaction deterioration or adverse effects. When replacing the filter element, it is important to ensure that all operations comply with safety regulations to prevent accidents.
