How to Maintain an Oil Pump?

After a long period of usage, oil pumps require regular maintenance to extend their service life. Here are some steps for normal daily maintenance of an oil pump: 1. Check if there are any looseness in the pump pipes and connections. Rotate the pump by hand to see if it moves smoothly. 2. Add lubricating oil to the rolling bearing body and ensure the oil level is at the bottom line of the oil mark. Replace or refill the grease immediately if necessary. 3. Open the oil plug of the gear oil pump casing and inject or drain the oil. 4. Close the shut-off valve of the outlet line and tighten the pressure gauge at the inlet and outlet. 5. Start the motor and check if it rotates properly. 6. After the thermal oil pump operates normally, slowly open the shut-off valve while monitoring the motor load. 7. Operate the high-temperature thermal oil pump within the flow rate and head range specified on the nameplate to ensure efficient operation and achieve energy-saving and environmental protection. 8. The temperature of the rolling bearing should not exceed 35°C during operation, and the maximum temperature should not exceed 80°C. 9. If any abnormality is found in the pump, stop and check the cause of the fault. 10. Before stopping the pump, close the shut-off valve and pressure gauge, and then stop the motor. 11. Replace the lubricating oil after 100 minutes of operation within one month, and then replace it every 500 minutes. 12. Regularly adjust the packing gland to ensure proper leakage in the packing chamber. A drip leakage is preferred. 13. Regularly check for damage to the shaft sleeve. Replace it immediately if the damage is severe. 14. In cold winter use, after starting the pump, open the water plug under the pump casing to discharge any substances and prevent freezing. 15. When the pump is not in use for a long time, disassemble all the pump parts, wipe off any water, apply grease to rotating and mating parts, and store them properly. 16. Keep each part of the pump and replace with identical parts. When disassembling and inspecting the thermal oil pump, keep each part properly. Pay special attention to explosion-proof parts and avoid damaging or scratching them. If there is any damage, replace it with a new identical part. Do not use substitute materials with lower performance or parts that do not meet the original specifications. During assembly, make sure all parts are installed in their original positions without missing any.
