Ensure safe operation:
Power off and pressure release: Before replacement, ensure that the equipment has been powered off and the pressure in the hydraulic system has been completely released to prevent the danger of high-pressure liquid ejection.
Wear protective equipment: Wear appropriate personal protective equipment, such as gloves and protective glasses, to avoid contact with oil or sharp mechanical parts.
Use suitable spare parts:
Original parts or qualified substitutes: Ensure that the replacement parts are original parts that match the model of the gear pump, or certified high-quality substitutes, avoiding the use of inferior or mismatched parts.
Cleaning and inspection:
Clean the working area and pump body: Before replacing parts, clean the surrounding oil, impurities, and dust to keep the working area clean to prevent impurities from entering the pump and affecting the performance of the equipment.
Inspect damaged parts: Removed old parts should be carefully inspected for damage causes, such as wear, corrosion, cracks, etc., to assess the overall health of the pump.
Correct disassembly sequence:
Sequential disassembly: When disassembling parts, it is necessary to operate according to the specified steps to prevent accidental disassembly and unnecessary damage, especially precision parts such as bearings and gears.
Avoid too tight or too loose: When installing new parts, ensure that the torque value of fasteners such as bolts and nuts meet the requirements to avoid affecting the sealing and operating stability of the equipment due to too tight or too loose.
Lubrication and sealing:
Lubricate key components: During reassembly, ensure that all moving parts such as gears, bearings, etc. are fully lubricated to avoid wear caused by dry wear.
Check the seals: If the seals (such as O-rings, gaskets, etc.) are aging, damaged, etc., they must be replaced to ensure the sealing of the pump and prevent internal or external leakage.
Debugging and testing:
Check before power-on: After the replacement is completed, manually rotate the pump shaft to ensure that there is no stuck or abnormal sound, and check whether all connections are firm.
Power trial operation: low-speed trial operation after power on, check whether there is abnormal noise, vibration, leakage and other abnormal phenomena, to ensure that everything is normal before it can be formally put into use.
Record and maintenance:
Record the replacement: record the replaced parts and the operation process, including the part model, replacement time, working condition, etc., to facilitate future maintenance and tracking of service life.
Regular maintenance: After replacing the parts, regular inspection and maintenance of the equipment should be strengthened to ensure that the pump is always in good working condition.
