1. Assess vibration and sound status

Objective: To identify potential faults through vibration and sound.

Implementation: Use vibration detection tools to measure the vibration amplitude of the pump body and motor shaft, and monitor the sound of the pump during operation, and pay attention to any abnormal metal friction or percussion sound.

Note: The vibration and sound characteristics of each assessment are recorded for comparative analysis and timely detection of potential hazards.

 

2. Monitor bearing temperature condition

Objective: To prevent failure due to overheating of bearings.

Implementation: Using infrared temperature measurement or contact temperature measurement method regularly check the bearing housing temperature to ensure that it is in the safe range.

Note: Once the temperature is found to be abnormally high, it should be stopped immediately and inspected deeply to prevent bearing damage.

 

3. Manage lubricating oil status

Objective: To ensure good lubrication of bearings.

Implementation: Check the oil level through the oil window or oil level gauge, and observe the quality of the oil to determine whether it needs to be replaced.

Note: Use the specified lubricating oil, replace and clean the tank and oil circuit regularly to prevent pollution.

 

4. Monitor import and export pressure and flow

Objective: To evaluate pump performance to ensure production requirements are met.

Implementation: Use pressure gauge and flowmeter to measure the inlet and outlet pressure and flow of the pump, and compare with the design value.

Note: If large deviation is found, the reasons should be analyzed and corresponding measures should be taken.

 

5. Check sealing and cooling efficiency

Objective: To ensure tight seal of pump shaft and efficient cooling system.

Implementation: Check the wear of mechanical seal or packing seal to ensure the smooth flow of cooling water.

Note: When the seal leaks or the cooling effect decreases, the seals should be replaced in time or the cooling system should be cleaned.

 

6. Confirm the running state of the motor

Objective: To ensure stable motor drive and efficient pump operation.

Implementation: Monitor the motor current and voltage, observe whether the motor runs smoothly, no abnormal heating.

Note: When the motor is abnormal, it is necessary to cooperate with the electrician for professional diagnosis and treatment.

 

7. Follow the prescribed maintenance process

Objective: Standardize maintenance operation, improve maintenance efficiency and quality.

Implementation: Disassembly, inspection, repair and assembly in order according to maintenance manual or internal procedures.

Note: Record the key data of each step to facilitate follow-up tracking and debugging.

 

8. Follow maintenance safety procedures

Objective: To ensure the safety of personnel and equipment during maintenance.

Implementation: Perform power outage, listing and locking procedures, wear personal protective equipment, and prepare necessary maintenance and safety tools.

Note: Strictly follow the safety operation procedures to ensure the safety of the inspection area.

             In summary, the maintenance and repair of self-balancing multistage pump is a comprehensive work, requiring technicians to have deep professional knowledge, rigorous work attitude and a high degree of safety awareness. Through careful inspection and maintenance, the service life of the pump can be significantly improved to ensure the stable operation of the production line.
