What safety precautions should be taken when maintaining the water injection pump?

1. Check before starting:
Make sure all maintenance work has been completed and the site is clean.
Check whether the various parts of the pump are normal, ensure that there is no debris in the pump, the friction pair assembly clearance has not changed, and all bolts are tightened reliably.
Check whether the pressure gauge and flow meter are working properly, and the quality and oil level of the lubricating oil should meet the specified requirements.
2. Electrical safety:
Check whether the motor and control circuit are intact and ensure that the motor is reliably grounded.
Use a megohmmeter to measure the insulation resistance of the motor to ensure that it is within the safe range.
3. Valve status:
Check the status of all valves to ensure that the inlet valve, outlet valve and return valve are in the correct position to ensure that the pipeline is unobstructed.
4. Protective measures:
Before starting, ensure that the operator wears appropriate protective equipment, such as safety shoes, gloves and goggles.
No maintenance or repair work should be performed when the equipment is running to ensure safety.
5. Leakage check:
Check whether there is leakage at the pump body and pipeline connections, and deal with any problems immediately.
6. Precautions during startup:
When starting the pump, ensure that all personnel stay away from the front and sides of the pump to avoid accidents when the pump is started.
After starting, observe the operating status of the pump and check whether there is any abnormal vibration or noise. If any abnormality is found, stop the pump immediately for inspection.
7. Maintenance after stopping the pump:
After stopping the pump, cut off the power supply and close all valves to ensure safety.
Pumps that have been out of service for a long time should be cleaned and treated with anti-corrosion to ensure that the pump body and pipelines are dry.
8. Regular training:
Regularly conduct safety training for operators to improve their safety awareness and emergency handling capabilities.
