Maintenance and service during operation
1. The water piping must be highly sealed.
2. It is forbidden to run the pump for a long time in the state of cavitation.
3. It is forbidden to run the motor overcurrent for a long time when the pump is running at flow rate.
4. When regularly checking the operation of the pump, the motor overcurrent runs for a long time.
5. The pump should be supervised by someone in operation to avoid accidents.
6. The pump should be refueled every 500 hours of operation. Motor power greater than 11KW is equipped with a refueling device, which can be directly injected with a high-pressure oil gun to ensure excellent bearing lubrication.
7. After the pump has been running for a long time, due to mechanical wear, the noise and vibration of the unit should be stopped and checked. If necessary, the wearing parts and bearings can be replaced. The overhaul period of the unit is generally one year.
Mechanical seal maintenance and maintenance
1. The mechanical seal lubrication should be clean and free of solid particles.
2. It is strictly forbidden to work the mechanical seal under dry grinding.
3. The pump (motor) should be turned a few times before starting to avoid the sudden start causing the seal ring to break and damage.
