The steps for stopping a slurry pump are as follows:
1. Close the outlet valve: When preparing to stop the pump, first gradually close the outlet valve of the slurry pump. This operation can avoid water hammer caused by sudden shutdown, which may damage the pipeline and pump body. At the same time, it can reduce the load of the pump and make the shutdown process smoother.
2. Stop the motor: After closing the outlet valve, press the motor stop button to cut off the power supply and stop the motor. At this time, pay attention to the stopping of the motor to ensure that the motor stops completely.
3. If the slurry pump needs to stop running for a long time, the slurry in the pump and the pipeline must be drained cleanly. Because the slurry may solidify after precipitation, it may damage the pump parts when it is started again.
4. Close the inlet valve: After discharging the slurry, close the inlet valve to prevent external substances from entering the pump body.
5. Do a good job of maintenance: After shutdown, perform necessary inspections and maintenance on the slurry pump, such as checking the condition of seals, bearings and other components, to prepare for the next operation.
