1. Pre-start inspection: Make sure the pump is filled with liquid. It is strictly forbidden to start without liquid. Check whether the direction of the pump is consistent with the arrow to avoid reverse operation.
2. Start-up process: Close the outlet valve, check the direction of the pump after connecting the power, and then gradually open the outlet valve to adjust to the required working conditions.
2. Operation monitoring: During operation, continuously observe the pressure, flow rate, temperature and other parameters of the pump to ensure that they are within the normal range. Pay attention to whether there are abnormal sounds or vibrations.
3. Shutdown operation: When shutting down, the rotation speed should be gradually reduced to avoid fluid hammering and pressure surges. After turning off the power, close the valve between the water inlet and outlet.
