Centrifugal pump start method

Centrifugal pump start method, centrifugal pump start note
  Before the start of the centrifugal pump is ready, open the diversion gate, so that the front tank to the design level, you can start the pump.
Centrifugal pump start Note:
When starting the centrifugal pump, the staff will have to leave the unit at a certain distance. For centrifugal pumps and volute mixed flow pump, usually closed valve start, standby group speed reaches the rated value, you can open the vacuum gauge and the pressure gauge on the valve, this time, the pressure gauge reading should rise to the pump flow is zero When the maximum value, then you can gradually open the pressure on the pipeline valve. If there is no exception, then the vacuum gauge reading will gradually increase, the pressure gauge reading should be gradually decreased, the motor ammeter reading should be gradually increased. Start the work until the valve is fully open, that is completed. In the closed valve should be noted that the valve running time should generally not exceed 5 minutes, such as the time is too long, the pump liquid heat, may cause accidents.
  For self-priming pumps, vertical axial flow pump and guide vane mixed flow pump, usually open the valve. While filling the rubber bearing, while the motor can start, until the speed reaches the rated value, stop filling water, that is, to complete the start work.
