Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The vacuum meter is used to measure the vacuum degree of the water pump before the water pump pumping, and to a certain degree of vacuum, the water can be sucked into the upward pressure position of the pump.A pressure gauge is used to indicate that the pumping is pressure in the pipe. The size of the pressure is related to the lift head, pipe diameter, atmospheric pressure and so on.
The water pressure (vacuum) is measured by the vacuum meter. The pressure gauge is used to measure the pressure at the water end, and the difference between the two is the lift of the pump
The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.
