Frequency constant pressure water supply system pressure instability what are the reasons?

Constant pressure water supply system is the water supply network in the water changes, the outlet pressure remains the same water supply. If the pressure of water supply system pressure instability, there may be the following reasons: Variable pressure water supply system pressure instability What are the reasons? 1, the pressure sensor (pressure transmitter or remote pressure gauge) collection system pressure position is not reasonable, the pressure collection point selected from the pump outlet too close, the pipeline pressure is too much affected by the velocity of the water flow. Which feedback to the constant pressure water supply controller pressure value fluctuated, resulting in system oscillation. 2, if the system uses a pressure tank, and the pressure collection point selected in the pressure tank, may also cause system oscillation. The air itself has a certain degree of scalability, and gas solubility in water changes with pressure changes, the pump direct water feedback pressure and pressure feedback gas through a certain time difference, resulting in system oscillation. 3, constant pressure water supply controller acceleration and deceleration time and pump motor power does not match. Under normal circumstances, the greater the power, the acceleration and deceleration time will be longer. This parameter allows users to select more than one data for debugging. For example, 15KW is generally between 10 to 20 seconds. 4, Inverter constant pressure water supply controller and inverter acceleration and deceleration time is inconsistent, inverter constant pressure water supply controller acceleration and deceleration time setting should be greater than or equal to the inverter acceleration and deceleration time.
