What should I do if the secondary water supply pressure in the community is unstable?

What is the reason for the high and low water pressure of secondary water supply?

1. Check whether the voltage of the water supply system and the source of water inflow are normal. If the voltage is unstable and the water inflow is abnormal, the water supply pressure will also be unstable.

2, check whether the water supply system pump configuration is appropriate. Because the flow, lift and number of pumps are directly proportional to the water supply. If the water pump is not properly configured, the secondary water supply pressure will be unstable.

What is the reason for the high and low water pressure of secondary water supply?

3. If the system adopts the air pressure tank water supply mode and the pressure acquisition point is selected on the air pressure tank, it may also lead to the flexibility of the oscillating gas of the system. Moreover, the dissolution pressure of gas in water changes, and there is a certain time difference between the feedback pressure of water pump and the feedback pressure of gas passing through it, which causes system oscillation. Non-negative pressure water supply equipment and frequency conversion water supply equipment are newly developed products, which are much better than air pressure water supply. )

4. The reason why the acceleration and deceleration time of the controller is inconsistent with the power of the water pump motor. Generally speaking, the greater the power, the longer the acceleration and deceleration time, and the pressure position collected by the pressure sensor does not match the flow rate, so the pressure value fed back to the controller is high or low. Or the acceleration and deceleration time of the controller and the frequency converter are inconsistent, and the acceleration and deceleration time of the controller should be set to be greater than or equal to that of the frequency converter. All these will cause the oscillation of water supply system, so it is very important to choose suitable pumps and water supply equipment for secondary water supply in high-rise buildings.

If the above methods still can't be solved, it may be that the design flow and lift of secondary water supply equipment are unreasonable during the selection, or there is no water supply in different zones, resulting in insufficient water pressure in high zones or too high water pressure in low zones. It is suggested to consult the manufacturer's customer service online, explain the situation in detail and solve the problem in a targeted manner.
