The prefabricated pump station adopts pressure sensor to realize the automatic control operation of the pump station liquid level.
9. Intelligent bottom design
The intelligent bottom of the designed prefabricated pump station adopts a concave structure, which can resist the pressure of groundwater without deformation, and at the same time, only a small amount of sewage is allowed to stay in the pump pit. When the pump is started again, the large flow rate near the pump pit can achieve the self-cleaning effect, avoiding manual dredging.
10. Control cabinet
With various intelligent sensors, it can realize unattended, programming control and remote control. The following control functions can be realized:
(1) Daily release and control the pump station to prevent sedimentation
(2) Anti lock function
(3) Prevent scum
11. Concrete floor

The cylinder of the pump station is made of new material glass fiber reinforced plastic (FRP), and is formed by computer winding once. The main body of the pump station is composed of FRP shaft, water pump, pipeline, valve, sensor, control system, ventilation system and other components.

Changde * * * prefabricated pump station It is the power source to solve the problems of irrigation and drainage, water supply and water resource allocation under the condition of no gravity flow. With the acceleration of national infrastructure construction and urbanization process, the traditional concrete pump station has increasingly exposed its own insurmountable shortcomings. Changde * * * prefabricated pump station The pump station is buried.

Changde * * * prefabricated pump station How does it work?

1. When the pressure of tap water P1 is lower than the set pressure P2 required by the user, the microcomputer will automatically control the soft start operation of the variable frequency pump, until the actual pressure of the pipeline P=P2, the microcomputer will control the variable frequency pump to run at a constant speed. The higher the tap water pressure P1, the lower the speed of the variable frequency pump. The lower the tap water pressure P1, the higher the speed of the variable frequency pump. When the pressure of tap water P1=P2, the variable frequency pump will stop working, which not only makes full use of the original pressure of tap water, but also ensures that the pressure required by users is constant.

2. The water inlet of the variable frequency pump is connected to the steady flow compensator. The microcomputer detects the pressure in the steady flow compensator at all times, and stabilizes the pressure of the steady flow compensator and the inlet water of tap water by controlling the vacuum * * * device to prevent negative pressure, so as to ensure the normal water supply of the tap water pipe network.

3. When the tap water is cut off, the equipment automatically shuts down, the tap water is started, and the power failure automatically restores the normal pressure water supply of tap water. When the tap water voltage is lower than the set value, the microcomputer will automatically control the variable-frequency soft start operation of the water pump, and the water in the booster will be used as a compensation to boost the pressure of the equipment and increase the flow of water to the user. When the pressure of tap water drops to a certain limit, the solenoid valve is closed, and the equipment takes water directly from the booster. The equipment pressurizes to supply water to users, so that the tap water pipe network does not produce negative pressure. The lower the pressure of tap water, the higher the pump speed; on the contrary, the higher the pressure of tap water, the lower the pump speed. When the pressure of tap water is greater than or equal to the top pressure of the society, the variable frequency water pump will stop working, make full use of the original pressure of tap water, and ensure that the user's water pressure is constant.
