Constant pressure pump station

Integrated Water and Fertilizer Equipment - Constant Pressure Pump Station

The Nongsheng Taige constant pressure pump set is a water supply system that uses pressure sensors, PLC, and frequency converters as central control devices to ensure continuous and constant water pressure. Compared to traditional water supply systems, constant pressure pump sets have advantages such as advanced technology, constant water pressure, easy operation, reliable operation, energy saving, and high degree of automation. This system is controlled by an intelligent central processing unit. The pressure controller on the outlet pipe network samples the water pressure and converts it into corresponding electrical signals, which are transmitted to the PLC. The PLC receives the actual pressure signal from the pipe network and compares it with the pressure value set by the user. The deviation value is used to control the output frequency of the frequency converter to change the motor output power. When a water pump runs at full speed but still cannot reach the user set pressure, the variable frequency pump will be switched to power frequency operation, and the frequency converter will soft start another pump and run it at low frequency. If the actual pressure is greater than the set pressure, the power frequency pump will automatically stop to achieve variable constant pressure water supply. If the water consumption is extremely low, stop all main pumps and let the auxiliary pump and pressure tank work at a constant pressure.
