Zusammenfassung: | A livestock breeding water supply system comprises a control box and a water supply network. A PLC, a frequency converter, an operating platform, a displayer and an alarm are installed in the control box. A pressure sensor, a speed regulating water pump motor and a constant-speed water pump motor are installed in the water supply network. The pressure sensor is connected to the PLC through an electric conductor, the PLC is connected to the frequency converter through an electric conductor, the frequency converter is connected to the speed regulating water pump motor through an electric conductor, the PLC is connected to the speed regulating water pump motor through an electric conductor, and the operating platform, the displayer and the alarm are connected to the PLC through electric conductors. The rotating speed of a water pump is automatically changed and water pressure is kept constant through the changes of the water use amount and the water pressure to meet water use needs, the livestock breeding water |
