Constant-pressure water supply system
The invention provides a constant-pressure water supply system, and relates to the technical field of constant-pressure water supply. The constant-pressure water supply system comprises a pool, a water level sensor and a control system, the water level sensor is electrically connected with the control system, the control system comprises a regulator, a PLC control machine and a frequency converter, the output end of the PLC control machine is in communication with the input end of the frequency converter, the output end of the frequency converter is connected with water pumps, and the water pumps comprise the main water pump and the standby water pump, and pressure sensors and rotating speed sensors are installed at the output ends of the main water pump and the standby water pump. According to the constant-pressure water supply system, the PLC control system is utilized to enable the frequency converter to circularly control the main water pump and the standby water pump, so that the constant water pressure of a pipe network, the soft start of a water pump motor and the switching between the variable-frequency water pump and the power-frequency water pump are realized, the pressure sensor is used for detecting water pressure information of a water outlet of the main water pump and sending the water pressure information to the PLC control machine, the whole constant-pressure water supply system is simple in structure, waste of water resources is avoided, damage of water flow to water utilization equipment is reduced, and practicability is high.
