The invention provides a water pump anti-freezing
control system and control method thereof, and belongs to the technical field of water pumps. The
control system and method solve the problems that the anti-freezing technology of an existing water pump is complex and limitation is high. The water pump anti-freezing
control system comprises a flow sensor, a temperature sensor, a
pressure sensor, a displayer and a controller, wherein the flow sensor is arranged on a water pump water inlet, the temperature sensor and the
pressure sensor are arranged at the bottom of a water cavity of a water pump, a
motor shaft of a motor is connected with an
impeller of the water pump, the flow sensor, the temperature sensor and the
pressure sensor are respectively connected with the
signal input end of the controller, and the displayer and the motor are respectively connected with the
signal output end of the controller. The water pump anti-freezing control method includes the steps of (1) sensor detection, (2)
water temperature detection, (3) dry running detection and (4) freezing detection. The water pump anti-freezing control
system and the control method thereof can achieve a water pump anti-freezing function, the structure is simple, practicality is good, and production and use cost is low.
