Water pump anti-freezing control system and control method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and relates to a water pump antifreeze control system and a control method thereof. Background technique [0002] In the cold winter, the outdoor temperature is very low, even lower than the freezing point, so the outdoor water pump often freezes, and the water in the pump water chamber freezes in the water chamber because it is not discharged, and the volume expands after freezing. Cause the water chamber of the water pump to rupture. In order to prevent the water pump from being damaged by freezing, the methods currently used mainly include: a. Place a heat-generating antifreeze device near the water pump, and heat the water pump to prevent it from being frozen; b. Set the water pump indoors. The outdoor temperature is relatively high and it is not easy to drop below zero, so the water pump can be properly prevented from freezing, but in most cases it is difficult to install the water pump...

AI Technical Summary

Problems solved by technology

Although the above-mentioned technical solution can achieve the anti-freezing and cracking purpose of the water pump, its structure is relatively complicated compared to the existing water pump, and more pipelines and valves are added, which makes the structure more complicated and greatly increases the cost. And there are also cases where the pump runs dry
