Water pump shutdown control method, device and system based on water temperature rising rate

Abstract

The invention discloses a water pump shutdown control method based on the water temperature rising rate. The water pump shutdown control method comprises the following steps of acquiring temperature rising data; comparing the temperature rising data with a preset temperature rising threshold value to form a comparison result; and controlling a water pump to shut down according to the comparison result. According to the technical scheme that shutdown protection is carried out based on water temperature in the prior art, the water temperature data are compared with the preset shutdown stem to judge whether shutdown protection needs to be carried out or not, and technicians in the related fields all neglects the problem that a great deal of energy consumption and machine consumption can be caused through the method. In order to solve the technical problem neglected by the technicians in the related fields, the water pump shutdown control method is provided for judging whether to carry outshutdown protection or not according to the comparison result obtained by comparing the temperature rising data with the temperature rising threshold value; and accordingly, the time for judging whether to carry out shutdown protection or not is greatly shortened, and energy consumption and machine consumption are reduced.

Description

technical field [0001] The invention relates to the field of water pump control, in particular to a method, device and system for controlling water pump stoppage based on the water temperature rise rate. Background technique [0002] Water pumps are widely used in daily life. The water pump continues to work in the absence of water, which will not only cause energy loss, but also cause the system to overheat and thus accelerate wear. The following solutions are proposed in the prior art to solve this problem: [0003] 1. A water flow switch is installed at the water outlet of the water pump, and the water flow switch is used to detect whether the water pump is out of water, and the shutdown protection is performed according to the detection result. However, in practical applications, the water flow switch is easily stuck by foreign objects in the water, so that the water flow switch cannot correctly detect whether there is water flowing at the water outlet, and this situatio...

AI Technical Summary

Problems solved by technology

However, in practical applications, if the preset water temperature is high, the pump needs to run idle for a period of time to reach the preset temperature, which will still cause a lot of energy consumption and mechanical consumption. If the preset water temperature is low, it is vulnerable to environmental and water sources. The influence of temperature causes misjudgment, so that the water pump cannot work normally; and the arrival protection time is inconsistent with different initial water temperatures, so that the staff need to adjust the preset temperature in real time as the environment changes, otherwise the effect of shutdown protection cannot be achieved, such as preset The temperature is 80°C. In summer, the initial water temperature is high, and it takes 30 minutes to reach the preset temperature from the initial water temperature. In winter, the initial water temperature is low, and it takes one hour to reach the preset temperature from the initial water temperature, that is, the water pump needs to be idling for one hour to reach Preset temperature for shutdown protection

[0005] It can be seen from the above that technical personnel in related fields often ignore the technical solution of preset water temperature upper limit for shutdown protection, which still has the defects of wasting energy and weak protection for water pumps
