Self-priming pump control system

Abstract

The invention relates to a self-priming pump control system. The self-priming pump control system comprises a pipeline water pressure threshold module, a pipeline water tower module, a water tower water supply recording module, a pressure increasing towerless module and a switching module. A water supply stopping water pressure threshold and a water supply starting water pressure threshold are preset. The pipeline water tower module is used for supplying water to a water supply pipeline and stopping water supply until the water pressure in the water supply pipeline reaches the preset water supply stopping water pressure threshold and supplying water when the water pressure in the water supply pipeline is smaller than the water supply stopping water pressure threshold. A water tower water supply interval time threshold is preset, and water supply times when the interval time of two times of adjacent water supply is smaller than the water supply interval time threshold during water supply of the pipeline water tower module are recorded; water supply is stopped when the water pressure in the water supply pipeline reaches the water supply stopping water pressure threshold, and water issupplied when the water pressure in the water supply pipeline is lowered to the water supply starting water pressure threshold; and the pipeline water tower module or the pressure increasing towerless module is switched to by using the switching module to supply water to the water supply pipeline. By the adoption of the self-priming pump control system, the frequent starting and stopping of a self-priming pump can be reduced, and the service life of the self-priming pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a self-priming pump control system. Background technique [0002] Existing self-priming pumps, such as the authorized announcement number CN208651188U, disclose an energy-saving and environment-friendly outdoor self-priming pump for a self-priming pump control system, including a pump body, a motor and a base, and the pump body and the motor are fixedly connected by a pump bracket.

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing technical solutions have the following defects: in the process of using the above-mentioned self-priming pump, in the process of replenishing water to the water supply pipeline outside the building, the pressure of the self-priming pump to replenish water is constant, and the inside of the water supply pipeline The water pressure is constant. Once the water supply pipeline leaks and the water supply pipeline is depressurized, the self-priming pump needs to re-supply the water supply pipeline to make the water pressure inside the water supply pipeline reach the preset value again. In this process, due to the leakage of the water pipe, the water pressure in the water supply pipeline is repeatedly released. Therefore, during the water supply process of the self-priming pump, in order to keep the water pressure in the water supply pipeline at the preset value, there will be frequent start and stop, which will easily lead to a reduction in the service life of the self-priming pump
