A self-priming pump control system

Abstract

The invention relates to a self-priming pump control system, which includes a pipeline water pressure threshold module, which is preset with a water supply stop water pressure threshold and a water supply start water pressure threshold; a pipeline water tower module, which is used to replenish the water supply pipeline until the water supply pipe When the water pressure in the road reaches the preset water supply stop water pressure threshold, the water replenishment will be stopped, and the water supply will be replenished when the water pressure in the water supply pipeline is lower than the water supply stop water pressure threshold; the water tower water supply recording module has a preset water tower water supply interval time threshold , record the number of water supply times when the interval between two adjacent water supplies is less than the water supply interval threshold when the pipeline water tower module is supplying water; the pressurized no-tower module stops only when the water pressure in the water supply pipeline reaches the water supply stop water pressure threshold Water replenishment, the water pressure in the water supply pipeline is reduced to the threshold value of the water supply pressure for water supply; switch modules, switch to the pipeline water tower module or booster without tower module to supply water to the water supply pipeline. The invention can reduce the frequent start and stop of the self-priming pump and increase the service life of the self-priming pump.

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. The rotating shaft of the motor extends into the pump body and is fixedly connected with the impeller. The pump body and the motor are fixedly installed on the base. The upper end of the pillar is fixed with a solar panel, the upper end of the side wall of the battery box is provided with a charging interface, the lower end of the charging interface is provided with a power display, and the lower end of the power display is provided with a switch button, and the motor, storage battery, solar...

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
