Water supply system based on water level induction and pressure induction

Abstract

The invention discloses a water supply system based on water level induction and pressure induction. The water supply system based on water level induction and pressure induction comprises a water tank, a solenoid valve, a water level inductor, a water pump, a pressure inductor and a control module, wherein a water inlet of the water tank is connected with an external tap water pipeline through the solenoid valve; a water outlet of the water tank is connected with a water inlet end pipeline of the water pump; the water level inductor is arranged at the bottom of the water tank, electrically connected with the control module and used for inducting water level in the water tank; the water outlet end of the water pump is connected with an external water supply pipeline; the pressure inductor is arranged at the water outlet end of the water pump, electrically connected with the control module and used for inducting water pressure of the water outlet end of the water pump; the water pump is electrically connected with the control module. The water supply system based on water level induction and pressure induction is simple in structure and convenient to use; it is ensured that water supply water pressure is sufficient and the phenomenon that water can not be pumped is avoided; the water tank automatically injects water, and bacteria are prevented from breeding.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a water supply system based on water level sensing and pressure sensing. Background technique [0002] The so-called secondary water supply usually refers to the form in which units or individuals store and pressurize urban public water supply or self-built water supply, and then supply it to users or for their own use through pipelines. Therefore, secondary water supply is the only choice for high-rise water supply. Way. Whether the secondary water supply facilities are built in accordance with the regulations, the quality of the design and construction is directly related to the water quality, water pressure and water supply safety of the secondary water supply, and is closely related to the normal and stable life of the people. [0003] In the existing water supply system, the phenomenon that the water flow rate is too slow when the water is discharged from the high-rise ofte...
