Water supply control system for pump station of a non-negative pressure water supply device

Abstract

The invention discloses a water supply control system for a pump station of a non-negative pressure water supply device. The water supply control system for the pump station of the non-negative pressure water supply device includes a steady flow compensation tank and a closing mechanism, a first water pipe is opened on one side of the upper end of the steady flow compensation tank, a filter cavityis embedded in the first water pipe, an extraction mechanism is arranged in the filter cavity, a vacuum suppressor is inlaid on the other side of the upper end of the steady flow compensation tank, asecond water pipe is fixed to the lower end of the steady flow compensation tank, a water pump unit is arranged at the other end of the second water pipe, and an electric motor is fixed to the upperend of the water pump unit. According to the water supply control system for the pump station of the non-negative pressure water supply device, through a floating ball and a first sliding block, whenwater enters the steady flow compensation tank, the floating ball at the water inlet end of the steady flow compensation tank rises with the water level in the steady flow compensation tank, a sealingplug is driven by the floating ball to move upward, the sealing plug automatically seals the water inlet port of the steady flow compensation tank, through a support rod and a connecting rod, the floating ball can be fixed to prevent the floating ball from shaking, and the steady flow compensation tank is automatically sealed.

Description

technical field [0001] The invention relates to the technical field of non-negative pressure water supply, in particular to a water supply control system for a pump station of non-negative pressure water supply equipment. Background technique [0002] Non-negative pressure water supply equipment is an ideal energy-saving water supply equipment. It is a secondary water supply equipment that can be directly connected to the tap water pipe network without any side effects on the tap water pipe network. The core of superimposed water supply is how to prevent negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipe network, and achieve safety, reliability, stability, and Continuous water supply. [0003] In the existing non-negative pressure water supply equipment pump station water supply control system, the municipal network water needs to be manually operated when flowing into the ste...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the existing water supply control system of the pump station without negative pressure water supply equipment. The municipal network water needs to be manually operated when it flows into the steady flow compensation tank. The process is cumbersome and troublesome. The working environment of the control system is humid, and the motor is easily damaged by moisture intrusion, which reduces the service life of the motor. The proposed water supply control system for the pumping station of the non-negative pressure water supply equipment
