Energy-saving supercharger for maintaining pump by using residual pressure of municipal water supply network, mounting method and working method

Abstract

The invention discloses an energy-saving supercharger capable of maintaining a pump by utilizing residual pressure of a municipal water supply network, an installation method and a working method, and belongs to the field of secondary water supply superchargers. A pump-maintaining energy-saving supercharger utilizing the residual pressure of a municipal water supply network makes full use of the energy of municipal residual pressure to do work and drive a piston cylinder in the supercharger to two strokes, the upper end area of the piston cylinder is n times that of the lower end area, pressure n times that of the municipal residual pressure is generated in a lower cavity through hydraulic acting of an upper cavity, and pressurized water supply without consuming electric energy is achieved; the working water obtained after excess pressure utilization also uses municipal excess pressure to do work to drive the piston to move reversely, the working water obtained after work doing of the upper cavity is injected into the water tank, and although the pressure of the upper cavity in the second stroke of the piston cylinder is the municipal excess pressure, water stored in the upper cavity is enough to be fed into the non-pressure water tank. The supercharger is particularly suitable for green water supply without power consumption during the small-flow water consumption period at night in buildings and communities.

Description

technical field [0001] The invention belongs to the field of energy-saving supercharging for serving secondary water supply, in particular to an energy-saving supercharger, an installation method and a working method of a pump utilizing residual pressure of a municipal water supply pipe network. Background technique [0002] Due to the rapid development of urban construction, the increase of building density and the increase of water load, the renovation of the municipal water supply network lags behind, resulting in a decrease in the pressure of the municipal pipe network (hereinafter referred to as residual pressure), which cannot meet the direct water supply of old communities. In order to prevent the impact on the municipal pipe network, Water supply companies restrict users from using superimposed water supply, so the secondary water supply of a large number of old residential areas adopts the method of "water tank (pool) + frequency conversion" to regulate storage and b...

AI Technical Summary

Problems solved by technology

When the water from the municipal pipe network is introduced into the water tank, the residual pressure is released in vain and returns to zero, and the residual pressure cannot be used and is wasted
