Energy-saving type network pressure-superposition water supply device for waterworks

Abstract

The present invention relates to the technical field of water supply equipment, and in particular, discloses an energy-saving type network pressure-superposition water supply device for waterworks. The device includes a steady flow tank, a variable speed pump, a fixed frequency pump, a PLC controller and a variable speed pump control system. A current transforming plate is arranged inside the steady flow tank for forming up and down baffling loops. The steady flow tank is fixedly connected with a water inlet flange and a water outlet flange respectively. The water inlet flange is fixedly connected with the water supply header pipe. The water outlet flange is fixedly connected with a first water supply pipe. The first water supply pipe communicates with the variable speed pump. The variablespeed pump communicates with a second water supply pipe. The second water supply pipe is provided with a pressure sensor and a flow sensor. The device has the following beneficial effects: the devicetransforms the original mechanical network pressure-superposition water supply into electronic network pressure-superposition water supply, makes full use of a flow compensation function of the steady flow tank, realizes good effect of reducing peak and filling valley on large-scale municipal water supply, and optimizes and transforms the steady flow tank to realize automatic water update in thesteady flow tank and insure water not to deteriorate.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to an energy-saving pipe network superimposed water supply device for a waterworks. Background technique [0002] Pipe network superimposed water supply equipment is a pressurized water supply unit that is directly connected to the municipal water supply pipe network, and is connected in series to superimpose water supply on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the set protection pressure. water supply equipment. The core of the pipe network superimposed water supply equipment 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, and safety without affecting the water use of nearby users. Smooth, continuous water...

AI Technical Summary

Problems solved by technology

[0005] At present, because the electronic pipe network superimposed water supply equipment does not use the steady flow tank, after the mechanical pipe network superimposed water supply equipment of the existing waterworks is transformed into the electronic pipe network superimposed water supply equipment, there is a problem that the steady flow tank is discarded
