Box and pump integrated variable-frequency pressure-superposed water supply equipment

Abstract

The invention discloses box and pump integrated variable-frequency pressure-superposed water supply equipment. The box and pump integrated variable-frequency pressure-superposed water supply equipment comprises a furnace body and a flow stabilizing tank, wherein the top of the flow stabilizing tank communicates with the close end of a municipal water supply network. In conclusion, according to the box and pump integrated variable-frequency pressure-superposed water supply equipment, a first flow dividing branch pipe, a second backflow pollution preventing device, a turbulent flow descaling assembly, a pressure control assembly and other structures are matched with one another, so that the condition that the stability of a water pump unit is seriously influenced because the load intensity of the water pump unit is increased due to large water supply pressure of a variable-frequency pressure-superposed water supply system and high water pressure in the flow stabilizing tank can be avoided, part of sediments are prevented from being attached to the wall of the flow stabilizing tank due to standing of water at night and in other time periods with low water demand, the water supply quality is not influenced, the body health of drinkers is good, the practicability of the variable-frequency pressure-superposed water supply system can be increased, the starting frequency of the water pump unit in unit time is reduced, and the water pump unit can be preferably protected.

Description

technical field [0001] The invention relates to the technical field of secondary water supply equipment, in particular to a tank-pump integrated frequency conversion superimposed pressure water supply equipment. Background technique [0002] The frequency conversion superimposed water supply equipment is a secondary pressurized water supply equipment that the pressurized water supply unit is directly connected to the water supply pipe network. It is generally used in municipal water supply pipe networks or pressurized water supply pipe networks. According to the characteristics of different occasions, the superimposed pressure water supply equipment can be divided into tank type, box type, high-level livestock adjustment type, and pump-in-pipe type. , Vacuum suppressor, steady flow tank, pressure sensor, water pump unit, electric control valve, high temperature water phase and supporting automatic control cabinet, etc. Compared with the previous water supply equipment, it ha...

AI Technical Summary

Problems solved by technology

[0003] In the process of using frequency conversion superimposed water supply equipment for water supply, excessive water pressure in the municipal water supply pipe network is prone to occur during low water consumption periods, which will not only cause waste of pressure, but also cause frequency conversion superimposed water supply systems due to excessive water pressure. The increase of the load will seriously affect the stability of the fre
