Tank-type pipe network pressure-superposed water supply equipment with compensation pump and small-flow pump

Abstract

The invention discloses tank-type pipe network pressure-superposed water supply equipment with a compensation pump and a small-flow pump. The tank-type pipe network pressure-superposed water supply equipment mainly comprises a steady-flow compensation tank, a negative-pressure eliminator, a flow control valve, the compensation pump, the small-flow pump, main pumps, a flow detection device and a control cabinet, wherein the steady-flow compensation tank is in a dual-cavity horizontal structure consisting of both a water storage cavity and a steady-flow cavity; a water outlet I is formed in the bottom of the water storage cavity and communicated with a water distribution pipe through a compensation pipe on which the compensation pump is mounted; a small-flow branch pipe is arranged on a water distribution manifold to be connected with a by-pass pipe II; and the small-flow pump is mounted on the small-flow branch pipe. The tank-type pipe network pressure-superposed water supply equipment has the benefits that the advantages of small occupied land, sanitary water supply, energy saving, high efficiency, complete functions, good using effect and the like are achieved; a flow control valve is mounted to limit the pressure drop of a tap water inlet pipe and guarantee no-negative-pressure pipe network pressure-superposed water supply; and the water storage cavity of the steady-flow compensation tank can perform differential compensation and adjustment on tap water inflow deficiency, so that the adjustment volume is increased and the water supply security is improved.

Description

technical field [0001] The invention relates to the technical field of secondary water supply, in particular to a tank-type pipe network superimposed water supply equipment provided with a compensation pump and a small flow pump. Background technique [0002] The pipe network superimposed water supply equipment can be directly connected in series with the urban tap water pipe network for water supply, eliminating the need to install pools and water tanks for traditional water supply, so it has the advantages of less land occupation, less investment, convenient management and maintenance, energy saving and sanitation, and has been widely used at present. Used in secondary water supply fields such as residences, offices, hotels, etc. However, the pipe network superimposed water supply equipment has the disadvantages of small adjusted water capacity, low water supply safety, and low flow operation without energy saving, which limits its popularization and application in some se...
