Variable-frequency constant-pressure water supply assembly

Abstract

The invention relates to the technical field of water supply, and discloses a variable-frequency constant-pressure water supply assembly. The variable-frequency constant-pressure water supply assemblycomprises an electric control cabinet, a water pump set, an air pressure tank, a water supply pipe, a water collection mechanism, a telescopic mechanism and a water storage tank; an electric controlsystem and an ABB frequency converter are fixedly installed inside the electric control cabinet; the water pump set, the air pressure tank and the water supply pipe are arranged on the left side of the electric control cabinet; the water inlet end of the water supply pipe is fixedly connected and communicated with the water storage tank; a filtering mechanism is fixedly installed inside the waterstorage tank, and the filtering mechanism adopts a reverse permeable membrane filtering mechanism; the water collection mechanism is fixedly arranged on the left side of the water storage tank; the telescopic mechanism is fixedly arranged on the water collection mechanism; through the arrangement of a corrugated pipe, a bottom plate can sink through the weight change after water enters the bottomplate, so that a water collecting space is enlarged, the deformation range can be freely changed according to the strength of the external water pressure, the effect of automatically balancing internal pressure and external pressure is achieved, and compared with arrangement of an existing water collection mechanism, the variable-frequency constant-pressure water supply assembly has the advantageof avoiding damage to the water collection mechanism caused by excessive increase of external water pressure.

Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a variable frequency constant pressure water supply assembly. Background technique [0002] The variable frequency constant pressure water supply equipment is a new type of energy-saving water supply equipment. The existing variable frequency constant pressure water supply equipment is also widely used on medium and large ships. [0003] The existing patent numbers CN104060649B and CN209873945U both propose a variable frequency constant pressure water supply assembly, which usually extends the pipeline directly into the water when supplying water. Directly acting on the pipeline, and the flow of water relative to the pipeline will increase the effect of the pressure. After the ship runs for a long time, the pipeline is prone to breakage due to the excessive pressure difference between the inside and outside of the pipeline. Therefore, a variable frequency constant pressure...

Problems solved by technology

[0003] The existing patent numbers CN104060649B and CN209873945U both propose variable frequency constant pressure water supply components. When supplying water, the pipeline is usually extended directly into the water. However, during the movement of the ship, as the position changes, the pressure on the water surface will increase and decrease. It acts directly on the pipeline, and the water flow is flowing relative to the pipeline, which will increase the pressure effect. After the ship has been running for a long time, the pipeline is likely to be broken due to the excessive pressure difference between the inside and outside of the pipeline, etc.
