A frequency conversion constant pressure water supply component

Abstract

The invention relates to the technical field of water supply, and discloses a variable frequency constant pressure water supply assembly, including an electric control cabinet, a water pump group, a pressure tank, a water supply pipe, a water collection mechanism, a telescopic mechanism and a water storage tank, and the inside of the electric control cabinet is fixedly installed with The electric control system, ABB frequency converter, water pump unit, air pressure tank and water supply pipe are all 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, and a filter mechanism is fixedly installed inside the water storage tank. The filter mechanism adopts the reverse osmosis membrane filter mechanism. The water collection mechanism is fixedly installed on the left side of the water storage tank. It sinks, thereby expanding the water collection space, and its deformation range can be freely changed according to the strength of the external water pressure, which has the effect of automatically balancing the internal and external pressure. Compared with the existing water collection mechanism, it can avoid external water pressure Added the benefit of being too large to cause damage to the water collection mechanism.

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] Frequency conversion constant pressure water supply equipment is a new type of energy-saving water supply equipment. The frequency conversion constant pressure water supply equipment is a high-tech energy-saving water supply device with electromechanical integration, which uses the most advanced microcomputer control technology and combines frequency conversion speed regulator and motor water pump. The existing frequency conversion constant pressure water supply equipment is also widely used on medium and large ships. [0003] Existing patent numbers CN104060649B and CN209873945U both proposed 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 pos...

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.
