Abstract

The invention discloses a complete constant-voltage frequency conversion water supply system. The system comprises a frequency conversion water pump, a first pipeline is fixedly connected to an outputend of the frequency conversion water pump, a first tee joint is fixedly connected to the end, away from one end of the frequency conversion water pump, of the first pipeline, an output pipeline is fixedly connected to the right end of the first tee joint, a second tee joint sleeves the outer surface of the output pipeline, a pressure gauge is fixedly connected to the upper end of the second teejoint, a fixed frequency water pump is arranged on the upper portion of the frequency conversion water pump, and a second pipeline is fixedly connected to an output end of the fixed frequency water pump. According to the complete constant-voltage frequency conversion water supply system, by arranging a frequency converter, the power supply frequency of the frequency conversion water pump can be adjusted conveniently according to a numerical value displayed on the pressure gauge, and the system is stable in pressure; by arranging a pressure reducing valve, under the action of a stop valve, thewater supply pressure of the system can be effectively adjusted when the frequency converter is damaged, and the water supply pressure of the water supply system can be stable all the time.

Description

technical field [0001] The invention relates to the technical field of water supply systems, in particular to a complete set of constant pressure and frequency conversion water supply systems. Background technique [0002] The water supply system refers to the complex of reservoirs, water pumps, pipelines and other projects that are required to supply different water departments according to certain quality requirements. As far as the function of the water supply system is concerned, the entire water supply system should meet the user's requirements for water quality, water quantity and In addition to the demand for water pressure, low investment, low operating costs, and convenient operation are also required in the entire infrastructure process and production operation. [0003] In regional water supply systems such as residential quarters, hotels, restaurants, etc., due to system configuration problems, water pressure is often unstable, which seriously affects people's qu...
