Box-type pressure-superposed variable-frequency energy-saving water supplying system

Abstract

The invention discloses a box-type pressure-superposed variable-frequency energy-saving water supplying system. The energy-saving water supplying system comprises a water inlet pipe, a water tank, a flow stabilizing tank, a booster pump, pressurizing pumps, an air pressure tank and a water outlet header pipe. The water inlet end of the water inlet pipe is connected with the water outlet end of a municipal pipe. The water outlet end of the water inlet pipe is connected with the water inlet end of the water tank and the water inlet end of the flow stabilizing tank. The water inlet end of the booster pump is connected with the water outlet end of the water tank, and the water outlet end of the booster pump is connected with the water outlet end of the flow stabilizing tank. The pressurizing pumps include the first main pump, the second main pump and the auxiliary pump, wherein the first main pump, the second main pump and the auxiliary pump are connected between the flow stabilizing tank and the water outlet heater pipe in parallel. The air outlet end of the air pressure tank is connected with the air inlet end of the water outlet header pipe through a first butterfly valve. By means of the energy-saving water supplying system, the pressure potential energy of a municipal water source can be sufficiently used, and relaying boosting water supplying can be achieved; when the municipal water pressure and the municipal water amount can not meet the requirements of users, a water supplying mode is automatically switched into a water tank water supplying mode, and twenty-four-hour continuous constant-pressure water supplying to the users can be achieved.

Description

technical field [0001] The application relates to the technical field of secondary water supply, in particular to an energy-saving water supply system with box-type stacking and frequency conversion. Background technique [0002] The so-called secondary water supply usually refers to the form in which units or individuals store and pressurize urban public water supply or self-built water supply, and then supply it to users or for their own use through pipelines. Therefore, secondary water supply is the only choice for high-rise water supply. Way. Whether the secondary water supply facilities are built in accordance with the regulations, the quality of the design and construction is directly related to the water quality, water pressure and water supply safety of the secondary water supply, and is closely related to the normal and stable life of the people. [0003] With the development and progress of social economy, science and technology, the water quality standard of muni...

Problems solved by technology

However, the existing water supply system has the following shortcomings: 1. The design of the water pump system is unreasonable. No matter the change of the overall flow rate of the water supply system, usually only one water pump works, which easily causes the water pump to be overloaded, shortens the service life of the water pump, and increases Second, the water demand is different, the required water supply p
