Box-type pressure-superposed water supply equipment

Abstract

The invention relates to box-type pressure-superposed water supply equipment, which comprises a variable frequency controller, a built-in sterilizer water tank, a steady flow compensating tank, a No.1 variable frequency pump and a No.2 variable frequency pump, wherein the steady flow compensating tank comprises a water inlet and a water outlet; a supporting device is arranged at the bottom of the steady flow compensating tank; a vacuum suppressor is arranged on the steady flow compensating tank; the water outlet of the steady flow compensating tank is connected to the water inlet ends of the No.1 variable frequency pump and the No.2 variable frequency pump by virtue of a water sucking pipeline; the water outlet ends of the No.1 variable frequency pump and the No.2 variable frequency pump are connected to a user pipe network by virtue of a water supply pipeline and a water softening processing device; the water inlet of the steady flow compensating tank is connected to a water outlet of a supercharger and a municipal water supply pipeline by virtue of a water inlet pipe; the water inlet of the supercharger is connected to the water tank; the water tank is connected to the municipal water supply pipeline; and a pressure maintaining tank is arranged on the water supply pipeline. According to the box-type pressure-superposed water supply equipment provided by the invention, water supply pressure can be adjusted through the effective utilization of the supercharger and water, after being disinfected and softened, can be supplied to users, and automatic switching control can be achieved.

Description

technical field [0001] The invention belongs to the technical field of secondary water supply equipment, and in particular relates to a box-type laminated water supply equipment. Background technique [0002] At present, when the general water supply equipment is directly connected to the water pipe network, there will be negative effects, because the flow rate of the water pump is often greater than the water flow of the water pipe, which will cause a drop in the pressure of the pipe network and affect the water use of surrounding users. In order to solve the irrationality of this water supply scheme, the traditional water supply method needs to build a water source tank and a roof tank at the inlet of the water pump. This traditional water supply scheme has the following three problems: [0003] First, both the water pump water tank and the roof water tank are prone to pollution problems, because the design of the pools has overflow outlets, and the water tanks for domesti...

AI Technical Summary

Problems solved by technology

[0003] First, both the pump water source water tank and the roof water tank are prone to pollution problems, because the design of the pools has overflow outlets, and the water tanks for domestic use must be cleaned regularly to avoid water quality deterioration, resulting in waste of drinking water

[0004] Second, the construction cost of the roof water tank is relatively high, and with the development of the city, the roof water tank is also ugly

[0005] Third, the tap water in the municipal pipe network must first be put into the water source tank and then pumped to the roof tank. In this way, the pressure energy of the tap water is wasted

[0007] At present, the main secondary pressurized water supply equipment on the market is non-negative pressure water supply equipment, which can be selected according to the specific supply and demand conditions of the project. Usually, it is equipped with a steady flow compensation tank, and the steady flow compensation tank is equipped with a vacuum suppression device. However, when the current secondary water supply equipment or system uses the water tank to supply water, the pressure of the water flowing out of the water tank cannot meet the requirements for use, and the water pressure entering the steady flow compensation tank cannot be effectively controlled in real time, and the current tap water is relatively hard. If it is directly supplied to users, it cannot meet the actual water needs of users
