1、 Overview of complete frequency conversion water supply equipment products
To solve the negative pressure problem caused by the direct connection of water pumps to the tap water network in traditional water supply systems, our company has innovatively developed a new generation of Zhongying series non negative pressure variable frequency water supply equipment (pipe network regulation and boosting equipment). This product not only solves the problem of secondary pollution in underground water tanks, but can also be matched with purified water equipment and directly used as a booster device for drinking water. It can be used in any water supply system that requires pipeline boosting. This series of products has obtained multiple utility model patents.
The complete set of variable frequency water supply equipment is a new type of pressurized water supply equipment that has emerged in recent years. It achieves constant pressure water supply through microcomputer controlled variable frequency speed regulation. Firstly, set the working pressure of the water point according to the actual situation, and constantly monitor the pressure of the municipal pipeline network. When the pressure is lower than the user's required pressure, the microcomputer automatically controls the sub frequency converter to start, adjusts the speed of the water pump to increase until the pipeline pressure rises to the user's required pressure, and controls the water pump to operate at a constant speed for constant pressure water supply. When the water consumption increases, the speed increases, and when the water consumption decreases, the speed decreases, ensuring a constant water pressure for the user at all times.
The complete set of variable frequency water supply equipment is the sixth generation product upgraded by Zhongying Water Supply Company on the basis of variable voltage water supply equipment. This device adopts a fully enclosed design and can be directly connected to the municipal water supply network. It uses a variable frequency automatic control system to control the variable frequency pump through a vacuum controller and a steady flow regulating tank to protect the municipal network from negative pressure and automatically pressurize the user's pipeline network for variable frequency water supply. At the same time, it also saves a lot of investment in water supply facilities for users, and can supplement as much as the pressure is similar during use, greatly saving energy consumption. The water quality has no secondary pollution, and users can use hygienic domestic water. This device is currently a new type of secondary water supply equipment.
