Non-negative pressure variable frequency water supply control cabinet can complete equipment automation and process automation control. Complete network functions have the characteristics of stable functions, scalability, strong anti-interference ability, and are the center and soul of modern industry. Users can design PLC control cabinets, frequency converter cabinets, , etc. according to their needs, and can match them with the human-computer interface touch screen to achieve the purpose of convenient operation.

Typical applications include constant pressure water supply, air compressor , fans and pumps, central air conditioners, port machinery, machine tools, boilers, paper making machinery, food machinery , etc. Non-negative pressure variable frequency water supply control cabinet has functions such as overload, short circuit, and maintenance of phase-loss . It operates stably and has complete functions. It can be combined according to the actual control size. It can not only complete the automatic control of a single cabinet, but also complete a distributed control system (DSC) composed of multiple cabinets through industrial Ethernet or industrial fieldbus network. Can be adapted to industrial automatic control occasions of various sizes. Widely used in power, metallurgy, chemical industry, papermaking, environmental sewage treatment and other industries.

Negative pressure variable frequency supply equipment is a water supply method that makes full use of the original pressure of municipal pipeline water sources to form continuous relay pressurization, and achieves energy-saving, efficient, and pollution-free water quality. It is the development and extension of variable frequency constant voltage water supply equipment.

The working principle is:

takes the water pressure of the pipeline network as the setting parameter, and automatically adjusts the water pump by controlling the output power of the inverter to realize the adjustment of the water pressure, so that the water supply system can automatically achieve constant and stable settings.

When the tap water pressure meets the water demand, that is, when the pipeline pressure is higher than the set pressure, the output frequency is reduced, the pump speed is reduced, and the water output is reduced. When the water pressure cannot be met during the peak water use period, that is, when it is lower than the set pressure, the output frequency is increased, the pump speed is increased, and the water output is increased. When one pump cannot meet the water demand, other pumps will be put into use automatically and automatically adjusted according to the water consumption to achieve the purpose of constant pressure water supply. The equipment adjusts the water supply efficiency according to the water consumption to achieve efficient water supply.

has many advantages. It has no water storage tanks and water storage tanks, and it is fully enclosed and operates without secondary pollution;

does not need to build a water storage area, and does not require excessive maintenance, disinfection, etc., which can save construction costs and post-maintenance and cleaning costs;

has small facilities, takes up less land, and is simple and convenient to install; it is suitable for water supply in small communities.
