Non negative pressure variable frequency water supply manufacturer

Description :

Non negative pressure water supply equipmentMain functions:

　　1. Fully automatic completion of the entire operation process of soft start, frequency conversion to power frequency operation, and stop for multiple water pump units.

　　2. According to changes in water usage, it becomes the start and stop of multiple pump units.

　　3. The LED display with pressure setting value and actual pressure value is the main function.

　　4. There is LED frequency indication, frequency conversion abnormal indication, and motor fault condition display.

　　5. Main protection functions: It has main functions such as undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, and burn prevention.

　　Classification of non negative pressure water supply equipment:

　　There are mainly two types of non negative pressure water supply equipment used in the market: steady flow tank type and regulating water tank type;

　　1. Stable flow tank type: The tank type non negative pressure water supply equipment is equipped with a pressure sealing tank in front of the water pump, and a stable flow compensator (also known as a "vacuum eliminator") is added inside or outside the tank. The water pump absorbs water through the stable flow tank, pressurizes it, and supplies it to the user. With the regulating effect of the stable flow compensator, the impact on the public water supply network is reduced. This method has no reserve water supply, and when the urban public water supply network is shut down, it is prone to water interruption;

　　2. Regulating water tank type: This method is equipped with an unpressurized regulating water tank, which is internally equipped with a steady flow compensator. Through an electronic control device, the water in the regulating water tank is circulated at least twice a day to ensure that the water quality remains unchanged. When the water volume and pressure conditions of the municipal pipeline network can meet the requirements of non negative pressure water supply, water can be directly taken from the municipal pipeline network; Otherwise, take water from the regulating water tank. This method has a certain reserve water capacity and can be used in areas with unstable water supply networks, but due to the presence of water tanks and maintenance manholes, regular cleaning and disinfection must still be carried out according to regulations
