Description :

Non negative pressure variable frequency water supply equipmentIt is a complete set of water supply equipment that is directly connected to the municipal pipeline network without affecting it. On the basis of ZBH variable frequency constant pressure, this device superimposes the pressure of the municipal pipeline network and the pressure of the lifting water pump, making domestic water supply more energy-efficient and environmentally friendly. It is an ideal replacement product for traditional secondary water supply. The equipment consists of a frequency conversion control cabinet, a non negative pressure device, an automation control system and remote monitoring system, a water pump unit, a voltage regulator compensator, a negative pressure eliminator, pressure sensors, valves, instruments, and piping systems. Variable frequency water supply equipment is widely used for production, living, and office water in enterprises, institutions, residential areas, and rural areas. There are 20-2000 water supply households. The daily water supply is between 20-50000m3, and the water supply height reaches 150 meters, which is a 50 story building.

　　The working principle of the variable frequency water supply equipment adopts microcomputer control technology, which automatically adjusts the variable frequency speed of the water pump group or increases or decreases the number of water pumps according to the user's water consumption to achieve constant pressure water supply. Firstly, set a constant working pressure based on the user's water supply requirements. If only a smaller type of booster pump is needed in the municipal process, and multiple booster pumps are often running simultaneously, it can greatly reduce the consumption of electricity. Due to the different peak periods of water use, the municipal pipeline network has peak and low peaks during water supply. In the low peak period, there is a filtering device that can effectively filter bacteria. The selection of materials for variable frequency non negative pressure equipment is also quite strict, and stainless steel materials must be used to prevent algae like plants from appearing inside the pipeline. The grade of stainless steel materials is also clearly defined, and the limited protection zone generally suffers from low water supply pressure during peak water use periods, causing difficulties for users to use water. Traditional water supply systems do not have remote monitoring systems, and pump rooms must have on duty operators. The non negative pressure water supply system can achieve monitoring along the way, reach the pump room, and save manual labor. The application of non negative pressure water supply technology in the field of secondary water supply is discussed (original manuscript). The water pipe network and pump suction port play a role in boosting and stabilizing the flow, while cooperating with vacuum suppressors to suppress the formation of vacuum in the pipeline network. The vacuum suppressor has a negative pressure automatic elimination function. When the water supply of the municipal pipeline is less than the required water output of the user, the anti negative pressure device in the equipment also has a filtering device, which can effectively filter bacteria. The selection of materials for variable frequency non negative pressure equipment is also quite strict, and stainless steel materials must be used to prevent algae like plants from appearing inside the pipeline. The grade and flow limit of stainless steel materials are also clearly defined.
