Non negative pressure water supply equipment, secondary constant pressure variable frequency water supply equipment

Description :

Non negative pressure water supply equipment The working principle of the non negative pressure water supply equipment adopts microcomputer control technology, which automatically adjusts the frequency conversion 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 non negative pressure water supply 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 and the limit of flow are also clearly defined.
