Technical characteristics of non negative pressure variable frequency water supply equipment

Description :

Non negative pressure variable frequency water supply equipmentTechnical feature 1: More energy-efficient: The non negative pressure water supply system can fully utilize the pressure of the municipal pipeline network to increase pressure, and compensate for the difference; 2. Non negative pressure water supply system is more environmentally friendly: the structure of the pressurized water tank adopts a fully enclosed design, and the ventilation hole adopts a reciprocating suction and exhaust filtration device, effectively filtering dust and debris. The bottom of the water tank is equipped with a water intake device, which effectively increases the water intake area, ensures the freshness of the water quality, and solves the problems of water retention layer and stagnant water layer in the water tank; 3. The unique configuration of the non negative pressure water supply system: the water tank is equipped with an intelligent boosting device to ensure stable pressure in the user's pipeline network after the water pump is switched, and the water pump operates in the high-efficiency zone. A time controller is added to the control system to cycle the water source of the water tank at regular intervals, ensuring fresh water quality in the water tank; 4. The safety of the non negative pressure water supply system is high: when the municipal pipeline network stops water supply or the peak water consumption of users lasts for a long time, the pressurized water tank ensures water supply, greatly improving the reliability of water use; 5. Non negative pressure water supply system control * *: Establish a remote monitoring system to dynamically monitor equipment operation at any time; 6. The non negative pressure water supply system has a wide range of applications: it is suitable for all areas that require secondary pressurized water supply. 1. The variable frequency non negative pressure water supply equipment is affordable, occupies a small area, and does not require the construction of water tanks or reservoirs. It is directly connected to the tap water network for pressurized water supply, fully utilizing the pressure of the tap water network for one-time water supply. 2. The quality of water supply has been improved, and pure tap water is directly supplied to users after being pressurized by equipment, without negative pressure tank anti-corrosion treatment and sealed connection. 3. Easy to install, no negative pressure variable frequency water supply equipment is provided as a complete set to users, and only the inlet and outlet pipes need to be connected on site, with a short construction period. 4. The improvement of water supply quality has solved the problem of secondary pollution. 5. A power outage will not affect the water supply because the equipment has a public water supply pipeline directly connected to the user's pipeline network. Although the booster pump stops working during a power outage, the primary water supply pressure of the water plant can still maintain the water supply. 6. The water supply system is hygienic and pollution-free, with a fully sealed structure from the tap water network to the user's faucet. The fully automatic water softener prevents pollutants from entering the system; The water body does not come into direct contact with the air, and the overcurrent components are made of food grade stainless steel, which does not pollute the water quality.

　　The main application places of non negative pressure water supply equipment are high-rise buildings, residential communities, villas, and other residential areas for domestic water use. 2. Daily water supply for enterprises, institutions, hotels, office buildings, department stores, large saunas, hospitals, schools, sports halls, golf courses, airports and other places. 3. Production water for manufacturing, washing equipment, food industry, factories, and mines. 4. The already built water tank can be supplied with non negative pressure water supply equipment and shared with the water tank to further save energy; 5. Transforming the existing pneumatic water supply equipment can fully utilize the existing pneumatic tanks; 6. Various circulation systems, intermediate booster pump stations in water plants; 7. Other: Renovation of old water tanks and other forms of water supply;

　　The working principle of the non negative pressure 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.
