Non negative pressure water supply equipment for residents' daily life

Description :

Non negative pressure water supply equipment Non negative pressure water supply equipment can achieve simulated artificial intelligence control and has multiple safety protection measures, such as overcurrent, undervoltage, and phase error protection. It is particularly suitable in situations where the water supply pressure is insufficient, which hinders the safety of water supply. With the continuous development of social economy, people's requirements for quality of life and environmental awareness are increasing, especially for drinking water quality. The continuous acceleration of urban construction has led to insufficient local water supply pressure in the secondary water supply network, and the frequency of use of some community pressure pumps is relatively low. Due to the fact that the variable frequency non negative pressure equipment is in a sealed state during use, it ensures the overall cleanliness of the system. In addition, the equipment's own water pipe network and water pump suction port play a role in boosting and stabilizing flow, while cooperating with vacuum suppressors to suppress the formation of vacuum in the pipe network. The vacuum suppressor has a negative pressure automatic elimination function. When the water supply of the municipal pipeline network is less than the required water output of the user, the anti negative pressure device in the equipment includes a vacuum suppressor and a steady flow compensator, which fully utilizes the pressure of the municipal pipeline network without generating negative pressure, ensuring water safety. The composition and principle of the non negative pressure water supply system are mainly composed of a variable frequency speed regulating water pump group, a steady flow compensator, a vacuum suppressor, and a pressure device. The anti negative pressure device in the pressure equipment automatically opens to enter clean air and prevent negative pressure from affecting the municipal pipeline network. When the municipal water supply network returns to normal, the equipment can discharge air through the anti negative pressure device and automatically shut down. The steady flow compensator works under positive pressure, and the equipment operates normally in the water supply network and pump suction port, achieving the purpose of boosting and stabilizing flow, while cooperating with the vacuum suppressor.

Non negative pressure water supply equipment The cost of non negative pressure water supply equipment is very low, which is also an important aspect for the water supply department in terms of operating costs. The article conducts research and analysis on the application of non negative pressure water supply technology in the field of secondary water supply for reference. Due to the fact that variable frequency non negative pressure equipment is in a sealed state during use, the overall cleanliness of the system is ensured, and the equipment itself hinders the safety of water supply. With the continuous development of social economy, people's requirements for quality of life and environmental awareness are increasing, especially for drinking water quality. The continuous acceleration of urban construction has led to insufficient local water supply pressure in the secondary water supply network, and the frequency of use of some community pressure pumps is relatively low. Discussion on the application of non negative pressure water supply technology in the field of secondary water supply (original manuscript). Due to the fact that variable frequency non negative pressure equipment is in a sealed state during use, the overall cleanliness of the system is ensured, and the cost of equipment consumption is very low. This is also an aspect that the water supply department attaches great importance to. During operation, only a smaller type of booster pump is needed, and multiple booster pumps often run simultaneously, which can greatly reduce the consumption of electricity. Due to the lack of filtering devices during peak water use periods, it can effectively filter bacteria. The selection of materials for variable frequency non negative pressure equipment is also quite strict. Stainless steel materials must be used to prevent algae like plants from appearing inside the pipeline. The grade of stainless steel materials is also specified, and the limit of the pressure value of the pipeline network is lower than the user's required pressure. The microcomputer adjusts the speed of the water pump to increase. When the user's required pressure is reached, the water pump runs at a constant speed and supplies water at a constant pressure. If the water supply pressure of the municipal pipeline network is higher than the pressure required by the user, the water pump will stop running and use the municipal pressure.
