Principle of constant pressure water supply of remote pressure gauge:
1. Use variable frequency motor to realize constant pressure water supply. The variable frequency constant pressure water supply system uses the water pressure of the pipe network (i.e., the reading of the remote pressure gauge) as the setting parameter, and controls the output frequency of the frequency converter through a microcomputer to automatically adjust the speed of the water pump motor to achieve closed-loop regulation (PID) of the water pressure of the pipe network. , so that the water supply system automatically stabilizes at the set pressure value: that is, when the water consumption increases, the frequency increases, the water pump speed increases, and the water supply volume increases accordingly; when the water consumption decreases, the frequency decreases, the water pump speed slows down, and the water supply volume also increases. The water supply efficiency is reduced accordingly, thus ensuring the water supply efficiency users' requirements for water pressure and water volume, and at the same time achieving the purpose of improving water supply quality and water supply efficiency, "how much water is used, how much water is supplied"; using this equipment does not require the construction of a high-level water tank, The water tower has no secondary pollution in water quality and is an ideal water supply equipment for modern buildings.
2. Use regulating valves to achieve constant pressure water supply. The constant pressure water supply system uses the water pressure of the pipe network (i.e., the reading of the remote pressure gauge) as the setting parameter, and controls the opening of the water pump outlet valve through a microcomputer to realize closed-loop adjustment (PID) of the water pressure of the pipe network, so that the water supply system automatically stabilizes at The set pressure value: that is, when the water consumption increases, the valve opening increases and the water supply volume increases accordingly; when the water consumption decreases, the valve opening decreases and the water supply volume also decreases accordingly, thus ensuring the water supply efficiency for users. The requirements for water pressure and water volume simultaneously achieve the purpose of improving water supply quality and water supply efficiency, "how much water is used, how much water is supplied."
