Frequency conversion constant pressure water supply system, Honghuayu technology constant pressure water supply system
Constant pressure water supply system
The water supply system is an indispensable part of the national production and life. The traditional water supply method covers a large area, the water quality is easy to be polluted, and the infrastructure investment is high. The main disadvantage is that the water pressure cannot be kept constant, and some equipment cannot work normally. Frequency conversion speed regulation technology is a new type of mature AC motor stepless speed regulation technology. It is widely used in the field of speed control with its unique and excellent control performance, especially in the water supply industry. Due to the special needs of safe production and water supply quality, there are strict requirements for constant pressure water supply pressure, so the frequency conversion speed control technology has been applied more deeply.
The actual pressure of the pipe network is compared with the given pressure after feedback. When the pipe network pressure is insufficient, the frequency converter increases the output frequency, the water pump speed increases, and the water supply increases, forcing the pipe network pressure to rise. On the contrary, the water pump speed is slowed down, the water supply is reduced, the pipe network pressure is reduced, and the constant pressure water supply is maintained.
Constant pressure water supply can complete the following functions in the pump station water supply:
(1) Maintain a constant water pressure
(2) The control system can be operated manually/automatically
(3) Multiple pumps automatically switch operation
(4) System sleep and wake up, when the outside world stops using water, the system is in a sleep state, and automatically wakes up when there is demand for water.
(5) Adjust the PID parameters online;
(6) Pump group and line protection detection alarm, signal display, etc.
