Abstract: In order to response the states appeal of energy saving and consumption reducing, a large chemical plant has reformed the constant pressure water supply. Through analyzing the energy consumption disadvantages of original water supply systems of that chemical plant, a kind of new constant pressure water supply system was introduced based on both PLC and frequency changer, including the system structure, functions, system software design, and energy-saving principle and benefit. The control system has been applied successfully which can ensure the constant pressure of water-supply and the prominent effect of energy-saving.
Key words: frequency control of motor speed; programmable logic controller(PLC); constant pressure water supply; energy-saving
