Plant Water Supply System Of Frequency Conversion Constant Pressure Technology Research And Application

With the rapid development of social market economy, the first people to water quality and the reliability of water supply system constantly improve; Secondly the current energy shortage, the use of advanced control technology, automation technology and communication technology, the design in the field of high performance, high energy saving, can adapt to different variable frequency constant pressure water supply system become inevitable trend.The paper analyses the principle of variable frequency constant pressure water supply and the structure of the system, a variety of control scheme is put forward, through comparison and study, this paper adopts PLC and frequency converter to realize constant pressure water supply and data transmission, and then use PID constant pressure control of system design. Finally, the detailed introduction to the system hardware design. The paper design and implementation based on the MCGS configuration software system for data transmission circuit of the remote network monitoring system. Detailed expounds the overall design of the system and the realization of the software can, and the system reliability measures added.The paper’s variable frequency constant pressure water supply system has been widely used in water supply system in domestic factory, and get reliable and stable operation and good energy saving effect. Practice shows that the system has high reliability and practicability, greatly improves the quality of the water supply, and saves manpower and material resources, financial resources, has significant economic and social benefits.
