摘要
介绍一种以PLC作为总控制部件,采用变频器控制中央空调冷冻水循环泵,构成恒压循环供水;变频调速循环供水,以及用PLC控制一台软起动器分别起动4台井水泵的控制系统。从而实现节能的目的,提高系统的可靠性,确保设备的安全运行。
A PLC as to the total control of parts,a central air-conditioning control inverter pump chilled water cycle,a constant pressure water cycle;VVVF cycle of water,and with PLC control a soft start for each start 4 pump cousntrol system.Th achieving the purpose of energy conservation,improve the reliability of the system to ensure the safe operation of equipment.
