摘要
为确保压风机冷却装置不因缺水而失效 ,必须为每台压风机装备断水保护。分析了普通电接点压力表组成的断水保护原理及不足 。
Be sure to compressor not loss efficacy for disconnected water,disconnected water protection mechanism must be equipped.The paper analyses air compressor's protection of disconnected water principle based on common manomeler which presents defects,and concluded that the successful application of PLC in air compressor's protection of disconnected water.
