你的意思是罗茨风机效率下降,应该每小时抽的介质没有达到规定量,造成介质憋在进口这里。

抽的是空气,到处都是,哪里有什么憋不憋在进口的说法

这个正压还是负压是怎么测量出来的,进出风管连接是不是漏风呀
Reply #82018-10-29
脱开管道!开机,进口是负压!出口是正压,明显有风!

哈哈!不要武断哦!分子变轻也会引起类似情况,我们都是猜测,期待楼主给出实际查出的原因!

罗茨风机属于容积式风机,靠的就是转子不断挤压变化空间里的气体介质来实现输送目的的:一方面确保能够升高介质压力,一方面要能够维持出入口间的压差。 一台成型的风机基本参数(流量、压力、转速、介质)都是确定的,只有同时满足上述两个方面条件才能保证风机符合工况条件运行,否则就如楼主叙述的类似问题(只是一种情况而已)出现。 【按楼主叙述:风机空载试运正常,只能说明风机不加负荷的条件下能够运行,验证了机械性能没问题(也是空载试运的目的);风机加负荷运行不正常,验证了工艺性能有问题】 那么,大家看看哪些方面出问题了?

直接打电话给供应商,这是最快的处理方法

现在还不清楚!在查!如果不行的话!就要解体了
