密封面都是硬质合金的?压量过大了比压大时会有声音。石墨没遇到过有刺耳声音

密封压盖内有气未排除造成的,在冲洗系统冲入缓冲液的时候先充一点,估计可以把密封压盖内的那部分充满后盘车,排气后再充到缓冲罐指定液位

介质温度高,或容易气化,机泵运行时存在气蚀,抽空。或者密封压缩量大,温度较高,动静环密封面的液膜气化后动静环面磨檫产生声音

运行正常!若是机械密封动静环摩擦不是瞬间就烧坏了吗?

就像密封环精研磨后进行抛光,抛光时也是会出现这样吱吱的声音,密封面光节度高,而不会损坏密封,液膜气化后会有凉的介质来补充,给密封环表面降温,这个动静磨檫是很轻微的,并不是密封面全部,可能只是一个点或者很小的一个区域。

声音很空洞,具体位置听不出来那里发出的,但在机械密封附近内部

降低密封冲洗液或隔离液得我温度试试

PLAN21,没有冷却的。

有高点肯定会泄漏,但是机械密封运行良好!

那个点不是高点,时介质气化的一个点或者很小的区域
