这种方法比较简单,可以不与泵体接触。但由于噪声法受周闱环境噪声的影响较大,当显示其强度最高时。一般水泵皇冠即时比分气蚀已达到非常强烈的阶段,这时入耳已能通过强烈的气蚀爆裂声判别气蚀工况。因此,泵体噪声法不太适合现场监测气蚀的发生。

对减轻泵的气蚀破坏有应用实例,有时需要几种方法同时采用。综上所述,离心泵的安装过程中,为了尽量避免气蚀现象的产生,应遵循几点原则:水泵安装高度必须低于泵的允许吸上高度;吸入管路应短而直,管件尽量少,吸入管的直径不应小于吸入口的直径;变径处不能有气体积存。总之,在管道离心泵皇冠即时比分的运转过程中,要注意有无不正常的噪音,观察压力表等是否正常,同时还应定期检查轴承、轴封发热情况,并要注意润滑及轴封处是否有不正常的渗液情况。
