螺杆泵响声大的原因

螺杆泵响声大的原因有多种,常见的有紧固螺丝松动导致不牢固、发生气蚀、泵内组件有损坏等情况,正常运行下的螺杆泵声浪平稳,若有明显异响则需及时停泵检查,有必要的话可对泵体进行拆卸检查,确保问题排除后再启用。

螺杆泵因结构简单,在实际使用中故障发生率并不高,是可以长时间连续使用,是一种耐用性很高的运输设备,但是若因操作不当或者超过正常使用年限,难免出现问题,及时排除螺杆泵响声大的原因十分重要,可以确保工艺项目的稳定进行,就以往设备使用经验来看,用户可参考以下几种操作方式。

1、螺栓松动。单螺杆泵在长时间的使用中螺栓逐渐松动,导致泵体振幅过大,从而产生大量噪音,对此只需要逐个检查螺栓紧固件即可。此外,安装不够牢固也会导致此问题,需要重新安装。

污水泵不能自动启动怎么回事

污水泵不能自动启动怎么回事?通常是电源电路出现异常,需要对电路系统进行检查,可先查看控制保险有无异常,然后检查转换开关,随后对电压情况进行确认,若电源一切正常则考虑泵体内叶轮或轴承被异物卡死,需要拆泵检查。

关于污水泵不能自动启动怎么回事,简单来说就是根据故障表现形式来逐步拆解问题,详情可参考由中成螺杆泵业带来的以下方式。

YI、DIANJICHUXIANGUZHANGDAOZHIWUFAQIDONG

排污泵电机的电压过低会导致无法正常开机,故而要对整个电源系统进行检查,在合闸电机不运行也无声音,可判断为电路不通,考虑断路,需要检查保险是否完好,然后排查电机定子绕组有无烧毁;若合闸后电机不运行但有声响,则在停机后对电源线及定子绕组进行检查。
