关于单螺杆泵的日常维护

来源: 时间:2021-01-20 21:18:43 次数:

1.单螺杆泵剧烈振动:可能电动转子不平衡,或联轴器结合不良,轴承磨损弯曲;也可能转动部分零件松动、破裂;也许是因管路支架不牢固等。可分别采取调整、修理、加固、更换等办法处理。

2.管路漏水或漏气:可能安装时螺帽拧得不紧。若渗漏不严重,可在漏气或漏水的地方涂抹水泥或用沥青油拌和的水泥浆。临时性的修理可涂些湿泥或软肥皂。若在接头处漏水,则可用手拧紧螺帽。漏水严重的必须重新拆装。

3.填料过热:多因填料压得太紧,冷却水进不到填料内,或轴表面损坏。可采取适当放松填料、清理封管堵塞等措施。填料磨损必须更换新的。安装前在机油内浸透,逐圈装入,切口要错开,这样可减少漏水。后一圈填料装好后,要装紧压盖,运转时再调整松紧度。
