水泵為什么會漏水，
1、水泵漏水原因
(1)安裝水泵時，水封座圈總成未安裝到位，造成水泵繼續(xù)漏水。由于與檢視孔對應(yīng)的泵軸上有擋(甩)水圈，當(dāng)水封漏水時，冷卻水順泵軸遇擋水圈時會從水泵的檢視孔向外甩出及滴露，這樣可防止冷卻水流入軸承內(nèi)破壞潤滑。另外，在更換擋水圈時不注意清除泵體與泵蓋之間不能很好地結(jié)合和密封，也會造成水泵漏水。
⑶工程機(jī)械工作環(huán)境惡劣，容易造成膠木密封墊與襯套端面的磨損不均勻;彈簧長期在水中浸泡，易銹蝕、彈力下降，也能引起漏水。
⑷冬季忘記放水或放水不凈，以及放水時溫度過高，冷卻系內(nèi)水蒸氣凝結(jié)后結(jié)冰，都有可能造成水泵泵體被凍裂，導(dǎo)致漏水。
⑵機(jī)器老舊，水封內(nèi)機(jī)件磨損、銹蝕和老化失效，亦是水泵漏水的原因。當(dāng)工程機(jī)械長期停放時，因發(fā)動機(jī)內(nèi)沒有冷卻水，造成膠木密封墊因干結(jié)、收縮而變形;加水后膠木密封墊雖會膨脹但不能完全恢復(fù)原狀，必將引起少量漏水。另外，對于新安裝的水泵，膠木密封墊與鑄鐵襯套尚未完全磨合好，也將導(dǎo)致水泵少量漏水。
