    济南水泵维修专家谈汽蚀的防止措施

    济南水泵维修http://www.water-nj.com/专家介绍首先屏蔽泵的实际安装高度,必须低于或等于水泵的实际吸水高度。水泵的进水口吸水管路尽可能地缩短长度,弯头和阀门要少,有些养殖生产单位的水泵弯头作成直角,而不是采用虾壳弯的方式,这样会使吸水管的阻力加大,容量抽空而产生汽蚀,严格遵守水泵铭牌上的额定参数。
    Ji'nan water pump maintenance expert introduction of the actual installation of the pump must be lower than or equal to the actual water absorption of the pump. Increase the water inlet of the water suction pipe as far as possible to

    shorten the length, elbow and valves should be less, some aquaculture production unit of water pump elbow into rectangular, rather than the shrimp shell bending, this will enable the suction pipe resistance, capacity of evacuating and cavitation, strictly abide by the water pump nameplate ratings.

    济南水泵维修http://www.water-nj.com/专家分析进水管路的接头、胶垫一定要严密可靠,应经常检查接头法兰螺栓的紧固情况,吸水底阀的启闭应灵活(尤其是久放不用的水泵机组),杜绝抽水过程中的不断停泵。不要认为吸水管淹得深一些就会提高吸水高度,其实这样做适得其反。因为过大的淹没深度加长了吸水管路,从而使沿程损失增大,结果却减少了吸水高度,也容易吸空而产生汽蚀。

Do not think that the absorption of water pipes will increase the depth of some water absorption, in fact, do just the opposite.Because too large submerged depth increases the suction pipe, thereby increasing the loss along the way, the result has reduced the height of water absorption, but also prone to cavitation and cavitation.
