摘要
针对循环水泵进口管橡胶膨胀节出现的气囊而产生的气阻现象，对膨胀节进行改造，在气囊区开孔安装排气管，使泵的扬程和效率达到设计要求，收到了较理想的效果。
The air-pocket existing in the rubber expasion knot of the inlet tube of the circulatingwater pump led to air-blocking.In the light of this phenomenon,the expansion knot was revamped.Ahole was drilled to install an air exhaust pipe in the air-pocket zone to make the lift and efficiency ofthe pump reach the designed standard.
