| Abstract: | 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. |
