| Abstract: | Several surveys have shown that shaft sealing and bearing breakdown are encountered frequently during the chemical pump operating. The articale analyses the reasons of the breakdowns, and then put out the innovative approach of the chemical process pump design to solve such problems. Radial suction chamber and low pressure shaft seal are designed to realize pump to be leakproof totally. The design of a guide vane diffuser fitted with a circular diffuser flow channel is used to eliminate any side thrust on the shaft. Thus, not only the working conditions of sealing and bearing are improved obviously but also prolong the life of operating pump and make running of a pump much more reliable. |
