Abstract
Vertical long-shaft pump is a new generation of energy-saving and environmentally friendly lifting pumpapplied in the field of nuclear power in recent years.lts structural design uses excellent hydraulic model.it also has the characteristics of high efficiency,energy saving,reliability and good suction.Not only the guide vanepump body is used in the design,but also the radial stress is eliminated compared with the volute body,so as to ensurthat the long shaft pump can be more stable and reliable when running.lt can bear the transmission of high viscosityhigh temperature less than 80C and solid particle size less than 8%of the medlum,has been widely used in electricpower,mining,metallurgy,environmental protection,pharmaceutical and petrochemical and other fields.However,inthe production and operation of the vibration is often out of the problem,in the treatment of pump vibration must befrom a wide field of vision multi-angle comprehensive analysis,only in this way can more effectively the pump groupvibration problem thoroughly control within the design allowed range,To this end,the vertical long shaft pumpequipment design,supply,construction and trial operation of the common problems and defects were analyzed one byone,and put forward the corresponding treatment measures,for colleagues to learn from.关键词
