摘　　要：我单位某型升压式涡轮冷却器在生产装配过程中,存在性能调试困难的问题,通过对该涡轮冷却器工作原理和结构进行分析,并经仿真论证,确定调试困难原因为蜗壳刚度不足,导致高压力工况下弹性变形过大,针对该原因提出了改进方案,并进行生产与试验验证,证实改进有效,装配调试困难的问题得到解决,可以为后续涡轮的结构设计提供参考。A booster type of cooling turbine unit in the process of production assembly in my company,performance turning difficult problems.This article through to analysis the operating principle and structure of the cooling turbine unit,and with the simulation verification to identify the cause of the debugging difficulty is the insufficient rigidity of the volute,which lead to the elastic deformation too large under high pressure condition.For this reason put forward the improvement plan,and carries on the production and test,confirm improvement.And the problem of assembly debugging difficult is resolved.This can provide reference for subsequent structure design of the turbine.
