摘要

介绍了高效真空抽气系统组成及工作原理，在原有射水真空抽气系统的基础上，新增SXCQ-33-Y-11型高效真空抽气系统，对9MW余热电站汽轮机真空抽气系统进行了改造。改造后，新系统使用功率仅为11kW，工作液由易气化的水改为32/46#机油，水电消耗大幅减少，同时，系统结构简单，占地面积小，维护工作量少。

Abstract:

The composition and working principle of the high-efficiency vacuum pumping system are introduced. On the basis of the original water jet vacuum pumping system, SXCQ-33-Y-11 high-efficiency vacuum pumping system is added, and the steam turbine vacuum pumping system of 9 MW waste heat power station is reformed. After the transformation, the power of the new system is only 11 kW, and the working fluid is changed from easily gasified water to 32/46# oil. The water and electricity consumption is greatly reduced. At the same time, the system structure is simple, and the land occupation and maintenance are small.

Key words: waste heat power generation vacuum pump air extraction system steam turbine
