TURBOMACHINE HAVING A TEMPERATURE-CONTROLLED COVER

摘要

A turbomachine, comprising a lower housing part, an assembly inserted into the lower housing part from above, comprising two opposite housing covers and a rotor having a shaft, the rotor being fed through both housing covers, and an upper housing part that encloses the assembly from above and is fastened to the lower housing part, is provided. A shaft seal is arranged between the cover and the shaft. To maintain good function of the shaft seal during operation using cold or hot gases, at least one of the covers has a temperature-control means guided around the shaft, having a first and a second temperature-control channel, for controlling the temperature of the lid in the area around the shaft.
