ABSTRACT:
In a turbo machine, for example, a turbo compressor, the rotor shaft extends through and is sealed relative a housing via dry gas seals in which a seal clearance is achieved between a rotating, sealing body and a non-rotating sliding body in which the inner side of the dry gas seal is charged with a barrier gas, with the leakage of the dry gas seal being dammed via a back-up plate and the dynamic pressure is monitored via a pressure inspection device, wherein due to increasing dynamic pressure an alarm is given off or the turbo machine is automatically shutdown without delay so that the exit of gas, particularly of toxic or explosive gas from the inner area of the housing of the turbo machine is avoided, wherein, via the use of multiple seals the leakage pressure of one of the inner dry gas seals can initiate a warning or alarm signal and via the leakage pressure of the outer dry gas seal, the turbo machine can be shut down.
