Compressor Unit

Abstract

The invention relates to a compressor unit, in particular for underwater operations, comprising a compressor with a rotational axis and an electric motor. Said compressor unit has a housing with an automation unit for control and regulation tasks. The aim of the invention is to improve the co-operation of the automation unit and the compressor unit and in particular to reduce the complexity of the cooling of the automation unit and signal and energy transmission. To achieve this, an additional housing, which contains the automation unit, is attached to the housing.

       10 . A compressor unit for underwater operation, comprising:
 a rotation axis and an electric motor;   a housing with an inlet and an outlet for a pumping medium;   an automation unit that carries out open-loop and closed-loop control tasks for the compressor unit, wherein an additional housing in which the automation unit is arranged, is arranged on the housing.   
   
   
       11 . The compressor unit as claimed in  claim 10 , wherein the additional housing is thermally conductively fitted to the housing in the area of an intake connecting stub of the inlet such that the power lost from the automation unit is dissipated via thermal conduction to the housing. 
   
   
       12 . The compressor unit as claimed in  claim 11 , wherein the pumping medium is natural gas, and the compressor unit is constructed and suitable for underwater operation. 
   
   
       13 . The compressor unit as claimed in  claim 12 , wherein the automation unit is connected to components via internal signal lines and/or internal power supply lines. 
   
   
       14 . The compressor unit as claimed in  claim 13 , wherein the components are magnetic bearings and/or the motor. 
   
   
       15 . The compressor unit as claimed in  claim 14 , wherein the automation unit is connected to a station via external signal lines and/or external power supply lines. 
   
   
       16 . The compressor unit as claimed in  claim 15 , wherein the additional housing is welded to the housing. 
   
   
       17 . The compressor unit as claimed in  claim 16 , wherein the additional housing has a closeable opening. 
   
   
       18 . The compressor unit as claimed in  claim 17 , further comprising a cooling system which provides a tap and is designed such that the compressor unit is cooled via the pumping medium.
