Abstract
A drive system for a multistage screw compressor with a first compressor stage with a first main rotor mounted on a first shaft in a torque-proof manner and a second compressor stage with a second main rotor mounted on a second shaft in a torque-proof manner. The drive system has a drive shaft for driving the shafts of both main rotors of the first and second compressor stages, wherein the driving of the shaft of the first main rotor takes place independently of the driving of the shaft of the second main rotor, so that the rotational speeds of the two main rotors can preferably be adapted independently of one another.
Claims20
A drive system for a multistage screw compressor comprising:
- a housing including a housing cavity, a fluid inlet and a fluid outlet;
- a first compressor stage including a first main rotor mounted on a first shaft in a torque-proof manner, the first shaft defining a first shaft axis;
- a second compressor stage including a second main rotor mounted on a second shaft in a torque-proof manner, the second shaft defining a second shaft axis parallel to the first shaft axis and;
- a drive shaft configured to respectively drive the first shaft of the first main rotor and the second shaft of the second main rotor of the first and second compressor stages,
- wherein the housing houses the first compressor stage, the second compressor stage and the drive shaft within the housing cavity, and where the drive shaft is configured to drive the first shaft of the first main rotor independently from the second shaft of the second main rotor.
A screw compressor comprising:
- a housing including a housing cavity, a fluid inlet, and a fluid outlet;
- a first compressor stage with a including a first main rotor mounted on a first shaft in a torque-proof manner, the first shaft defining a first shaft axis;
- a second compressor stage including a second main rotor mounted on a second shaft in a torque-proof manner, the second shaft defining a second shaft axis parallel to the first shaft axis and;
- a drive system for driving the screw compressor, the drive system including:
- a drive shaft configured to respectively drive the first shaft of the first main rotor and the second shaft of the second main rotor of the first and second compressor stages,
- wherein the housing houses the first compressor stage, the second compressor stage, and the drive system within the housing cavity, and where the drive shaft is configured to drive the first shaft of the first main rotor independently from the second shaft of the second main rotor.
