Abstract
A high suction pressure thrust load balance assembly configured for use with a single screw compressor includes comprises a sealing baffle that is keyed to, so as to be rotatable along with, a main rotor drive shaft of the single screw compressor. The sealing baffle is configured to create a force or load to counteract the axial force of the main rotor drive shaft created during rotation of the main rotor drive shaft using the pressurized oil used to lubricate the mechanical shaft seal of the compressor.

A high suction pressure thrust load balance assembly configured for use with a single screw compressor comprising a sealing baffle that is keyed to, so as to be rotatable along with, a main rotor drive shaft of the single screw compressor, wherein the sealing baffle is configured to create a force or load to counteract an axial force of the main rotor drive shaft created during rotation of the main rotor drive shaft.
A single screw compressor comprising:
- a housing;
- a main rotor that is secured within the housing and rotatably driven by a main rotor drive shaft about a main rotor drive shaft axis, and operably engaged with a plurality of gate rotors that are also secured within the housing;
- and
- a high suction pressure load balance assembly, the assembly comprising
- a sealing baffle that is keyed to, so as to be rotatable along with, the main rotor drive shaft,
- and wherein the sealing baffle is configured to create a force or load to counteract an axial force of the main rotor drive shaft created during rotation of the main rotor.
A method of operating a single screw compressor in a high input or suction pressure environment, the method comprising:
- providing the single screw compressor comprising a housing;
- a main rotor that is secured within the housing and rotatably driven by a main rotor drive shaft about a main rotor drive shaft axis, and operably engaged with a plurality of gate rotors that are also secured within the housing;
- and a high suction pressure load balance assembly, the assembly comprising a sealing baffle that is keyed to, so as to be rotatable along with, the main rotor drive shaft;
- creating a high input or suction pressure condition in which a suction pressure is created and is about greater than or equal to 300 psi.
