•INLET VALVE ASSEMBLY
MARK COUPLING HALVES HERE PRIOR TO REMOVAL
ON NEW QSI 1000’S,1250’S AND 1500’S THE COUPLING MUST BE ALIGNED PRIOR TO THE COMPRESSOR GOING INTO SERVICE. THE QSI 245,370,500 AND 750 HAVE A PERMANENT TRANSITION PIECE BETWEEN THE DRIVE MOTOR AND THE INLET HOUSING ON THE BASIC AIREND THAT ELIMINATE THE NEED FOR A COUPLING ALIGNMENT. ON QSI 1000,1250 AND 1500’S THE COUPLING ALIGNMENT SHOULD BE RECHECKED ONCE A YEAR OR ANY TIME THAT THE COMPRESSOR IS MOVED.
SEAL WEAR SLEEVE
TRIPLE LIP SEAL
THE TRIPLE LIP SEAL IS INSTALLED IN A SEAL ADAPTER THAT BOLTS TO THE FRONT OUT SIDE OF THE AIR INLET HOUSING. THE ROTOR DRIVE SHAFT GOES THROUGH THE CENTER OF THE SEAL.
DRIVE COUPLING
THE QSI PRODUCT LINE USES A FLEXIBLE DROP OUT STYLE DRIVE COUPLING. THIS COUPLING IS OF A SPECIAL DESIGN TO ELEMENT THE SPECIAL HARMONIC VIBRATION THAT ARE PRODUCED EXCLUSIVE BY ROTARY SCREW AIR COMPRESSORS. THE COUPLING ASSEMBLY CONSIST OF TWO COUPLING HALVES BOLTED TO STEEL DRIVE HUBS THAT ATTACH TO THE DRIVE MOTOR SHAFT AND THE COMPRESSOR INPUT SHAFT.

COMPRESSOR SHAFT SEALS
QSI COMPRESSORS USE A TRIPLE LIP SHAFT SEAL WITH REPLACEABLE WEAR SLEEVE AND SCAVENGE CAVITY. THE SHAFT SEAL CONSIST OF A WEAR SLEEVE THAT IS PRESSED ONTO THE DRIVE ROTOR SHAFT BEFORE THE DRIVE ROTOR SUCTION BEARING. THIS SLEEVE IS INSTALLED BY HEATING THE SLEEVE AND DRIVING IT ONTO THE PRECOOLED SHAFT TO OBTAIN A NEGATIVE PRESS FIT. A THIN FILM OF LOCK TITE IS APPLIED TO THE INNER PART OF THE WEAR SLEEVE PRIOR TO BEING DRIVEN ON WITH THE SPECIAL INSTALLATION TOOL.

BETWEEN THE TRIPLE LIP SEAL AND THE OUTER DUST COVER IS A SCAVENGE CAVITY THAT DIRECTS ANY LUBRICANT THE MIGHT PASS THE SEAL TO BE RETURNED TO THE INLET WHEN THE COMPRESSOR IS OPERATING. THIS SCAVENGE RETURN LINE IS EQUIPPED WITH A CHECK VALVE AT THE INLET VALVE HOUSING THAT PREVENTS LUBRICANT FROM FLOWING BACK FROM THE BASIC AIREND TO THE SCAVENGE CAVITY WHEN THE COMPRESSOR IS SHUT DOWN.
