INTERNAL VOLUME RATIO ADJUSTMENT OF SCREW COMPRESSOR

PURPOSE:To lesson wasteful loss of motive power by shortening a gas compression range until a screw compressor is unloaded as well as minimizing volume change width at the time of changing from full load drive to unload drive and improving a volume control property.

Zusammenfassung:	PURPOSE:To lesson wasteful loss of motive power by shortening a gas compression range until a screw compressor is unloaded as well as minimizing volume change width at the time of changing from full load drive to unload drive and improving a volume control property. CONSTITUTION:Changeover from full load drive to unload drive is carried out after a slide valve 6 for internal volume ratio adjustment is transferred to the side of a low internal volume ratio in an internal volume ratio adjustment method of a screw compressor provided with a slide valve 5 for internal volume ratio adjustment and the slide valve for volume adjustment.
