Abstract
PURPOSE: To reduce noise in screw compressor, the level of oil separated from the element and stored in the housing is set the level below the bottom of the element.
CONSTITUTION: The level of oil 14 separated from the element 10 and stored in the housing 12 is set to the level below the bottom of the element 10. Cacity resonance frequency depends on the quantity of oil in the housing 12, varying with whether or not the oil level contacts the bottom of the element. The resonance mode in compressor noise is small when horse shoe cavity or liquid level is high. Thus, the oil level setting in this way reduces noise.
