PERFORMANCE IMPROVEMENT STRUCTURE OF A LARGE-CAPACITY AIR COMPRESSOR WITH A SLIT BROWING ON SUCTION DUCT

摘要

It relates to the performance improvement structure of a large-capacity air compressor that applies a slit blowing to the suction passage, In a large-capacity air compressor that supplies air sucked through the suction duct to the impeller of the compression unit, a slit is formed around the outer periphery of the suction duct and high-pressure air is supplied to the slit to generate low-speed flow within the boundary layer of the suction duct. Through technology configuration that activates the area up to the speed of the outer area of the boundary It is possible to greatly improve the compression efficiency of a large-capacity air compressor by activating the low-speed flow area inside the boundary layer permanently occurring upstream of the compression unit without a separate additional device for activating the boundary layer flow or a risk of failure.
