Abstract
The invention relates to an open type scroll compressor without oil lubrication. The scroll compressor is characterized in that: a crankshaft (15) is arranged on a support body (6) through a main bearing (20) and an auxiliary bearing (16); a moving scroll disc (8) and a static scroll disc (5) which are staggeredly arranged are engaged with each other to form an enclosed compression chamber to realize the compression of a gas medium; the static scroll disc (5) is symmetrically provided with two air inlets (1), and the center of the static scroll disc (5) is provided with a gas exhaust vent (2); the scroll addendum of the static scroll disc (5) and the scroll addendum of the moving scroll disc (8) are inlayed with a self-lubricating material; the exhaust side of the static scroll disc (5) is provided with a cooling water channel (22); the motor driving side of the crankshaft (15) is provided with skeleton sealing rings (12, 14); the moving scroll disc (8) drives a bearing (11) and a small toggle anti-rotation mechanism (4); a support bearing (3) is a self lubricating bearing; an oil storage tank (18) is arranged between the main bearing (20) and the auxiliary bearing (16) which are in the support body (6); and an oil drain hole (19) is arranged under the oil storage tank (18).
Description
Technical field
The present invention relates to the convolute-hydrodynamic mechanics in the fluid capacity-changing mechanism, be specifically related to a kind of non-lubricated vortex formula compressor, it is for can realize that compressed medium cleans the not compressor of oil-containing.
Background technique
Scroll compressor is a kind of positive displacement compressor of high-efficient low-noise; Be widely used in fields such as refrigeration air-conditioner, energetics; Because the specific motion mode of scroll compressor; There are many friction pairs; Present most scroll compressor uses lubricant oil that friction pair is lubricated; Cause and contain lubricant oil in the compressed media, thereby limited the application area of scroll compressor.
Under the rotating speed certain condition; The air displacement of scroll compressor increases along with the increase of dynamic and static scroll physical dimension; The increase of moving eddy's structure size, scroll compressor bent axle force-bearing situation is worsened; Cause the compressor operating state labile; Shorten working life, this also is one of principal element of being restricted of the development of big discharge capacity scroll compressor.
Prior art Chinese patent " a kind of scroll compressor (200510042925.3) ", driving bearing is embedded in the dynamic vortex tooth side, and the moving suffered tilting moment of vortex is little, but realizes that the compression ratio of high pressure ratio is difficult.
Summary of the invention
The objective of the invention is to realize the scroll compressor oil-free lubrication, the compressed media cleaning is oil-containing not, and under the same structure size condition, air displacement is bigger than the air displacement of common scroll compressor.
The present invention is a kind of oil-free lubrication open type scroll compressor; Bent axle 15 is supported with supplementary bearing 16 by main bearing 20 and is installed on the stake body 6; Import power by external motor through belt pulley or coupling; Drive moving scroll 8 and do the revolution translation; Moving scroll 8 interlaces with fixed scroll 5 and settles engagement to form the closed compression chamber; Realization is to the compression of gas medium; On fixed scroll 5, be arranged with two suction ports 1; The center is provided with a relief opening 2; Fixed scroll 5 vortex tooth tops and moving scroll 8 vortex tooth tops are inlaid with self lubricating material; Fixed scroll 5 exhaust sides are provided with cooling water channel 22; Bent axle 15 motor driving sides are provided with backbone sealing ring 12; 14, moving scroll 8 driving bearings 11 are self oiling bearing with little crank throw anti-rotation mechanism 4 spring bearings 3.Stake body 6 internal spindle hold 20 and supplementary bearing 16 between be provided with oil storage tank 18, oil storage tank 18 belows are provided with oil drainage hole 19.
Major advantage of the present invention: (1) compressed medium can realize the clean oil that do not have, and has widened the application area of scroll compressor.(2) adopt double end wrap structure, compare with single head wrap structure, under the same structure size, air displacement increases.(3) fixed scroll exhaust side cooling water channel can reduce the temperature and the fricative heat of gas in the compression process, reduces power consumption.(4) because unlubricated oil has been removed oil supply system and oil circuit, make compact structure, simple.
