Description of drawings
Below in conjunction with the drawings and specific embodiments feature and advantage of the present utility model are described, wherein:
Fig. 1 is the scroll compressor sectional view that is provided with an embodiment's of the utility model oil return apparatus.
Fig. 2 is the rear view (being the A-A sectional drawing of Fig. 1) that is provided with an embodiment's of the utility model the quiet whirlpool of the scroll compressor of oil return apparatus dish.
Embodiment
Fig. 1 is an embodiment's of the utility model a scroll compressor sectional view.This compressor has mainly comprised several big parts such as back body 1, the spring piston 2 of compressor, quiet whirlpool dish 3, movable orbiting scroll 4, compressor main shaft 6.Wherein quiet whirlpool dish 3 is located at rear in the body 1 of back, and its center is provided with exhaust port 30, and it is exhaust gas region that 3 rears are coiled in quiet whirlpool.Scroll compressor drives movable orbiting scroll 4 pressurized gass are entered compressor by the exhaust port 9 in the middle of the quiet whirlpool dish 3 exhaust gas region with main shaft 6.Because the inside of compressor has added the lubricant oil of lubricate in advance, and lubricant oil can be discharged into exhaust gas region with the form of little oil droplet and the gas formation mist of oil of High Temperature High Pressure in whole compression process.In order to reclaim these lubricant oil, prevent that the inside oil content of compressor from reducing, the lubricating status variation, coil 3 back sides in quiet whirlpool oil return apparatus is set.
Fig. 2 is the rear view (A-A that is Fig. 1 is to sectional drawing) of an embodiment's of the utility model quiet whirlpool dish.Oil return apparatus of the present utility model is arranged in the dish back side, quiet whirlpool, and it comprises a plurality of baffles 11 (shown in Fig. 2 4), circle separation rib 14 and the Oil-gas Separation chamber 13 that is separated by baffle and separation rib, exhaust cavity 15 and a shoe cream room 17 etc.Launch to describe with regard to the detailed structure of oil return apparatus below.
Four baffles 11 are located at around the exhaust port 30 of quiet whirlpool dish 3, and the air-flow that forms directing exhaust gas hole 30 effluent air guide channel 12 towards periphery.Preferably, four baffles 11 are that benchmark distributes ringwise with 3 centers of coiling, quiet whirlpool, and the gas flow guiding passage 12 that their form is tangent with the circumference of exhaust port 30, and the air-flow of discharging from exhaust port 30 with guiding 13 goes in ring and flows around the Oil-gas Separation chamber.
One circle separation rib 14 is located at the periphery of four baffles 11, the exhaust gas region that quiet whirlpool is coiled 3 rears is separated into Oil-gas Separation chamber 13 and exhaust cavity 15, wherein Oil-gas Separation chamber 13 is between separation rib 14 and baffle 11, it communicates with gas flow guiding passage 12, and exhaust cavity 15 outside separation rib 14 and quiet whirlpool coil between 3 edges.Because every the gas flow guiding passage is the generation source with exhaust port 30 tangent directions of quiet whirlpool dish 3 all, exhaust port 30 effluent airs can keep the high airspeed of trying one's best like this, thereby can form the air-flow that goes in ring in Oil-gas Separation chamber 13.Higher flow line speed helps to improve the effect of Oil-gas Separation.Under gas goes in ring process of flowing, thereby can producing centrifugal phenomenon, the mist of oil/oil droplet that attaches in the gas from high speed airflow, is separated, make the continuous bottom that must deposit to Oil-gas Separation chamber 13 of oil droplet by bump separation rib 14.On separation rib 14,, be provided with an oil-return groove 16 near the position of bottom, Oil-gas Separation chamber.Oil-return groove 16 has been communicated with the bottom and the shoe cream room 17 of being located at exhaust cavity 15 bottoms in Oil-gas Separation chamber 13.Preferably, the obtuse angle of the angled α of tangent direction that offers direction and belt air-flow of oil-return groove 16.Preferably, α 〉=150 °.So both can sneak into the lubricant oil in Oil-gas Separation chamber 13 and return shoe cream room 17 from oil-return groove 16 following gas, obtuse angle alpha have avoided gas flow guiding passage 12 directly in the face of oil-return groove 16 caused leakages simultaneously.In dish 3 positions that are positioned at shoe cream room 17, quiet whirlpool a spill port 18 that connects quiet whirlpool dish 3 is arranged, so just formed one and coiled 3 from quiet whirlpool and 15 return the oil return line of internal body again to shoe cream room 17 to Oil-gas Separation chamber 13 to exhaust cavity.
On the other hand, separation rib 14 is provided with the Oil-gas Separation exhaust port 140 that is communicated with Oil-gas Separation chamber 13 and exhaust cavity 15, is used to make gas to enter exhaust cavity 15 from Oil-gas Separation chamber 13.Preferably, Oil-gas Separation exhaust port 140 is an acute angle with the angle of the tangent direction of belt air-flow, so that the gas of discharging keeps higher linear velocity.Quiet whirlpool is coiled 3 dorsal edge and is provided with exhaust outlet of compressor 150, and the gas of exhaust cavity 15 is discharged from compressor.
Top description only is for principle of the present utility model is described.In addition, to those skilled in the art, can be easy to carry out various modifications and modification, therefore, also do not wish the utility model is restricted in diagram and described concrete structure of literal and the application, all suitable distortion and equivalence are replaced and all are considered to drop in the utility model appended claims and their the equivalent mode of execution scope.
