Description
Technical field
Scroll compressor with injection channel of the present invention relates to the scroll compressor field, is specially the scroll compressor injection channel and reduces noise structure.
Background technique
Present existing scroll compressor comprises the vortex of deciding that is provided with spirality vortex tooth, with the moving vortex that is provided with spirality vortex tooth of deciding vortex and matching, between moving vortex and upper support, move, respectively with moving, decide the vortex cooperation and limit the partition ring that they can only relative translation, by moving vortex and deciding a plurality of compression chambers that vortex has complemented each other to form variable volume, move vortex along its revolution orbit revolution by the driven by motor crank-driven, thereby finish suction, compression and the discharge of gas.For ejector refrigeration agent under some particular service requirements in compression chamber, usually to offer injection channel, to design noise-reducing components for reducing noise simultaneously.
In the prior art, for ejector refrigeration agent under some particular service requirements in compression chamber, usually to offer injection channel deciding vortex, so that refrigeration agent enters compression chamber by the injection channel of deciding to offer on the vortex; For reducing noise, need to design the cup with certain structure shape simultaneously, this cup is fixed to decides on the vortex.
The deficiencies in the prior art are: although deciding can to offer injection channel on the vortex, owing to decided eddy sizes and structural limitations, channels designs is very complicated, and offering of passage can not reach optimum, and the area of passage and the ratio of length are also very large, are unfavorable for processing.
For existing problem in the above-mentioned prior art, a kind of novel scroll compressor with injection channel of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is a kind of novel scroll compressor with injection channel of research and design.Exist in the prior art in order to solve: offer injection channel deciding vortex, owing to decided eddy sizes and structural limitations, channels designs is very complicated, and offering of passage can not reach optimum, the area of passage and the ratio of length are also very large, are unfavorable for the problems such as processing.
Technical solution of the present invention is achieved in that
Scroll compressor with injection channel of the present invention is by housing, loam cake, decide vortex, moving vortex, partition ring, upper support, bent axle, rotor and motor stator and formed; Motor stator is installed in bottom in the housing, rotor is equipped with in the inside of motor stator, rotor is loaded on the bottom of bent axle, upper support and moving vortex are housed on the bent axle, between moving vortex and upper support, partition ring is housed, decide vortex and be fixed on the upper support, decide vortex and moving vortex complements each other to form a plurality of compression chambers, loam cake is placed on the housing; It is characterized in that valve plate is loaded on by the bolt hole on it and screw decides on the vortex; Be processed with the main injection passage on the valve plate and be attached thereto logical injection channel, the bottom of injection channel be processed with decide vortex on the conductive channel that is connected of jetburner; The bottom of valve plate is processed with groove A, and decides vortex sealing and forms space A; On the main injection passage injection pipe is housed.
Scroll compressor with injection channel of the present invention is by housing, loam cake, decide vortex, moving vortex, partition ring, upper support, bent axle, rotor and motor stator and formed; Motor stator is installed in bottom in the housing, rotor is equipped with in the inside of motor stator, rotor is loaded on the bottom of bent axle, upper support and moving vortex are housed on the bent axle, between moving vortex and upper support, partition ring is housed, decide vortex and be fixed on the upper support, decide vortex and moving vortex complements each other to form a plurality of compression chambers, loam cake is placed on the housing; It is characterized in that valve plate is loaded on by the bolt hole on it and screw decides on the vortex; Be processed with the main injection passage on the valve plate and be attached thereto logical injection channel, the bottom of injection channel be processed with decide vortex on the conductive channel that is connected of jetburner; Decide vortex top and be processed with groove B, form space B with the valve plate sealing; On the main injection passage injection pipe is housed.
Be processed with exhaust port on the valve plate of the present invention, compression chamber, scroll exhaust passage space A or space B, exhaust port are connected with exhaust cavity.
Injection channel level of the present invention is machined in the valve plate, and quantity is one or more, and all is connected with the main injection passage; Be processed with a downward identical conductive channel on each injection channel.
Of the present inventionly decide to be processed with on the vortex jetburner that one or more communicate with compression chamber, the quantity of jetburner is identical with the quantity of conductive channel, and main injection passage, injection channel, conductive channel, jetburner and compression chamber are communicated.
Job step of the present invention comprises: part of refrigerant enters compressor by injection pipe, by main injection passage, injection channel, be connected with jetburner on deciding vortex by conductive channel again, enter and decide vortex and moving vortex complements each other to form a plurality of compression chambers, another part refrigerant mixed in this a part of refrigeration agent and the compression chamber, mixed refrigeration agent enters space A or space B via the scroll exhaust passage, enters exhaust cavity by exhaust port again, finally discharges compressor by relief opening.
Advantage of the present invention is apparent, is mainly manifested in:
1, offers the injection channel with certain structure shape at valve plate of the present invention and can guarantee that refrigeration agent enters compression chamber, and because injection channel is opened on the valve plate, that decides that vortex can will not design because of offering injection channel is very complicated, the part of a complexity is divided into two simple parts, processes convenient; Because passage is opened on the valve plate, do not decided eddy sizes and structural limitations simultaneously, it is simpler that passage can design, and more is conducive to processing.
2, the design of the reduction noise of compressor is to adopt extra steel cup to go to finish usually, now has the formed structure space of the groove that satisfies certain volume and shape need on the valve plate in the invention, can when the scroll exhaust, reach certain reduction noise contributions, valve plate can make and cylinder iron wait material, and it is more obvious to reduce noise contributions.
The present invention have novel structure, processing easy, be not subjected to existing equipment size restrictions, noise-decreasing, be convenient to the advantage such as maintenance, it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
