Description
Technical field
The utility model relates to a kind of rotary type air condition compressor.
Background technique
Rotary type air condition compressor, is mainly made up of shell 101, pumping, liquid-storage container 102, stator 103 and rotor 104, and pumping comprises cylinder 105, axle 106, ring 107, baffler 108, upper bearing bracket 109 and discharge valve, as shown in Figure 1.On cylinder 105, be provided with blade groove, cylinder suction port and cylinder exhaust port, cylinder 105 sucks cold media air, and cylinder internal is rotated by an eccentric shaft band rotating ring, and compression ring forms in the orbiting of cylinder internal.
Cylinder 105 inner high voltage sides and low voltage side refrigerant pressure are separated by the oil film of blade and cylinder body, until high voltage terminal gas is while being compressed into a certain pressure, discharge valve is opened and pressurized gas discharge, discharge valve is positioned at upper bearing bracket position and joins with cylinder, mouth pressure venting one's pent-up feelings is very large, the pulse meeting of pressure enters outlet pipe, and impulse oscillation can cause noise and the vibrations of system.
Model utility content
For the above-mentioned technical problem existing in prior art, the utility model proposes a kind of rotary type air condition compressor, can effectively absorb exhaust pulses, reach the object that reduces noise.
To achieve these goals, the utility model adopts following technological scheme:
A kind of rotary type air condition compressor, comprise shell, top cover, pumping, stator, rotor, liquid-storage container and bottom, on top cover, be provided with outlet pipe, on liquid-storage container, be provided with sucking pipe, pumping comprises cylinder, axle, ring, silencer cover, upper bearing bracket and discharge valve, discharge valve is positioned at upper bearing bracket position and is connected with cylinder, on cylinder, be provided with blade groove, cylinder suction port and cylinder exhaust port, described cylinder exhaust port place is provided with a buffer cavity, between buffer cavity and cylinder exhaust port, is provided with connecting passage.
Further, the cylindrical shape of described buffer cavity, the diameter of section of buffer cavity is 4.0～4.2mm, the degree of depth is 1.8～2.2mm.
Further, the described connecting passage column that is square, the length of connecting passage is 1.5～1.7mm, and width is 1.5～1.7mm, and the degree of depth is 0.5～0.7mm.
The utility model has the advantages that:

Brief description of the drawings
Fig. 1 is the structural representation of rotary type air condition compressor in prior art;
Fig. 2 is the structural representation of rotary type air condition compressor in the utility model;
Fig. 3 is the structural representation of cylinder in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Shown in Fig. 2 and Fig. 3, a kind of rotary type air condition compressor, comprise shell 201, top cover 202, pumping, stator 203, rotor 204, liquid-storage container 205 and bottom 206, on top cover, be provided with outlet pipe 207, on liquid-storage container, be provided with sucking pipe 208, pumping comprises cylinder 209, axle 210, ring, silencer cover, upper bearing bracket 211 and discharge valve, discharge valve is positioned at upper bearing bracket 211 positions and is connected with cylinder 209, on cylinder, be provided with blade groove 212, cylinder suction port 213 and cylinder exhaust port 214, cylinder exhaust port 214 places are provided with a buffer cavity 215, the cylindrical shape of buffer cavity 215, between buffer cavity 215 and cylinder exhaust port 214, be provided with connecting passage 216, connecting passage 216 column that is square.By buffer cavity 205 being set at cylinder exhaust port 214 places, can effectively absorb exhaust pulses, reach the object that reduces noise.In compressor production process, buffer cavity 215 is made by bore process, and connecting passage 216 is made by extrusion process.
Cylinder 209 increases buffer cavity 215, although can improve noise, but can reduce to a certain extent the volumetric efficiency of compressor and then the Energy Efficiency Ratio of reduction rotary type air condition compressor, therefore the volume of buffer cavity 215 has strict restriction, through evidence, the diameter of section of buffer cavity 215 is that 4.0～4.2mm, the degree of depth are while being 1.8～2.2mm, can ensure under the condition of improving noise, to reduce to greatest extent the loss on compressor performance, on noise, obtain and improve accordingly and be applied on the machine that height of cylinder is greater than 20.5H.In order to match with the design of buffer cavity 215, the length of connecting passage 216 is 1.5～1.7mm, and width is 1.5～1.7mm, and the degree of depth is 0.5～0.7mm.
Certainly; more than explanation is only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification; that makes is allly equal to alternative, obvious variant, within all dropping on the essential scope of this specification, ought to be subject to protection of the present utility model.
