Technical field
The present invention relates to a kind of rotary vane compressor.Particularly relate to a kind of relevant only need simply operating valve just can make its in the inboard compression chamber or outside compression chamber compress, and can change the capacity varying device of the rotary vane compressor of compressor capacity according to mode switch.
Background technique
Generally, rotary vane compressor is that rotation blade is rotated motion in the inside of the cylinder with suction port, and compression flows into the cold media air of cylinder interior, according to the shape of blade polytype rotary vane compressor can be arranged.
Fig. 1 is the vertical section structure figure of common rotary type rotary vane compressor.
As shown in Figure 1, rotary vane compressor, upper side motor section D and lower side press part P are enclosed in shell 1 inside, and motor section D utilizes vertical running shaft 6 to interconnect with press part P, and running shaft 6 possesses eccentric part 6a.
Motor section D comprises by stator 2 Hes that are fixed on shell 1 inside, is arranged on the internal condition power turn-on of stator 2 and rotates and drive vertical running shaft 6 rotor rotated 3 that connect in it and constitute.
The structure of press part P is: under the eccentric part 6a of running shaft 6 effect, rotation blade 4 is in the rotation of the inside of cylinder 5, and compression is drawn into the cold media air of cylinder 5 inside by suction port 51.Therefore, cylinder 5 has interior side ring 52, and is formed with annular working space 53 between the inwall of interior side ring 52 and cylinder 5, and the scrollwork 40 that makes rotation blade 4 forms compression chamber in the medial and lateral of scrollwork 40 thus in working space 53 inner rotations.
And, be equipped with the two ends of main bearing 7 and supplementary bearing 7a supporting rotating shaft 6 in the upper and lower part of press part P, on supplementary bearing 7a, be formed with discharge side 8a by baffler 8, discharge side 8a discharges stream 9 with the catheter shape of vertical perforation press part P and main bearing 7 and is connected, and compression refrigerant gas is discharged to the inside of shell 1 by discharging stream 9.
Here, unaccounted symbol 11 is suction leads, the 12nd, discharge conduit, and 10a is the Oudan ring that prevents autobiography mechanism.
The swirl type rotary vane compressor of Gou Chenging as mentioned above, according to power turn-on, the rotor 3 of motor section D drives, and axial rotary is combined in the running shaft 6 on the rotor 3, and according to the rotation of running shaft 6, the rotation blade 4 that is installed on the eccentric part 6a of running shaft 6 is rotated motion.
Therefore, working space 53 inside at cylinder 5, the scrollwork 40 of rotation blade 4 is rotated motion, so the cold media air that is drawn into cylinder 5 inside by suction port 51 is compressed in two compression chambers that formed by scrollwork 40, and the cold media air of compression is like this discharged to discharge side 8a by the medial and lateral exhaust port (not shown) of cylinder 5 and supplementary bearing 7a, the high pressure refrigerant gas of Pai Chuing is discharged to the inside of shell 1 again by discharge stream 9 like this, finishes the conveying of compression refrigerant gas by discharging conduit 11 thus.
Fig. 2 is the working state schematic representation of the compression process of Fig. 1.
Press part P rotates to the direction of arrow in the inside of working space 53 according to the scrollwork 40 of rotation blade 4 as shown in the figure, and compression is drawn into the cold media air of working space 53 inside by suction port 51.Describe the effect of press part P below in detail.
Promptly, under 0 ° of initial working state, inboard suction chamber A1 by suction port 51 and scrollwork 40 sucks cold media air, and the outside compression chamber B2 of scrollwork 40 beginning compression refrigerant gas under the state that suction port 51 and outboard row outlet 53b is blocked, inboard compression chamber A2 compresses simultaneously cold media air and discharges.
Under the state of 90 ° of rotations, compression in the outside compression chamber B2 of scrollwork 40 is in the middle of carrying out, and the inboard compression chamber A2 of scrollwork 40 is almost to be the state of having arranged compression refrigerant gas by inboard row outlet 53a, appear at non-existent outside suction chamber B1 previous stage in addition, suck cold media air by suction port 51.
Under the state of 180 ° of rotations, the inboard suction chamber A1 that exists in previous stage disappears, and replaces it, and inboard suction chamber A1 becomes inboard compression chamber A2 and begins compression refrigerant, outside discharge side B2 is communicated with outboard row outlet 53b in addition, discharges the cold media air after compressing.
Under the state of 270 ° of rotations, the outside compression chamber B2 of scrollwork begins to discharge cold media air after the compression by outboard row outlet 53b, and inboard compression chamber A2 also continues compression refrigerant, and outside suction chamber B1 begins compression refrigerant.If half-twist once more under above-mentioned state, the outside suction chamber B1 of previous stage becomes outside compression chamber B2, outside compression chamber B2 gets back to initial state when beginning compression refrigerant, continuous so thus 1 circle that is rotated axle repeatedly rotates to be the circulation of benchmark.
Here, unaccounted symbol 55 is the slide blocks for sealed high pressure portion and low voltage section.
The energy-saving operation of refrigeration such as refrigerator or air-conditioning or refrigeration plant is: in the cabinet or indoor temperature reach setting temperature, then stop compressor operation, in the cabinet or indoor temperature rise to more than the setting temperature, then restart compressor, start/stop the purpose that compressor operation reaches refrigeration so repeatedly.Common compressor consumes the more electric power of volume when more normally turning round when starting, and when shutting down suddenly and start suddenly inside cause parts to wear and tear fast because of influencing each other between the load of pressurized gas and the parts, shortened the life-span of compressor thus.
Therefore, require compressor do not have foregoing start repeatedly/shut down also can change compression volume.The method that can change the compressor compresses capacity has by controlling and driving portion, that is, the rotation number by the conversion motor changes frequency conversion mode of compression volume etc.But the frequency conversion mode need be equipped with the circuit control device and the parts of high price, so cost of production rises, causes the product price competitive ability to descend.
