Working procedure of the present utility model: the elementary price fixing 31 of scroll compressor described in the utility model, secondary price fixing 40, air guide support lid 41 form a confined space jointly with motor 42, suction port 48 is connected with evaporating heat exchanger by vaporizer flange 30, and air outlet 49 is connected with condensing heat exchanger by condenser flange 38.
The power of motor 42 turns by main the elementary balance 32 of balance finger 36 that axle 37 is passed to the balance finger 36 at secondary balance 39 → its back side → synchronously turn wheel 35 → elementary balance 32 back side successively.
The gas compression path of scroll compressor 4 is as shown in Figure 15, Figure 16, gas enters the region 50 of helical coil 33 outmost turns → through the swing of elementary balance by suction port 48, gas to enter successively in 51 → Crescent area, meniscate region 52 → until near the region 53 of elementary gas port → enter secondary chamber 54 → again through the swing of secondary balance by elementary gas port 46 and gas port 43, and gas to enter successively in 55 → Crescent area, meniscate region 56 → until near the region 57 of secondary gas port → derive outdoor 58 by secondary gas port 50.
Advantage of the present utility model: because secondary balance 39 and elementary balance 32 are subject to the restriction of balance positioning disk 34, it can only be parallel to the orbiting motion that spin axis makes circle.After the helical coil 33 on balance and price fixing engages each other, when circle swing made by balance, price fixing and balance periphery gas can be made to wriggle toward heart gradually, make gas obtain the compression of gradual change.Master turns axle 37 and often turns over an angle, and smaller volume unit, pressure uprises a unit.Volume or pressure are progressively change procedures.Therefore, main axle 37 load in period of rotation that turns is steady, very quiet when feature is for running.
The utility model adopts Two-stage Compression, can reduce the vibrations that when balance moves, eccentric mass causes; In addition, turn axle realize rolling friction by main, solve the defect do not grown in working life that sliding friction in prior art brings, and do not need profit oil.In addition, in the course of the work, power is uniform to the utility model, the power of piston compressor pulsation in hinge structure, thus running is more steady, quiet.
The utility model adopts Two-stage Compression, and its object is:
1, the geometric ratio of saturated gas can be realized without sudden change compression, the low pressure saturated gas come by vaporization chamber gradually reduces and is pressurized to high pressure saturated gas and removes condensation chamber, in the course of the work, power is uniform, the pulsating force that in hinge structure, piston compressor produces, thus running is more steady, quiet;
2, because of the eccentric swing of primary and secondary balance, the vibrations that can balance and cause when eccentric mass reduces balance motion are arranged with axisymmetric;
3, master turns axle and synchronously turns wheel and realizes rolling friction by rigid bearing, solves by the defect that the working life that crosshead shoe sliding friction brings is not grown in prior art, and no longer needs to use thin oil lubricant.
