As shown in Figure 1, the present invention includes the motor 42 being arranged on inducing QI support lid 41, inducing QI support lid 41 connects secondary price fixing 40, secondary price fixing 40 connects primary price fixing 31, surround at primary price fixing 31, secondary price fixing 40 and inducing QI support lid 41 and the chamber formed arranges primary balance 32, balance location dish 34 and secondary balance 39, chamber is separated into the primary chamber of the left and right sides and secondary chamber by balance location dish 34, install primary balance 32 in the side of balance location dish 34, the opposite side at balance location dish 34 installs secondary balance 39；The housing of described primary price fixing 31 arranges air inlet 48, inducing QI support lid 41 arranges gas outlet 49, at the centrally disposed secondary gas port 50 of secondary price fixing 40；The power output shaft connection of described motor 42 is main turns axle 37, as shown in figure 12, described master turns one end of axle 37 and is provided with hole and the keyway that the power output shaft connection with motor 42 coordinates, the main other end turning axle 37 is to turn 47 with the main parallel bias of axle 37 axis that turns, bias turn 47 with being connected centrally through bearing of secondary balance 39；
On the face that described primary price fixing 31 is relative with primary balance 32, installation first is to helical coil 33-1, the face that secondary balance 39 is relative with secondary price fixing 40 is installed second to helical coil 33-2；Described first pair of helical coil 33-1 includes two shapes, equivalently-sized helical coil, two mutual intussusceptions of helical coil；Described second pair of helical coil 33-2 includes two shapes, equivalently-sized helical coil, two mutual intussusceptions of helical coil；The import direction of two helical coil in described first pair of helical coil 33-1 and second pair of helical coil 33-2 is 180 ° (as shown in Figure 2)；As it is shown in figure 9, described balance location dish 34 is provided with gas port 43 and three bearing mounting holes 44, gas port 43 is positioned at the center of balance location dish 34, and three bearing mounting holes 44 are evenly arranged in the outer ring of gas port 43 along the circumferencial direction of balance location dish 34；As shown in Figure 10, in three bearing mounting holes 44 of described balance location dish 34, by bearing, synchronization is installed respectively turns wheel 35, as shown in figure 11, described synchronization is turned and is arranged two little bearing mounting holes 45 on wheel 35, and two little bearing mounting holes 45 are arranged symmetrically in synchronization and turn on wheel 35；As shown in Fig. 5～Fig. 8, centrally disposed primary gas port 46 at described primary balance 32, being respectively provided with three balance fingers 36 at primary balance 32 and secondary balance 39 towards the side of balance location dish 34, three balance fingers 36 are evenly arranged along the circumferencial direction of primary balances 32 and secondary balances 39 respectively；Three balance fingers 36 on described primary balance 32 are separately positioned in the little bearing mounting hole 45 that wheel 35 is turned in three synchronizations, and three balance fingers 36 on secondary balance 39 are separately positioned in another little bearing mounting hole 45 that wheel 35 is turned in three synchronizations；
As it is shown on figure 3, described helical coil is wound, by band plate, the bung flange shape that some circles obtain in approximately the same plane around same center, the spacing between each circle of bung flange shape is equal；As shown in Figure 4, a side of described band plate is provided with gap, one side of this gap buries to be cast in the plane of primary price fixing 31, primary balance 32, secondary balance 39 and secondary price fixing 40, makes helical coil be cast as one securely with primary price fixing 31, primary balance 32, secondary balance 39 and secondary price fixing 40.
The work process of the present invention: the primary price fixing 31 of screw compressor of the present invention, secondary price fixing 40, inducing QI support lid 41 collectively constitute a confined space with motor 42, air inlet 48 is connected with evaporating heat exchanger by vaporizer flange 30, and gas outlet 49 is connected with condensing heat exchanger by condenser flange 38.
The power of motor 42 is transferred to the primary balance 32 of balance finger 36 at the balance finger 36 at secondary balance 39 → its back side → synchronize to turn wheel 35 → primary balance 32 back side successively by the main axle 37 that turns.
The gas compression path of screw compressor 4 is as shown in Figure 15, Figure 16, gas is entered the region 50 of helical coil 33 outmost turns → through the swing of primary balance by air inlet 48, gas sequentially enters in 51 → Crescent area, meniscate region 52 → until near the region 53 of primary gas port → entered secondary chamber 54 → again through the swing of secondary balance by primary gas port 46 and gas port 43, and gas sequentially enters in 55 → Crescent area, meniscate region 56 → until near the region 57 of secondary gas port → derived outdoor 58 by secondary gas port 50.
Advantages of the present invention: owing to secondary balance 39 and primary balance 32 are limited by balance location dish 34, it can only be parallel to rotation axis and make the orbiting motion of circle.After the helical coil 33 on balance with price fixing engages each other, when circle swing made by balance, price fixing and balance periphery gas can be made gradually to wriggle toward heart, make gas obtain the compression of gradual change.Main turning axle 37 and often turn over an angle, volume diminishes a unit, and pressure uprises a unit.Volume or pressure are that process is changed stepwise.Therefore, main axle 37 load in swing circle that turns is steady, the quietest when feature is for running.
The present invention uses Two-stage Compression, the vibrations that when can reduce balance motion, eccentric mass causes；It addition, turn axle realize rolling friction by main, solve the defect do not grown the service life that sliding friction in prior art brings, and need not profit oil.It addition, the present invention is in the course of the work, power is uniform, the power of piston compressor pulsation in hinge structure, thus operating is more steady, quiet.
The present invention uses Two-stage Compression, and its purpose 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, and in the course of the work, power is uniform, the pulsating force that in hinge structure, piston compressor produces, thus operating is more steady, quiet；
2, because of the eccentric swing of primary and secondary balance, arrange with axial symmetry and can balance the vibrations caused when eccentric mass reduces balance motion；
3, master turns axle and synchronization is turned wheel and realized rolling friction by fixing bearing, solves the defect do not grown the service life brought with crosshead shoe sliding friction in prior art, and is no longer necessary to use thin oil lubricant.
