Abstract
The utility model relates to a vortex air compressor driven by direct current. The vortex air compressor driven by direct current comprises an upper cylinder, a lower cylinder, a vortex compressor set and a direct-current brushless motor set, wherein the direct-current brushless motor set is connected with a main shaft of the vortex compressor; the vortex compressor set comprises a compressing cylinder, a movable vortex disc, a static vortex disc, a self-rotation preventing mechanism, the main shaft and a support; the movable vortex disc and the static vortex disc are inserted into the compressing cylinder; the main shaft is connected with the center of the movable vortex disc; the movable vortex disc and the static vortex disc are inserted into each other by rotating relatively by180 degrees; and a certain distance is kept between the axes of the movable vortex disc and the static vortex disc. The direct-current brushless motor drives the main shaft of the vortex compressor to rotate, therefore, the movable vortex revolves and performs translational motion to complete the whole air sucking, compressing and exhausting process; the oil consumption is low; and the noise is low.
Description
Technical field
The utility model belongs to mechanical field, particularly a kind of dc powered eddy type air condition compressor.
Background technique
The car air conditioner transmission mode is mainly two kinds at present: a kind of is the dynamo belt transmission, another kind of for installing little diesel engine transmission additional.Dynamo belt transmission car air conditioner, the oil consumption height, bigger during operation of air conditioner to automobile load kind climbing influence, and can only under the state of ato unit, could move.Install little diesel engine transmission air-conditioning additional, oil consumption is higher, in the motor racing as will turn on the aircondition, needs the stagnation of movement automobile, starts little diesel engine in addition and drives, though do not influence automobile power, the oil consumption height, noise is big, fault is many, uses very inconvenient.
The model utility content
In order to address the above problem, the utility model provides a kind of dc powered eddy type air condition compressor.
The technological scheme of employing of the present utility model is: a kind of dc powered eddy type air condition compressor, comprise upper cylinder body and lower cylinder body, and comprise scroll compressor group and dc brushless motor group, described dc brushless motor group is connected with described scroll compressor main shaft.
Described scroll compressor group can comprise compression cylinder, moving scroll, fixed scroll, anti-rotation mechanism, main shaft and support, described moving scroll and described fixed scroll are installed in the described compression cylinder, described main shaft is connected with described moving scroll center, the relative Rotate 180 with described fixed scroll of described moving scroll ° is to inserting the relative certain distance in the axle center of described moving scroll and described fixed scroll.Can be provided with bearing on the described main shaft, described Bearing Installation is on described upper cylinder body.
Can be provided with anti-rotation mechanism on the described main shaft.
Described dc brushless motor group can comprise rotor, stator and power supply, and the hub of a spool spindle nose of described stator is connected with described power supply.
Described peritrochanteric can be provided with position transducer.
The beneficial effects of the utility model are: the utility model is to drive the rotation of scroll compression compressor main shaft by dc brushless motor, and to finish gas air-breathing thereby make vortex do the revolution translation, compresses and the exhaust overall process, and oil consumption is little, and noise is little.
Description of drawings
Fig. 1 is the schematic representation of dc powered eddy type air condition compressor;
The schematic representation of moving turbine of Fig. 2 and quiet turbine;
Fig. 3 is a dc brushless motor principle of rotation figure schematic representation.
Embodiment
In conjunction with Fig. 1, the utility model is divided into upper cylinder body 1 and lower cylinder body 10, mainly is made up of scroll compressor group and dc brushless motor group two-part.
Described scroll compressor group can comprise compression cylinder 9, moving vortex 8, quiet vortex 7, anti-rotation mechanism 6, main shaft 3 and support 5, described moving scroll and described fixed scroll are installed in the described compression cylinder, described main shaft is connected with described moving scroll center, the relative Rotate 180 with described fixed scroll of described moving scroll ° is to inserting the relative certain distance in the axle center of described moving scroll and described fixed scroll.Can be provided with bearing 2 on the described main shaft, described Bearing Installation is on described upper cylinder body.
In conjunction with Fig. 2, the relative Rotate 180 of the eccentric certain distance of two scroll is ° to being plugged together.Realize the multiple spot engagement between the scroll wrap on such two scroll, formed the working chamber volume of many groups crescent shape sealing; Rotation along with main shaft, formed a plurality of contact points moves continuously along scroll wrap tooth wall ecto-entad, organize crescent shape working chamber volume gradually from large to small formed more, thereby realize the cyclically-varying of sealing working chamber volume, and then realized suction, compression and the discharge of gas.The structure of moving vortex and quiet vortex is quite similar, all is made up of the scroll wrap of stretching out on end plate and the end plate, and a scroll transfixion is referred to as fixed scroll at work, and another scroll is done the revolution translation, is referred to as moving scroll.Moving vortex is under the constraint of the anti-rotation mechanism of special use, drive revolution translation (promptly do not have rotation, have only revolution), this specific assembling and motion by main shaft, make between the dynamic and static scroll wrap formed many to crescent shape sealing working chamber volume from large to small, the volume-variation of property performance period.When main shaft was in a certain angle of swing, the working chamber volume of a pair of sealing of outmost turns was opened, and breathing process begins; When main axis rotation after one week, this a pair of active chamber is closed, and forms the swept volume of sealing, and breathing process finishes; Coexist in this commentaries on classics that this new air aspiration cavity forms, the formed sealing air aspiration cavity of last commentaries on classics begins compression process simultaneously.Rotation contact points with main shaft is moved to inner ring by the outer ring, and the crescent shape working chamber volume is moved to the scroll center gradually by the outer ring of scroll, seals working chamber volume gradually from large to small, and the gas that is closed is compressed, and gas pressure raises gradually; When working chamber volume linked to each other energy with relief opening, compression process finished, and exhaust process begins.Gas in the active chamber is discharged from the relief opening that is positioned at quiet vortex central authorities, thereby finishes that gas is air-breathing, compression and exhaust overall process.
Shown in Figure 3 is the principle of rotation of dc brushless motor group, and the hub of a spool tap of motor stator 11 connects the power supply of motor, and the end points of each phase connects power tube, makes the G utmost point of power tube meet 48V during the position transducer conducting, the power tube conducting, and corresponding phase coil is energized.Owing to of the rotation of three position transducers along with rotor, meeting conducting successively, the phase coil that closes correspondingly is energising successively also, thereby the magnetic direction that stator produces also constantly changes, motor stator also and then rotates, basic principle of rotation--the position of-detection rotor of Here it is brshless DC motor switches on mutually successively to each, and the direction in the magnetic field that stator produces is changed continuously equably.The utility model is to drive the rotation of scroll compression compressor main shaft by dc brushless motor, and to finish gas air-breathing thereby make vortex do the revolution translation, compresses and the exhaust overall process.
