Description
The present invention relates to mechanical device and household electric appliance, particularly the design proposal of air-conditioning class compressor.
In the retrieval, the technical documentation that does not have acquisition to contrast, what can contrast is known technology.Wherein, the compressor kind has single, double screw type; High-speed centrifugal; Sliding vane; Piston type; The cylinder rotator type; Eddy type.
Its deficiency is, screw compressor power is less, and the centrifugal compressor noise is bigger, and the compressor of other kind does not satisfy the motor pattern of " gyro type rotation ", so efficient is lower.
Task of the present invention is: propose a kind of design proposal, obtain at least a mode of operation that can satisfy " gyro type rotation " in view of the above, the compressor arrangement that efficient is higher overcomes the deficiency of prior art.
The closed compression machine of double rotor of the present invention can satisfy above-mentioned requirements, comprising motor, and rotating shaft, shell, supporting body is characterized in that: two rotors (1) are closed substantially in cylinder (2), and and rotating shaft, gear is integrated.
Invent further feature as described in the claim 2 to 4.
According to the compressor of invention scheme materialization, have simple in structure, easy characteristics of making, simultaneously, the rotary mode of so-called " gyro type " is satisfied in the motion of rotor, therefore, efficient is higher; Meanwhile, compressor can realize that " no oil pressure contracts " reaches " multistage compression ", and the big I of power is set arbitrarily, relates to the manufacturing of what is called " central air-conditioner " and other gas compressor, and reference value is all arranged.
Be several embodiments of the closed compressor of double rotor of the present invention below.
Fig. 1 is the structural principle sketch of the closed compressor of double rotor of the present invention.
Fig. 2 is the another kind of structural principle sketch of the closed compressor of double rotor of the present invention.
Analyze the working principle of the closed compressor of double rotor of the present invention in conjunction with Fig. 1:, replenish the known configurations that does not provide among Fig. 1 earlier for ease of understanding.Wherein, two rotors (1) and two rotating shafts, and two " diameter ", " tooth order " are identical, intermeshed gear (not providing among the figure) is integrated; Wherein, can be to have the output shaft of a rotating shaft and a motor integrated; Also can be, two rotating shafts be integrated with the output shaft of two (power is identical, counterrotating) motors, and the purpose of a kind of structure in back is apparent.
Under the prerequisite that said structure exists, analyze the working principle of the closed compressor of double rotor of the present invention again: wherein, two rotors (1) are by rotating shaft, bearing, gear " locking ", during machine operation: two rotors (1) counterrotating in cylinder (2), by rotor (1), the geometrical shape of cylinder (2), gear meshing angle decision: two rotors (1) can be substantially with the form of rolling friction, with the neutral position " Dynamic Closed " of cylinder (2), upper and lower end at cylinder (2) forms two gas channels of positive negative pressure, at this moment, gas can be exported to positive pressure side from the negative pressure end continuously with the form of " pulse pressure-charging ".
It below promptly is the basic functional principle of the closed compressor of double rotor of the present invention.In said structure, analyze as can be known, the size of positive pressure side working space is in circulation change, and is little when big immediately, at this moment, gas has " compression ", the situation of " release " produces " gas vibration " thus, and above-mentioned " gas shakes " can influence the working efficiency of compressor, for this reason, the closed compressor of double rotor of the present invention has provided solution shown in Figure 2.
Analyze its working principle in conjunction with Fig. 2, in Fig. 2, the positive pressure side gas space changes less, when having eliminated aforementioned " gas shakes ", has reduced " closed perimeter " of rotor (1) with cylinder (2), has also promptly reduced " girth " of rubbing surface.Its structure characteristic and purpose are apparent.
In above-mentioned two kinds of structures, analyze as can be known, the rotation of any rotor (1) all is " locked ", and can be understood as is " the independent existence ", has constituted the mode of operation of " gyro type rotation " described in the invention taskbar.Can set thus: by the geometrical shape of rotor (1), cylinder (2), machining accuracy decision: between two rotors (1), between rotor (1) and the cylinder (2), can be set at not closed substantially, can be according to the size of compressor horsepower (relevant) with volume, be set with the following gap of millimeter or micron order, constitute so-called " oilless compressor ".At this moment, the working condition of compressor is " not having friction ", can prolong the service life of compressor greatly.(replenish a bit, said structure does not repel mutually with " oil lubrication " programme of work, can select arbitrarily as required)
In above-mentioned " oilless compressor " structure, the backflow of gas (referring to be back to the negative pressure end from positive pressure side by the gap) has certain influence to working efficiency.Analyze as can be known, what of gas backstreaming amount are relevant with the pressure size of the positive and negative end of cylinder (2), reduce " backflow " that its pressure can reduce gas.One scheme can be: with " overlapping " cylinder (2), also be the method for " pressed and overlapped shrinking structure ", can obtain above-mentioned purpose.At this,, the positive pressure side of elementary cylinder (2) is communicated with the negative pressure end of secondary cylinder (2) by conduit ..., analogize in proper order, can address the above problem with the mode of multistage (two-stage at least) compression.Replenish at this: a kind of mode of above-mentioned " overlapping " can be to finish on the compressor of " independence "; Another kind of mode also can be by the connection of conduit, to finish on the compressor of " discrete " more than two.
In the described structure of the closed compressor of double rotor of the present invention, can adopt the mode of operation of " one-level compression, sliding friction ".At this, for reducing the work calories of compressor, one scheme can be: suction port can in position enter motor, pass through gear, enter cylinder (2), reach rotor (1), (at this, " space " being arranged in the middle of the rotor (1)) passes through cylinder (2) again to the negative pressure end.This is simple known technology, can all obtain from analyze again.
The purpose of said structure is that during compressor operating, gas can be taken away the work calories of motor, rotor (1), cylinder (2).
Full content has in sum been finished the closed compressor of double rotor of the present invention, substantially in the task described in " task " hurdle.Comprising motor, rotating shaft, shell, supporting body is characterized in that: two rotors (1) are closed substantially in cylinder (2), and and rotating shaft, gear is integrated.
Replenish a bit, the described gear of the closed compressor of double rotor of the present invention, it is little that bearing structure should satisfy sound, the precision height, the characteristics that timeliness is long, this class formation is a known technology.
In addition, rotating shaft and the mode that rotor (1) combines can be the integral structures of known " axle ", " muscle ", " cover " (" cover " refers to the working surface of rotor (1)) combination.
Replenish at last: the gas unidirectional valve; Gas-liquid separator; Overheating protection circuit; The circulation oil supply structure; Magnet absorption iron filings structure; And air-cooled, water-cooling structures etc. can be used in the closed compressor of double rotor of the present invention, and it all is known mature technology, and therefore, the present invention does not all describe.
