Description
Technical field
The present invention relates to a kind of without oily piston compressor, particularly relate to refrigeration agent compressor.
Background technique
Compressor is the machine of pressurized gas, namely the process of air-breathing or exhaust is completed by the connecting rod of bent axle connecting band piston, bent axle realizes the to-and-fro motion of piston by motor in this process, structural characteristics due to bent axle causes the technological deficiency of at present, Heavy Weight comparatively large without oily piston compressor volume, be not suitable for the movings range such as refrigerant-recovery wide, start the occasion frequently needing portability.Without the general major failure of oily piston compressor be: 1, shaft seal is revealed; 2, piston ring is revealed; 3, bearing breaks, and the product short one side in working life that above-mentioned technical failure causes is project organization reason, is also the improper formation of materials'use on the other hand.
Chinese invention patent application numbers 201110452239.9 discloses a kind of airtight Totally-enclosed type refrigeration agent compressor, comprises and has compressor assembly and motor, and described motor comprises stator and outside rotor.Rotor is connected with the axle in the central opening being radially supported on stator interior, and this axle comprises eccentric crank pin.In order to prevent the bending load of the bearing housing of radial bearing, this compressor assembly is at least axially supported on stator at a strong point.This kind of product mainly trends towards the target reducing bearing load, not in simplified structure and the technical clarification that improves in working life.
Summary of the invention
The invention provides that a kind of structure is simple, the refrigeration agent compressor of small volume, long service life.
A kind of refrigeration agent compressor, comprise the motor being provided with main shaft, and the compressor body to be made up of the housing connected successively, cylinder body, cylinder head, Aspirating valves and outlet valve is provided with in cylinder head, described main shaft one end is connected with the eccentric wheel be located in housing, eccentric wheel side is provided with the bearing that flange connects, and cover connective pole one end, bearing periphery, the connecting rod the other end is connected with the piston ring coordinating cylinder body.The present invention passes through main shaft and the interconnective structure of connecting rod, thus greatly reduces volume and the weight of housing, simplifies apparatus structure, decreases the generation of leakage problem.
Described electric machine casing outer wall is provided with indent annulus and is connected the flange simultaneously center hole connecting eccentric wheel that is provided with through housing of main shaft of housing, center hole is provided with step hole at case inside and is connected and is provided with the positioning ring of teflon seal ring, the airtight connection main shaft of seal ring.The be connected flanged structure of housing of the indent annulus of electric machine casing outer wall makes the concise excellent in stability of compressor overall structure, ensure that the alignment of main shaft and eccentric wheel height.Utilize the gap Leakage prevention between positioning ring sealing main shaft and center hole being provided with seal ring, because seal ring has the feature of antiacid alkali resistant, anti-various organic solvent, be dissolved in all solvents hardly to have stopped that there is corrosive cold media air and corrode the leakage problem caused, simultaneously teflon has extremely low friction factor and prevents wear and leakage, realize the working life that good sealability substantially prolongs compressor, above-mentioned teflon used preferably adopts modified Teflon.Positioning ring and center hole are provided with step hole at case inside, and positioning ring is threaded with housing and realizes the tightness of positioning ring.When the seal wears in positioning ring can by unclamping the object realizing quick replaceable sealing ring with the threaded connection relation of housing, thus improve and change efficiency and extend working life.
It is ring that described connecting rod shaft holds one end; The connecting rod body of rod is provided with the pressing groove crossing with above-mentioned cirque structure and controls the screw rod of pressing groove size, control pressing groove size by screw rod and realize the fastening force that control link is connected with bearing, cirque structure and bearing due to connecting rod are annularly be connected the tightness and stability that substantially increase connection.
Eccentric wheel is provided with the screw perpendicular to main shaft, screw internal thread is connected and fixed main shaft and eccentric screw guarantees that main shaft can be with movable eccentric wheel to rotate, ensure that main shaft is connected with eccentric wheel simple and direct simultaneously, eccentric wheel leaves Screw hole structure and reduces compressor overall weight.
The piston ring that described connecting rod connects is the Piston volume tube pressing from both sides dottle pin formation between two panels piston ring, improves Piston volume tube and coordinates cylinder body tightness at work; Described piston ring material is teflon, teflon is utilized to have the feature of antiacid alkali resistant, anti-various organic solvent, prevent that there is corrosive cold media air and corrode the leakage problem caused, simultaneously teflon has extremely low friction factor and prevents wear and leakage, realize good sealability, substantially prolongs the working life of compressor.
The simple workflow of the present invention is: electric machine main shaft rotarily drives eccentric wheel and rotates, and is realized the to-and-fro motion of connecting rod by eccentric wheel, and connecting rod drives piston ring to coordinate cylinder body to realize Aspirating valves and outlet valve in cylinder head and to have worked in order gas compression work.
Refrigeration agent compressor of the present invention is interconnected main shaft and connecting rod by eccentric wheel, thus greatly reduces the weight of housing volume and compressor.
