Description
Technical field
The present invention is used for refrigeration compressor art, and the magnetic suspension particularly relating to a kind of refrigeration compressor supports.
Background technique
Refrigeration compressor many employings reciprocal compressor, reciprocal compressor belongs to positive displacement compressor, is the gas of a constant volume is sequentially sucked and discharges the compressor of enclosed space.Bent axle drivening rod in compressor, connecting rod drives piston, and piston moves reciprocatingly.Piston movement makes the working chamber volume in cylinder change, when piston is moved to inner dead point by outer dead point, inlet open, outlet valve is in closed condition, and working chamber volume increases, and air is sucked into, when piston movement is to inner dead point, suction valve cuts out, and complete intake process, working chamber volume reaches maximum; Along with bent axle continues revolution, piston is moved to outer dead point by inner dead point, and now active chamber becomes a closed volume, and intracavity gas is compressed, and reaches exhaust pressure, completes compression process; Then outlet valve is opened, and work intracavity gas is fully drained cylinder, completes exhaust process.
Reciprocal compressor is used for the refrigerating fields such as refrigerator.By the running of motor, drive crankshaft & connecting to promote reciprocating motion of the pistons, complete air-breathing, compression, exhaust, expansion Four processes.The motion of connecting rod can be regarded connnecting rod big end as and rotate together with crank pin (crankshaft eccentric shaft), and connecting rod small end is reciprocating together with wrist pin.The motion of these parts above-mentioned all completes on the movement of compressor, and this makes movement can produce comparatively big bang when compressor operating, and vibrations can cause the resonance of refrigerator system pipeline by shell, therefore pipeline is easily ruptured, in addition, vibrations also bring out noise, cause noise to exceed standard.In order to reduce the transmission of vibrations, being everlasting and between housing and movement, stage clip being set and being cushioned the vibrations of movement by stage clip, thus reaching the effect of shell damping.But stage clip itself is metalwork, the vibrations of movement can be delivered to housing easily by stage clip body, and the bang path namely shaken is not blocked completely, so the structure adopting stage clip to cushion movement vibrations can not reach perfect damping effect.
Summary of the invention
For solving the problem, the invention provides one and blocking vibrations bang path completely, the refrigeration compressor magnetic suspension reaching perfect damping effect supports.
The technical solution adopted for the present invention to solve the technical problems is: a kind of magnetic suspension of refrigeration compressor supports, comprise the upper magnet be located on the downside of movement and the lower magnet be located at inside lower casing, upper magnet and lower magnet homopolarity are just to setting, and movement is suspended in the top of lower casing.
Be further used as the improvement of technical solution of the present invention, the downside of movement is evenly provided with some screws, and the head of each screw is equipped with the first caulking groove installing magnet.
Be further used as the improvement of technical solution of the present invention, upper magnet is be arranged on a monoblock in the first caulking groove or polylith.
Be further used as the improvement of technical solution of the present invention, the inner side of lower casing is provided with the supporting element of some fixing lower magnets, and the lower end of supporting element is fixedly connected with lower casing and is provided with the second caulking groove installing lower magnet in upper end.
Be further used as the improvement of technical solution of the present invention, lower magnet is be arranged on a monoblock in the second caulking groove or polylith.
Be further used as the improvement of technical solution of the present invention, also comprise and be located at the second lower magnet on the upside of movement and be located at magnet on second inside upper casing, on the second lower magnet and second, magnet heteropole is just to setting.
Beneficial effect of the present invention: the magnetic suspension of this refrigeration compressor supports; with the mutual repulsive force of interpolar, movement is suspended in above lower casing by upper magnet and lower magnet; movement is separated completely with lower casing; do not have directly or by the mediate contact of stage clip between movement and shell; namely the bang path shaken is blocked completely, thus vibrations when movement is worked cannot be delivered to the outside of refrigeration compressor, reach perfect damping effect; final protection external equipment safety, reduces noise pollution.
