Abstract
The present invention relates to a kind of compressor, on its can 1 the direct-type suction pipe is arranged.For this reason, suction pipe 8 is extended to motor-compressor set 2 from casing wall 1.In order to improve the efficient of compressor, be enclosed within certain intervals outside the suction pipe with adiabatic overcoat 19, make the gas that enters suction pipe be heated to inferior limit.Spiral spring piece 15 or sleeve pipe that suction pipe is preferably soft.Overcoat 19 can be a plastic bushing, and its end is fixed.
Description
The present invention relates to a kind of compressor, it comprises Packed shell, can hold the motor-compressor device, and the inlet of this device has link.Inlet on the casing wall is equipped with link, and this link is connected by suction pipe.
This compressor has been known to the public from Deutsches Reichs-Patent specification DE-PS2650937.Made tens kinds of compressors with can, wherein suction pipe stretches in the shell from vaporizer.The motor-compressor device draws the refrigerant of having vaporized from the space in the shell.People know that also suction pipe is passed direct linking to each other with the motor-compressor device of casing wall can improve its efficient.This direct suction pipe lowers compression temperature, thereby has reduced the burned possibility of entrained oil.For this connection between casing wall and the device, one of them requirement is that this pipe must be " sewing ".Otherwise the pressure in the can be lower than (when refrigerant is absorbed by oil) or be higher than pressure in the vaporizer-compressor loop of sealing.Should avoid higher pressure in the shell, because will produce additional noise at each bearing place.
Above-mentioned Deutsches Reichs-Patent specification DE-PS recommends some direct suction-pipe structure.It has adopted especially and has had the accurate sealing annulation of selecting of sewing passage.The deficiency of sealing annulation be they after long-time running, be subjected to the influence of refrigerant and oil, can expand so that hardening.This causes producing additional noise and causes that connecting tube no longer is " sewing ".Other structures that above-mentioned Deutsches Reichs-Patent specification is recommended are to adopt the ball formula sealing of sliding.These structures are firmer, may pass to shell to most vibration, and it has also caused additional noise.And this structure is very expensive.
European patent application EP 0,073,469 reasonable this problems that solved, it has adopted the soft suction pipe of the cylindrical helical spring spare form of tight coiling to be used as direct suction pipe, this part in addition can not transmit contact noise rapidly, its enough " sewing " keeps stable so that pressure to be provided, but seepage within reason so that colder refrigerant can be from the spaces that suction pipe flows in the shell and the back side is relatively warmer, and the gas that returns in this case is relatively warmer.
The objective of the invention is to propose a kind of more effectively direct suction type compressor.
For this reason, the invention is characterized in this suction pipe surrounded by adiabatic overcoat, overcoat and suction pipe have certain intervals.Insulating coating stops gas and the interior gas of shell in the suction pipe to exchange, and the gas that makes into only is heated to bottom line.Air pulsing when in addition, overcoat has weakened gas and flows into the inner space of compressor case.
An embodiment of compressor it is characterized in that an end of overcoat is fixed on the link, and the other end is directly downward, leaves the spatial communication in suction pipe and the compressor case.
Overcoat has certain distance around the suction pipe, makes device starting or when stopping, overcoat can not be collided with suction pipe.Jacket bottom should be opened wide, and makes superfluous oil droplet return in the compressor case.
Another embodiment of compressor is characterised in that overcoat constitutes with soft porous materials.For example braided metal net or plastic bushing.
Below will be by way of example and with reference to accompanying drawing, describe one embodiment of the present of invention in detail.Wherein:
Fig. 1 is the side cross-sectional schematic of compressor;
Fig. 2 has represented the soft suction pipe of the compressor that constitutes with spiral spring piece shown in Figure 1, and centering on it on has overcoat.
Compressor includes can 1, with spring 3 motor-compressor device 2 is hung in it, and this device includes motor 4 and suction pump 5.Motor connecting rod 6 driven plunger 7, the refrigerant of vaporization is inhaled in the pump by the suction pipe 8 that links to each other with silencing apparatus with link 14, and being contractd by pump pressure is pressed in the refrigeration system (not shown) by pressure tube 9.Oil groove 10 is positioned at outer casing bottom.On the passage 11 of shell link 12 is housed.Link 14 is equipped with at inlet 13 places of the suction pump on the motor-compressor device 2.Suction pipe 8 is connected between two links 12,14.Suction pipe is soft, and its form is the cylindrically coiled spring spare 15 with tight coiling circle 16.In one embodiment, there is adiabatic overcoat 19 firmly to be connected on the link 14.This overcoat does not contact with spiral spring piece 15.The external diameter that the internal diameter of overcoat cans be compared to spiral spring piece most is big 3 to 5 millimeters.More gratifying spring part is that its thickness is 0.8 to 1.0 millimeter, and the width of circle is approximately 20 millimeters, and length is approximately 50 millimeters, and circle is 0.05 to 0.15 millimeter with the circle spacing.This spiral spring piece allows that the motor-compressor device moves with respect to shell, can not transmit sound vibration rapidly, and owing between circle and the circle narrow and small gap is arranged, and suction pipe fills is permitted gas and oil is sewed slightly.Overcoat plays the thermal insulation effect, and the air pulsing when weakening gas flow compressor case inner space.
The refrigeration system that is connected with compressor often includes some oil of carrying secretly out in the compressor case.These oil precipitate between spiral spring piece circle and circle, like this refrigerant steam are also played some seal actions.Its attendant advantages is that oil is got rid of in helical spring vibration meeting when device starts or stops, and the amplitude of vibration is still bigger.Like this, superfluous oil is discharged in the overcoat, and the space that the bottom by overcoat flows in the shell is gone.Therefore, do not need oil separator in addition, go in the gap between this structure also prevents circle that the oil in the compressor case is splashed to spiral spring piece and encloses.
In order to allow the bigger displacement between compressor set and the shell, it is favourable that the end 17,18 of spiral spring piece is set to link 12,14 the preceding paragraph length.Link 12,14 is preferably made with the poor conductor of heat.Its result significantly reduces the heat that is transferred on the spiral spring piece and passes to the heat of refrigerant thus.
Soft sleeve pipe for example has the braided sleeving of certain strength, can replace spiral spring piece to make suction pipe.The hole of braided sleeving should be too not big.This sleeve pipe also can meet the demands and have the advantage identical with spiral spring piece.
Overcoat can be replaced with the sleeve pipe that soft porous materials is made.This sleeve pipe can be with certain interval around whole suction pipe, and its two ends are fixed to corresponding link and get on.Flexible sleeve moves with respect to shell along with installing in the mode identical with soft suction pipe.Still to provide the suitable interval size in the overcoat.
