Description

The suction muffler that is used for hermetically enclosed coolant compressor
Technical field
The present invention relates to a kind of suction muffler that is used for hermetically enclosed coolant compressor, the shell of this suction muffler has first anechoic room of streamwise and second anechoic room of streamwise between entrance and exit, be furnished with inserting member between the anechoic room, inserting member has the anechoic room of making passage connected to one another.
Background technique
This suction muffler for example from DE 199 23 734 C2 as can be known.Shell has top and bottom.This inserting member is fixed between top and the bottom.Inlet is arranged in the bottom, and inlet feeds first anechoic room by inlet channel.Have ground, space, inlet channel extends into tube passage, and described tube passage forms the passage in the inserting member.Tube passage extends into outlet passage again, provides the space between tube passage and outlet passage, and described space is connected to second anechoic room with outlet.
From the known this embodiment of DE 101 28 225 C1.Flow path also is provided in addition herein, and it is from the inlet channel straight-line extension to outlet passage and be connected to two anechoic rooms.
This suction muffler that is used for coolant compressor has confirmed it is effective.They have reduced coolant compressor and have sucked the noise that produces owing to pressure pulse during the refrigerant gas.
Suction muffler is arranged on the cylinder head place of coolant compressor usually.Coolant compressor is arranged in the hermetically enclosed shell, and supports with respect to shell by spring usually.Shell comprises the oil sump that is used as oil storage tank, the movable part that is used to utilize oil lubricating compressor.Certain hour during compressor operation and after stopping, part of refrigerant is dissolved in the oil.Because the high pressure in the shell volume, this mixture is residual after system stops.This mixture just will separate after system stops.The vacuum that produces in the shell volume will be separated refrigeration agent from oil, this shows in the of short duration foaming of refrigeration agent-mixed oil.
There is the trend of making littler compressor.Compressor is more little, can obtain more spaces that utilize in the chiller plant (for example refrigerator or refrigerator) more.A kind of method reduced in size is to reduce the height of coolant compressor.
Yet along with reducing of compressor height, suction muffler means following risk relatively near oil sump: higher degree ground will be drawn in the suction stream of refrigeration agent from the oil of oil sump.Yet, should avoid too many oil adding in the refrigerant gas.
Summary of the invention
The present invention is based on the task of guaranteeing suction muffler is positioned at the certain degrees of freedom in the compression case.
Utilize above-mentioned suction muffler, this task is by following solution: inserting member has the pipe that is guided through second anechoic room, and an end of pipe is guided through shell, and the other end feeds first anechoic room.
Utilize this embodiment, inlet can be arranged in diverse location from the bottom side displacement of shell and with it.If for example inlet can be arranged in the upside of shell or at least in upper half part of shell, compared with the shell of inlet in lower half portion of suction muffler, suction muffler can be arranged as roughly more close oil sump.Entrance and exit can be arranged in then suction muffler identical half, for example all in upper half part, perhaps at the upside of shell.In the case, shell even can be allowed to immerse to a certain extent oil sump.Suction muffler is made for " schnorkel " suction muffler then.By pipe, the refrigerant gas of suction is conducted through second anechoic room.About this point, the canal path that is used for refrigerant gas of being surrounded by pipe seals with respect to second anechoic room, therefore can not suck the unallowed mixing between the gas in the gas and second anechoic room in second anechoic room.In addition, not at once in the dipleg path, therefore avoid sound transmission from the sound wave of second anechoic room by pipe.
Preferably, shell has the first outwards outstanding pipe jointing part, and pipe is guided through described joint.Because suction muffler is the parts of coolant compressor, coolant compressor is made in a large number, and the precision of making the parts of suction muffler only can improve to a certain extent.Therefore suppose that when pipe was guided through shell, little gap was with residual.This gap causes producing between pipe and the shell little opening, for example annular space form.If the use pipe jointing part, the axial length of this annular space will increase, so the annular space can provide the flow resistance of essence, and thereby resist sound wave and spill into stopping of the outside from second anechoic room.Owing to this opening, be the outside opening in annular space, promptly towards the inboard of compression case, in fact the efficient of suction muffler be not subjected to influencing negatively.The little opening or the hole of opening laterally are changed to minimum degree with the acoustic property of suction muffler.
Preferably, shell has second pipe jointing part that is inwardly guided, and pipe is guided through described second pipe jointing part.Thereby the sealing " path " between the pipe outside and the shell inboard is extended.The axial length of the annular space that is produced provides good relatively sealing, and this prevents that refrigerant gas from spilling into the outside from second anechoic room.Thereby outside sound transmission also is retained as very little.
Preferably, second pipe jointing part has 75% length corresponding to the minimum range in the second pipe jointing part zone between inserting member and the shell.Preferably, the length of second pipe jointing part even can be for reaching inserting member on the border in fact.The length of second pipe jointing part is long more, and the sealing between second pipe jointing part and the pipe realizes well more.
Preferably, inserting member has pipe box, and it surrounds second pipe jointing part at least on its partial-length.Together, pipe box and the tubular gap that circularizes, second pipe jointing part of shell protrudes into described annular space.The internal diameter of pipe box is suitable for the external diameter of second pipe jointing part.The internal diameter of second pipe jointing part is suitable for the external diameter of pipe, and closed tolerance is acceptable.This embodiment provides certain labyrinth sealing, and this provides and has prevented the loss of refrigerant gas from second anechoic room, and thereby prevents that sound wave from propagating into the outside from second anechoic room.Further, after certain working time, a certain amount of oil will be collected between the pipe box and second pipe jointing part, and this has further improved the sealing between the pipe box and second pipe jointing part.
Preferably, pipe box has 75% length corresponding to the minimum range in the second pipe jointing part zone between inserting member and the shell.Thereby the most relatively length of second pipe jointing part will be by cuff encircles.Length is big more, and it is good more to seal.
Preferably, rostrum goes out to pass inserting member.The pipe that this means certain-length extends into first anechoic room.Say that in some sense this can be used for guiding suction refrigerant gas and enters first anechoic room.This guiding can be used for realizing improved noise elimination character.
Preferably, the passage between the anechoic room is formed by tube passage, and this tube passage is arranged in the inserting member and gave prominence to inserting member on both sides.DE 101 28225 C1 that this tube passage is mentioned from foreword are known.Utilize this tube passage, can set, when entering second anechoic room from first anechoic room, refrigerant gas is directed.
If tube passage and outlet passage streamwise are in series arranged along same axis, are especially favourable.The space is present between tube passage and the outlet passage, and this guarantees the connection of second anechoic room.Because the sound wave that pulsation produces can propagate into second anechoic room then, and be not penetrated into the outside.Yet, will be inhaled into coolant compressor from the refrigerant gas of first anechoic room, and have only relatively little resistance.
Preferably, pipe has opening, and its crooked diapire with shell is relative.The suction refrigerant gas that flows into by pipe then can by the vortex that causes small loss form alter course.This bending diapire will suck refrigerant gas guiding then to tube passage and thereby along the direction that exports.
Preferably, in first anechoic room, shell has the gas guiding wall, and it centers on pipe on the part of its circumference.If suction muffler is mounted in its oil sump that partly immerses shell, be difficult to provide the oil export in the suction muffler.Therefore, the gas guiding wall guarantees in fact not exist hollow or recirculation regions, and greater amount oil can gather therein.On the contrary, the gas guiding wall is guaranteed will finally also take suction muffler out of by refrigerant gas by the oil that refrigerant gas sucks.Yet a small amount of oil in the suction muffler is harmless.
Preferably, crooked diapire extends into guiding surface, and it is arranged as at least in part and is parallel to this axis.If oil should be assembled, it is driven into guiding surface and from inlet passage here by refrigerant gas along diapire, so it arrives outlet.

Suction muffler 1 has band top 2 and 3 shell is divided in the bottom.Top 2 has circumferential flange 4, and it is fixed to the circumferential flange 5 that divides in the bottom, for example by connecting or welding.Between two flanges 4,5, the additional flange 6 of inserting member 7 is arranged and fixes, and it is divided into first anechoic room 8 and second anechoic room 9 with shell.The order of anechoic room 8,9 refers to the flow direction from the inlet 10 that is used for refrigeration agent to the outlet 11 that is used for refrigeration agent herein.
Top 2, bottom divide 3 and inserting member 7 make PBTP for example by the plastic material of low heat conductivity.
Inserting member 7 has pipe 12, and in this example, pipe 12 is made for one with inserting member 7.Yet pipe 12 also can otherwise be connected to inserting member 7.
Pipe 12 is guided through second anechoic room 9 and passes through top 2 to the outside.Pipe 12 from top 2 outstanding these zones, top has outward extending first pipe jointing part 13, has the external diameter of the internal diameter of tolerance ground that certain manufacturing causes, this first pipe jointing part 13 corresponding to pipe 12.
Outward extending first pipe jointing part 13 extends inward into second pipe jointing part 14, and this second pipe jointing part 14 is 2 inwardly outstanding and extend into second anechoic room 9 from top.The internal diameter of second pipe jointing part 14 is corresponding to the external diameter of pipe 12.Second pipe jointing part 14 roughly extends to inserting member 7.At least, its have corresponding between inserting member 7 and the top 2, at second pipe jointing part 14 and manage 75% length of minimum range in 12 the zone.
Inserting member 7 has the pipe box 15 that is parallel to pipe 12 extensions.The internal diameter of pipe box 15 is corresponding to the external diameter of second pipe jointing part 14.In this way, between the chamber in second anechoic room 9 and inhaling silencer 1 outside, form the labyrinth-like sealing.If in addition because the tolerance that exists, little gap can appear between pipe 12, first pipe jointing part 13, second pipe jointing part 14 and the pipe box 15, expectation will be directed big relatively length from the refrigerant gas that second anechoic room 9 escapes into the outside, therefore guarantee good relatively tightness.As long as the refrigerant gas from second silencing apparatus 9 can not spill into the outside, in fact, there is not the sound wave of large amplitude can spill into the outside in this way.
In the end in the face of top 2, pipe box 15 has inclined-plane 16, therefore forms the doughnut with triangular cross section.By refrigerant gas carry in second anechoic room 9 and be deposited on second pipe jointing part, 14 places spontaneously after enter gap between the pipe box 15 and second pipe jointing part 14, thereby further strengthen tightness.
Outlet 11 is arranged in outlet passage 17 places.Inserting member 7 has passage 18, and it is arranged in the tube passage 19.Tube passage 19 is also made one with inserting member 7.Tube passage 19 is positioned at same axis with outlet passage 17.The refrigerant gas that flows through passage 18 and accept fixed-direction owing to tube passage 19 can enter outlet passage 17 is not had lossy.Space 20 is arranged between tube passage 19 and the outlet passage 17, and the pulsation in second anechoic room 9 can be propagated by described space 20.
Extension part 21 outstanding the entering in first anechoic room of pipe 12, that is, it is extend through inserting member 7 to a certain extent.Pipe 10 has opening 22, and it is relative with crooked diapire 23.In the continuity of pipe 12, the bottom divides 3 to have gas guiding wall 24.Guided along gas guiding wall 24 by managing 12 refrigeration agents that flow into first anechoic room 8.The cross section of gas guiding wall 24 is corresponding to the part of pipe 12.The refrigerant gas 24 that is directed to crooked diapire 23 can be emitted the part oil that is included in wherein at this.Refrigerant gas drives this oil to guiding surface 25, this guiding surface 25 at least in part, be arranged as the axis that is parallel to passage 18 or tube passage 19.The refrigerant gas of flow channel 18 carries the oil from guiding surface 25 again, so it transmits on the loop.The risk that oil will be deposited on inhaling silencer 1 inboard is relatively little.
Described design provides a kind of simple method, guarantees: only take place by passage 18 from the transfer of first anechoic room, 8 to second anechoic rooms 9.There is not other " leakage ".
About sound, in fact second anechoic room 9 seals along outward direction.Can exist cross section very little and length is big " leakage way ", extend in its outside along pipe 12.Yet, because this leakage way is towards outer openings, promptly entering the inboard of compression case, this will be in fact have negative effect to the noise elimination character of inhaling silencer.
