Description
Technical field
The present invention relates to a kind of suction muffler for hermetically enclosed coolant compressor, the shell of this suction muffler has the first anechoic room of streamwise and the 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 upper part and lower part.This inserting member is fixed between part and bottom divide.Entrance is arranged in the lower part, and entrance passes into the first anechoic room by inlet channel.Have spatially, inlet channel extends into tube passage, and described tube passage forms the passage in the inserting member.Tube passage extends into again outlet passage, provides the space between tube passage and outlet passage, and described space is connected to the 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 extends to outlet passage and is connected to two anechoic rooms from the inlet channel straight line.
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 usually supports with respect to shell by spring.Shell comprises the oil sump that is used as oil storage tank, the movable part that is used for utilizing oil lubricating compressor.At certain hour during the 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 refrigerant-oil mixture.
There is the trend of making less compressor.Compressor is less, can obtain to utilize the space 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 the second anechoic room, and an end of pipe is guided through shell, and the other end passes into the first anechoic room.
Utilize this embodiment, entrance can be arranged in diverse location from the bottom side displacement of shell and with it.If for example entrance can be arranged in the upside of shell or at least in upper half part of shell, compared with the shell of entrance in lower half portion of suction muffler, suction muffler can be arranged as roughly more close oil sump.Entrance and exit then can be arranged in 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.Then suction muffler is made for " schnorkel " suction muffler.By pipe, the refrigerant gas of suction is conducted through the second anechoic room.About this point, the canal path that is used for refrigerant gas of being surrounded by pipe seals with respect to the second anechoic room, therefore can not suck the unallowed mixing between the gas in gas and the second anechoic room in the second anechoic room.In addition, not at once in the dipleg path, therefore avoid the sound transmission by pipe from the sound wave of the second anechoic room.
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 the second anechoic room.Owing to this opening, be the outside opening in annular space, namely towards the inboard of compression case, in fact the efficient of suction muffler do not affected negatively.Little opening or the hole of opening laterally are changed to minimum degree with the acoustic property of suction muffler.
Preferably, shell has the second pipe jointing part that is inwardly guided, and pipe is guided through described the 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 produces provides relatively good sealing, and this prevents that refrigerant gas from spilling into the outside from the second anechoic room.Thereby outside sound transmission also is retained as very little.
Preferably, the 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 the second pipe jointing part even can be in fact reaching inserting member on the border.The length of the second pipe jointing part is longer, and the sealing between the second pipe jointing part and the pipe realizes better.
Preferably, inserting member has pipe box, and it surrounds the second pipe jointing part at its partial-length at least.Together, pipe box and the tubular gap that circularizes, the second pipe jointing part of shell protrudes into described annular space.The internal diameter of pipe box is suitable for the external diameter of the second pipe jointing part.The internal diameter of the 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 refrigerant gas from the loss of the second anechoic room, and thereby prevents that sound wave from propagating into the outside from the second anechoic room.Further, after certain working time, a certain amount of oil will be collected between pipe box and the second pipe jointing part, and this has further improved the sealing between pipe box and the 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 relatively most length of the second pipe jointing part will be by cuff encircles.Length is larger, and it is better to seal.
Preferably, rostrum goes out to pass inserting member.The pipe that this means certain-length extends into the first anechoic room.Say that in some sense this can be used for guiding suction refrigerant gas and enters the 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 in both sides gave prominence to inserting member.DE 101 28225 C1 that this tube passage is mentioned from foreword are known.Utilize this tube passage, can set, when entering the second anechoic room from the 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 the second anechoic room.Because then the sound wave that pulsation produces can propagate into the second anechoic room, and be not penetrated into the outside.Yet, will be inhaled into coolant compressor from the refrigerant gas of the first anechoic room, and only have 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 a small amount of loss form alter course.Then this bending diapire will suck refrigerant gas guiding to tube passage and thereby along the direction that exports.
Preferably, in the first anechoic room, shell has the gas guiding wall, and its part at its circumference centers on pipe.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.
Description of drawings

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 be guided through the second anechoic room 9 and by upper part 2 to the outside.Pipe 12 from this outstanding zone of part 2, upper part has outward extending the first pipe jointing part 13, with certain internal diameter of the tolerance ground that causes, this first pipe jointing part 13 of making corresponding to the external diameter of pipe 12.
Outward extending the first pipe jointing part 13 extends inward into the second pipe jointing part 14, and the second anechoic room 9 is inwardly given prominence to and extend into to this second pipe jointing part 14 from upper part 2.The internal diameter of the second pipe jointing part 14 is corresponding to the external diameter of pipe 12.The second pipe jointing part 14 roughly extends to inserting member 7.At least, its have corresponding between inserting member 7 and the upper part 2, at the 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 the second pipe jointing part 14.In this way, between the chamber in the 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 the 12, first pipe jointing part 13, the second pipe jointing part 14 and the pipe box 15, the refrigerant gas that expectation is selected the outside from the second anechoic room 9 will be directed relatively large length, therefore guarantee relatively good tightness.As long as the refrigerant gas from the second silencing apparatus 9 can not spill into the outside, in fact, there is not the sound wave of large amplitude can spill in this way the outside.
The end of part 2 on facing, pipe box 15 has inclined-plane 16, therefore forms the doughnut with triangular cross section.By refrigerant gas carry in the second anechoic room 9 and be deposited on the second pipe jointing part 14 places spontaneously enter afterwards gap between pipe box 15 and the 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.Flow through passage 18 and because tube passage 19 accepts that the refrigerant gas of fixed-direction can enter outlet passage 17 without lossy.Space 20 is arranged between tube passage 19 and the outlet passage 17, and the pulsation in the second anechoic room 9 can be propagated by described space 20.
Described design provides a kind of simple method, guarantees: only occur by passage 18 from the transfer of the first anechoic room 8 to second anechoic rooms 9.There is not other " leakage ".
About sound, in fact the second anechoic room 9 seals along outward direction.Can exist cross section very little and length is large " leakage way ", extend in its outside along pipe 12.Yet, because this leakage way is towards outer openings, namely entering the inboard of compression case, this will be in fact have negative effect to the noise elimination character of inhaling silencer.
