Description
Technical Field
The invention belongs to the technical field of accessories of refrigeration compressors, and particularly relates to a combined type air suction and exhaust silencer for a refrigeration compressor.
Background
The above-described combined suction and discharge muffler for a refrigeration compressor may also be referred to as a "combined refrigeration compressor suction and discharge muffler" (hereinafter referred to as "combined refrigeration compressor suction and discharge muffler"). As is known in the art, a suction muffler and a discharge muffler are respectively fitted on a reciprocating hermetic refrigeration compressor (generally on a cylinder block) and at different positions, i.e. at different positions of the cylinder block, in particular, the suction muffler is fitted with the refrigeration compressor intake cavity mouth of the refrigeration compressor (i.e. the intake port on the aforesaid cylinder block) and the discharge muffler is fitted with the refrigeration compressor discharge cavity mouth of the refrigeration compressor (i.e. the aforesaid discharge port on the cylinder block).
Further, as known in the art, when the refrigeration compressor works, the air cylinder sucks refrigerant gas through the suction muffler, and the suction muffler not only plays a role in weakening the heating effect on the refrigerant when the interior of the compressor generates heat, but also plays a role in reducing noise and vibration caused by pressure pulsation in the flowing process of the refrigerant gas, thereby being beneficial to reducing the operation noise of the compressor, and simultaneously being capable of effectively improving the working efficiency of the compressor, namely improving the energy efficiency ratio (COP) of the refrigeration compressor. It follows that the suction muffler is now an essential and one of the more important accessories of reciprocating hermetic refrigeration compressors; as is also known in the art, the cylinders discharge gas through the exhaust muffler and are acted upon by the exhaust muffler to reduce exhaust noise as the compressor exhaust noise is a significant source of overall noise. It follows that the exhaust muffler is also an essential and important accessory for the reciprocating hermetic refrigeration compressor at present.
Technical information about a suction muffler of a refrigeration compressor is not lacking in the published chinese patent literature, and examples thereof include CN2663663Y (muffler case), CN2705629Y (muffler), CN2733037Y (totally enclosed refrigeration compressor suction muffler), CN2833127Y (totally enclosed refrigeration compressor novel energy-saving muffler), CN2886124Y (refrigeration compressor semi-direct suction muffler), CN201165957Y (refrigeration compressor suction muffler), CN101487461B (fitting structure of a case cover of a refrigeration compressor suction muffler and a case), CN101545472B (refrigeration compressor suction muffler), and CN101545473B (refrigeration compressor suction muffler), and the like.
Technical information about the exhaust silencer of the refrigeration compressor is also not lacking in the published chinese patent literature, such as CN104763612a (an exhaust silencer and a refrigeration compressor), CN105065231a (a refrigeration compressor having an exhaust silencer structure), CN205260254U (an exhaust silencer for a compressor) and CN206770156U (an exhaust silencer for a refrigeration compressor and a refrigeration compressor), and the like.
The reading of the patent documents cited above is not limited to: the suction muffler and the discharge muffler are independent structures independent of each other, and they are designed as independent structures independent of each other because they are considered based on the following factors: firstly, the air inlet cavity opening and the air outlet cavity opening are arranged at different positions on the cylinder seat of the refrigeration compressor; and secondly, because of the fact that a great temperature difference factor exists between an air suction system and an air discharge system of the refrigeration compressor, namely the temperature of the air discharge system is obviously higher than that of the air suction system, if an air inlet cavity opening and an air discharge cavity opening of the refrigeration compressor are designed at reasonable positions in the same area, although the processing difficulty of a cylinder seat can be reduced, the processing efficiency can be improved, and even the processing cost can be saved, heat can be transferred to the air suction silencer in the process that high-temperature gas discharged by the air discharge system passes through the air discharge silencer and is discharged by the air discharge silencer, so that the temperature of the air in the inner cavity of the refrigeration compressor is increased, the efficiency of the refrigeration compressor is improved, and the expected service life of the refrigeration compressor is finally damaged. Therefore, the structural design is not a fair list, and in the surface view, the intake and exhaust cavity openings on the cylinder seat are positioned at different positions, so that the intake and exhaust silencers can only be passively designed into independent structures, or the intake and exhaust cavity openings can only be positioned at different positions in order to avoid the exhaust silencers from transmitting heat to the intake silencer due to large intake and exhaust temperature difference. Since the aforementioned causal relationship has long been accepted and accepted by the industry, technical information of combining the suction muffler and the discharge muffler with each other is not known in the middle-outer patent and non-patent documents disclosed so far, and the situation that the inlet and the discharge chamber openings on the cylinder seat of the refrigeration compressor are kept in different positions, namely in different areas all the time is caused, that is, the structural design of the suction muffler and the discharge muffler does not play a positive role in optimizing the design of the cylinder seat of the refrigeration compressor.
In addition, forming the suction muffler and the exhaust muffler as separate components has at least the following drawbacks: firstly, because the air suction silencer is provided with an air suction silencer air outlet which is matched with an air inlet cavity opening on the cylinder seat, and because the exhaust silencer is provided with an exhaust silencer air inlet which is matched with an air outlet cavity opening on the cylinder seat, the matching parts are more, the probability of air leakage is relatively high, the efficiency of the refrigeration compressor can be influenced once the air leakage is generated, and the noise can be increased; secondly, because the air inlet silencer and the air outlet silencer are respectively independent structures, on one hand, the cost is increased because of the need of manufacturing the air inlet silencer and the air outlet silencer respectively, and on the other hand, the material consumption is large, so that the resource saving is not facilitated; thirdly, because the air inlet silencer and the air outlet silencer are independent components, the installation time is long, and the labor cost is not saved; fourth, the large amount of the mold requires significantly higher manufacturing costs.
The applicant has made long-lasting and beneficial searches and has carried out a non-limited number of tests with respect to the prior art described above, which eventually lead to the solutions described below.

A sealing ring 25 is provided on the sealing boss 212, and the sealing ring 25 has a sealing ring cavity 251, and the sealing ring cavity 251 is matched with the sealing boss step ring 2121, and the exhaust muffler chamber partition 231 and the pipe joint 243 are matched with the sealing ring cavity 251 in a sealing manner.
In this embodiment, the lower end of the aforementioned drip tube 22 is fixed to the drip tube support provided on the refrigeration compressor in the use state, and the drip tube 22 can be adjusted upward or downward as required, and when adjusted upward, it is close to the lower end face of the shunt tube 232, and vice versa.
It can be determined without doubt by the applicant's description above: the intake and exhaust ports are formed in the same area in the cylinder block of the refrigeration compressor and are controlled by valves (not shown). In the use state, the fixing lug 36 of the cylinder air inlet and outlet matching seat 3 is fixed with the fixing position on the cylinder seat at the position corresponding to the fixing lug fixing screw hole 361 by using a screw, the matching seat air outlet cavity 31 corresponds to and is matched with the air inlet cavity opening on the cylinder seat, and the matching seat air inlet cavity 32 corresponds to and is matched with the air outlet cavity opening on the cylinder seat.
In the working state of the refrigeration compressor, gas is sucked from the suction nozzle 12 of the suction muffler assembly 1, sequentially passes through the suction nozzle connecting pipe cavity of the suction nozzle connecting pipe 121, the first suction muffler cavity 111 (the part positioned at the left side of the longitudinal partition 131), the horizontal partition dividing joint hole 13211 of the horizontal partition dividing joint 1321, the upper pipe connecting muffler cavity 1421, the first suction muffler cavity 111 and the matching seat air inlet hole 34, enters the matching seat air outlet cavity 31, and is introduced into the refrigeration compressor through the air inlet cavity opening on the cylinder seat by the matching seat air outlet cavity 31. In this process, oil droplets are dropped through the oil dropping hole 11111 on the suction muffler chamber bottom plate 1111 of the first suction muffler chamber 111, specifically indicated by a broken-line arrow (gas is indicated by a solid-line arrow) marked in fig. 2. The gas self-priming nozzle connecting pipe 121 is introduced into the air inlet 134 of the matching seat, and the gas is split and has an inflection point in the process of being introduced into the air outlet cavity 31 of the matching seat through the air inlet 134 of the matching seat, so that the gas self-priming nozzle has an ideal silencing effect. For example, when the horizontal separator split joint hole 13211 introduces the gas into the upper pipe joint silencing chamber 1421, a part of the gas is split through the vertical separator split joint hole 13111, and the two gas paths collide when entering the second suction silencing chamber 141, thereby reducing noise.
The high temperature gas in the refrigeration compressor is discharged through the coupling seat gas inlet chamber 32, the coupling seat gas outlet hole 35, the gas inlet connection pipe 242 (also referred to as "gas outlet connection pipe") with respect to the second gas outlet muffler pipe 24, the second gas outlet muffler chamber 242, the gas outlet muffler chamber partition plate exhaust hole 2311, the first gas outlet muffler chamber 211, the oil dropping chamber 2112 formed on the bottom wall of the first gas outlet muffler chamber 211, and the oil dropping pipe 22 in this order. In the foregoing process, since the lower end of the shunt tube 232 is provided with the shunt hole 2322, the gas in the first exhaust silencing cavity 211 is divided into two paths, one path of gas enters the drip tube 22 in diameter, and the other path of gas enters the drip tube 22 after passing through the shunt hole 2322 and the shunt tube cavity 2321 in sequence, so that a good noise reduction effect is achieved.
In addition, according to common practice, when the suction muffler inlet is in close proximity to the compressor housing inlet, then air is sucked in; when a certain distance exists between the air inlet of the air suction silencer and the compressor shell and the air inlet of the compressor shell is provided with a special pipeline, then the air in the compressor is sucked and mixed with oil gas; when there is a distance between the suction muffler inlet and the compressor housing and there is no dedicated conduit for the compressor housing inlet, then the suction is a mixture of air and oil and gas mixed inside the compressor. Since the three aforementioned cases are related only to the installation position of the suction muffler, the present invention can cope with the three aforementioned installation modes.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
