Abstract
The present invention discloses an air sucking silencer for compressors, which comprises an upper case, a baffle with a conducting duct, and a lower case, wherein the baffle divides the entire silencer into an upper cavity and a lower cavity; the air inlet of the conducting duct is communicated with an air inlet pipe of the lower case, the air outlet of the conducting duct is communicated with an air outlet pipe of the upper case, and rubber slices are arranged in the section of the pipeline of the conducting duct. The pipeline with the added rubber slices is equivalent to a plurality of separated small pipes in the existing silencers, so that the air sucking efficiency can be ensured, the airflow fluctuation of transmitted gases in the pipeline can be effectively decreased, and the airflow is more stable; under the condition that the original airflow loss is not affected, the noise is further decreased, and therefore, the optimum balance of the air sucking efficiency and the silencing effect can be achieved.
Description
Technical field the present invention relates to the air suction silencer that is used for the refrigeration agent transmission on the seal-type reciprocating freezer compressor.
Background technique seal-type reciprocating freezer compressor adopts crank-connecting rod-piston mechanism of motoring usually, and the use reed is air-breathing carries out the suction and the compression of refrigeration agent with outlet valve.Because air-breathing-compression process under certain frequency is not continuous, make can produce fluctuation in the refrigeration agent transmission course, cause noise.In order to reduce noise, all be provided with baffler in suction side and exhaust side.The sectional view of air suction silencer that be shown in Figure 1 at the compressor interior location.Among the figure, baffler is fixed on the cylinder head place, and the suction port of baffler steam outlet pipe and valve group is aimed at and closely is adjacent to, and the baffler sucking pipe is aimed at the suction tude of compressor housing.Existing air suction silencer has two cavity impedance formulas, two chamber bypass types or two chamber bypass to add the hybrid-type three-cavity structure of impedance usually, respectively shown in Fig. 2-1, Fig. 2-2, Fig. 2-3.In order to take into account efficient and noise, baffler inside is designed to three chambeies even the structure of multi-cavity more in the prior art, and pipeline adopts thicker diameter, whole loop lengthening, even adopt crooked pipeline (as S shape, shown in Fig. 2-4), to increase sound attenuation.Because chamber is more, also had anfractuose pipeline, like this, on making, just exist difficulty, thereby need bend pipe is divided into and be installed as one again after two bodies are made respectively.In general, the baffler of this structure can reduce loss of suction, but does not have obvious effects to reducing noise, mainly is to raise the efficiency and reduce noise to be difficult to reach balance.The more important thing is that this structure causes baffler internal structure complexity and increased manufacture cost.
Summary of the invention technical problem to be solved by this invention be to provide a kind of simple in structure, can reach the best efficient and the suction muffler for compressor of noise reduction General.
For solving the problems of the technologies described above, suction muffler for compressor of the present invention comprises upper casing, has the dividing plate and the lower casing of guiding tube, dividing plate is divided into two chambers up and down with whole baffler, the suction port of guiding tube communicates with the suction tude of lower casing, the air outlet of guiding tube and the steam outlet pipe of upper casing communicate, and described guiding tube pipeline is provided with the muscle sheet in the cross section.
Above-mentioned compressor air suction silencer, guiding tube connect by a simple circular arc communicates guiding tube suction port and lower casing suction tude.
The above-mentioned compressor air suction silencer, the suction port of described guiding tube is aimed at the suction tude of described lower casing, and the steam outlet pipe of described upper casing is aimed in the air outlet of described guiding tube.
The present invention is owing to adopted above-mentioned technical pattern, by muscle sheet (being not less than in the existing design not pipeline sectional area with the muscle sheet as long as add the pipeline sectional area of upper rib) is set in the pipeline cross section of guiding tube, like this, pipeline behind the reinforcement is equivalent to a plurality of tubules that separate in the existing baffler, can guarantee gettering efficiency, reduce the airflow fluctuation of transport gas in pipeline effectively, make gas flow more steady, under the prerequisite that does not influence original windage loss, further reduce noise.Thereby can reach the optimum balance of gettering efficiency and noise reduction.Guiding tube connects by a simple circular arc communicates guiding tube suction tude and lower casing suction tude, such correspondence can so that the loss of air-flow drop to minimum, thereby improved the working efficiency of compressor.Air suction silencer of the present invention and several are represented the air suction silencer test comparison of present advanced level, and gettering efficiency can reach better level, and the compressor overall noise reduces nearly 2dB.Air suction silencer of the present invention relatively simple for structure, air-breathing loop is shorter, thus reduced the suction superheat loss, thus reach higher gettering efficiency.Because simple in structure, the baffler cost of material is lower by 20% with baffler than typical compressor of the same type, has higher comprehensive price ratio simultaneously.The suction port of guiding tube and air outlet are aimed at the suction tude of lower casing and the steam outlet pipe of upper casing respectively, can reach minimum gas transmission loss.Riffled tube line structure of the present invention is equally applicable to the baffler of any existing structure, can further reduce noise under the prerequisite that does not influence original windage loss.
