Description
Technical field
The present invention relates to a kind of dividing plate interpolation pipe structure that is applied to the plastics air suction silencer of hermetically sealed compressor.
Background technique
For hermetically sealed compressor, noise is an important indicator weighing its performance always.Use the noise that produces when air suction silencer can reduce compressor air suction better, the noise of valve block being patted valve seat also can play good noise elimination effect.But then, the employing air suction silencer can increase the flow losses of refrigeration agent intakeport to a certain extent, reduces the overall performance of compressor.And the main noise frequency range that the different model compressor produces also is different.Therefore, compressor air suction silencer internal structure reasonable in design helps to improve the compressor overall performance, reduces the noise level of compressor.At present, the air suction silencer that uses at high-efficiency full-closed refrigeration compressor adopts a dividing plate and interpolation pipe that its inside is divided into two noise reduction chambers usually, to reduce noise.But along with the compressor user is more and more higher for low noise requirement, and the type of air suction silencer is also more and more, though improving, said structure can reduce noise, but all can increase the inhalation resistance of air suction silencer, reduce the complete machine performance of compressor, be difficult to satisfy simultaneously low noise and high efficiency requirement.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of dividing plate interpolation pipe structure that can take into account the suction muffler for compressor of noise reduction and efficient performance requirement simultaneously.
For solving the problems of the technologies described above, the dividing plate interpolation pipe structure of suction muffler for compressor of the present invention comprises first dividing plate, first interpolation pipe, second partition and second interpolation pipe, described first interpolation pipe and second interpolation pipe are located at respectively on described first dividing plate and the second partition, the suction port of the described first interpolation pipe lower end and the intakeport of described air suction silencer over against, the opening of described first interpolation pipe upper end and the suction port of the described second interpolation pipe lower end over against.
The above-mentioned compressor dividing plate interpolation pipe structure of air suction silencer, described first interpolation pipe is U-shaped, described second interpolation pipe is bending shape.
Above-mentioned compressor is respectively equipped with oil leaking hole with the dividing plate interpolation pipe structure of air suction silencer on described first dividing plate and the second partition.
The above-mentioned compressor dividing plate interpolation pipe structure of air suction silencer, described first dividing plate will be divided into two noise reduction chambers near the noise reduction chamber of described air suction silencer intakeport, the divergence ratio of described two noise reduction chambers is all greater than 4, and the volume of described noise reduction chamber is identical.
The present invention is owing to adopt above-mentioned technical pattern, it is divided into three noise reduction chambers with the inside of air suction silencer, three noise reduction chambers are communicated with by two interpolation pipes, the flow direction to refrigeration agent in the breathing process has played good guiding function, the generation of eddy current in the time of reducing flow of refrigerant effectively, reduce flow resistance and the pressure loss of refrigeration agent, guarantee the overall performance of compressor.First interpolation pipe will be divided into two noise reduction chambers near the noise reduction chamber of intakeport, can reduce noise on the less important frequency range of compressor more targetedly by the length of adjusting U-shaped interpolation pipe, and the noise reduction effect is better.Therefore, structure of the present invention can effectively be taken into account noise reduction and efficient performance requirement, is particularly suitable for being applied to big noise hermetically sealed compressor.

Embodiment
As shown in Figure 2, the dividing plate interpolation pipe structure of suction muffler for compressor of the present invention comprises that first dividing plate 3, first interpolation pipe 11, second partition 5 and second interpolation pipe, 12, the first interpolation pipes 11 are U-shaped (please consulting Fig. 4 simultaneously), and it is located on first dividing plate 3.Second interpolation pipe 12 is bending shape, and it is located on the second partition 5.The frequency range that the length of 11 liang of arms of first interpolation pipe is eliminated the noise according to the silencing apparatus needs is adjusted, and can accomplish to take into account the noise elimination of less important frequency range when eliminating main frequency range noise.First dividing plate 3, second partition 5 and muffler shell 6 adopt the mode of direct buckle be connected (please consulting Fig. 1 simultaneously), second partition 5 is separated into two chambers with baffler inside, and first dividing plate 3 will be divided into two noise reduction chambers 2,4 near the noise reduction chamber of intakeport 1 again.Refrigeration agent enters noise reduction chamber 2 by intakeport 1, enters noise reduction chamber 4 by the interpolation pipe 11 on the dividing plate 3 again.Since the suction port 8 of intakeport 1 and first interpolation pipe 11 over against, the opening 9 of first interpolation pipe 11 and the suction port 13 of second interpolation pipe 12 over against, so can reduce the flow losses of baffler effectively.Noise reduction chamber 2 is basic identical with the main frequency of noise elimination of noise reduction chamber 4, and less important frequency can be revised according to the length of first interpolation pipe 11, to reach best erasure effect.
As Fig. 3 and shown in Figure 5, first dividing plate 3 is provided with oil leaking hole 10, can prevent the lubricant oil deposition effectively.Also be provided with oil leaking hole on the second partition 5.
According to the noise elimination theory of simple expansion chamber silencing apparatus, the sound deadening capacity during single chamber is:
Divergence ratio in the formula
Be noise reduction chamber sectional area
With the interpolation pipe sectional area
Ratio;
It is velocity of wave;
Be the length of noise reduction chamber.
When the noise reduction chamber was divided into two noise reduction chambers: total sound deadening capacity was:
In the formula
,
Be two noise reduction chambers divergence ratios separately, ignore block board thickness, satisfy
The main frequency range of eliminating the noise
Near, when
The time,
When
The time,
Maximum, so baffler chamber of said structure, only need to guarantee that two noise reduction chambers 2 that first dividing plate 3 is divided into, 4 divergence ratio are all greater than 4, and two noise reduction chambers 2 that first dividing plate 3 is separated, 4 volume are identical as far as possible, then the acoustical absorptivity in compressor main noise frequency range is stronger, can play better noise reduction effect.
After tested, the acoustic attenuation performance of compressor air suction silencer dividing plate interpolation pipe structure of the present invention has good noise elimination effect near 900HZ, 2700HZ, taken into account the noise elimination effect of some less important frequency ranges simultaneously.Therefore, the present invention can reduce the noise level of compressor effectively under the prerequisite that guarantees the air suction silencer gettering efficiency.
