Abstract
The utility model discloses a low-noise compressor body. An air exhaust cavity is formed in the body; a silencing cavity is formed in one side of the body; a circular truncated cone is arranged inside the silencing cavity; a threaded hole is formed in the circular truncated cone; an annular groove is formed by the periphery of the circular truncated cone and the inner wall of the silencing cavity; a sinking step is arranged at the upper edge of the silencing cavity; a through hole which penetrates through the silencing cavity and the air exhaust cavity is formed in the side wall of the silencing cavity. The low-noise compressor body has the advantages that according to the technical design of increasing the volume of the air exhaust cavity, the silencing cavity is added on the basis of an original air exhaust cavity and is communicated with the air exhaust cavity, and air in the air exhaust cavity is exhausted into the silencing cavity to achieve a secondary air exhaust effect, so that the exhausted air flow of a compressor is balanced, a silencing effect is achieved, the whole noise of the compressor is reduced, the compressor can steadily operate, and the efficiency is improved.
Description
Technical field
The utility model belongs to refrigeration technology field, particularly a kind of low noise compressor block.
Background technique
The form structure of traditional compressor block is unreasonable, cavity is little, cause gas flow large, make inner pressure of air cylinder lower than exhaust pressure, outlet valve cannot be opened, and available gas can not normally be discharged, and wave properties is uneven, and then produce the phenomenons such as larger noise, compressor electric motor burns, so traditional compressor has, and unstable properties, power consumption are large, the more high defect of cost of production.
Model utility content
Technical problem to be solved in the utility model is, a kind of low noise compressor block that discharge chamber volume, exhaust airstream are balanced that increases is provided.
For solving the problems of the technologies described above, a kind of low noise compressor block that the utility model provides, in described body, be provided with exhaust cavity, one side of described body is provided with silencing cavity, the inside of described silencing cavity is provided with round platform, on described round platform, has tapped hole, and the surrounding of described round platform and the inwall of silencing cavity form circular groove, the Shang Yanchu of silencing cavity is provided with the step of sinking, has the through hole that connects silencing cavity and exhaust cavity on silencing cavity sidewall.Realized the object that increases discharge chamber volume, make the exhaust airstream of compressor in silencing cavity, produce the effect of secondary exhaust, compressor air-discharging air-flow is balanced, has avoided the larger noise that causes greatly because of airflow fluctuation, tapped hole is connected for silencing cavity and bell jar.
As preferably, the opposite side of described exhaust cavity is provided with annular chamber.The overall weight that reduces compressor block, reduces production costs.
As preferably, the height of described round platform is lower than the height of silencing cavity inwall.Facilitate being connected of silencing cavity and bell jar.
Adopt after above structure, a kind of low noise compressor block of the present utility model compared with prior art, have the following advantages: the art designs of taking to strengthen discharge chamber volume, on Raw exhaust chamber, increase a silencing cavity, again silencing cavity and exhaust cavity are connected mutually, gas in exhaust cavity is drained in silencing cavity, produce the effect of secondary exhaust, so not only make compressor air-discharging air-flow be balanced, also can play the effect of noise reduction, the noise of compressor integral body is reduced, compressor operating is steady, improved efficiency, and reduced production costs.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Wherein: exhaust cavity 1, silencing cavity 2, round platform 3, tapped hole 4, circular groove 5, step 6, through hole 7, annular chamber 8.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Fig. 1～Fig. 2, a kind of low noise compressor block that the present embodiment provides, in described body, be provided with exhaust cavity 1, one side of described body is provided with silencing cavity 2, the inside of described silencing cavity 2 is provided with round platform 3, on described round platform 3, have tapped hole 4, the inwall of the surrounding of described round platform 3 and silencing cavity 2 forms circular groove 5, the height of described round platform 3 is lower than the height of silencing cavity 2 inwalls, the Shang Yanchu of silencing cavity 2 is provided with the step 6 of sinking, on silencing cavity sidewall, have the through hole 7 that connects silencing cavity 2 and exhaust cavity 1, the opposite side of described exhaust cavity 1 is provided with annular chamber 8, reduce the overall weight of compressor block.
Claims (3)
1. a low noise compressor block, in described body, be provided with exhaust cavity, it is characterized in that: a side of described body is provided with silencing cavity, the inside of described silencing cavity is provided with round platform, on described round platform, have tapped hole, the surrounding of described round platform and the inwall of silencing cavity form circular groove, and the Shang Yanchu of silencing cavity is provided with the step of sinking, have the through hole that connects silencing cavity and exhaust cavity on silencing cavity sidewall.
2. low noise compressor block according to claim 1, is characterized in that: the opposite side of described exhaust cavity is provided with annular chamber.
