Abstract
The utility model is the interior exhaust coil pipe of a kind of refrigeration compressor, there is interior exhaust coil pipe body, described interior exhaust coil pipe body is provided with exhaust buffer cavity, this exhaust buffer cavity is made up of two bell shape housings, wherein a bell shape housing forward end opening edge is along being provided with O-ring seal, seal ring and another bell shape housing are socketed, and the bottom of described two bell shape housings all has interior exhaust coil pipe attachment hole and is connected with interior exhaust coil pipe body; Described exhaust buffer cavity wall thickness and interior exhaust coil pipe wall thickness are consistent, exhaust buffer cavity length 26mm, exhaust buffer cavity internal diameter 14mm; The inside exhaust pipe insertion depth of described exhaust buffer cavity inlet end is 13-15mm, and the inside exhaust pipe insertion depth of exhaust end is 5-7mm; Do the pipe resistance of the condensation side of heat, promote the utility model, at the correct position of interior exhaust coil pipe, a silencing cavity is installed, air-flow is expanded herein further, thus reach the object reducing pneumatic noise; The utility model structure is simple, and design ingenious, low cost of manufacture, easy processing and assembling, noise reduction is remarkable.
Description
Technical field
The utility model relates to chiller plant, the interior exhaust coil pipe of especially a kind of refrigeration compressor.
Background technique
Interior exhaust coil pipe is one of key components and parts in compressor, the improvement of its structure has been become to the emphasis of each compressor manufacturer and scientific research institution's research.The exhaust coil pipe of current main flow is single isodiametric Bundy tube.Under normal circumstances, be sealed in the refrigeration agent in compressor, through the high temperature and high pressure gas that piston reciprocating type motion is formed, be transported to compressor outside by the Noise Reduction in exhaust noise silencing chamber by interior exhaust dish, enter the cooling cycle system of refrigerator.But the refrigeration agent after piston compression is the gas of High Temperature High Pressure, its flow velocity is comparatively large, and the exhaust of the intermittence of piston has gas characteristic, can cause larger pneumatic noise and compressor internal vibration.From transmission way, the pulse characteristic of air-flow outwards can transmit with two kinds of approach simultaneously.One is that intermittent pulse pneumatic enters refrigerator refrigeration system, resonates at outlet pipe place and refrigerator body.Two is that gas causes interior exhaust coil pipe to vibrate, and is delivered on refrigerator base plate, also can be delivered on refrigerator body by housing-outlet pipe-condenser tube of refrigerator by movement-stage clip-housing under-chassis.Due to the particularity of reciprocal compressor structure, its gas produced is Focal point and difficult point in the industry always.In order to reduce the noise that gas causes, a lot of engineer adopts various measures and constantly attempts and improve in the industry.As increased the length of inside exhaust pipe, for suitable internal diameter selected by coil pipe, employing has certain rigidity, is convenient to processing, has again the Bundy tube of certain elasticity coefficient simultaneously, or overlap damping spring etc. on interior exhaust coil pipe.In order to adapt to the high standard requirement of market to compressor low noise, looking for another way herein, proposing a kind of novel interior exhaust coil configuration.
Model utility content
The utility model improves for above shortcoming, provides and installs a similar buffer cavity at the correct position of interior exhaust coil pipe, air-flow is expanded herein further, thus reaches the interior exhaust coil pipe of a kind of refrigeration compressor of the object reducing pneumatic noise.
Concrete scheme of the present utility model is: the interior exhaust coil pipe of a kind of refrigeration compressor, there is interior exhaust coil pipe body, it is characterized in that: described interior exhaust coil pipe body is provided with exhaust buffer cavity, this exhaust buffer cavity is made up of two bell shape housings, wherein a bell shape housing forward end opening edge is along being provided with O-ring seal, seal ring and another bell shape housing are socketed, and the bottom of described two bell shape housings all has interior exhaust coil pipe attachment hole and is connected with interior exhaust coil pipe body.
The interior exhaust coil pipe of described a kind of refrigeration compressor, is characterized in that: described exhaust buffer cavity wall thickness and interior exhaust coil pipe wall thickness are consistent, silencing cavity length 26mm, silencing cavity internal diameter 14mm.
The interior exhaust coil pipe of described a kind of refrigeration compressor, is characterized in that: the inside exhaust pipe insertion depth of described exhaust buffer cavity inlet end is 13-15mm, and the inside exhaust pipe insertion depth of exhaust end is 5-7mm.
The utility model structure is simple, designs ingenious, installs an exhaust buffer cavity at the correct position of interior exhaust coil pipe, high temperature and high pressure gas through piston compression realizes reexpansion herein, thus reaches the object reducing exhaust gas pulses, low cost of manufacture, easy processing and assembling, noise reduction is remarkable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model silencing cavity sectional view.
In figure, exhaust coil pipe body in 1-, 2-is vented buffer cavity, 3-bell shape housing, 4-seal ring, 5-inside exhaust pipe attachment hole.
Embodiment
