Description
Technical field
The utility model relates to the baffler field in refrigeration compressor, especially a kind of air suction sound eliminator for refrigeration compressor.
Background technique
Air suction silencer is one of key components and parts of refrigeration compressor, the quality of air suction silencer is directly connected to the height of refrigeration compressor noise, therefore the optimal design research of air suction silencer has been become to the focus of each producer and research institution's concern, the air suction silencer of the refrigeration compressor of current main flow is all coupled together by each chamber in air suction silencer by connecting vessels, speed is quickly after entering baffler for refrigeration agent, in chamber, contraction and expansion can produce pneumatic noise, this is very unfavorable to reduction compressor noise, therefore significant to the optimizing research of air suction silencer, the emphasis of research is the performance muffler how promoting baffler under as far as possible not reducing the prerequisite of the performance of compressor.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above existed for air suction silencer in the market, and provide a kind of structure simple, design ingenious, volume is little, low cost of manufacture, the New Refrigerating suction muffler for compressor of good muffling effect.
Concrete scheme of the present utility model is: a kind of air suction sound eliminator for refrigeration compressor, include anechoic chamber, lower anechoic chamber and connecting vessels, connecting vessels is embedded in lower anechoic chamber, bottom, lower anechoic chamber is provided with intakeport, top, upper anechoic chamber is provided with air outlet, described connecting vessels includes upper clapboard, lower clapboard and connecting vessels main pipeline, upper clapboard is arranged on the upper end of connecting vessels main pipeline and is separated in upper anechoic chamber and lower anechoic chamber, lower clapboard and upper clapboard are mutually vertical and be distributed in the both sides of connecting vessels main pipeline, lower anechoic chamber is separated into left chamber and right chamber by lower clapboard simultaneously, the side of connecting vessels main pipeline is provided with connecting vessels suction tude, the mouth of pipe of connecting vessels suction tude and lower anechoic chamber intakeport stagger and arrange, connecting vessels main pipeline tube wall is also provided with some exhaust holes, the top of upper clapboard is provided with connecting vessels outlet, the outlet of this connecting vessels is communicated with connecting vessels main pipeline through upper clapboard.
Connecting vessels supporting post is also provided with in described connecting vessels outlet port in the utility model.
The outlet port of connecting vessels described in the utility model is also provided with one deck filter screen, and this filter screen is made up of steel sand net.
Bottom described connecting vessels main pipeline lower end and lower anechoic chamber, two oil leaking holes are respectively equipped with in the utility model.
On the tube wall of described air outlet, baffler draw-in groove is also provided with in the utility model.
The beneficial effect that the utility model obtains:
1) connecting vessels outlet port is provided with filter screen, effectively can filter out the impurity in gas, reduces gas;
2) connecting vessels main pipeline is provided with some exhaust holes, and these apertures and left anechoic chamber are connected to form secondary expansion cavity, well can reduce noise; This exhaust hole can also reduce gas simultaneously;
3) arrange because the mouth of pipe of connecting vessels suction tude and lower anechoic chamber intakeport stagger, the gas noise flowing through baffler can reduce further.
The utility model structure is simple, and design ingenious, volume is little, low cost of manufacture, good muffling effect.
