Air suction silencer applied to compressor

Abstract

The invention discloses an air suction silencer applied to a compressor. An upper cover (1), a middle partition plate (4) and a shell (5) are included. A first air outlet pipe (12) and a second air outlet pipe (13) are arranged on the top of the upper cover (1). A first installing groove (14) is formed in the bottom of the upper cover (1), and a second installing groove (15) is formed in the middle inside. A first separation plate (42) is arranged in the middle partition plate (4), and a third installing groove (410) is formed in the bottom. An installing seam allowance (57) is arranged on thetop of the shell (5), and the interior is provided with a second separation plate (56). The middle partition plate (4) is arranged in the shell (5), and the third installing groove (410) is matched with the second separation plate (56). The upper cover (1) is arranged on the tops of the middle partition plate (4) and the shell (5), the first installing groove (14) is matched with the installing seam allowance (57), and the second installing groove (15) and the first separation plate (42) are matched. By means of the air suction silencer, the air conveying efficiency can be improved, oil emission is reduced, and therefore wide market prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a suction muffler applied to compressors. Background technique [0002] In the suction and exhaust structure of the current refrigerator compressor, the suction muffler has only one air outlet, and the air outlet of the muffler is pressed against the air inlet of the valve plate by buckles, and there is only a single air flow channel inside the muffler. There are two defects in this structure. One is that during the transportation of the compressor and the moment the compressor starts and stops, the movement and the shell will collide, and the buckle fixing the air outlet of the muffler is easy to loosen, causing the air outlet of the muffler to be sealed with the valve plate. If it is not strict, it will lead to the failure of the suction muffler, which will not achieve the effect of eliminating noise and reducing the suction pulsation. At the same time, it will also reduce ...

Problems solved by technology

There are two defects in this structure. One is that during the transportation of the compressor and the moment the compressor starts and stops, the movement and the casing will collide, and the buckle fixing the air outlet of the muffler is easy to loosen, resulting in the air outlet of the muffler being sealed with the valve plate. If it is not strict, it will lead to the failure of the suction muffler, which will not achieve the effect of eliminating noise and reducing the suction pulsation. At the same time, it will also reduce the suction efficiency of the compressor and reduce the cooling capacity of the compressor. In addition, the lubricant mixed in the gaseous refrigerant The oil mist will be directly sucked into the cylinder without passing through the muffler, and finally discharged from the compressor through the exhaust channel and enter the refrigeration system, which will reduce the heat exchange efficiency of the refrigeration system and increase the power consumption of the refrigeration system

The second is that there is only a single airflow channel inside the muffler, and the gaseous refrigerant coming out of the muffler is directly sucked into the cylinder. Due to the periodic characteristics of suction and exhaust when the refrigerator compressor is working, suction pulsation occurs, which reduces the suction of the compressor. gas efficiency
