Double-cylinder rotary type compressor component and compression device thereof

Abstract

The invention discloses a double-cylinder rotary type compressor component and a compression device thereof. The compression device comprises a first cylinder, a second cylinder and a partition plate, wherein a first compression cavity is formed in the first cylinder; a first air suction slot communicated with the first compression cavity is formed in the lower surface of the first cylinder; the second cylinder is arranged below the first cylinder; a second compression cavity is formed in the second cylinder; a second air suction slot communicated with the second compression cavity is formed in the upper surface of the second cylinder and corresponds to the first air suction slot from top to bottom; the partition plate is arranged between the first cylinder and the second cylinder; a third matching slot is formed in the partition plate and is matched with at least one of the first air suction slot and the second air suction slot; the first air suction slot, the second air suction slot and the third matching slot jointly form an air suction opening. According to the compression device for the double-cylinder rotary type compressor component, disclosed by the invention, the transverse size of the air suction opening is large, the air suction resistance is reduced, and the efficiency of the double-cylinder rotary type compressor component is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a double-cylinder rotary compressor assembly and a compression device thereof. Background technique [0002] In the related art, the suction structure of the rotary compressor is only set on the cylinder or the partition plate. Due to the limitation of the height of the cylinder and the partition plate, the suction structure cannot achieve the most suitable size, which leads to the increase of the suction resistance. , the energy efficiency is low, and the airflow pulsation is large, which affects the suction fullness of the compressor, and finally leads to the low energy efficiency of the compressor. Another kind of suction structure used on double-cylinder compressors is to open a suction port on the upper and lower cylinders respectively, and the corresponding liquid reservoir also needs two intake elbow structures. It needs to correspond one-to-one with the suction por...

[0002] In the related art, the suction structure of the rotary compressor is only set on the cylinder or the partition plate. Due to the limitation of the height of the cylinder and the partition plate, the suction structure cannot achieve the most suitable size, which leads to the increase of the suction resistance. , the energy efficiency is low, and the air flow pulsation is large, which affects the suction fullness of the compressor, and ultimately leads to the low energy efficiency of the compressor

Another kind of suction structure used on double-cylinder compressors is to open a suction port on the upper and lower cylinders respectively, and the corresponding liquid reservoir also needs two intake elbow structures. It needs to correspond one-to-one with the suction ports of the upper and lower cylinders, and the tolerance requirements are high, and the structure of the liquid receiver is complicated, which leads to an increase in the cost of the compressor and difficulty in installation. Due to the increase in the complex structure, the reliability of the compressor is reduced , also reduces the production efficiency
