Separate partiton structure of closed compressor

Abstract

The present invention relates to the partition board structure of closed compressor. After the upper dead point and the lower dead point, in which the partition board is contacted with guide board, are connected to the connection center, the right and the left curved surfaces have different length, the suction regions are longer than the exhaust regions, and if the upper dead point is 0 deg, the lower dead point the lower dead point is in 180-360 deg referring to the direction of the first and the second guide boards. The partition board may be formed to have different functions in the right and the left curved surfaces. The present invention is superior in that the suction region is longer than the exhaust region and this results in relatively long medium gas sucking time, increased medium sucking amount and raised compressor efficiency.

Description

technical field [0001] The invention relates to a hermetic compressor, in particular to the invention of the partition plate structure of the hermetic compressor. Background technique [0002] In the structure of the guide plate compressor, the linearly moving guide plate is crimped on the curved surface of the rotating partition plate, and the partition plate divides the inner space of the cylinder into a suction area and a compression area. When the partition plate rotates, the suction zone and the compression zone are continuously switched according to the phase difference on both sides of the rotating partition plate, and the sucked and compressed fluid is discharged. [0003] Such as figure 1 As shown, the hermetic compressor of the prior art mainly consists of a motor mechanism and a compression mechanism. The electric mechanism is composed of a stator Ms and a rotor Mr, and is arranged on the inner upper part of the casing 1 for generating power; the compression mec...

Problems solved by technology

[0011] But, the dividing plate of the hermetic compressor of prior art with above-mentioned structure has following shortcoming: as image 3 and Figure 4 As shown, the phase difference between the top dead center a and the bottom dead center b is 180°(π), so that the stroke length of the discharge interval (compression interval) and the suction interval are the same. When the capacity of the compressor changes or the suction interval needs to be changed for other reasons When the diameter of the port is small, the suction volume of the medium gas will be more or less than the required amount, resulting in a decrease in the efficiency of the compressor
