Problems solved by technology

Equally, this compressor is also only provided with an exhaust hole on the upper and lower covers respectively, and there is no exhaust hole on the intermediate partition of the compressor pump body, and the intermediate partition does not have an exhaust function, which makes it impossible to The lower end surface of the upper cylinder and the upper end surface of the lower cylinder are designed with exhaust ports. The compressed high-temperature and high-pressure gas still has only two exhaust channels: the upper exhaust at the upper cover and the lower exhaust at the lower cover. There is also compressor exhaust resistance. The problem of large size and low efficiency of the whole machine

Abstract

The invention discloses a rotate dual-cylinder compressor adopted with a exhaust intermediate baffle plate. The compressor is a normal rotate dual-cylinder compressor with it intermediate baffle plate additionally set a valve base slot on which set exhaust port, exhaust fin and other components and a concave cavity acquiring exhausting function for the baffle plate. In this way the compressor exhausting resistance is alleviated so the whole efficiency is enhanced. Moreover in consequence that two eccentric radius is arranged on two side of the eccentric shaft with a angle of 180 degrees, the lower exhaustion and the upper exhaustion are just opposite when in the baffle plate with a phase angle difference of 180 degrees, the crest and the hollow of the exhaustion pulsing lapping over so to reduce the exhausting noise. The experiment shows that 5HP rotate dual-cylinder compressor adopted with this invention has a 4 percents higher efficiency and a 5 to 6 dB lower noise than the normal one.

Description

technical field [0001] The invention relates to a compressor, especially a rotary double-cylinder compressor which can significantly reduce exhaust resistance, improve compressor efficiency and significantly improve noise. Background technique [0002] Conventional rotary twin-cylinder compressors (see figure 1 ) consists of a closed container with a certain amount of lubricating oil at the bottom of the container to lubricate the sliding parts of the pump body. The pump body of the compressor mainly includes components such as upper and lower rotors, upper and lower cylinders, eccentric shafts, upper covers, lower covers, sliding vanes, springs and middle partitions. The main working process of the compressor is: the rotor rotates eccentrically in the cylinder, the middle partition divides the upper and lower cylinders into two working chambers, and the upper and lower slides are in close contact with the upper and lower rotors under the action of springs, respectively sep...
