Embodiment 1

[0034] Such as figure 1 As shown, in this embodiment, a multi-suction pressure swing rotor compressor includes a cylinder rear end cover 1, a cylinder block 12, and a cylinder front end cover 11; the top and bottom ends of the cylinder block 12 are fixedly connected to the cylinder front end cover 11 and Cylinder rear end cover 1, the center of cylinder block 12 is provided with the first through hole, is provided with eccentric axle 6 in the first through hole, and one end of eccentric axle 6 is connected with the end of cylinder front end cover 11 toward cylinder block 12 rotationally, and eccentric axle The other end of 6 passes and stretches out cylinder rear end cover 1. The inner wall of the cylinder block 12 is provided with an arc groove, and the cylinder block 12 is provided with a second through hole that runs through the top and bottom ends of the cylinder block 12. The second through hole is located on the side of the arc groove away from the first through hole, an...

Embodiment 2

[0037] In this example, if figure 2 Is the schematic diagram of the eccentric wheel shaft. The end face of the eccentric shaft 6 near the front end cover 11 of the cylinder is provided with an annular suction channel 5, the suction channel 5 includes an annular channel on the outer edge of the eccentric shaft 6, is distributed inside the end face of the eccentric shaft 6 and is connected with the eccentric shaft 6. Concentric arc-shaped grooves, and straight grooves connecting the circular grooves and the arc-shaped grooves, the annular grooves are successively connected to the first-level suction hole 9, the second-level suction hole 10, and the third-level suction hole during the rotation of the eccentric wheel shaft 6. The suction holes 7 and the fourth-level suction holes 8, the first-level suction holes 9, the second-level suction holes 10, the third-level suction holes 7 and the fourth-level suction holes 8 are distributed in a circular matrix on the front end cover 11 ...

Embodiment 3

[0039] In this example, if image 3is a schematic diagram of an oscillating rotor. The end surface of the swing rotor 13 close to the front end cover 11 of the cylinder is provided with an air suction connection port 14, and the air suction connection port 4 is arranged close to the extension to ensure that the air suction connection port is always in the air suction cavity 16 and does not appear in the compression chamber. In the cavity 15, no air leakage will occur. The area on the right of the swing rotor 13 and the first through hole is the compression cavity 15 , and the area on the left of the swing rotor 13 and the first through hole is the suction cavity 16 . The rest of the content of this embodiment is the same as that disclosed in Embodiment 2.

Abstract

The invention discloses a multi-suction pressure swing rotor type compressor. The compressor comprises a cylinder rear end cover, a cylinder body and a cylinder front end cover; the two ends of the top of the cylinder body are fixedly connected with the cylinder front end cover and the cylinder rear end cover, a first through hole is formed in the center of the cylinder body, an eccentric wheel shaft is arranged in the first through hole, a swing rotor sleeves the outer side of the eccentric wheel shaft, a first-stage suction hole, a second-stage suction hole, a third-stage suction hole and afourth-stage suction hole are formed in the cylinder front end cover, a suction channel sequentially communicates with the first-stage suction hole, the second-stage suction hole, the third-stage suction hole and the fourth-stage suction hole in the rotating process, an exhaust hole is formed in the side wall of the cylinder body, and a reed valve is arranged on the exhaust hole. Compared with a device for achieving the same purpose by adopting a suction pressure adjusting valve, the swing rotor type compressor has the beneficial effects that four-stage suction is realized through the change of the mutual positions of the swing rotor, the eccentric wheel shaft and the cylinder front end cover, the energy loss is less, the structure is simpler, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a multi-suction pressure swing rotor compressor. Background technique [0002] Oscillating rotor compressors have the characteristics of being able to withstand large pressure differences and high mechanical efficiency, and are often used as compressors in refrigeration systems. In a refrigeration system with multiple evaporation temperatures at the same time, in order to allow refrigerants with different evaporation pressures to enter the compressor at the same time, it is often used to decompress the high-pressure steam through a throttling device (such as refrigerators, etc. often use this method) , so that it is consistent with the low-pressure vapor pressure and enters the compressor together. The consequence of this approach is that it causes a large throttling loss and increases energy consumption. In addition, there is another way to set up multiple compressors (suc...
