Description
Technical Field
The utility model relates to the field of compressors, in particular to a compressor static disc variable pressure ratio exhaust port structure.
Background
When the eccentric shaft rotates clockwise, refrigerant enters the suction cavity from the suction port, and is successively sucked into crescent air cavities communicated with the suction cavity, and the crescent air cavities are closed and not communicated with the suction cavity, so that the sealed volume is gradually transferred to the center of the static disc and continuously reduced, and the gas is continuously compressed and pressure-increased, and then discharged from the static disc exhaust hole.
For scroll refrigeration compressors, over-compression and under-compression may occur under certain conditions. When the condensation temperature is too low, the exhaust pressure is lower, for example, the phenomenon that the suction-exhaust pressure ratio is too high when the gaseous refrigerant is completely compressed to the molded line head and then exhausted through the exhaust port can occur, so that the power loss of the compressor is high and the efficiency is low.
Disclosure of Invention
Aiming at the problems, the utility model aims to provide a compressor static disc transformation ratio exhaust port structure which comprises a static disc, wherein an air suction cavity is formed in the inner side of the static disc, a main exhaust hole is formed in the center of the static disc, a static vortex disc is arranged on the surface of the static disc, a through hole is formed in the static vortex disc, an advance exhaust port is further formed in the static vortex disc, the advance exhaust port is arranged in the middle of a molded line of the static vortex disc, and the advance exhaust port penetrates through the static vortex disc.
Preferably: the advance exhaust ports are provided with two groups, each group is provided with two, and every two advance exhaust ports are close together.
Preferably: the back of the static disc is provided with an oil return groove, the oil return groove and the static disc are concentrically arranged, the back of the static disc is also provided with an oil guide hole, and the oil guide hole is positioned at the inner side of the oil return groove.
Preferably: and a round hole matched with the advanced exhaust port is formed in the back of the static disc.
The utility model has the beneficial effects that:
1. still offered in the quiet gyratory disc in advance the gas vent in advance, the gas vent sets up in the molded line middle part of quiet vortex dish in advance, the gas refrigerant pushes away the discharge valve block when condensing pressure is lower, the gas vent in advance in the middle part of the molded line discharges earlier, avoid overcompression, at this moment, compare the pressure in the compression chamber with condensing pressure, when pressure has been greater than condensing pressure, the main gas vent in the middle of the rethread is discharged, the problem of compressor overcompressed is effectively alleviated, thereby reduce the idle work and the energy consumption of compressor.
2. The lubricating oil is guided to the upper part of the shell from the lower part of the shell through the oil return groove, so that the lubrication of all parts in the upper part of the shell is improved, and after the lubricating oil is guided to the upper part of the static disc from the oil return groove, the lubricating oil is guided to the compression suction cavity through the oil guide hole, so that the self-lubrication effect of the compressor is realized.
