Rotary type compressor capable of being turbocharged

Abstract

The invention provides a rotary type compressor capable of being turbocharged. The rotary type compressor comprises a closed shell, a gas-liquid separator, an exhausting pipe and a turbocharging mechanism, wherein the closed shell is internally provided with a motor assembly and a compression pump body assembly; the gas-liquid separator is communicated with a compression pump body by an air inlet elbow; the exhausting pipe is arranged at the upper end of the closed shell; the motor assembly comprises a stator and a rotor; a rotary shaft of the compressor is driven by the rotor; the compression pump body assembly comprises an upper flange, an air cylinder, a lower flange and a roller, which are mounted along the rotary shaft of the compressor in sequence; the turbocharging mechanism comprises a first transmission rod, a first transmission gear, a second transmission rod, a second transmission gear and a turbine fan blade; the first transmission rod and the rotor rotate synchronously; the first transmission gear is arranged on the first transmission rod; the second transmission rod is arranged in the closed shell by a bearing assembly; the second transmission gear and the turbine fan blade are arranged on the second transmission rod; the turbine fan blade is arranged at the air inlet end of the exhausting pipe; the first transmission gear and the second transmission gear are engaged with each other; the first transmission rod and the second transmission rod are arranged orthogonally. According to the rotary type compressor capable of being turbocharged, the flowing speed of a cold medium in circulating unit time is increased, the exhausting resistance is reduced and the performance of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a rotary compressor. Background technique [0002] Existing rotary compressors generally include a casing, a pump body, a stator, a rotor, a rotating shaft, a gas-liquid separator, a suction pipe and an exhaust pipe. When working, the rotor rotates in the stator, and drives the roller to rotate eccentrically in the cylinder through the rotating shaft. Under the eccentric rotation of the roller, the refrigerant is sucked into the cylinder and compressed until the pressure exceeds the critical pressure, and then passes through the exhaust The air pipe is output to the heat exchange system. [0003] In the air conditioning system, the refrigerant cycle relies on the suction and discharge of the compressor and the pressure difference to provide power. The flow rate of the refrigerant depends entirely on the suction and exhaust actions of the compression pump body. There is no ot...

AI Technical Summary

Problems solved by technology

[0003] In the air conditioning system, the refrigerant cycle relies on the suction and discharge of the compressor and the pressure difference to provide power. The flow rate of the refrigerant depends entirely on the suction and exhaust actions of the compression pump body. There is no other auxiliary power. The entire cycle of the air conditioning system is throttling through capillary tubes. Realizing the conversion of gaseous and liquid phases will form a large resistance to exhaust. In addition, the flow area of ​​the motor stator inside the compressor is small, which will also form a large exhaust resistance.
