Problems solved by technology
[0002] It is pointed out in the related art that a rotary compressor houses a motor and a compression mechanism in an airtight container. Due to the compression of the compression mechanism, the temperature of the refrigerant becomes higher. Low, high-temperature gas transfers heat to the low-temperature refrigerant in the suction chamber through the upper and lower bearings and the cylinder, causing the refrigerant sucked into the suction chamber to heat and expand, and the pressure rises
In the end, the amount of refrigerant inhaled in the next working cycle of the same working volume will decrease, resulting in a decrease in the volumetric efficiency and performance of the compressor.

The invention discloses a rotary compressor. The rotary compressor comprises a housing, a compression mechanism and a crankshaft, wherein an oil pool is arranged in the housing; the compression mechanism is arranged in the housing, the compression mechanism comprises a gas suction hole, the compression mechanism comprises a cylinder, a main bearing and an auxiliary bearing, the cylinder comprises a gas suction cavity communicated with the gas suction hole, the main bearing is arranged at the top of the cylinder and the auxiliary bearing is arranged at the bottom of the cylinder; and the crankshaft penetrates through the compression mechanism, the crankshaft comprises an oil guide channel, the oil guide channel is communicated with the oil pool, a heat insulation cavity is formed on one side of the compression mechanism, which is close to the gas suction cavity, and the heat insulation cavity is communicated with the oil guide channel and the oil pool, so that lubricating oil in the oil pool can flow between the oil pool and the heat insulation cavity in a circulating manner. According to the rotary compressor disclosed by the invention, temperature rise and expansion of a refrigerant in the gas suction cavity can be inhibited, the gas suction amount of the gas suction cavity is improved, the volumetric efficiency of the rotary compressor is further improved and the performances of the rotary compressor are upgraded.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a rotary compressor. Background technique [0002] It is pointed out in the related art that a rotary compressor houses a motor and a compression mechanism in an airtight container. The temperature of the refrigerant increases due to the compression of the compression mechanism. Lower, the high-temperature gas transfers heat to the low-temperature refrigerant in the suction chamber through the upper and lower bearings and the cylinder, causing the refrigerant sucked into the suction chamber to heat and expand, and the pressure rises. In the end, the amount of refrigerant inhaled in the next working cycle of the same working volume will be reduced, resulting in a decrease in the volumetric efficiency and performance of the compressor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. T...
