Rotary compressor with pump body lubricating structure and air conditioner

Abstract

The invention relates to a rotary compressor with a pump body lubricating structure and an air conditioner with the rotary compressor. The rotary compressor with the pump body lubricating structure comprises a crankshaft, an upper cylinder, a lower cylinder, a partition plate, an upper roller, a lower roller, an upper flange, a lower flange, sliding sheet grooves, sliding sheets, reciprocating pistons, reciprocating closed cavities, one-way on-off structures and oil guide grooves. The upper cylinder and the lower cylinder are each provided with one corresponding sliding sheet groove; each sliding sheet is arranged in each corresponding sliding sheet groove and can reciprocate along each corresponding sliding groove; the upper side and the lower side of the rear end of each sliding sheet are each provided with one reciprocating piston; the reciprocating closed cavities matched with the reciprocating pistons are arranged at positions, corresponding to the reciprocating pistons, of the upper sides and lower sides the upper cylinder and the lower cylinder correspondingly; each one-way on-off structure communicates with one corresponding reciprocating closed cavity; and the upper flange, the lower flange and the partition plate are each provided with one oil guide groove communicating with the corresponding one-way on-off structure. According to the rotary compressor with the pump body lubricating structure, oil films can be formed among parts to ensure lubrication among the parts.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotary compressor with a lubricating structure for a pump body, and an air conditioner with the rotary compressor with a lubricating structure for a pump body. Background technique [0002] When the rotary compressor is running, the refrigerated oil at the bottom of the compressor supplies oil upwards through the action of the oil guide plate. Refrigerated oil enters between friction pairs such as cylinders and rollers through corresponding oil holes on the crankshaft. [0003] When the compressor is running at high load, the temperature of the pump body is high. After the cylinder and roller are heated and expanded, the height gap value will become smaller, and it is difficult to establish an oil film between adjacent parts, resulting in insufficient lubrication between friction pairs and increased wear. If the situation is improved by increasing the assembly clearance of...

Problems solved by technology

[0003] When the compressor is running at high load, the temperature of the pump body is high. After the cylinder and rollers are heated and expanded, the height gap value will become smaller, and it is difficult to establish an oil film between adjacent parts, resulting in insufficient lubrication between friction pairs and increased wear.

If the situation is improved by increasing the assembly clearance of the parts, it will lead to a decrease in the performance of the compressor
