Abstract

The invention discloses a slide plate lubricating structure of a compressor. The compressor comprises a compression part and a motor part arranged in a closed housing, wherein the compression part comprises a cylinder, a piston arranged in the cylinder, a crankshaft driving the piston for eccentric rotation, a slide plate arranged in a slide plate groove of the cylinder, and a main bearing and an auxiliary bearing respectively arranged at two sides of the cylinder, and one end of the slide plate is connected with the periphery of the piston; and the motor part comprises a stator which is fixed on an inner wall of the closed housing and a rotor which is fixed on the crankshaft. The slide plate groove of the cylinder is longitudinally provided with an oil storage tank, and the main bearing is provided with an oil through hole corresponding to the oil storage tank. By reducing the oil from the end of the main bearing to mix with gaseous refrigerant, the oil is enabled to flow to and accumulate at the upper end surface of the main bearing, and then flows into the oil storage tank to lubricate the slide plate, so as to ensure lubrication effect of the slide plate under the situations of reduced oil output and low oil level. Meanwhile, based on the above structure, amount of refrigerant oil and sealed refrigerant of the compressor is reduced, and the efficiency of an air-conditioning system is improved.

Description

technical field [0001] The invention relates to a sliding vane lubricating structure of a compressor. Background technique [0002] As the price of raw materials rises and the competition in the compressor industry intensifies, it is very necessary to reduce the cost of compressors, ensure the reliability of compressors, and improve the competitiveness of products. In the compressor, there is more refrigeration oil used to lubricate the moving parts, and the cost is also higher. On the premise of ensuring the lubrication between the moving parts of the compressor and ensuring the reliability of the compressor, reducing the amount of refrigeration oil in the compressor is an effective way to reduce the manufacturing cost of the compressor. [0003] At the same time, for R290 HC refrigerant compressors, due to their flammable and explosive characteristics, the amount of refrigerant sealed in the air conditioning system is limited to a certain extent. In order to ensure its s...
