Ceramic sliding vane used for rotary vane type compressor and preparation method thereof

Abstract

The invention provides a ceramic sliding vane used for a rotary vane type compressor and a preparation method thereof. The ceramic sliding vane comprises following components by weight: 90-99.9% of Al2O3 powder, 0.1-10% of Y2O3 powder, 0-1% of SiO2 powder, 0-1% of CeO2 powder, 0-1% of LiO2 powder and 0-1% of MOS2 powder, with the average particle size of the components being not more than 100 nm. The ceramic sliding vane is used for a sealed rotary compressor, and can obtain good wear resistance and reduce wear and friction loss between the ceramic sliding vane and a cooperated air cylinder or a rolling piston of the sealed rotary compressor. The ceramic sliding vane has good heat insulation, and increases the heat exchange efficiency of an air conditioner.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a ceramic sliding vane for a rotary vane compressor and a preparation method thereof. Background technique [0002] The air-conditioning and refrigeration market is huge, including automobile air-conditioning, household air-conditioning and various refrigeration equipment. The key equipment is the compressor, and the compressor is its heart. The quality and energy saving of the compressor are the key technologies of air-conditioning and refrigeration equipment. It is precisely the key component of the compressor. [0003] It is usually used in sealed rotary compressors for household appliances such as air conditioners and refrigerators. The sealed rotary compressor includes eccentric parts and rolling pistons. The outer peripheral surface of the eccentric parts is equipped with rolling pistons. The motor drives the rolling pistons to rotate through the eccentric parts. The r...

AI Technical Summary

Problems solved by technology

[0005] 1) The service life of compressors for refrigeration and air conditioning is required to be about 10 years, and the wear resistance of metal materials is not ideal. After long-term wear, metal chips will fall from the top of the sliding vane, and the metal chips will get stuck in the compressor and cause compression. The machine burns out, causing damage to the compressor

[0006] 2) Refrigeration works uninterruptedly. The compressor and its sliding vanes are important core components of the air conditioner. Years of work have caused serious loss of sliding vanes;

[0007] 3) The metal slide has high thermal conductivity, and the heat insulation performance of the metal slide is not good, which reduces the heat exchange efficiency of the air conditioner

[0008] The market has higher and higher requirements for compressor quality stability and energy saving. The development of new materials has attracted people's attention. High-tech ceramic materials are wear-resistant, heat-insulating, and light in weight. They are ideal materials for sliding vanes. Traditional ceramics are brittle and safe. High-tech ceramics with low resistance and high toughness are the future trend of slide material
