Embodiment 1

[0035] This embodiment provides a sliding vane made of yttria stabilized tetragonal polycrystalline zirconia ceramic material, which can be used in vane compressors. The manufacturing method of the slide is:

[0036] First, a powder mixture containing zirconia and yttrium oxide is prepared and dried. In this embodiment, the ratio (molar percentage) of zirconia powder and yttrium oxide powder used for the sliding sheet is 97% to 98% zirconia, 2% to 3% yttrium oxide. Then the two powders are mixed through a ball mill.

[0037] Then, the powder mixture is sprayed and granulated, and the powder mixture is molded into the shape of a slippery sheet through an appropriate molding process. After removing the grease, the formed sliding piece is heated in a furnace at a certain temperature for a period of time to obtain a sintered sliding piece.

[0038] Finally, the above-mentioned sliding plate is finished to meet the requirements of use.

Embodiment 2

[0040] This embodiment also provides a sliding vane made of yttria stabilized tetragonal polycrystalline zirconia ceramic material, which can be used in vane compressors. The ratio of zirconia powder and yttrium oxide powder in this example is different from that in Example 1. Specifically, the manufacturing method of the slide sheet of this embodiment is:

[0041] First, a powder mixture containing zirconia and yttrium oxide is prepared and dried. In this embodiment, the ratio (mol %) of zirconia powder and yttrium oxide powder used for the sliding plate is 91% to 93% zirconia and 7% to 9% yttrium oxide. Then the two powders are mixed through a ball mill.

[0042] Then, the powder mixture is sprayed and granulated, and the powder mixture is molded into the shape of a slippery sheet through an appropriate molding process. After removing the grease, the formed sliding piece is heated in a furnace at a certain temperature for a period of time to obtain a sintered sliding piece.

Embodiment 3

[0051] This embodiment provides a sliding vane made of cerium oxide stabilized tetragonal polycrystalline zirconia toughened ceramic material, and the sliding vane can be used in a sliding vane compressor. The manufacturing method of the slide is:

[0052] First, a powder mixture containing zirconia and cerium oxide is prepared and dried. In this embodiment, the ratio (molar percentage) of the zirconia powder and the cerium oxide powder used for the sliding sheet is: 85% to 88% zirconia and 12% to 15% cerium oxide. The two powders are mixed through a ball mill.

[0053] Then, the powder mixture is sprayed and granulated, and the powder mixture is molded into the shape of a slippery sheet through an appropriate molding process. After removing the grease, the formed sliding piece is heated in a furnace at a certain temperature for a period of time to obtain a sintered sliding piece.

[0054] Finally, the above-mentioned sliding plate is finished to meet the requirements of use.

Abstract

The invention relates to a slide vane for a compressor and a slide vane compressor. The slide vane for the compressor is prepared by sintering square polycrystal zirconium oxide ceramic consisting ofzirconia and a stabilizer, wherein yttrium oxide or cerium oxide is taken as the stabilizer. The slide vane compressor is provided with the slide vane for the compressor. Compared with a conventionalsteel slide vane, the slide vane provided by the invention has high abrasion performance, and the service life of the compressor can be prolonged effectively.

Description

Technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a sliding vane for a compressor and a vane compressor using the sliding vane. Background technique [0002] In recent years, as the temperature gradually rises, the air-conditioning and refrigeration market has grown stronger. And all kinds of air-conditioning equipment, whether it is household, car, or commercial air-conditioning, are inseparable from its core component: compressor. The power consumption of compressor operation reaches more than 70% of the power consumption of the whole machine. Nowadays, the national energy conservation and environmental protection standards are increasing day by day. The index of reducing power consumption and increasing COP requires the improvement of the overall performance of the compressor. The sliding vane, as a key component inside the sliding vane compressor, has a great influence on the power consumption of the compressor. [...
