Embodiment 1

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

[0036] First, a powder mixture containing zirconia and yttrium oxide is prepared and dried. In this embodiment, the ratio (mole 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] The powder mixture is then spray granulated and molded into the shape of the slide by a suitable molding process. The shaped slide is degreased and heated in a furnace at a certain temperature for a period of time to obtain a sintered slide.

[0038] Finally, the above slides are 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 a sliding vane compressor. The ratio of zirconia powder and yttrium oxide powder in this example is different from Example 1. Specifically, the slide production method of this embodiment is as follows:

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

[0042] The powder mixture is then spray granulated and molded into the shape of the slide by a suitable molding process. The shaped slide is degreased and heated in a furnace at a certain temperature for a period of time to obtain a sintered slide.

[0043] Finally, the above slides are finished to meet the requ...

Embodiment 3

[0051] This embodiment provides a sliding vane made of ceria-stabilized tetragonal polycrystalline zirconia toughened ceramic material, which can be used in a sliding vane compressor. The method of making the slide is:

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

[0053] The powder mixture is then spray granulated and molded into the shape of the slide by a suitable molding process. The shaped slide is degreased and heated in a furnace at a certain temperature for a period of time to obtain a sintered slide.

[0054] Finally, the above slides are 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 sliding vane compressor using the same. Background technique [0002] In recent years, as the temperature gradually rises, the air conditioning and refrigeration market is growing. And all kinds of air-conditioning equipment, whether it is household, car, or commercial air-conditioning, are inseparable from its core component: the compressor. The power consumption of the compressor operation reaches more than 70% of the power consumption of the whole machine. Nowadays, the national energy-saving and environmental protection standards are increasing day by day, reducing power consumption and improving COP indicators require the improvement of the overall performance of the compressor. The vane, as a key component inside the vane compressor, has a great influence on the power consumption of the compressor. [0003] For the vane ...
