Abstract

The invention relates to a stationary disc, in particular to a stationary disc for a scroll type compressor, and belongs to the technical field of alloy materials. The stationary disc is made of an aluminum alloy material, and the aluminum alloy material comprises, by mass, 6-8% of Si, 0.10-0.15% of Fe, 0.5-0.7% of Mg, 0.01-0.02% of Zr, 0.01-0.15% of Ti, 0.03-0.04% of B, 0.02-0.05% of La, and thebalance aluminum and unavoidable impurities. The aluminum alloy material used in the stationary disc is reasonably configured, and meanwhile, a specific preparation method is adopted, so that the obtained stationary disc has higher strength and higher corrosion resistance.

Description

Technical field [0001] The invention relates to a static plate, in particular to a static plate for a scroll compressor, and belongs to the technical field of alloy materials. technical background [0002] The scroll compressor is an energy-saving compressor in the world today. Because of its stable operation, low vibration and quiet working environment, it is also known as the "super static compressor". The scroll compressor has the advantages of novel and precise structure, small size, low noise, light weight, low vibration, low energy consumption, long life, continuous and stable gas transmission, reliable operation, clean air source, etc. It is known as the "new revolution" "Compressor" and "Compressor without maintenance". Scroll compressors are an ideal power source for pneumatic machinery and are widely used in industries such as industry, agriculture, transportation, medical equipment, food decoration and prevention, and other occasions that require compressed air.
