Sliding vane compressors are widely used in various medium and small compressed air units and small air conditioning refrigeration units. In the chemical and food industries, oil-free machines can be used to transport or pressurize various gases. Sliding vane machinery can also be used as a vacuum pump, single stage can be 5000-4000N/m2 (vacuum 95-96%), double stage can be 1500-1OOON/m2(vacuum 98.5-99%).
Sliding vane compressors are mostly single-stage or two-stage, and more than three levels are rarely seen. Drip lubricated machine, single stage pressure ratio of 3-4; The single stage pressure ratio of the oil injection machine can reach 8; The single stage pressure ratio of oil-free lubricated machines rarely exceeds 2.5. The common displacement range is 1-20m3/min. The compressor is generally directly connected with the electric power machine, and the revolution range is generally 500-30OOrpm.
