一机部开封空气设备厂自行设计制造的H400离心式空气透平压缩机于一九八一年十二月试制成功。经过试车性能达到和超过了原设计要求,制气量达420公升/分,压比为6.8。压缩机用齿轮箱由开封空气设备厂和郑州机械研究所合作研制。齿轮圆周速度V=103米/秒,两个高速总轮轴转子转速分别为10800转/分和13200转/分,啮出喷油润滑。渐 The H400 Centrifugal Air Compressor, a self-designed and manufactured Havocair Air Equipment Factory, was trial-manufactured in December 1981. After the test performance to meet and exceed the original design requirements, gas production amounted to 420 liters / min, pressure ratio of 6.8. Compressor gear box by Kaifeng Air Equipment Factory and Zhengzhou Institute of Machinery developed. Gear peripheral speed V = 103 m / s, the two high-speed total hub rotor speed 10800 rev / min and 13200 rev / min, out of the injection lubrication. gradually
