摘要(Abstract):

螺杆压缩机体积小、重量轻、运行可靠。过去多为低压,现在由于风动机械效率提高和钻井深度加深需要中等排气压力的移动式风冷空压机,向中等压力发展是其本身技术发展方向之一。为适应这一发展趋向和煤矿建井钻机的具体需要,我们于1984年承担研制中压螺杆任务,1987年12月通过委级鉴定。课题研制的电机驱动移动式风冷中压螺杆压缩机型号为LGYZO/12一23/20。其主要技
After sereral years effort, we derelopped chinese first set of two-stage, oil-injected, air-cooled, and medium pressure screw compressor, the discharge pressure is more than 20 bar (2 Mpa), which had past official appraisement. This new developped compressor is specially useful to the construction of large coal pit, railway and national defence, as well as surveing, mining, clearance of pipe line, and other field where movable middle pressure compressed air source is required. This new sizn compressor can also replace same kind products which were imported. One of the new developped compressors has been working more than 900 hours during the period of industry practical test.
