摘　　要：针对MW50/28-298型氨乙炔混合气无油润滑压缩机设计缺陷导致排气量不足、使用寿命短等问题进行了理论和实验分析,在此基础上,提出了对压缩机无油润滑、活塞体结构的改造。实践证明:改造后的压缩机其微量油润滑对混合气体质量无影响,各项性能指标优越设计要求,使用寿命大大提高,这说明改造压缩机微量油润滑及活塞体结构是符合氨乙炔混合气压缩机的设计要求。We believe there are some deficiencies in the design of the MW50/28-298-type gas aetylene and amonia compressor with oil-free lubrication, for example lower air discharging capacity and short service life. Hence, we propose reforming the oil-free lubrication and piston structure of the gas aetylene and amonia compresso with theo- retical and experimental analysis. The experimental results show that a small quantity of lubrication oil contained in the compressor thus reformed has no influence on the mixed gas quality and that the reformed compressor＇s perform- ance is better than that of the existing design; thus its service life is greatly enhanced.
