美国B.E公司生产的45-R、60-R牙轮钻机上装配的12L型、17L型回转滑片式空气压缩机和国产的YZ-35牙轮钻机上装配的HY—28/2.8型回转滑片式空气压缩机(图示),共同特点是结构简单、维修方便、耐震动、噪音小,风量、风压都能适应矿山的需要。上述几种型号空压机经过4000小时正常运转后,需要进行拆检,更换磨损零件。为了节省维修时间,保证质量,我们经过对HY-28/2.8型滑片式空压机试制、鉴定及投产,以及
The HY-28 / 2.8 type slewing slewing ring assembled on the 12-L, 17-L rotary vane air compressor assembled on a 45-R, 60-R roller cone rig manufactured by BE company and the domestic YZ-35 roller cone rig Chip air compressor (pictured), the common feature is the simple structure, easy maintenance, resistance to vibration, noise, air volume, air pressure can adapt to the needs of the mine. After several types of air compressors above 4000 hours of normal operation, the need for dismantling, replacement of wear parts. In order to save maintenance time and ensure quality, we have passed the trial manufacture, appraisal and commissioning of HY-28 / 2.8 vane air compressor, and
