通过对在生产中与各种清洗气体系统同时使用的1Г-266/320和2ШЛК-1420型氮氢气压缩机[1]的工作进行调查,发现以稀薄氮气对气体进行催化方式的清洗后,压缩机的高压系列极易导致偏心。由于偏心或活塞支承面与摩擦面的不均衡贴合,产生了不显著的局部过载,后者则导致负载情况下温度的增高、润滑的恶化（油粘度急剧降低,发生干摩擦而金属和金属相咬）和活塞环、巴比特合金浇涂层、衬套和其他零件的极度磨损。
By investigating the operation of 1R-266/320 and 2R-K-1420 Nitrogen Hydrogen Compressors [1], which are used in conjunction with various purge gas systems in production, it was found that after purging the gas catalytically with a thin nitrogen gas, the compression Machine high-pressure series can easily lead to eccentric. Unbalanced local overloading occurs due to uneven eccentricity or uneven seating of the piston surface and the friction surface, whereas the latter results in an increase in temperature under load, deterioration of lubrication (drastic decrease in oil viscosity, dry friction and loss of metal and metal Phase bite) and piston ring, Babbitt alloy coating, bushings and other parts of the extreme wear and tear.
