我厂 L5.5-40/8型空气压缩机,已运行14年,机身轴承严重磨损,轴承跑外套,主轴径向跳动,电机转子与定子磨擦,噪声强烈,于1990年3月被迫停机。经解体检测,轴承孔已由设计要求的Φ300±8:8_(36)~(16)增大至Φ300~(+0.16)。采用等离子喷涂方法对机身轴承扎进行修复后,使该机迅速恢复了正常运行,经一年多时间的实践 I plant L5.5-40 / 8 air compressor, has been running for 14 years, the body bearing wear and tear, the bearing running jacket, spindle runout, the rotor and the stator friction, noise, was forced in March 1990 Shut down. After the disintegration test, the bearing hole has been increased from Φ300 ± 8: 8_ (36) ~ (16) to Φ300 ~ (+0.16). Using plasma spray method to repair the fuselage bearing tie, so that the machine quickly returned to normal operation, after more than a year of practice
