我厂 L3.3—17/320型压缩机,其联轴器上橡皮胶圈自随机投入运行以来,使用情况良好,胶圈寿命正常,对压缩机正常运行无任何影响。但是在1988年,我厂1号高压机出现异常情况,高压侧联轴器胶圈经常烧毁,甚至是新换的一组胶圈,连运转8h都不能保证。为此我们曾对该机作了彻底检修,严格控制缸套间隙、余隙等各项技术尺寸,更换联轴器, I plant L3.3-17 / 320 compressor, the rubber ring on the coupling from the random operation, the use of good condition, the normal life of the apron, the normal operation of the compressor without any impact. However, in 1988, I plant an abnormal situation on the 1st high-pressure machine, high pressure side of the rubber ring seals are often burned, or even a new set of rubber ring, even the operation 8h can not be guaranteed. To this end we have made a thorough overhaul of the aircraft, strict control of cylinder liner clearance, clearance and other technical dimensions, replacement couplings,
