摘　　要：针对丁二烯螺杆压缩机原用轴封存在密封介质泄漏严重、使用寿命短等问题 ,开发出油膜润滑上游泵送机械密封并成功应用在该机上 。On the basis of analysis of the failure reasons of traditional contacting mechanical face seal used on butadiene screw compressor, the upstream pumping mechanical seal for screw compressor was developed and used successfully. It is available to resolve the leakage problem of the similar compressor set.
