蒽油采出泵密封的研究与改进

Study and improvement on the sealing of anthracene oil recovery pump

煤焦油加工通常是在高温下运行,采出的蒽油温度高达220℃,对泵的密封要求很高。对蒽油泵的密封方法进行了研究,并实施了技术改造,改造后泵运转正常,效果良好。

Coal tar is normally processed under high temperature. The temperature of recovered anthracene oil is up to 220℃,so it is very important to tightly seal the pump. After studying the sealing method and implementing renovation to the anthracene oil pump,the pump shows good performance.
