摘要
高温热油泵的密封一直是炼化设备管理上的难点,本文利用非接触式上游泵送液膜密封技术,以波纹管作用机械密封的弹性元件,成功解决了高温热油泵的机械密封问题,并取得了良好的经济效益。
Based on the conditiongs characteristics of mechanical seal of the hot oil pump,with the principle of upstream pumping mechanical seal,the problem of the seal of the hot oil pump in Petroleum Chemical and refinery is solved,with the bellows as the spring assembly.
