| 摘 要： | 分析了离心泵接卸铁路轻油槽车出现管路气阻和泵抽空的原因，介绍了通过采用真空辅助轻油卸车工艺控制集气罐内真空度、调节卸油管路最高点和离心泵入口两处绝对压力、消除管路气阻和泵抽空的过程。对真空辅助轻油卸车工艺与压卸车工艺进行了比较，结果表明，前者安全性高、能耗低、操作方便，具有推广应用价值。

| Abstract: | The paper analyzes the causes of air-lock and pump off of centrifugal pump produced during the light ends unloading operation of rail tanker. To solve this problem.the measures to eliminate the air-lock and prevent centrifugal pump from evacuating are presented, that is, controlling the vacuity of gas gathering tank with the technology of vacuum-serving unloading .and adjusting the two absolute pressures at the climax of unloading arm and the inlet of centrifugal pump. An economic comparison is made between the vacuum-serving unloading technology and positive pressure unloading. The results show that the vacuum-serving unloading technology has obvious advantages in high safety, low power consumption and convenient operation. |
