| 摘 要： | 目前我国采用上部卸油工艺卸轻油罐车，此工艺在夏天作业、环境温度较高，当大气压较低时(如西北高原)，极易发生气阻现象，使卸效率下降，工作时间延长，严重时甚至发生气阻断流。根据虹吸原理，考虑到罐车中油品的温度分布不均匀的实际情况，利用鹤管的两步位移来避免油温高和位能低两个因素同时出现，降低气阻现象的发生率，为轻油罐卸车提供一个简便易行的方法。

| Abstract: | Currently,upper unloading technique is adopted in China.There are many disadvantages in specific operation.According to the theory of siphonage,think over the fact that oil temperature disperses unevenly in tank train,make use of the displacement of crane tube to avoid the simultaneous emergence of high oil temperature and low pressure and reduce the appearance of gas blockage and provide a convenient way for unloading light oil tank train. |
