摘要(Abstract):
输油泵的主要评价指标是泵效率。测量参数的质量对输油泵效率测算结果准确程度影响很大。本文根据不确定度分析原理,建立了输油泵效率测算的不确定分析模型,并给出了计算方法。在此基础上利用实际测算数据,计算了3台输油泵的不确定度。本方法同样适合于其它机泵效率测算分析。
The efficiency is a primary evaluating indicator for oil transportation pump. The quality of measured parameters influences the system efficiency greatly.The analysis compendium of uncertainty was introduced. Then, three oil transportation pumps is employed as an example to illustrate the proposed method.
