内燃机水泵能效评价方法探讨

内燃机水泵能效评价指标包括泵效率、总效率和燃油消耗率。泵效率来源于泵类产品的能效评价，其方法来源于GB／T24673—2009小型汽油高速离心泵能效评价体系，不足在于测量输入功率时对样机的损坏，导致装配测量误差增加。总效率来源于潜水电泵能效评价，由于输入功率、油料发热值计算的不确定性，致使计算值与真实值误差。燃油消耗率来源于内燃机能效评价，即JB/T6665轻型柴油机泵能效评价体系，其燃油消耗率计算方法欠妥，为内燃机水泵能效评价留下了严重漏洞。本文通过对集中评价方法计算分析，结合试验数据，从参数敏感程度、参数习惯性、参数曲线差异、标准依据、测试方法科学性、测试参数准确性、环境影响等方面做了较深入的分析探讨，发现采用燃油消耗率法评价内燃机水泵能效最优。

Explore the internal combustion engine pump energy efficiency evaluation method

Energy efficiency of Engine pump consist pump efficiency, total efficiency, and specific fuel consumption. Pump efficiency comes from the pump conduction, and the method comes from energy efficiency evaluation of GB/T 24673-2009 small gasoline -speed centrifugal pumps. The damage to prototype because of input power measuring could lead to error increases of assembly measurement. Total efficiency originates from submersible pump, because of the uncertainty of the calculation of input power and fuel heating value, lead to generation of error between calculation and truly value. Specific fuel consumption originates from energy efficiency evaluation of JB/T 6665 small diesel pumps. The energy efficiency evaluationof engine pump exist shortcomingdue to the disadvantage of the method of calculation of specific fuel consumption. By the analysis of evaluation Method, combining test, to research the parameter sensitivity, parameters habitual, parametric curve differences, standard basis, scientific testing methods, accuracy of the test parameters, and environmental Impact, discovery that using specific fuel consumption is the best way to evaluate engine pump.
