针对目前钻井柴油机节能监测方法存在测试项目多、数据可靠性差、计算过程复杂、累计误差大等问题,通过对现有的扭矩和转速测量方法和数据传输技术等进行系统分析和研究,研制了一套适用于钻井柴油机的输出扭矩和转速测量系统。实验表明,该系统的测量精度能够满足SY/T 5030《石油天然气工业用柴油机》中对柴油机输出扭矩和转速的测量误差范围的要求。通过现场应用,证明该系统测试效果良好,进一步提高了钻井柴油机节能监测与评价工作的科学性和准确性。

To solve the problem of various test items,poor data reliability,complex calculation process and large accumulative error in the energy saving monitoring method of drilling diesel engine,by analyzing and studying the existing torque and speed measurement method and data transmission technology,this paper developed a set of output torque and rotational speed measurement system for drilling diesel engine.The test shows that,the measuring accuracy of the system can satisfy the measurement error range of the diesel engine output torque and speed in the SY/T 5030＂the diesel engine for the petroleum and natural gas industry＂.The effect of the system is proved through field test,and that can improve the scientific and accuracy of energy saving monitoring and evaluation of drilling diesel engine.
