提高采煤机液压、马达测试准确性的方法

采煤机液压泵和马达的测试过程中,其中任何一个参数的测量失准,均将直接影响测试结果的准确性。作者总结了测试工作中的经验,对诸多空载排量、压力、转速、转矩升温等参数的测定与控制以及敷据的同步采集等进行了分析,对如何提高测试数的准确性提出了意见,供参考。

THE METHOD OF IMPROVING THE ACCURACY OF TESTING SHEARER HYDKAULIC PUMP AND MOTOR

During the course of testing shearer hydrautic pump and motor, if any one of the parameters is measured inaccutalely, the accuracy of testing results will be affected direclly. The author sums up the experience in the tesling work and analyses the measurement and control of the parameters such as the no-load disptacement. pressure, totation speed. torque, and oil temperature etc, and the synchronized cotlertion of the data,and presents his jopintion on how to improve the accurary of the testing figures for referance.
