基于振动测试的钻井泵故障诊断测试点优选

Optimization of Fault Diagnosis Test Point for Drilling Pump Based on Vibration Test

钻井泵是油田常用的油气开采装备。在振动测试过程中,由于钻井泵核心部件多且间距较小,无法确定合适的测试点以获取有效的数据。论文通过小波包分解低频段能量比值的实验方式,选取其中最小值,获取适合F1300型号钻井泵的最优测试位置。

Drilling pump is a common oil and gas mining equipment in oil field. During the vibration test,it is impossible to determine the appropriate test points to obtain the valid data because the core components of the drilling pump are many and the distance is small. In this paper,an experimental method of decomposing the low frequency energy ratio by wavelet packet is used to select the minimum value to ob-tain the optimum test position for the F1300 model drilling pump.
