钻井泵阀位移测试系统及位移测试

在研究钻井泵阀的运动规律时，为了避免因纯理论的推导而得出不切实际的结论，在泵阀试验台上采用自行设计的测试系统，对泵阀位移及运动规律进行了测试。通过测试和分析，得出了泵阀关闭速度与泵压基本无关、泵阀关闭时的冲击能较小的结论。实践表明，泵阀位移及运动规律的测试精度能满足理论分析的要求。

Testing system for displacement of drill pump valve

In the research of the motion pattern of the drill pump valve, in order to obtain practical result, the displacement and motion pattern of the pump valve are tested on the test bed by the testing system designed by the authors themselves.The test result shows that the closing speed of the valve is not related to the pumping pressure, and the minor impacting energy is produced in the course of valve closing. Practice proves the testing accuracy of the displacement and motion Pattem of the drill pump valve meeting the demand of theoretical analysis.
