中文摘要：
针对现有对柱塞泵研究的缺陷与不足，以及在使用过程中出现的非正常失效等问题，根据柱塞泵的工作原理以及现场使用情况对其进行振动失效机理研究，在对泵头、十字头、动力端、连接管线分析基础上，制定了一整套完整的振动测试方案，并将振动测试方案进行了现场的应用。结果表明：根据柱塞泵泵头、十字头、动力端、连接管线处振动强点所对应的频率为各部件的基频，可以判断出造成振动的原因。该研究结论可为降低柱塞泵的振动失效提供理论基础，对现场的安全生产。延长柱塞泵的使用寿命具有重要的指导意义。
英文摘要：
For the defects and shortcomings of the existing research on the piston pump, and the non-normal failure occurred during the use of the piston pump. Based on the working principle of the piston pump and the use of the field, the failure mechanism of the piston pump is studied. On the basis of the analysis of the pump head, the cross head, the power end and the connecting line, a complete set of complete vibration testing scheme is established, and the vibration test scheme is applied in the field. The results showed that： According to the piston head, crosshead, power end, vibration strengths connecting line at the frequency corresponding to the base frequency of each component can be determined that the cause of vibration The research conclusion can provide theoretical basis for reducing the vibration failure of the plunger pump , and it has important guiding significance for the safety production and the extension of the service life of the piston pump.
