摘要：

对SDDC型双作用液动旋冲接头主要工作过程中的能量转化及利用问题进行了分析，建立了该型双作用液动旋冲接头各工作过程的能量方程。依据能量方程，推导出了液动旋冲接头的单次冲击能量、冲击频率、水力能量利用率的计算模型，并对计算模型进行了验证。研究了泵的排量、泵压、旋冲接头的结构尺寸，以及冲锤质量等对泥浆泵工作情况及水力能量利用的影响，研究结果表明：泥浆泵的泵压、排量增大，SDDC型双作用液动旋冲接头的单次冲击能量、工作频率、水力能量利用率增大，反之，则相应减小；旋冲接头的结构尺寸和冲锤质量对水力能量的利用率影响也很大。

Abstract:

The energy equation of SDDC mode hydraulic connector was established during working, on the basis of analysis of energy transformation and utilization. According to the energy equation, a calculation model was set up, for single compact energy, compact frequency, and hydraulic energy ratio. At the same time, the influences of pump rate and pressure, dimensions and hammer mass on working process and hydraulic energy utilization were obtained. The results indicate the single compact energy, working frequency, and hydraulic energy ratio increase while the pump rate and rate increases. Also, the dimensions and hammer mass have obvious effects on the hydraulic energy ratio.

Key words: hydraulic rotating connector, rotating drilling, energy transformation, pump pressure
