Study on energy ratio of SDDC hydraulic connector

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.
