The article analysed the system structure,the operating characteristics and the static relationship between extruded striking force and oil pressure of NPS clutch attributable to high-octane screw press.It indicated a unique approach to improvement of dynamic response in process of press discharge. It intended to develop an original high-octane screw press to solve the problems such as control of final striking force and overmuch friction consumed during the process discharging. The clutch was designed in light of self-locked theory and can effectively control striking force through cooperation of transducer, hydraulic valve and release valve.The article introduced the working principles and the structural characteristics of high-octane screw press with rapid discharge. On the basis of simulation theories and experimental results of sample tests, the article explains that the new-type machine can help to improve response speed and performance of screw press, as well as to provide useful references to optimum design of the clutch system in high-octane screw press.
