The Structure Optimization of Double Feeder System Core Components

The work investigates the structure parameters of adjustable subatmospheric pumping scraps device and oil feeder, which have extremely significant impacts on double feeder system in the deep-hole drilling process. Equations for subatmospheric zone pressure are derived herein using the siphon principle, and experiments are performed the trends of pressure on the single factor condition, which provide reasonable structure parameters for adjustable subatmospheric pumping scraps device. Oil feeder is studied based on the Euler column theory, and it can be optimized that is intermediate support, pilot bushing as well as sealing. The universal finite element software is used to design the structure of adjustable subatmospheric pumping scraps device and oil feeder, also reasonable structure design scheme of double feeder system core components is given.
