Design of Pneumatic Rotor Pump Mechanism and Dynamics Analysis

摘要

To meet the special needs of the bolting and shotcreting work environment of coal mine, a new pneumatic spring-piston mechanism was designed. The derivation process of the pressure loss equation was described based on S.Morinaga formula. The concrete pumping machanism kinetic model was constructed and analysed using Lagrange's Equation. The work of this paper lays a theoretical foundation for optimization design of wet spraying machine system.
