Dynamical Simulation Analysis on High Pressure Water Injection Pump

The development of petroleum mechanical equipment in China was reviewed and the importance to apply modern design methodology to petroleum equipment in China was suggested. Dynamical simulation and its related technique were also given. 3H-8/450 pump was studied. The simulation model was set up. Dynamics and kinematics simulation analysis were processed, and drive torque for this system was also calculated, Results in theory were used to check the model and motion analysis results, After reviewing the motion analysis results, some advices for the improvement of the pump were given, Simulation analysis is processed on the pump which is improved, and results show that reaction forces are decreased.
