Abstract:

Based on the analyses of rotating-guide-bar and gear mechanisms assembled driving system of differential velocity vane pump,a 3D simulation model and its structure design were made. Its technical parameters of the driving system was determined and the prototype was developed. A mechanics model of the rotating-guide-bar and gear mechanisms assembled driving systems was established and the variation law of its work resistance torque was obtained. Its experimental research platform of the prototype on differential velocity vane pump was set up to test the situation of draining and aspirating fluid. The results show that the differential velocity vane pump with rotating-guide-bar and gear mechanisms assembled driving systems can achieve the function of draining and aspirating fluid and the driving design and its structure design are proven to be correct.

Key words: differential velocity vane pump, driving system, rotating-guide-bar and gear mechanisms, mechanics performance, draining and trapped fluid
