Working Principle and Verification of Electromagnetic Force Interaction Plunger Pump

The structure principle of the electromagnetic force interaction plunger pump is put forward. With the linear motor as the dynamic element, the armature plunger of the two cylinders is linked by the rack and pinion mechanism, and then the electric energy is converted into the fluid pressure energy. In the field of agricultural machinery, automotive or construction machinery have a broad application prospects. The structure and working process of the electromagnetic piston pump are described, and the stress and system efficiency of the gear rack and the mechanism are analyzed. Developed the principle to verify the prototype, through the test, with the armature plunger stroke increased electromagnetic force gradually increased from 130N to 450N, work more smoothly with water for the working fluid. The pump works is feasible, and the next step should be based on the optimal design and development of performance prototype to make a complete system of product feasibility assessment.
