| The electrical motor of traditional reciprocating pump transforms electric energy into rectilinear mechanical energy by crank link gear. Its efficiency is low. The delivery rate and pressure pulsate greatly. The working time of replacement parts is low. The linear motor transforms electric energy into rectilinear mechanical energy directly. The foregoing problem will be resolved when using linear motor as driving force of the reciprocating pump.In this paper, a test system was installed to check the design target, test the practical working performance and motion property of linear motor reciprocating pump. Based on the theory analysis and structural design, a motion plan has been determined for the control strategy of linear motor and the goal of constant output flow rate.The design of pipe line was finished in connection with the objective of testing the flow rare, pressure and the characteristics of plunger motion. The selection of pipeline, measuring device of flow rate and pressure, data collection system was finished in this paper. The installation and debug of the experiment system was finished. The control parameter of linear motor was adjusted and optimized. An effective control model has been chosen to enhance the controlling resolution. The disturbing signal occurred in the data collection has been optimized. In this paper, the experiments have been carried on in different frequency of stroke and different pressure. The data of plunger motion, pressure and flow rate was analyzed and compared with each other. We investigated the reason for the fluctuation of output flow rate and pressure. Some effective improvement measures have been put forwarded in this paper.
