The Research On Properties Of A New Linear Electromagnetic Oscillation Pump

The miniaturization of pump has been developed not only in industry filed, but also in our daily life. Reciprocating pump has been used widely nowadays, it gave rise to products of different types, different structure and different uses. However, the traditional reciprocating pump use the structure of crankshaft connecting rod or cam mechanism, which convert rotary motion to reciprocating motion. The disadvantages just like low efficiency, large size, easy to wear and lower life were restricted the development of traditional reciprocating pump. Now the popular miniaturized linear reciprocating pump are piston pump and ram pump which drove by linear motor.This paper mainly focuses on the research on a kind of small-sized piston pump drove by electromagnetic, which is often used in water cooler, automobile radiator, cleaning machine etc. The pump has the advantages of small flow rate but high frequency and stability output flow. For linear motion characteristics of electromagnetic oscillations of the pump, and the impact of structural parameters on the piston simulation calculations to verify the theoretical design requirements, to discuss the main design parameters of the pump characteristics.The structure design of miniaturized pump is critical. The research content discussed in this paper is a kind of small-sized piston pump base on the47DSB pump drove by electromagnetic, it has many characteristics, such as small, smooth run, low noise etc. the characteristics of spring forced oscillation system on linear oscillatory pump were analyzed based on the structure of pump, parameters of electromagnetic actuator and the movement rule of pistons and valves. Simulation calculation for electromagnetic field of actuator and AMESim simulation modeling of linear oscillatory pump and cam-drive mechanism reciprocating pump were discussed. Described the effect of the electromagnetic force frequency on the pump function, compared the characteristics of linear oscillatory pump with cam-drive mechanism reciprocating pump. Thus it provides a theoretical basis for design and optimization of this kind of pump.
