Abstract

An electro-magnetic driven miniature piston pump with novel mechanism has been developed for testing the feasibility in the present study. The novel mechanism is a hollowed piston in axial direction with a membrane served as a check valve. The operation of this novel pump is driven by electro-magnetic force to produce reciprocating motion with periodical switch of magnetic poles. The detailed operating principle is described for the magnetic driven reciprocating pump. The working fluid is water in this investigation. Our results include the performance and characteristics of the novel miniature pump. Testing results show that the maximum head is linearly proportional to the applied electric current. In addition, the relation between the head and flow rate is also close to linear, except for extreme conditions. The hydraulic efficiency and the volume efficiency were calculated to be close as 0.96 and 0.95, respectively.
