The Key Technology Study Of Double-Action Roller Pump

This topic originates from Zhejiang Shixia sprayer Ltd for the Zhejiang Province Economic and Trade Committee that bear answering the technical trade barrier technology research project《Development Low Energy consumption Double-action Roller Rotary pump For The Intelligent electric sprayer》. This theme promotes the necessary request in view of the manual sprayer and the imitation pump product existence flaw, studied and proposed a new type of the double-action roller rotary pump for the electric sprayer; The job studying includes the mainexperiment:(1) Forms a complete set according to the electrically operated sprayer with the pump characteristic request, first a type of double-action roller pump for electric sprayer-used was developed in this paper, and then its structural feature and operational principle were introduced.(2) Performance computation method research. Refer reciprocating pump flux calculation formula, inferred the double-action of electrical sprayer-used roller pump’s flow formula for the average and the transient flow formula.(3) Line analysis and determination. Based on the roller in the stator inner surface movement condition, set up its movement mathematical simulation; combination of mechanical analysis of studies from the eight curves posed by the stator-profile line. This line was good has solved roller’s along stator inner surface roll time impact difficult problem, so that pump is running more stable, lower noise.(4) Roller movement and stress analysis. The roller is this pump essential fluid strength part, it makes the rolling motion with the stator inner surface, the friction coefficient of small, less reactive power consumption, wear and tear, long life, this article according to the roller movement condition, the detailed analysis roller work was stress situation.(5) Test. The development prototype after the Zhejiang Province mechanical and electrical products quality detection, examines the product performance to achieve the design requirements; The product and the domestic similar products compare, the new development’s double-action roller electrically operated atomizing pump has highly effective, low noise and so on.
