摘　　要：分析了手动喷雾器与电动喷雾器各自的优缺点,介绍了国外电动喷雾器用泵的类型及其特点.针对电动喷雾器用泵的不足之处,提出了一种拥有自主知识产权的创新型双作用滚柱转子泵.阐述了双作用滚柱转子泵的工作原理是利用滚柱与定子内壁的滚动摩擦来代替传统的滑动摩擦,从而减少了摩擦损耗;同时其双进双出的双作用对称式结构,改善了转子与轴的径向受力不平衡问题,延长了产品使用寿命.对定子型线中过渡曲线采用八次曲线进行设计,提高了产品可靠性.经检测及与其他同类产品相比较,得出该种电动喷雾器用双作用滚柱转子泵具有高效率、低噪声的特点.The advantages and disadvantages of manual and electric sprays, and the characteristic of foreign-made electric spray pump were discussed. A new type of double action roller rotary pump was developed which belongs to positive displacement rotary pump. The new pump uses rolling friction to replace sliding friction and thus has lower frictional loss. Meantime, it uses symmetric structure with double inlet and outlet, which improves the radial force balance. All the above increase the service life. Eighthpower curve was used for drawing the transitional curve of the stator. Compared with other products, this new pump shows high efficiency and low noise.
