1.结构图1表示的是把一般的感应电动机直接连结起来的最普通的屏蔽泵(简称R型屏蔽泵),图2、图3表示的是把扁平电动机(轴向气隙型感应电动机)直接连结起来的屏蔽泵(简称A型屏蔽泵,即端面屏蔽泵)。这两种都是标准的基本型式。首先就图1结构作大致的介绍:叶轮2直接安装在转子24的轴26上,叶轮 1. Structure Figure 1 shows the most common shielded pump (R type shielded pump) that directly connects a common induction motor. Figure 2 shows the flat motor (axial air gap induction motor) Shield directly connected pump (A type shield pump, the shield shield). Both are standard basic types. First of all, the structure of FIG. 1 is roughly introduced: the impeller 2 is directly mounted on the shaft 26 of the rotor 24, the impeller
