200D40×7多级水泵的轴向力平衡机构(图1)设计在泵末级时轮1,利用固定在泵体5上的平衡套3直接抵住装配在轴上的平衡盘4,阻止轴向移动。平衡套与平衡盘是一对磨擦副。
200D40 × 7 multi-stage pump axial force balance mechanism (Figure 1) designed at the end of the pump hour wheel 1, the use of the fixed sleeve 3 on the pump body 5 directly against the balancing plate mounted on the shaft 4 to prevent the shaft To move. Balance sets and balance plate is a pair of friction pair.
