安装液下泵需要注意哪些问题

 轴承组件装置液下渣浆泵的时分需求预热轴承组件，温度不能够超越120°c，下部轴承采用双列圆锥滚子轴承，其内圈、外圈、定位套等是成套组件，不允许与同类轴承的相应零件交流，在安装轴承下端盖时需留意下端盖凹槽内的唇口密封圈的唇口应向外。

　　甩油环等有必要契合装置图中的方位，安装迷宫环时需留意迷宫环的启齿在直径方向上应错开。虽然轴承自身已确保了轴向空隙，故液下泵的轴承组件在组装中不需调整空隙，但组装好后，倡议依照下表列出的值查看安装的端面空隙。

　　轴承组件 端面空隙支架、安装板和泵体的安装将轴承组件与支架用螺栓联接，在支架圆周外装上对开的安装板，用双头螺柱固定在只加上，然后装入后护板、叶轮、泵体。装置时须留意轴承体、支架、安装板与泵体之间的相对方位，须契合下图，以确保出水管和油咀的相对方位。

　　液下渣浆泵及立式渣浆泵装置留意事项支架与泵体的联接螺栓有必要上紧，查看叶轮滚动能否平稳，若有摩擦，则能够在轴承体和支架联接螺栓处加垫调整，最终安装上、下滤网和吐出管，吐出管上方用螺钉固定在安装板上


When installing the submerged slurry pump, the bearing assembly shall be preheated, and the temperature shall not exceed 120 ° C. the lower bearing adopts double row tapered roller bearing, and its inner ring, outer ring and positioning sleeve are complete components, which are not allowed to be exchanged with the corresponding parts of similar bearings. When installing the lower end cover of the bearing, pay attention to the lip in the groove of the lower end cover, and the lip of the sealing ring shall be outward.
It is necessary for the oil slinger to comply with the orientation in the installation drawing. When installing the labyrinth ring, it should be noted that the opening of the labyrinth ring should be staggered in the diameter direction. Although the bearing itself has ensured the axial clearance, so the clearance of the bearing assembly of the submerged pump does not need to be adjusted during assembly, it is recommended to check the end face clearance of the device according to the values listed in the table below after assembly.
The bearing assembly is connected with the support by bolts. The split device plate is installed outside the circumference of the support and fixed on the support with double studs, and then installed into the rear guard plate, impeller and pump body. During installation, pay attention to the relative orientation between bearing body, support, device plate and pump body, which must comply with the following figure to ensure the relative orientation of outlet pipe and oil nozzle.
Precautions for the installation of submerged slurry pump and vertical slurry pump: it is necessary to tighten the connecting bolts between the support and the pump body to check whether the impeller rolls smoothly. If there is friction, pad the connecting bolts between the bearing body and the support for adjustment. Finally, the upper and lower filter screens and discharge pipes of the device are fixed on the device plate with screws above the discharge pipe
