ZBJ13粗浆泵轴护套原机设计形状如图1,我厂对轴护套结构作了如图2所示的改进。将原泵轴上键槽、键适当加长,安装时让轴护套缺口卡在轴键上,保证与轴同转。通过改进,使轴护套结构得到简化,制造容易,节省原材料,维修换件省时省力,维修工人都说好。 ZBJ13 crude slurry pump shaft sheath original design shape shown in Figure 1, I plant on the shaft sheath structure as shown in Figure 2 shows the improvement. The original pump shaft keyway, the key lengthened, the installation of the shaft sheathing notch card stuck on the shaft key, with the shaft to ensure the same turn. Through the improvement, the structure of the shaft sheath is simplified, the manufacture is easy, the raw materials are saved, the time and labor saving for the replacement parts are saved, and the maintenance workers all say that they are good.
