3иФ—P200/40泥浆泵的瓦拉座易经常冲坏,有时甚至将安装瓦拉座处(如图1B)的壳体冲坏。此如不及时修复任其下去,将会使壳体报废。为此,现将我们的修理方法作一介绍,供各队参考。瓦拉座壳体的镗孔是在2A125鑽床上进行。然后再用镶套的方法恢复。首先将泥浆泵壳体安装在鑽床工作台上,并大致找平。然后依照图2所示的方法最后找平和找出瓦拉座竞体孔的中心。 The wall brackets of the 3иФ-P200/40 mud pumps are often washed out, and sometimes even the shells at the mounting brackets (Fig. 1B) are damaged. If this is not repaired and allowed to continue, the shell will be scrapped. For this purpose, we will now introduce our repair method for reference by each team. The counterbore of the Wallet housing is made on a 2A125 drill press. Then use the insert method to recover. The mud pump housing is first installed on the drill table and roughly leveled. Then, according to the method shown in Fig. 2, finally level and find out the center of the hole in the Walla race.
