转桨式水轮机的受油器在运行过程中多次发现青铜衬套与活塞杆工作表面磨损严重,引起漏油,导致必须研磨处理活塞杆,更换衬套,此时并发现如下情况: 尽管活塞杆和主轴之间是经过仔细地校中心,也仔细地检查过衬套的同心度及衬套与活塞杆之间的间隙,可是仍然产生磨损; 检修后运行时间越长,衬套和活塞杆的磨损程度就越小,并且发现受油器内油低速
During the operation of the paddle turbine, it was found many times that the working surfaces of the bronze bushing and the piston rod were worn seriously, causing oil leakage, resulting in the need to grind the piston rod and replace the bushing. At this time, the following situation was found: although the piston After carefully centering between rod and spindle, the concentricity of the bushing and the clearance between the bushing and the piston rod were also carefully inspected, but wear still occurred. The longer running time after the inspection, the bushing and piston rod Less wear and tear, and found that the oil inside the oil low speed
