在云南漫湾水电站工地，我局一台挖装石方的德国利勃海尔R982型液压挖掘机突然回转失灵，不能动作，经检查发现斜盘式轴向柱塞泵有多个滑靴拉断，使柱塞与滑靴分离，不能工作。我们尝试采用铜合金加工滑靴，以应急修复。但经修复的泵运转一小时就在原断面最小处拉断（如图1）。 Manxia Hydropower Station in Yunnan, I Bureau of a digging stone Liebherr Germany R982 hydraulic excavator sudden failure failure, can not move, the inspection found that the swash plate axial piston pump pulled off a number of slip , So that the plunger and the slipper separation, can not work. We try to use copper alloy processing slipper, emergency repair. However, the repaired pump runs for an hour and breaks off at the minimum of the original section (Figure 1).
