目前，地质勘探使用的油压钻机其液压系统均配置不同型号的齿轮油泵。由于使用上的一些原因，油泵损坏较快。在报废的油泵中，我们发现大多数油泵的齿轮、轴承等零件基本完好，可以再使用，仅因铝合金泵体进油腔室磨损而整个油泵报废，这的确是个浪费。为了作到物尽其用，我们便试图修复泵体。修复泵体的困难是：泵体的材料是铝合金的，我们不能堆焊修复；又因泵体腔室几何形状特殊，不可能静配合镶套，经多次摸索，采用无机粘接镶套修复获得成功。 At present, the hydraulic rigs used for geological exploration are equipped with different types of gear pumps. Due to the use of some reasons, the pump damage faster. In the scrapped pump, we found that most of the pump gear, bearings and other parts basically intact, can be reused, just because the aluminum alloy pump into the oil chamber wear and tear of the entire pump, which is indeed a waste. In order to make the best use, we try to repair the pump body. The difficulty of repairing the pump body is: the pump body material is aluminum alloy, we can not surfacing repair; and because of the pump chamber geometry special, can not be static with the insert sleeve, after repeated exploration, the use of inorganic adhesive insert sleeve repair Success.
