在用泥漿進行鑽探時,因为泥漿或水內含有不同程度的砂粒雜質,沉澱在缸套下部,因而泥漿泵的缸套與皮碗磨損很快。必須經常更换缸套或皮碗,才能保持足够的水壓或水量。根據對缸套內徑被磨損部位的分析,AB部份磨損最为嚴重(如圖),因此,我們採用了切削磨損缸套內徑,加大皮碗的辦法來延長缸套的使用時間。其具體作法是:當缸套內徑磨損到一定程度時,將缸套內徑削去一層,削去多少,应根 When drilling with mud, the mud pump or cylinder liner will wear out quickly because the mud or water contains different levels of grit and deposits on the lower part of the liner. Cylinder liners or cups must be replaced frequently to maintain sufficient water pressure or volume. According to the inner diameter of the cylinder was worn parts of the analysis, AB part of the most serious wear (Figure), therefore, we use the cutting wear cylinder liner diameter, increase the cup way to extend the use of cylinder liner. The specific practice is: When the cylinder liner diameter wear to a certain extent, the cylinder liner diameter cut a layer, cut how much, should root
