１．修复工艺分解清洗后，对所有零件都进行严格检查，发现造成柱塞泵内漏的主要原因是：柱塞与柱塞孔磨损后配合间隙过大，缸体球面与配流盘的配合面都磨损不均匀。因此，解决内漏的关键是必须使柱塞与柱塞孔的配合间隙恢复原标准，缸体球面与配流盘的配合面可用研磨法使其达? 1. After the repair process was decomposed and cleaned, all the parts were strictly inspected and found that the main reason causing the internal leakage of the plunger pump was that the clearance between the plunger and the plunger bore was too large, and the mating surfaces between the cylinder spherical surface and the valve plate were worn Inhomogeneous. Therefore, the key to solve the internal leakage is to make the plunger and the plunger hole with the original return to the standard clearance, the cylinder surface with the valve plate can be matched with the grinding method up to?
