由于工程机械在使用过程中，受腐蚀及交变荷载的作用，铸件（如工程机械的柴油机油底壳、水箱和变速器壳体等）缺陷处易产生应力集中，使其缺陷逐渐扩大，从而导致渗漏。通过实践，我总结出４种处理铸件渗漏的简易方法。１．填补法对铸件进行水压试验，找出渗漏部位，然后用錾 Due to the corrosive and alternating loads, the defects of the casting (such as diesel engine oil pan, water tank and transmission casing of construction machinery) are easily concentrated due to the corrosion and alternating load during the use of the construction machinery, and the defect gradually expands, resulting in leakage. Through practice, I conclude four easy ways to deal with casting leakage. 1. Fill method hydrostatic test castings to identify leakage sites, and then use 錾
