摘　　要：通过对市场水泵漏液故障的分析,发现存在部分的水泵漏液误判。针对这一误判现象,我们通过对水泵机械密封工作原理的阐述以及故障现象的分析,并通过漏液的痕迹来推断水泵漏液的根本原因并给出推断方法来定性分析水泵漏水的具体原因。本文对售后市场判断此类故障提供了较好的指导方向。By analyzing the water pump leakage on the engine from after-sale, we didn’t find any water pump leakage. This paper tells that what the mechanical seal is and what the principle is. Based on this phenomenon, and it analyzes generally what the root cause is.The technician can judge what root cause is based on the leakage trace. It provides better guidance for fixing the trouble of the water pump leakage on the after-sale.
