故障現象: 整機號:YC10-C5037                                     

                            工作時間:2900 小時                                    

                            工作狀況:    礦山采石                                  

                           故障現象:該機每天都會出現冷卻水不足報警,                                     

                                                       

                                                       

                                                       

                                                       

                                                       

原因分析:             

                     1.出現冷卻水報警后檢查副水箱發現副水箱冷卻水特別多,而主水箱里確實缺水了, 

                     先懷疑是水箱蓋或主副水箱之間的連接管道有問題,全部更換后故障依然存在.                                       

                                                       

             

                    2.打開水箱蓋后將發動機處于高油門發現水箱里有大量氣泡冒出,所以初步判斷為 

             缸墊被沖破.                                        

                                                       

                    3.做斷缸實驗發現斷5缸后觀察水箱氣泡明顯減少,判斷為5缸處缸墊被沖破                                         

                                                       

                    4.拆開缸蓋后發現缸墊在5缸附近的螺絲孔損壞                                       

                                                       

                                                       

                                                       

處置方法:                                                       

                                                       

              更換缸墊
