“齒輪泵竄油”，即液壓油突破骨架油封溢出。維修挖掘機起動復合繼電器的中點信號端有電源電壓（檢查中點信號端信號的輸入是否與電源有短路現象或起動機中點輸出不正常）。挖掘機修理則閃光繼電器已損壞；當手柄開關撥到左轉或右轉時，若方向機下面的左右轉向指示燈閃爍，而挖掘機左右轉向燈不閃爍，請檢查閃光繼電器到挖掘機左右轉向燈的線束連接及負載燈是否被燒壞。挖掘機維修左右轉向(xiang)指示(shi)燈工作不(bu)(bu)正常(chang) 當(dang)手柄(bing)開關撥到左轉或(huo)右轉時，挖掘機左右轉向(xiang)燈不(bu)(bu)閃爍。請檢查左、右轉向(xiang)燈與(yu)閃光(guang)繼電器(qi)負載(zai)端之間的(de)線束。這(zhe)種(zhong)現象在主機廠普(pu)遍存(cun)在，反映強烈。齒(chi)輪(lun)(lun)泵(beng)漏油(you)嚴重影響裝載(zai)機的(de)正常(chang)運行、齒(chi)輪(lun)(lun)泵(beng)的(de)可靠性和環境污(wu)染。針對(dui)這(zhe)一問(wen)題，分(fen)析了齒(chi)輪(lun)(lun)泵(beng)油(you)封漏油(you)的(de)原因(yin)及控制方法。
