我单位有两台大型联合收割机,其水箱在前一年的秋收作业中没有发生渗漏现象,但在下一年夏检试车时却发现散热器管漏水严重。检查与分析原因:一是驾驶员在给机车加水时,没有遵守应加沉淀后的软化水的要求,而是经常添加沟塘水,导致散热器管的某一头堵死而将管憋鼓、憋裂;二是冬季作业时冷却水没放净,致使散热器管冻裂。 My unit has two large combine harvester, the water tank in the previous year’s autumn harvest operations did not happen leakage, but in the summer of next year when the test car found radiator water leaks serious. Check and analyze the reasons: First, the driver to add water to the locomotive, did not comply with the requirements should be added after the demineralized water, but often add ditches water, leading to one end of the radiator tube is blocked and the tube repercussion drum, Cracking; Second, the cooling operation did not put the net work in winter, causing the radiator tube cracking.
