《工程机械》1978年第2期上发表的西南交通大学易新乾同志的文章“大修后的机器可以经久耐用”,提出了一个很值得研究的问题,即大修后的机器能否达到新机器的使用寿命?目前不少施工单位拥有几百台、甚至上千台机械,如果能通过提高机械修理后的使用寿命,就相当于新增加几十台甚至上百台新机械;如果全国的机械修理部门都能这样,那将对我国的社会主义建设和四个现代化作出多大的贡献啊!下面想就与此有关的几个问题进行讨论。需要说明的一点是:这里所谈机械的使用寿命是指大修后的机械从出厂到下次大修的使用时间,而并非指机械从出厂到报废的整个使用期。
Comrade Yi Xingan of the Southwest Jiaotong University published in the second issue of the “Construction Machinery” in 1978 published an article “The overhauled machine can be durable.” It puts forward a question worth studying, namely whether the overhauled machine can reach the new machine. The service life? Currently many construction units have hundreds or even thousands of machines. If we can increase the service life of machinery after repair, it will be equivalent to adding dozens of new machines or even hundreds of new machines; if the country’s mechanical repairs All departments can do that, and that will make much contribution to the socialist construction of our country and the four modernizations. We want to discuss several issues related to this. It should be noted that the service life of the machinery discussed here refers to the use time of the overhauled machinery from the factory to the next overhaul. It does not refer to the entire service life of the machinery from the factory to the end of life.
