过去较长时期内,一直简单地认为拖垃机的使用年限越长越合算。当然在五十年代,国家向农场投放农机具初期,国家农机产品不多,提倡延期使用是必要的。当农场的农机化事业发展到今天,这种无限期使用的方法,是否经济合理,需要作一点经济分析了。本文仅依调查资料,谈几点粗浅看法。一、使用年限与修理间距的关系机械的磨耗总是随着使用时间的增长而增大。人们只能采取措施延长自然磨耗期,
For a long time in the past, it has always been simpler to think that the longer the service life of the tractor is, the more cost-effective it is. Of course, in the early 1950s, when countries started to put farm machinery on their farms, there were not many agricultural products in the country and it was necessary to promote the use of the farm machinery. When the farm’s agricultural mechanization develops today, this method of indefinite use is economically reasonable and requires some economic analysis. This article only based on the survey data, talk about a few superficial views. First, the relationship between service life and repair distance Mechanical wear is always increasing with the use of time. People can only take measures to extend the period of natural wear and tear,
