去年在农机普查中发现,部分拖拉机使用寿命过短,除个别因为质量外,机手的不正确使用、维护、保养也是一个重要的原因,概括起来主要有以下九方面的因素: 一、拖拉机长期超负荷作业超载后零件负荷增加,润滑条件变差,磨损加剧。轮胎的磨损也加快,有的甚至造成机毁人亡。二、擅自增大转速有相当一部分从事输运作业的机手,为了提高车速而加大皮带轮直径或任意调整调速器限速螺钉,从而破坏了拖拉机的动平衡,加剧了
Last year in the general survey of agricultural machinery found that some tractors life is too short, except for individual because of the quality, the incorrect use of the hand, maintenance, maintenance is an important reason, summed up mainly in the following nine aspects: First, the tractor long-term After overload overload overload parts load, lubrication conditions worsened, increased wear and tear. Tire wear also accelerated, and some even caused plane crash. Second, unauthorized increase speed There is a considerable part of the transport operations of the hands, in order to increase the speed and increase the pulley diameter or adjust the governor speed limit screw, thus undermining the tractor balancing, exacerbated
