在正常情况下,对新买的机具按规定磨合、调整之后,将会达到良好的技术状态,使用较长一段时间后,其动力性、经济性才开始恶化,再经修理,又能恢复到正常的状态。但是,在这里——河北青县却发现了一个反常的数字。我们调查了10台175型柴油机在浇地作业中的标亩耗油量,其中使用一年的柴油机平均标亩耗油为1.15公斤,使用二年的为0.96公斤,使用三年的为0.83公斤。可以得出这样一个结论:新的机器不能发挥出最大的经济效益,而使用一二年之后才能使油耗下降。
Under normal circumstances, the new purchase of machinery according to the provisions of the run-in, after adjustment, will reach a good technical state, the use of a longer period of time, its power, economy began to deteriorate, and then repaired, but also restored Normal state. However, here - Hebei Qingxian found an anomalous figure. We investigated the standard oil consumption of 10 175-type diesel engines during the irrigating operation. The average diesel fuel consumption for a year was 1.15 kg, 0.96 kg for two years and 0.83 kg for three years . It can be concluded that the new machine can not maximize the economic benefits, and use a year or two in order to reduce fuel consumption.
