一、老化机械要定期更换。目前,在排灌机械使用上,多数乡、村对已经需要更换的机械,不按时更换,认为修一修仍可用上几年,致使一些老化到了严重程度的机械仍长期运行使用。其结果耗能高,效益低。经在我县西三甲大队测试:小麦春灌时,同一眼井,同一地块,同一畦长,58年产“1140”型柴油机比78年产的“195”型柴油机亩次多耗油0.6公斤,马
First, the aging machinery to be replaced on a regular basis. At present, in the use of irrigation and drainage machinery, most townships and villages do not change machinery on time and need to be replaced. They think that repairs can still last for a few years, causing some aged machines to go on operating for a long time. The results of high energy consumption, low efficiency. In the county Xisan A group test: wheat spring irrigation, the same well, the same land, the same length, 58 annual output of “1140” type diesel engine than 78 annual output of “195” type diesel engine MU times more consumption of 0.6 kg ,horse
