微耕机整机空负荷磨合
时间:2013-03-11 来源:本站 作者:管理员

发动机空载磨合并检查完毕后,即开始整机的空负荷磨合工作。整机空负荷磨合是在道路上和田间进行的,只用行走轮,不加载耕作机具。微耕机整机空负荷磨合的具体方法如下:

 
左手握紧主离合器手柄,检查离合是否正常,如不正常,调整主离合拉线;双手握放转向离合器手柄,检查转向是否灵活,如不灵活,调整转向离合拉线;拉动主离合器操作杆到“离”的位置,在不加油的状态下,检查各排档的档位是否灵活到位;检查并调整完毕后,把主离合器手柄拉到“离”的位置,先加油,后排档,然后推动主离合器手柄到“合”的位置,微耕机行走;握紧左转向离合器手柄,微耕机向左转向行走,握紧右转向离合器手柄,微耕机向右转向行走。不论是主离合器或者是转向离合器在分离时要迅速、彻底结合时要柔和平顺。先采用低速前进档运行1h,再采用快速前进档运行1h;磨合中经常观察各部件是否工作正常,检查发动机和变速箱有无漏油、漏气、漏水现象,如发现故障,要及时停机排除。整机空负荷磨合完毕后,把主离合器手柄拉到“离”的位置,关闭油门和点火开关,微耕机熄火停机,磨合结束。
 
磨合结束后,润滑油中含有大量的金属粉末,必须清洗,并更换润滑油。趁热放空汽油发动机曲轴箱内的机油,再加入0.50kg左右的汽油,在关闭点火开关和油门的状态下,拉动启动绳20-30次进行清洗,然后放空发动机曲轴箱内的汽油,再按规定加足新的机油。趁热放空柴油发动机曲轴箱内的机油,再加入0.50kg左右的汽油或柴油,在关闭油门的状态下,用手摇柄摇动曲轴20-30圈进行清洗,然后放空发动机曲轴箱内的柴油,再按规定加足新的机油。拆下机油滤清器,用清洁的汽油或柴油清洗后,再装回机油滤清器。趁热放空变速箱内的齿轮油,再加入1kg左右的汽油或柴油,在关闭点火开关和油门的状态下,挂上低速档,推动微耕机行走5-10min,然后放空变速箱内的汽油或柴油,再按规定加足新的齿轮油。
