              微耕機的整機空負荷磨合分析

              發動機空載磨合并檢查完畢后,即開始整機的空負荷磨合工作。整機空負荷磨合是在道路上和田間進行的,只用行走輪,不加載耕作機具。

              微耕機整機空負荷磨合的具體方法:左手握緊主離合器手柄,檢查離合是否正常,如不正常,調整主離合拉線;雙手握放轉向離合器手柄,檢查轉向是否靈活,如不靈活,調整轉向離合拉線;拉動主離合器操作桿到“離”的位置,在不加油的狀態下,檢查各排檔的檔位是否靈活到位,檢查并調整完畢后,把主離合器手柄拉到“離”的位置,先加油,后排檔,然后推動主離合器手柄到“合”的位置,微耕機行走;握緊左轉向離合器手柄,微耕機向左轉向行走,握緊右轉向離合器手柄,微耕機向右轉向行走.不論是主離合器,或者是轉向離合器,在分離時,要迅速、徹底結合時,要柔和平順。先采用低速前進檔運行1h,再采用快速前進檔運行1h,磨合中,經常觀察各部件是否工作正常,檢查發動機和變速箱有無漏油、漏氣、漏水現象,如發現故障,要及時停機排除。整機空負荷磨合完畢后,把主離合器手柄拉到“離”的位置,關閉油門和點火開關,微耕機熄火停機,磨合結束。
               
              磨合結束后,潤滑油中含有大量的金屬粉末,必須清洗,并更換潤滑油。趁熱放空汽油發動機曲軸箱內的機油,再加入0.50kg左右的汽油,在關閉點火開關和油門的狀態下,拉動啟動繩20-30次進行清洗,然后放空發動機曲軸箱內的汽油,再按規定加足新的機油。趁熱放空柴油發動機曲軸箱內的機油,再加入0.50kg左右的汽油或柴油,在關閉油門的狀態下,用手搖柄搖動曲軸20-30圈進行清洗,然后放空發動機曲軸箱內的柴油,再按規定加足新的機油。拆下機油濾清器,用清潔的汽油或柴油清洗后,再裝回機油濾清器。趁熱放空變速箱內的齒輪油,再加入1kg左右的汽油或柴油,在關閉點火開關和油門的狀態下,掛上低速檔,推動微耕機行走5-10min,然后放空變速箱內的汽油或柴油,再按規定加足新的齒輪油。
