At the same time , the function of measuring coal in every coal storage bunker and measuring coal before its entering into every boiler greatly improves productivity of the whole loading and unloading coal system . . on the aspect of operation technics of the loading and unloading coal system , this article analyzes factors which affect operation technics of coal - whippers , stacking conveyers and pusher tractors . no standardization in daily operation , low safety , long operation time and out of line among different machines reduces the efficiency of the loading and unloading coal system 卸煤操作工藝方面,主要分析了卸船機、堆取料機和推扒機在日常作業(yè)過程中影響作業(yè)工藝的因素,在日常作業(yè)過程中主要存在問題是無標準化作業(yè)要求,安全得不到保障,作業(yè)時間長,各作業(yè)機械之間配合差,從而影響整個卸煤系統(tǒng)的作業(yè)效率,本文通過對卸船機、堆取料機、推扒機作業(yè)流程的設計,規(guī)定了單個機械的作業(yè)程序,以及相互之間作業(yè)時的配合方法,使卸船機作業(yè)和堆場作業(yè)更規(guī)范化,同時,大大縮短卸船作業(yè)時間,提高了碼頭泊位利用率,減少機械作業(yè)時間,從而提高了整個輸煤系統(tǒng)的工作效率。
