一(yi)、概述
　　R1902 型電氣控制箱(xiang)，用于自(zi)動(dong)(dong)控(kong)制一套由U- ※※ AL 型環式電(dian)(dian)動(dong)(dong)潤(run)滑泵與補(bu)(bu)脂(zhi)泵組(zu)成(cheng)的(de)干油(you)(you)潤(run)滑系統，即在DEA-2L型電(dian)(dian)控(kong)箱(xiang)的(de)基礎上，增加(jia)了補(bu)(bu)脂(zhi)泵自(zi)動(dong)(dong)控(kong)制部分。能對系統中(zhong)的(de)供油(you)(you)點現實自(zi)動(dong)(dong)供油(you)(you)，供油(you)(you)完成(cheng)后(hou)，自(zi)動(dong)(dong)停(ting)止(zhi)(zhi)。油(you)(you)箱(xiang)中(zhong)液位低于一定限度(du)時，補(bu)(bu)脂(zhi)泵自(zi)動(dong)(dong)啟動(dong)(dong)，注滿油(you)(you)后(hou)，自(zi)動(dong)(dong)停(ting)止(zhi)(zhi)。　　控(kong)制箱(xiang)能發(fa)出(chu)“供油(you)(you)時間延長(chang)”、“加(jia)油(you)(you)泵超載”、“超負(fu)荷(he)運轉”等(deng)故(gu)障信(xin)號，箱(xiang)內設有一組(zu)外部接(jie)點，可向主機或主控(kong)室發(fa)送系統運轉狀況（停(ting)止(zhi)(zhi)、運轉、故(gu)障）信(xin)號。
