一、動力控制系統 三民重科小型混凝土泵采用380V、50Hz三相交流電源，采用了星一三角啟動， 混凝土泵電(dian)(dian)源接(jie)(jie)通(tong)后(hou)，首次使用時(shi)應檢(jian)(jian)查電(dian)(dian)機(ji)的(de)轉向(xiang)與電(dian)(dian)機(ji)標明(ming)的(de)轉向(xiang)是否一(yi)(yi)致，若(ruo)轉向(xiang)不一(yi)(yi)致，必須馬(ma)上(shang)(shang)停機(ji)，調查轉換向(xiang)后(hou)，方可新啟動。 警告：主回路未采(cai)用隔離接(jie)(jie)觸(chu)器(qi)，當(dang)電(dian)(dian)控(kong)(kong)箱內空氣(qi)(qi)開關(guan)合上(shang)(shang)時(shi)，主電(dian)(dian)機(ji)線端仍有危險的(de)電(dian)(dian)壓存在(zai)。英(ying)雌(ci)，當(dang)電(dian)(dian)控(kong)(kong)箱內空氣(qi)(qi)開關(guan)QS接(jie)(jie)通(tong)后(hou)，禁止打(da)開控(kong)(kong)制器(qi)和主電(dian)(dian)機(ji)的(de)接(jie)(jie)觸(chu)接(jie)(jie)線盒檢(jian)(jian)修。如果在(zai)進(jin)行故障(zhang)排除，測量等工(gong)作時(shi)，部(bu)分電(dian)(dian)路必須帶(dai)電(dian)(dian)的(de)話，只能由專(zhuan)業維修人員(yuan)，嚴格按照有關(guan)安全條例采(cai)區適當(dang)的(de)方法(fa)來進(jin)行。

二、電控箱控制系統 主(zhu)(zhu)電機(ji)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)和(he)停(ting)止均在(zai)電控箱上操(cao)作(zuo)(zuo)(zuo)。將(jiang)“控制遙控”轉換開關(guan)旋(xuan)到“控制”位置(zhi)，泵(beng)送(song)進入電控箱操(cao)作(zuo)(zuo)(zuo)狀(zhuang)態。 1、泵(beng)送(song)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)及停(ting)止 為保證主(zhu)(zhu)電機(ji)正常(chang)運轉，防止帶載(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)，自動(dong)(dong)(dong)(dong)(dong)泵(beng)送(song)只有(you)在(zai)主(zhu)(zhu)電機(ji)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)完(wan)畢后才能啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)。主(zhu)(zhu)電機(ji)不啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)或在(zai)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)工程中，按(an)電控箱面板上SB4泵(beng)送(song)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)按(an)鈕無效。 按(an)泵(beng)送(song)停(ting)止按(an)鈕SB3，泵(beng)送(song)停(ting)止并為分配閥(fa)點動(dong)(dong)(dong)(dong)(dong)及主(zhu)(zhu)缸(gang)點動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)好(hao)準(zhun)備。 2，手動(dong)(dong)(dong)(dong)(dong)反(fan)泵(beng) 當(dang)需要反(fan)泵(beng)工作(zuo)(zuo)(zuo)時，旋(xuan)轉二位選擇開關(guan)SB10，即(ji)可實(shi)現反(fan)泵(beng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)。要停(ting)止反(fan)泵(beng)只需將(jiang)SB10復(fu)位即(ji)可。 3，主(zhu)(zhu)缸(gang)點動(dong)(dong)(dong)(dong)(dong) 當(dang)自動(dong)(dong)(dong)(dong)(dong)泵(beng)送(song)停(ting)止時，旋(xuan)轉SB10按(an)鈕，關(guan)保持(chi)在(zai)點動(dong)(dong)(dong)(dong)(dong)位置(zhi)，即(ji)可實(shi)現主(zhu)(zhu)缸(gang)點動(dong)(dong)(dong)(dong)(dong)；松開旋(xuan)轉鈕自動(dong)(dong)(dong)(dong)(dong)復(fu)位，停(ting)止啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)。

三、有線遙控系統 當需要采用遙(yao)控(kong)操作時，必須(xu)將電控(kong)箱(xiang)面板上“”控(kong)制遙(yao)按“旋轉SB9置于遙(yao)控(kong)位(wei)置，并(bing)把遙(yao)控(kong)器上的(de)電纜插(cha)頭與(yu)箱(xiang)體(ti)上相(xiang)(xiang)應(ying)插(cha)座連好(hao)關鎖緊。在遙(yao)控(kong)盒上設有泵送啟動、泵送停(ting)止、正反泵防水開關，其控(kong)制功能與(yu)電控(kong)箱(xiang)相(xiang)(xiang)應(ying)按鈕開關相(xiang)(xiang)同。
