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， 混凝土泵電源(yuan)接(jie)通(tong)后，首(shou)次使(shi)用時應檢查電機(ji)的(de)轉向(xiang)(xiang)與電機(ji)標明的(de)轉向(xiang)(xiang)是否一(yi)致(zhi)，若轉向(xiang)(xiang)不一(yi)致(zhi)，必(bi)須(xu)馬上停(ting)機(ji)，調查轉換向(xiang)(xiang)后，方可新啟動。 警(jing)告：主(zhu)(zhu)回路未采(cai)用隔(ge)離接(jie)觸器，當電控(kong)箱(xiang)(xiang)內空(kong)氣開關合(he)上時，主(zhu)(zhu)電機(ji)線端仍有危(wei)險的(de)電壓(ya)存(cun)在。英雌，當電控(kong)箱(xiang)(xiang)內空(kong)氣開關QS接(jie)通(tong)后，禁止打(da)開控(kong)制器和主(zhu)(zhu)電機(ji)的(de)接(jie)觸接(jie)線盒檢修。如(ru)果在進(jin)行故障排除(chu)，測量等工作(zuo)時，部分電路必(bi)須(xu)帶電的(de)話，只能(neng)由專業維修人(ren)員，嚴格按(an)照有關安全(quan)條例采(cai)區(qu)適(shi)當的(de)方法(fa)來進(jin)行。

二、電控箱控制系統 主(zhu)(zhu)電(dian)機(ji)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)和(he)停止(zhi)(zhi)(zhi)均在電(dian)控(kong)(kong)箱(xiang)上操(cao)作(zuo)。將“控(kong)(kong)制(zhi)遙控(kong)(kong)”轉(zhuan)換開關旋到“控(kong)(kong)制(zhi)”位置，泵(beng)(beng)(beng)送進(jin)入(ru)電(dian)控(kong)(kong)箱(xiang)操(cao)作(zuo)狀態。 1、泵(beng)(beng)(beng)送啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)及(ji)停止(zhi)(zhi)(zhi) 為(wei)保(bao)(bao)證主(zhu)(zhu)電(dian)機(ji)正(zheng)常(chang)運(yun)轉(zhuan)，防止(zhi)(zhi)(zhi)帶載啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)，自動(dong)(dong)(dong)(dong)(dong)泵(beng)(beng)(beng)送只(zhi)有在主(zhu)(zhu)電(dian)機(ji)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)完畢后才能啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)。主(zhu)(zhu)電(dian)機(ji)不啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)或在啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)工程(cheng)中，按電(dian)控(kong)(kong)箱(xiang)面板上SB4泵(beng)(beng)(beng)送啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)按鈕無效。 按泵(beng)(beng)(beng)送停止(zhi)(zhi)(zhi)按鈕SB3，泵(beng)(beng)(beng)送停止(zhi)(zhi)(zhi)并為(wei)分配閥點(dian)(dian)動(dong)(dong)(dong)(dong)(dong)及(ji)主(zhu)(zhu)缸(gang)點(dian)(dian)動(dong)(dong)(dong)(dong)(dong)作(zuo)好準備。 2，手動(dong)(dong)(dong)(dong)(dong)反(fan)(fan)泵(beng)(beng)(beng) 當(dang)需要(yao)反(fan)(fan)泵(beng)(beng)(beng)工作(zuo)時，旋轉(zhuan)二位選擇開關SB10，即(ji)可(ke)(ke)實現反(fan)(fan)泵(beng)(beng)(beng)動(dong)(dong)(dong)(dong)(dong)作(zuo)。要(yao)停止(zhi)(zhi)(zhi)反(fan)(fan)泵(beng)(beng)(beng)只(zhi)需將SB10復位即(ji)可(ke)(ke)。 3，主(zhu)(zhu)缸(gang)點(dian)(dian)動(dong)(dong)(dong)(dong)(dong) 當(dang)自動(dong)(dong)(dong)(dong)(dong)泵(beng)(beng)(beng)送停止(zhi)(zhi)(zhi)時，旋轉(zhuan)SB10按鈕，關保(bao)(bao)持在點(dian)(dian)動(dong)(dong)(dong)(dong)(dong)位置，即(ji)可(ke)(ke)實現主(zhu)(zhu)缸(gang)點(dian)(dian)動(dong)(dong)(dong)(dong)(dong)；松開旋轉(zhuan)鈕自動(dong)(dong)(dong)(dong)(dong)復位，停止(zhi)(zhi)(zhi)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)。

三、有線遙控系統  當需要采(cai)用遙(yao)(yao)控(kong)操作時(shi)，必須將電(dian)(dian)控(kong)箱面板上“”控(kong)制遙(yao)(yao)按“旋(xuan)轉(zhuan)SB9置于遙(yao)(yao)控(kong)位(wei)置，并把遙(yao)(yao)控(kong)器上的電(dian)(dian)纜插頭(tou)與(yu)箱體(ti)上相應插座連好關(guan)(guan)鎖緊。在遙(yao)(yao)控(kong)盒上設有泵送(song)啟動、泵送(song)停止、正反泵防水開關(guan)(guan)，其控(kong)制功能與(yu)電(dian)(dian)控(kong)箱相應按鈕開關(guan)(guan)相同。
