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)源接通(tong)后(hou)，首(shou)次使用(yong)(yong)時應檢查電(dian)機(ji)的轉(zhuan)(zhuan)向與電(dian)機(ji)標(biao)明的轉(zhuan)(zhuan)向是(shi)否一致(zhi)，若轉(zhuan)(zhuan)向不(bu)一致(zhi)，必須(xu)馬上停機(ji)，調查轉(zhuan)(zhuan)換向后(hou)，方(fang)可(ke)新啟動。 警告(gao)：主回(hui)路(lu)未采用(yong)(yong)隔離接觸(chu)器(qi)(qi)，當電(dian)控(kong)箱內空氣(qi)開關合(he)上時，主電(dian)機(ji)線端仍有危(wei)險(xian)的電(dian)壓存(cun)在。英雌，當電(dian)控(kong)箱內空氣(qi)開關QS接通(tong)后(hou)，禁(jin)止(zhi)打開控(kong)制器(qi)(qi)和主電(dian)機(ji)的接觸(chu)接線盒檢修。如果(guo)在進(jin)行(xing)故障排除，測量等工作時，部分電(dian)路(lu)必須(xu)帶電(dian)的話，只能由專業(ye)維修人員，嚴(yan)格按照有關安全條例采區(qu)適當的方(fang)法來進(jin)行(xing)。

二、電控箱控制系統 主(zhu)電(dian)(dian)(dian)機啟(qi)(qi)(qi)(qi)動(dong)(dong)和停(ting)止(zhi)均在電(dian)(dian)(dian)控(kong)(kong)箱上操作(zuo)。將“控(kong)(kong)制(zhi)遙控(kong)(kong)”轉(zhuan)換開關旋到(dao)“控(kong)(kong)制(zhi)”位(wei)置，泵(beng)(beng)(beng)(beng)送(song)進入電(dian)(dian)(dian)控(kong)(kong)箱操作(zuo)狀態。 1、泵(beng)(beng)(beng)(beng)送(song)啟(qi)(qi)(qi)(qi)動(dong)(dong)及停(ting)止(zhi) 為(wei)保證主(zhu)電(dian)(dian)(dian)機正常運轉(zhuan)，防(fang)止(zhi)帶載啟(qi)(qi)(qi)(qi)動(dong)(dong)，自動(dong)(dong)泵(beng)(beng)(beng)(beng)送(song)只有在主(zhu)電(dian)(dian)(dian)機啟(qi)(qi)(qi)(qi)動(dong)(dong)完畢后才能啟(qi)(qi)(qi)(qi)動(dong)(dong)。主(zhu)電(dian)(dian)(dian)機不啟(qi)(qi)(qi)(qi)動(dong)(dong)或在啟(qi)(qi)(qi)(qi)動(dong)(dong)工程中，按(an)電(dian)(dian)(dian)控(kong)(kong)箱面(mian)板上SB4泵(beng)(beng)(beng)(beng)送(song)啟(qi)(qi)(qi)(qi)動(dong)(dong)按(an)鈕(niu)無效。 按(an)泵(beng)(beng)(beng)(beng)送(song)停(ting)止(zhi)按(an)鈕(niu)SB3，泵(beng)(beng)(beng)(beng)送(song)停(ting)止(zhi)并為(wei)分(fen)配閥點(dian)動(dong)(dong)及主(zhu)缸(gang)點(dian)動(dong)(dong)作(zuo)好準備。 2，手動(dong)(dong)反(fan)泵(beng)(beng)(beng)(beng) 當需要反(fan)泵(beng)(beng)(beng)(beng)工作(zuo)時，旋轉(zhuan)二位(wei)選擇開關SB10，即(ji)可實現反(fan)泵(beng)(beng)(beng)(beng)動(dong)(dong)作(zuo)。要停(ting)止(zhi)反(fan)泵(beng)(beng)(beng)(beng)只需將SB10復位(wei)即(ji)可。 3，主(zhu)缸(gang)點(dian)動(dong)(dong) 當自動(dong)(dong)泵(beng)(beng)(beng)(beng)送(song)停(ting)止(zhi)時，旋轉(zhuan)SB10按(an)鈕(niu)，關保持在點(dian)動(dong)(dong)位(wei)置，即(ji)可實現主(zhu)缸(gang)點(dian)動(dong)(dong)；松開旋轉(zhuan)鈕(niu)自動(dong)(dong)復位(wei)，停(ting)止(zhi)啟(qi)(qi)(qi)(qi)動(dong)(dong)。

三、有線遙控系統 當需要采用遙(yao)控(kong)(kong)(kong)操作時，必須將(jiang)電(dian)控(kong)(kong)(kong)箱面板上(shang)“”控(kong)(kong)(kong)制遙(yao)按(an)(an)“旋轉SB9置于遙(yao)控(kong)(kong)(kong)位置，并把遙(yao)控(kong)(kong)(kong)器上(shang)的(de)電(dian)纜插(cha)頭(tou)與(yu)(yu)箱體上(shang)相應(ying)插(cha)座連好關鎖緊。在遙(yao)控(kong)(kong)(kong)盒上(shang)設有(you)泵(beng)送啟動、泵(beng)送停止、正反(fan)泵(beng)防水開(kai)關，其控(kong)(kong)(kong)制功能與(yu)(yu)電(dian)控(kong)(kong)(kong)箱相應(ying)按(an)(an)鈕開(kai)關相同。
