混凝土泵主(zhu)電(dian)(dian)(dian)機(ji)達不(bu)(bu)到規(gui)定(ding)轉(zhuan)(zhuan)速(su)按(an)主(zhu)電(dian)(dian)(dian)機(ji)起(qi)動(dong)(dong)按(an)鈕，電(dian)(dian)(dian)機(ji)可(ke)運轉(zhuan)(zhuan)，但達不(bu)(bu)到規(gui)定(ding)轉(zhuan)(zhuan)速(su)，且由星形接法(fa)轉(zhuan)(zhuan)換為(wei)三角形接法(fa)時(shi)自動(dong)(dong)停(ting)機(ji)。首先(xian)檢查(cha)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓是(shi)否正(zheng)常，變壓器容量(liang)是(shi)否足(zu)(zu)夠（變壓器容量(liang)一(yi)(yi)般為(wei)計(ji)(ji)算(suan)負(fu)荷(he)的(de)(de)1.15倍），再通(tong)過計(ji)(ji)算(suan)和(he)測量(liang)起(qi)動(dong)(dong)時(shi)電(dian)(dian)(dian)壓確定(ding)供電(dian)(dian)(dian)線路(lu)線徑是(shi)否滿足(zu)(zu)要求，保證電(dian)(dian)(dian)壓降(jiang)在規(gui)定(ding)的(de)(de)范圍之內(nei)（線路(lu)上(shang)允許電(dian)(dian)(dian)壓降(jiang)一(yi)(yi)般不(bu)(bu)大(da)于(yu)5%），如果起(qi)動(dong)(dong)時(shi)電(dian)(dian)(dian)壓降(jiang)太大(da)，可(ke)適當(dang)加大(da)線徑。液壓系統的(de)(de)操作不(bu)(bu)當(dang)和(he)故障也會造成(cheng)起(qi)動(dong)(dong)困(kun)難。

開機前，首(shou)先應檢查(cha)水泵、攪拌馬達操作(zuo)手柄是否處(chu)于中位，泵送按(an)鈕是否關閉。若還不(bu)能起動就要檢查(cha)控(kong)制主(zhu)油泵壓力的電磁閥是否正(zheng)常，保(bao)證起動時主(zhu)油泵處(chu)于泄荷(he)狀態。
