电(dian)(dian)控电(dian)(dian)梯泵喷射系(xi)统的(de)工(gong)作过程分为以下几(ji)个阶段(duan):高(gao)(gao)(gao)速(su)磁(ci)溢(yi)(yi)(yi)(yi)流(liu)(liu)阀(fa)设(she)在单(dan)体(ti)泵的(de)储(chu)油(you)(you)(you)(you)端,溢(yi)(yi)(yi)(yi)流(liu)(liu)阀(fa)断电(dian)(dian)时(shi)(shi),回(hui)(hui)油(you)(you)(you)(you)道打(da)开,单(dan)体(ti)泵内(nei)的(de)柱塞即使(shi)已开始(shi)泵油(you)(you)(you)(you),也不能建立高(gao)(gao)(gao)压,只能当溢(yi)(yi)(yi)(yi)流(liu)(liu)阀(fa)通电(dian)(dian),回(hui)(hui)油(you)(you)(you)(you)油(you)(you)(you)(you)道关闭,油(you)(you)(you)(you)压才迅速(su)升高(gao)(gao)(gao),高(gao)(gao)(gao)压燃(ran)油(you)(you)(you)(you)经过一段(duan)很短的(de)高(gao)(gao)(gao)压油(you)(you)(you)(you)管进入喷油(you)(you)(you)(you)器(qi)使(shi)其喷油(you)(you)(you)(you),溢(yi)(yi)(yi)(yi)流(liu)(liu)阀(fa)断电(dian)(dian)时(shi)(shi),回(hui)(hui)油(you)(you)(you)(you)油(you)(you)(you)(you)道打(da)开,迅速(su)溢(yi)(yi)(yi)(yi)流(liu)(liu)卸压,喷油(you)(you)(you)(you)停止,电(dian)(dian)磁(ci)溢(yi)(yi)(yi)(yi)流(liu)(liu)阀(fa)通电(dian)(dian)的(de)持续(xu)时(shi)(shi)间(jian)决(jue)定了循(xun)环供油(you)(you)(you)(you)量(liang)

1充(chong)油(you)过程,当(dang)柱(zhu)塞下(xia)移时,喷(pen)(pen)射系统(tong)(tong)内部压(ya)(ya)力(li)将低(di)(di)于低(di)(di)压(ya)(ya)油(you)路的喷(pen)(pen)油(you)压(ya)(ya)力(li),此(ci)时低(di)(di)压(ya)(ya)系统(tong)(tong)燃油(you)将通(tong)过柱(zhu)塞套上的进油(you)口进入高(gao)压(ya)(ya)喷(pen)(pen)射系统(tong)(tong)

2旁通(tong)过程,当(dang)柱(zhu)塞(sai)上升,柱(zhu)塞(sai)腔压力上升,只要电(dian)磁阀(fa)处于(yu)断(duan)电(dian)状态,此(ci)时(shi)柱(zhu)塞(sai)腔中压力与(yu)进油(you)压力大(da)体相同,燃(ran)油(you)通(tong)过回流(liu)通(tong)路回到油(you)箱(xiang),受(shou)压燃(ran)油(you)经控制(zhi)阀(fa)旁通(tong)口高速(su)泄流(liu),回到低压系统(tong)
