哪些原因(yin)會導致干(gan)油(you)泵(beng)(beng)(beng)出現(xian)著(zhu)火(huo)現(xian)象呢？1、干(gan)油(you)泵(beng)(beng)(beng)內部短(duan)(duan)路：當繞(rao)組(zu)(zu)受(shou)潮、絕緣老化、過電(dian)(dian)(dian)壓(ya)擊穿及機(ji)(ji)(ji)(ji)械(xie)損(sun)傷等時(shi)(shi)(shi)(shi)，會致使絕緣破裂(lie)損(sun)壞(huai)，造(zao)成相間(jian)、匝間(jian)或對地(di)短(duan)(duan)路，使干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)溫(wen)度(du)急劇上(shang)(shang)升(sheng)，乃至“打火(huo)”放電(dian)(dian)(dian)，引(yin)起火(huo)災(zai)。2、缺(que)相運行(xing)：三相異步干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)缺(que)相運行(xing)時(shi)(shi)(shi)(shi)，若是(shi)(shi)在額定負載(zai)下，其電(dian)(dian)(dian)流增(zeng)大為額定值(zhi)的(de)(de)1.73倍(bei);若在堵轉(zhuan)狀態下啟(qi)動(dong)(dong)干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)啟(qi)動(dong)(dong)電(dian)(dian)(dian)流是(shi)(shi)額定值(zhi)的(de)(de)4~7倍(bei)。上(shang)(shang)述時(shi)(shi)(shi)(shi)間(jian)過長，繞(rao)組(zu)(zu)均會因(yin)過熱(re)而(er)(er)燒毀起火(huo)。3、干(gan)油(you)泵(beng)(beng)(beng)頻(pin)繁(fan)啟(qi)動(dong)(dong)：每次干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)啟(qi)動(dong)(dong)時(shi)(shi)(shi)(shi)都要承受(shou)堵轉(zhuan)電(dian)(dian)(dian)流的(de)(de)沖擊，若在短(duan)(duan)時(shi)(shi)(shi)(shi)間(jian)內連續多次啟(qi)動(dong)(dong)，則繞(rao)組(zu)(zu)由于溫(wen)度(du)急劇升(sheng)高而(er)(er)燃燒著(zhu)火(huo)。4、干(gan)油(you)泵(beng)(beng)(beng)接(jie)觸(chu)不(bu)良(liang)：當干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)內部及外部接(jie)線松動(dong)(dong)，導致接(jie)觸(chu)不(bu)良(liang)時(shi)(shi)(shi)(shi)，接(jie)觸(chu)電(dian)(dian)(dian)阻(zu)增(zeng)大，致使接(jie)頭過熱(re)，甚至“打火(huo)”放電(dian)(dian)(dian)，引(yin)起繞(rao)組(zu)(zu)絕緣及四周可燃物體燃燒。5、鐵芯短(duan)(duan)路：干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)鐵芯因(yin)質(zhi)量(liang)不(bu)佳或制造(zao)工藝的(de)(de)緣故，鐵芯短(duan)(duan)路，渦流損(sun)耗明顯增(zeng)大導致鐵芯過熱(re)，而(er)(er)使干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)著(zhu)火(huo)。6、干(gan)油(you)泵(beng)(beng)(beng)機(ji)(ji)(ji)(ji)械(xie)性堵轉(zhuan)：當干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)安裝不(bu)良(liang)或有異物進(jin)入時(shi)(shi)(shi)(shi)，以及軸承潤(run)(run)(run)滑(hua)(hua)油(you)不(bu)足(zu)或潤(run)(run)(run)滑(hua)(hua)油(you)臟(zang)污而(er)(er)將轉(zhuan)子卡(ka)住(zhu)，或所拖(tuo)動(dong)(dong)的(de)(de)機(ji)(ji)(ji)(ji)械(xie)被(bei)卡(ka)住(zhu)，致使干(gan)油(you)泵(beng)(beng)(beng)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)流急劇增(zeng)大，造(zao)成繞(rao)組(zu)(zu)溫(wen)升(sheng)過高而(er)(er)著(zhu)火(huo)。山東電(dian)(dian)(dian)動(dong)(dong)潤(run)(run)(run)滑(hua)(hua)泵(beng)(beng)(beng)價格是(shi)(shi)多少？寧夏(xia)通用(yong)電(dian)(dian)(dian)動(dong)(dong)潤(run)(run)(run)滑(hua)(hua)泵(beng)(beng)(beng)供應商
