直流(liu)調速器是什么?有什么應用?下面，小編就為大家介紹一(yi)下：

　　一、什么是(shi)直(zhi)(zhi)流調速器(qi)?直(zhi)(zhi)流調速器(qi)就是(shi)調節直(zhi)(zhi)流電(dian)動(dong)機(ji)速度的(de)設(she)備, 由于(yu)直(zhi)(zhi)流電(dian)動(dong)機(ji)具有低(di)轉速大(da)力矩(ju)的(de)特(te)點,是(shi)交流電(dian)動(dong)機(ji)無法(fa)取代的(de), 因此調節直(zhi)(zhi)流電(dian)動(dong)機(ji)速度的(de)設(she)備—直(zhi)(zhi)流調速器(qi),具有廣闊的(de)應用天地。

　　二、什么場合下(xia)(xia)要(yao)(yao)選(xuan)擇使用(yong)(yong)直(zhi)流調(diao)(diao)速器(qi)? 下(xia)(xia)列場合需(xu)(xu)要(yao)(yao)使用(yong)(yong)直(zhi)流調(diao)(diao)速器(qi): 1、需(xu)(xu)要(yao)(yao)較(jiao)寬(kuan)的調(diao)(diao)速范圍。 2、需(xu)(xu)要(yao)(yao)較(jiao)快的動(dong)(dong)態響(xiang)應過(guo)程(cheng)。 3、加、減(jian)速時需(xu)(xu)要(yao)(yao)自(zi)(zi)動(dong)(dong)平滑的過(guo)渡過(guo)程(cheng)。 4、需(xu)(xu)要(yao)(yao)低(di)速運轉時力矩大(da)。 5、需(xu)(xu)要(yao)(yao)較(jiao)好的挖(wa)土機特性(xing)，能(neng)將過(guo)載電(dian)(dian)流自(zi)(zi)動(dong)(dong)限(xian)止在設(she)定電(dian)(dian)流上(shang)。 以上(shang)五點也是直(zhi)流調(diao)(diao)速器(qi)的應用(yong)(yong)特點。

　　三、直流調速器應用(yong): 直流調速器在數控機(ji)床、造紙(zhi)印(yin)刷、紡織印(yin)染、光纜線纜設(she)(she)備(bei)(bei)(bei)(bei)(bei)、包(bao)裝機(ji)械(xie)(xie)、電(dian)(dian)工機(ji)械(xie)(xie)、食品加工機(ji)械(xie)(xie)、橡膠機(ji)械(xie)(xie)、生物(wu)設(she)(she)備(bei)(bei)(bei)(bei)(bei)、印(yin)制電(dian)(dian)路板設(she)(she)備(bei)(bei)(bei)(bei)(bei)、實(shi)驗設(she)(she)備(bei)(bei)(bei)(bei)(bei)、焊接切割、輕工機(ji)械(xie)(xie)、物(wu)流輸送(song)設(she)(she)備(bei)(bei)(bei)(bei)(bei)、機(ji)車(che)車(che)輛、醫(yi)設(she)(she)備(bei)(bei)(bei)(bei)(bei)、通(tong)訊(xun)設(she)(she)備(bei)(bei)(bei)(bei)(bei)、雷(lei)達設(she)(she)備(bei)(bei)(bei)(bei)(bei)、衛(wei)星地面(mian)接受系統(tong)等 廣泛應用(yong)。
