Z2直流电机维修

Z2系列电机为一般工业用直流电机维修,其(qi)电(dian)动(dong)机适(shi)用(yong)于恒(heng)功率调速范围不大于1:2,过载(zai)能力不大于1.5倍(bei)额(e)定转矩的电(dian)力拖动(dong),也可(ke)用(yong)于金属切削机床、造纸、染织、印(yin)刷、水泥(ni)等工业。发电(dian)机可(ke)作动(dong)力电(dian)源,照(zhao)明或(huo)其(qi)他恒(heng)压供电(dian),其(qi)中调压发电(dian)机并可(ke)适(shi)用(yong)于大型蓄电(dian)池(chi)的充(chong)电(dian)及浮充(chong)之用(yong)。

为适(shi)(shi)应大范围(wei)(wei)的(de)(de)恒转(zhuan)矩(ju)(ju)调(diao)压调(diao)速(su)(su)及精(jing)确的(de)(de)速(su)(su)度(du)控(kong)制(zhi)(zhi),Z2系列发(fa)展了强风(feng)及强风(feng)带测速(su)(su)机(ji)(ji)(ji)(ji)的(de)(de)派生结构(gou),其电(dian)(dian)气规格与Z2系列电(dian)(dian)动机(ji)(ji)(ji)(ji)完全一(yi)致。但带有骑式鼓(gu)风(feng)机(ji)(ji)(ji)(ji)或兼(jian)带鼓(gu)风(feng)机(ji)(ji)(ji)(ji)与测速(su)(su)发(fa)电(dian)(dian)机(ji)(ji)(ji)(ji)的(de)(de)Z2电(dian)(dian)机(ji)(ji)(ji)(ji),结构(gou)紧(jin)凑,可(ke)(ke)长期在低速(su)(su)下运转(zhuan),更进(jin)一(yi)步(bu)发(fa)挥了直(zhi)流(liu)电(dian)(dian)机(ji)(ji)(ji)(ji)调(diao)速(su)(su)范围(wei)(wei)广,速(su)(su)度(du)控(kong)制(zhi)(zhi)精(jing)确的(de)(de)优点。配合电(dian)(dian)动机(ji)(ji)(ji)(ji)恒转(zhuan)矩(ju)(ju)调(diao)速(su)(su)的(de)(de)需(xu)要,Z2系列发(fa)电(dian)(dian)机(ji)(ji)(ji)(ji)可(ke)(ke)制(zhi)(zhi)成各种励(li)(li)磁电(dian)(dian)压的(de)(de)他励(li)(li)发(fa)电(dian)(dian)机(ji)(ji)(ji)(ji)以(yi)便(bian)于(yu)调(diao)压,励(li)(li)磁电(dian)(dian)压根(gen)据不(bu)同的(de)(de)励(li)(li)磁电(dian)(dian)源可(ke)(ke)以(yi)是110V,220V,也可(ke)(ke)以(yi)是其他合适(shi)(shi)的(de)(de)电(dian)(dian)压。

此外Z2系列为(wei)适应其他各种不(bu)同的(de)特殊需要(yao),还派生了另外一(yi)些特殊规格:

1、ZT2广调(diao)速(su)电(dian)(dian)动机:电(dian)(dian)动机的(de)(de)恒(heng)(heng)功率调(diao)磁(ci)调(diao)速(su)范围为1:3及1:4,对恒(heng)(heng)电(dian)(dian)压(ya)电(dian)(dian)网(wang)供电(dian)(dian)而(er)又需(xu)要较(jiao)宽(kuan)的(de)(de)调(diao)速(su)范围的(de)(de)场合提供了(le)方(fang)便。为减(jian)少高速(su)时的(de)(de)通(tong)风(feng)(feng)损耗,7号机座以(yi)上的(de)(de)ZT2一般(ban)均为强(qiang)迫通(tong)风(feng)(feng)的(de)(de)形(xing)式。

2、ZT2特殊电(dian)(dian)(dian)(dian)压(ya)电(dian)(dian)(dian)(dian)机(ji):额(e)定(ding)电(dian)(dian)(dian)(dian)压(ya)为180V,340V及440V的电(dian)(dian)(dian)(dian)动机(ji)适用于单(dan)相及三相可控硅电(dian)(dian)(dian)(dian)源(yuan)供电(dian)(dian)(dian)(dian)。额(e)定(ding)电(dian)(dian)(dian)(dian)压(ya)为275V及460V的发电(dian)(dian)(dian)(dian)机(ji)可用作矿井牵引拖动的电(dian)(dian)(dian)(dian)源(yuan)及其(qi)他(ta)需要(yao)特殊电(dian)(dian)(dian)(dian)压(ya)电(dian)(dian)(dian)(dian)源(yuan)的场合。

3、ZO2封(feng)闭电(dian)机:为全(quan)封(feng)闭,适用于特殊的,需要防尘(chen)的工作(zuo)环境。

4、根(gen)据(ju)特殊需(xu)要(yao),Z2系列(lie)还可(ke)(ke)派(pai)生带补偿绕组的电(dian)动(dong)机(ji)(ji)和发电(dian)机(ji)(ji),此(ci)时过载倍数(shu)可(ke)(ke)增加至2.5倍额(e)定转矩左(zuo)右,电(dian)枢回路时间常数(shu)亦(yi)可(ke)(ke)减(jian)少,适用于大功(gong)率伺(si)服系统或(huo)需(xu)要(yao)较大过载转矩的场合。目前8至11号机(ji)(ji)座已有部分(fen)规格,如有需(xu)要(yao),可(ke)(ke)继续(xu)发展(zhan)。

上述四种特殊(shu)规格,其外形尺(chi)寸,惯量距,重量与同(tong)机(ji)座(zuo)的Z2一致。
