1. 變頻方案的提出
我(wo)廠(chang)催(cui)化(hua)劑(ji)車(che)間(jian)鋰(li)渣(zha)回(hui)收(shou)裝(zhuang)置(zhi)有(you)一(yi)台(tai)離(li)心(xin)式(shi)甩(shuai)幹(gan)機(ji)，其(qi)工(gong)作(zuo)原(yuan)理(li)如(ru)同(tong)家(jia)用(yong)洗(xi)衣(yi)機(ji)裏(li)的(de)甩(shuai)幹(gan)機(ji)，專(zhuan)門(men)負(fu)責(ze)將(jiang)含(han)有(you)較(jiao)多(duo)水(shui)分(fen)的(de)產(chan)品(pin)碳(tan)酸(suan)鋰(li)脫(tuo)水(shui)幹(gan)燥(zao)。該(gai)甩(shuai)幹(gan)機(ji)原(yuan)配(pei)備(bei)4極異步電機5.5kW，甩幹桶的轉速約1200r/min，但甩幹效果不理想。後采用提高轉速（1600r/min）及增大電機功率（7.5kW）方法，雖然脫水效果好了，電機卻常因過載而跳閘。
經檢查測量，電機在起動後，其運行電流達30A，維持約2min，然後電流下降，並穩定在10Azuoyou。zheshiyinweidianjiqidongchuqi，chanpinhanshuilianggao，yincifuzaizhong，dianjiyunxingdianliuyeda，jingtuoshuihou，fuzaijianxiao，dianjiyunxingdianliuyejiujianxiao。shijishang，dianjiguozaizhishizaichanpinhanshuiliangjiaogaodeyiduanshijiannei。womenshexiang：ruguonengcaiyongbianpinqishidianjizaichanpinhanshuiliangjiaogaodeyiduanshijiannei，yijiaodidezhuansuyunzhuan，shiqixianxingtuoquyibufenshui，dangqifuzaijianxiaohouzaitigaodianjizhuansu；或(huo)適(shi)當(dang)延(yan)長(chang)電(dian)機(ji)的(de)起(qi)動(dong)過(guo)程(cheng)，在(zai)電(dian)機(ji)較(jiao)長(chang)的(de)起(qi)動(dong)過(guo)程(cheng)中(zhong)，先(xian)將(jiang)產(chan)品(pin)脫(tuo)去(qu)部(bu)分(fen)水(shui)，然(ran)後(hou)電(dian)機(ji)進(jin)入(ru)正(zheng)常(chang)運(yun)行(xing)，保(bao)證(zheng)脫(tuo)水(shui)效(xiao)果(guo)。我(wo)們(men)采(cai)用(yong)了(le)富(fu)士(shi)變(bian)頻(pin)器(qi)，用(yong)延(yan)長(chang)電(dian)機(ji)起(qi)動(dong)時(shi)間(jian)的(de)方(fang)案(an)，這(zhe)樣(yang)不(bu)必(bi)重(zhong)放(fang)控(kong)製(zhi)線(xian)，還(hai)可(ke)利(li)用(yong)原(yuan)來(lai)的(de)電(dian)機(ji)控(kong)製(zhi)按(an)鈕(niu)。 2. 存在問題的改進
