JSJR系列電機(jī)技術(shù)數(shù)據(jù)

1、JR、JS系列的電機(jī)是中型三相異步電動機(jī)，是我國50年代未60年代初統(tǒng)一設(shè)計(jì)的中型電動機(jī)，它分低壓和高壓兩部分，都是中型三相電動機(jī)的基本系列。 Y型系列三相電動機(jī)，是我國近年來研制成功的節(jié)能新型電機(jī)。JR、JS系列的電機(jī)基本淘汰被Y系列所取代。 功率相同即是容量相同，只是Y型系列電機(jī)體積比JR、JS系列電機(jī)體積小JR系列電動機(jī)JR系列電動機(jī)為驅(qū)動各種不同機(jī)械之用，如通風(fēng)機(jī)、壓縮機(jī)、水泵、破碎機(jī)、切削機(jī)床、榆樹機(jī)械及其他設(shè)備等。 本系列電動機(jī)一般為為自通風(fēng)防護(hù)式。 電動機(jī)應(yīng)在海拔高度不超過1,000米，使用地點(diǎn)空氣溫度不高于+40的室內(nèi)正常工作，溫升限度符合國家標(biāo)準(zhǔn)GB/T755-2000的規(guī)定

2、。 本系列電動機(jī)符合機(jī)械工業(yè)部部頒標(biāo)準(zhǔn)JB563-64和JB564-64的規(guī)定。 本系列電動機(jī)共分為五個機(jī)座號，即11、12、13、14及15號機(jī)座。 例如： （1）JS147-6表示鼠籠轉(zhuǎn)子型異步電動機(jī)，14號機(jī)座，定子鐵心長度為7號，6極。 （2）JR147-10表示繞線轉(zhuǎn)子型異步電動機(jī)，14號機(jī)座，定子鐵心長度為7號，10極一、JS、JR系列概述J系列中型電機(jī)可驅(qū)動各種不同的機(jī)械，如通風(fēng)機(jī)、壓縮機(jī)、水泵、破碎機(jī)、球磨機(jī)、要削機(jī)床、運(yùn)輸機(jī)械及其他設(shè)備，可供煤礦、機(jī)械工業(yè)、發(fā)電廠及各種工礦企業(yè)中作原動機(jī)用。JS系列為鼠籠轉(zhuǎn)子三相異步電機(jī)。JR系列為繞線轉(zhuǎn)子三相異步電機(jī)。JS系列電機(jī)符合部頒機(jī)

3、準(zhǔn)JB563-64技術(shù)條件的規(guī)定。JR系列電機(jī)符合部頒機(jī)準(zhǔn)JB564-64技術(shù)條件的規(guī)定。本系列電機(jī)為防護(hù)式。根據(jù)用戶需要也可制成管道通風(fēng)式。防護(hù)式電機(jī)應(yīng)裝置在海拔高度不超過1KM，周圍空氣溫度不高于+40，不低于0，空氣清潔，無酸、堿等腐蝕性氣體的室內(nèi)。電機(jī)不允許在含有爆炸性氣體或塵埃較多的環(huán)境中工作。當(dāng)電機(jī)周圍空氣的溫度超過上述規(guī)定或空氣不清潔時，應(yīng)采用管道通用方式。此時，通入電機(jī)兩端的冷卻空氣溫度應(yīng)為040并且應(yīng)保證管道和電機(jī)內(nèi)部的空氣壓力高于周圍空氣的壓力，必要時應(yīng)加裝鼓風(fēng)機(jī)、濾塵器等。JS系列鼠籠型電機(jī)允許全電壓直接起動。最初起動轉(zhuǎn)矩和最初起動電流數(shù)值分別與額定值之比，如表3所示。如

4、用戶的電網(wǎng)不允許全電壓直接起動時，可以采用降低電壓起動。但此時起動轉(zhuǎn)矩將與起動電壓成平方關(guān)系降低。JR系列電機(jī)在起動時必須預(yù)先在轉(zhuǎn)子回路內(nèi)接入起動變阻器。不允許將轉(zhuǎn)子繞組直接短接起動。二、結(jié)構(gòu)簡述電機(jī)的其本安裝型式機(jī)座帶底腳臥式安裝，所有型號的電機(jī)都可采用聯(lián)軸器與被驅(qū)動機(jī)械聯(lián)接。電機(jī)采用兩側(cè)對稱的徑向通風(fēng)系統(tǒng)，冷卻空氣自兩側(cè)端蓋的進(jìn)風(fēng)口進(jìn)入，一部分經(jīng)過電機(jī)轉(zhuǎn)子上的風(fēng)扇或風(fēng)葉片吹過定子線圈的端接部分，另一部分空氣經(jīng)過轉(zhuǎn)子鐵心中的徑向通風(fēng)槽，然后由機(jī)座側(cè)面的出風(fēng)口逸出。管道通風(fēng)式電機(jī)的通風(fēng)系統(tǒng)與上述相同。電機(jī)的軸承采用滾動軸承。所用的軸承牌號見表1，軸承潤滑脂牌號為鋰基潤滑脂ZL-3。表1機(jī)座號F
