車間除(chu)塵風機的工作原理

礦用(yong)除塵(chen)風(feng)(feng)機能吸走車間(jian)(jian)的(de)灰塵(chen)，防止人(ren)(ren)體的(de)吸入，有利(li)于(yu)人(ren)(ren)體健康。與一般離(li)心式通風(feng)(feng)機的(de)工作(zuo)(zuo)原理(li)基本相(xiang)同，當葉(xie)(xie)輪(lun)高速(su)旋(xuan)(xuan)轉(zhuan)時(shi)，葉(xie)(xie)輪(lun)中(zhong)(zhong)(zhong)各部分空(kong)(kong)氣(qi)(qi)也被(bei)帶動(dong)一起旋(xuan)(xuan)轉(zhuan)，此時(shi)，在(zai)(zai)葉(xie)(xie)輪(lun)中(zhong)(zhong)(zhong) 心處的(de)空(kong)(kong)氣(qi)(qi)因(yin)受離(li)心力(li)的(de)作(zuo)(zuo)用(yong)將(jiang)被(bei)拋向(xiang)葉(xie)(xie)輪(lun)的(de)邊緣(yuan)，在(zai)(zai)葉(xie)(xie)輪(lun)中(zhong)(zhong)(zhong) 心處便形(xing)成了真空(kong)(kong)，于(yu)是，外部的(de)空(kong)(kong)氣(qi)(qi)在(zai)(zai)壓(ya)(ya)差的(de)作(zuo)(zuo)用(yong)下，不斷地流入，補充到葉(xie)(xie)輪(lun)中(zhong)(zhong)(zhong) 心處，這樣(yang)就使風(feng)(feng)機具(ju)備了吸入空(kong)(kong)氣(qi)(qi)的(de)能力(li)。由于(yu)空(kong)(kong)氣(qi)(qi)在(zai)(zai)旋(xuan)(xuan)轉(zhuan)中(zhong)(zhong)(zhong)離(li)開葉(xie)(xie)輪(lun)葉(xie)(xie)片的(de)速(su)度(du)遠(yuan)遠(yuan)大于(yu)葉(xie)(xie)輪(lun)周圍空(kong)(kong)間(jian)(jian)的(de)氣(qi)(qi)流速(su)度(du)，這使得氣(qi)(qi)體在(zai)(zai)運動(dong)中(zhong)(zhong)(zhong)有部分動(dong)能轉(zhuan)變為靜(jing)(jing)壓(ya)(ya)能，在(zai)(zai)動(dong)能轉(zhuan)化為靜(jing)(jing)壓(ya)(ya)能的(de)過程中(zhong)(zhong)(zhong)，風(feng)(feng)機的(de)風(feng)(feng)罩空(kong)(kong)間(jian)(jian)呈(cheng)現正(zheng)壓(ya)(ya)，從而使風(feng)(feng)機具(ju)備將(jiang)氣(qi)(qi)體轉(zhuan)入導論(lun)中(zhong)(zhong)(zhong)的(de)能力(li)，并(bing)在(zai)(zai)導論(lun)中(zhong)(zhong)(zhong)再將(jiang)部分動(dong)能轉(zhuan)變為靜(jing)(jing)壓(ya)(ya)能，然后流入電(dian)機，同時(shi)給電(dian)機散熱(re)，然后經出口壓(ya)(ya)出。
