隨著企業生產的需要，目前空壓機的使用范圍越來越廣，人們對空壓機的性能要求也越來越高，永磁變頻空壓機因為(wei)它較(jiao)(jiao)高的(de)技術含量，目前在市(shi)場上還是比較(jiao)(jiao)受人(ren)歡(huan)迎的(de)，那么(me)永磁變(bian)頻(pin)(pin)空壓(ya)機(ji)為(wei)什(shen)么(me)會這么(me)受人(ren)歡(huan)迎?永磁變(bian)頻(pin)(pin)空壓(ya)機(ji)與普(pu)通(tong)變(bian)頻(pin)(pin)空壓(ya)機(ji)有(you)什(shen)么(me)區別(bie)?下面(mian)一起聽一聽東莞(guan)美博小編(bian)的(de)分享吧!
永磁變(bian)頻(pin)空壓機與普(pu)通(tong)變(bian)頻(pin)空壓機有什么區別?
區別一、效率高
這里所說的(de)(de)效率高(gao)，不僅指額定功率點(dian)的(de)(de)效率與普通三相異步電(dian)機相分離，還(huan)指其(qi)在整個調速(su)范圍內(nei)的(de)(de)平均效率。永磁(ci)變頻空壓機的(de)(de)勵磁(ci)磁(ci)場由永磁(ci)體提(ti)供，轉子不需要(yao)勵磁(ci)電(dian)流，提(ti)高(gao)了電(dian)機效率。與異步電(dian)機相比，它可以在任(ren)何速(su)度點(dian)節省電(dian)能，尤其(qi)是在低(di)速(su)時(shi)。
區別(bie)二、啟動轉矩
一(yi)般來說(shuo)，永磁變頻空壓機也采(cai)用(yong)異步起動(dong)(dong)方(fang)式。由(you)于它正常(chang)工作(zuo)時(shi)轉(zhuan)子(zi)繞(rao)組(zu)承受(shou)不起作(zuo)用(yong)，所以在設計它時(shi)，轉(zhuan)子(zi)繞(rao)組(zu)完全(quan)可以滿足高(gao)起動(dong)(dong)轉(zhuan)矩(ju)的(de)要求，例如(ru)起動(dong)(dong)時(shi)間從1.8倍增加到2.5倍，甚至(zhi)更大(da)。
區(qu)別三、對電網運行的(de)影(ying)響(xiang)
由(you)于異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)低功(gong)率(lv)(lv)(lv)因(yin)數(shu)(shu)，電(dian)(dian)(dian)(dian)(dian)(dian)機不得不從(cong)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)中吸收大(da)量(liang)(liang)的(de)(de)無(wu)功(gong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)和(he)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)中產生大(da)量(liang)(liang)的(de)(de)無(wu)功(gong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，這(zhe)進(jin)一(yi)步(bu)降(jiang)低了(le)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)的(de)(de)品質(zhi)因(yin)數(shu)(shu)，增加了(le)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)、炮變電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)和(he)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)的(de)(de)負荷。同(tong)時(shi)，無(wu)功(gong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)消耗(hao)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)、變電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)和(he)發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)的(de)(de)部分電(dian)(dian)(dian)(dian)(dian)(dian)能，導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)效(xiao)(xiao)率(lv)(lv)(lv)低下，影響電(dian)(dian)(dian)(dian)(dian)(dian)能的(de)(de)有(you)效(xiao)(xiao)利用。同(tong)樣，由(you)于異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)低效(xiao)(xiao)率(lv)(lv)(lv)，需(xu)(xu)要(yao)從(cong)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)中吸收更多的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)能以滿足發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)需(xu)(xu)求，這(zhe)進(jin)一(yi)步(bu)增加了(le)電(dian)(dian)(dian)(dian)(dian)(dian)能的(de)(de)損失并加重(zhong)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)的(de)(de)負荷。永磁(ci)變頻空壓機轉子無(wu)感(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)勵磁(ci)，電(dian)(dian)(dian)(dian)(dian)(dian)機功(gong)率(lv)(lv)(lv)因(yin)數(shu)(shu)高(gao)，提高(gao)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)品質(zhi)因(yin)數(shu)(shu)，無(wu)需(xu)(xu)在電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)中安裝補償器。同(tong)時(shi)，由(you)于它的(de)(de)效(xiao)(xiao)率(lv)(lv)(lv)高(gao)，電(dian)(dian)(dian)(dian)(dian)(dian)能也得以節省(sheng)。
區別四、體積小，重量輕
由(you)于采用高性能永磁(ci)(ci)材料(liao)提供磁(ci)(ci)場，永磁(ci)(ci)變(bian)頻空壓機(ji)的(de)氣隙磁(ci)(ci)場比(bi)感(gan)應(ying)電(dian)機(ji)大(da)(da)，它(ta)的(de)體積和重量比(bi)感(gan)應(ying)電(dian)機(ji)可以(yi)大(da)(da)大(da)(da)減少(shao)，比(bi)如11kW異步(bu)電(dian)機(ji)的(de)重量為(wei)220kg，而它(ta)只有92kg，相當于異步(bu)電(dian)機(ji)重量的(de)45.8%。
