動平(ping)衡(heng)機做為(wei)技術性含量(liang)較為(wei)高的(de)精密儀器設備，因為(wei)對(dui)動平(ping)衡(heng)機不(bu)夠(gou)了解，在采購或選用動平(ping)衡(heng)機過程中，難免(mian)會(hui)存(cun)有誤(wu)區。下邊就給大家詳細介紹下有關動平(ping)衡(heng)機的(de)四大誤(wu)區。

01

平(ping)衡轉速和平(ping)衡精密度

因為對動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)不(bu)夠了解，客戶通(tong)常覺得(de)做動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)的(de)(de)(de)(de)(de)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)轉(zhuan)(zhuan)速(su)越(yue)高，平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精(jing)(jing)密(mi)(mi)度(du)越(yue)好(hao)(hao)，其實不(bu)然。一(yi)(yi)臺(tai)好(hao)(hao)的(de)(de)(de)(de)(de)硬支承動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)（剛性擺架的(de)(de)(de)(de)(de)動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)）能在越(yue)低(di)的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)下正確檢(jian)(jian)測(ce)出不(bu)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)量的(de)(de)(de)(de)(de)大(da)小(xiao)，而并(bing)不(bu)是轉(zhuan)(zhuan)速(su)越(yue)高，平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精(jing)(jing)密(mi)(mi)度(du)越(yue)好(hao)(hao)。針對不(bu)一(yi)(yi)樣質(zhi)量和(he)形狀的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)子，我(wo)們會采用不(bu)一(yi)(yi)樣的(de)(de)(de)(de)(de)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)轉(zhuan)(zhuan)速(su)，以達到動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)的(de)(de)(de)(de)(de)較(jiao)高檢(jian)(jian)測(ce)效率和(he)檢(jian)(jian)測(ce)精(jing)(jing)密(mi)(mi)度(du)。通(tong)常情況下，硬支承動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)控制在200-1500r/min范(fan)(fan)圍(wei)(wei)之內，可滿足大(da)部分轉(zhuan)(zhuan)子動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)的(de)(de)(de)(de)(de)標準(zhun)；針對軟支承動(dong)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)機(ji)而言，平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)轉(zhuan)(zhuan)速(su)和(he)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精(jing)(jing)密(mi)(mi)度(du)會有一(yi)(yi)定關聯，在一(yi)(yi)定的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)范(fan)(fan)圍(wei)(wei)之內，平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)轉(zhuan)(zhuan)速(su)和(he)平(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精(jing)(jing)密(mi)(mi)度(du)成線性關系。

轉(zhuan)子質量和動平衡機較(jiao)大承載(zai)質量

在(zai)動(dong)(dong)平(ping)(ping)衡(heng)(heng)機(ji)選型(xing)過程中，轉(zhuan)子(zi)質(zhi)(zhi)(zhi)(zhi)量(liang)和(he)(he)動(dong)(dong)平(ping)(ping)衡(heng)(heng)機(ji)較(jiao)大承載(zai)質(zhi)(zhi)(zhi)(zhi)量(liang)是重要參考指標。不(bu)一(yi)樣質(zhi)(zhi)(zhi)(zhi)量(liang)的(de)轉(zhuan)子(zi)會采用不(bu)一(yi)樣型(xing)號(hao)規格的(de)動(dong)(dong)平(ping)(ping)衡(heng)(heng)機(ji)。轉(zhuan)子(zi)質(zhi)(zhi)(zhi)(zhi)量(liang)通常保持在(zai)動(dong)(dong)平(ping)(ping)衡(heng)(heng)機(ji)較(jiao)大承載(zai)質(zhi)(zhi)(zhi)(zhi)量(liang)的(de)百分之二十(shi)五至百分之八十(shi)，動(dong)(dong)平(ping)(ping)衡(heng)(heng)機(ji)的(de)平(ping)(ping)衡(heng)(heng)精密度(du)和(he)(he)平(ping)(ping)衡(heng)(heng)效率較(jiao)好，使用壽命較(jiao)長。

03

轉子平衡(heng)狀態(tai)和工作狀態(tai)

有的(de)(de)(de)(de)客(ke)戶覺得轉(zhuan)子(zi)(zi)動平(ping)衡(heng)(heng)時的(de)(de)(de)(de)支承(cheng)方法要(yao)和(he)工作時的(de)(de)(de)(de)支承(cheng)方法相(xiang)同，轉(zhuan)子(zi)(zi)的(de)(de)(de)(de)動平(ping)衡(heng)(heng)精密度(du)才能夠符(fu)合工作標準(zhun)，這主(zhu)要(yao)是因(yin)為(wei)對動平(ping)衡(heng)(heng)機(ji)不夠了解造成的(de)(de)(de)(de)。動平(ping)衡(heng)(heng)機(ji)是對轉(zhuan)子(zi)(zi)單位質(zhi)量內不平(ping)衡(heng)(heng)量的(de)(de)(de)(de)測量和(he)校正，確保轉(zhuan)子(zi)(zi)在(zai)目前的(de)(de)(de)(de)動平(ping)衡(heng)(heng)機(ji)技術標準(zhun)下，達到該轉(zhuan)子(zi)(zi)質(zhi)量范(fan)圍內不平(ping)衡(heng)(heng)量的(de)(de)(de)(de)較小值。轉(zhuan)子(zi)(zi)動平(ping)衡(heng)(heng)是對轉(zhuan)子(zi)(zi)自身(shen)單位質(zhi)量范(fan)圍的(de)(de)(de)(de)調整，它的(de)(de)(de)(de)精密度(du)和(he)平(ping)衡(heng)(heng)狀態時沒有關聯的(de)(de)(de)(de)，客(ke)戶只需正確安裝(zhuang)轉(zhuan)子(zi)(zi)，就可放心(xin)使用設備。

工作轉速和平衡轉速

經過對客戶(hu)(hu)看法、建議(yi)的(de)(de)采集和(he)整理，有些客戶(hu)(hu)覺得平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)要達到(dao)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)工作轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)動(dong)(dong)平(ping)(ping)衡(heng)(heng)(heng)精密度(du)才會符(fu)合(he)要求，這主要是因為客戶(hu)(hu)對平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)的(de)(de)概念(nian)了(le)解不(bu)清楚造成的(de)(de)。平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)：動(dong)(dong)平(ping)(ping)衡(heng)(heng)(heng)機在(zai)(zai)做動(dong)(dong)平(ping)(ping)衡(heng)(heng)(heng)校驗時(shi)的(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)，針(zhen)對剛性轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)在(zai)(zai)確(que)保精密度(du)的(de)(de)前提條件下(xia)，盡可能挑選(xuan)較低轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)，即(ji)動(dong)(dong)平(ping)(ping)衡(heng)(heng)(heng)機在(zai)(zai)標(biao)定的(de)(de)平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)下(xia)，能以較高效率(lv)測到(dao)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)不(bu)平(ping)(ping)衡(heng)(heng)(heng)量(liang)。平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)的(de)(de)大小關鍵和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)質量(liang)，形狀等有關聯，通(tong)常情況下(xia)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)質量(liang)越大，平(ping)(ping)衡(heng)(heng)(heng)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)越低，和(he)工作轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)沒有關系(xi)。
