如何保持錘式破碎機的轉子平衡?
錘式破碎機轉子的平衡是錘式破碎機在生產中常見并且需要改進的問題之一。錘(chui)式破碎機轉(zhuan)子質量(liang)大(da),圓周速度高,如果轉(zhuan)子中心(xin)偏離旋轉(zhuan)中心(xin)較大(da),將(jiang)產生巨大(da)的離心(xin)力而使機器強(qiang)烈(lie)震動,使軸承(cheng)過早(zao)磨損(sun)(sun),軸彎曲或局部磨損(sun)(sun)嚴重。因此,在檢修和更換(huan)錘(chui)頭時,要(yao)求轉(zhuan)子保持比較精確(que)的平衡(heng)。
錘(chui)(chui)(chui)(chui)(chui)式(shi)破(po)碎(sui)機(ji)轉子主要找(zhao)(zhao)(zhao)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),其操作方法是:首先找(zhao)(zhao)(zhao)破(po)碎(sui)機(ji)主軸(zhou)與錘(chui)(chui)(chui)(chui)(chui)架(jia)的(de)(de)(de)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),將(jiang)主軸(zhou)裝(zhuang)上一片(pian)(pian)錘(chui)(chui)(chui)(chui)(chui)架(jia),在(zai)(zai)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)架(jia)上找(zhao)(zhao)(zhao)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),在(zai)(zai)不平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)質量(liang)的(de)(de)(de)相反方向架(jia)上配重(zhong)(zhong)(zhong)(zhong),使其達到(dao)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),然后再裝(zhuang)一片(pian)(pian)錘(chui)(chui)(chui)(chui)(chui)架(jia),找(zhao)(zhao)(zhao)其靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),并配重(zhong)(zhong)(zhong)(zhong)在(zai)(zai)第二片(pian)(pian)錘(chui)(chui)(chui)(chui)(chui)架(jia)上。依(yi)次找(zhao)(zhao)(zhao)裝(zhuang)上每(mei)片(pian)(pian)錘(chui)(chui)(chui)(chui)(chui)架(jia)后靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),將(jiang)每(mei)塊配重(zhong)(zhong)(zhong)(zhong)稱好,以(yi)等重(zhong)(zhong)(zhong)(zhong)鐵板(ban)分(fen)別焊(han)在(zai)(zai)每(mei)片(pian)(pian)錘(chui)(chui)(chui)(chui)(chui)架(jia)的(de)(de)(de)配重(zhong)(zhong)(zhong)(zhong)位(wei)置上,注(zhu)意焊(han)后不要影(ying)響錘(chui)(chui)(chui)(chui)(chui)頭(tou)工作。主軸(zhou)與追加的(de)(de)(de)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)找(zhao)(zhao)(zhao)好后,安裝(zhuang)在(zai)(zai)錘(chui)(chui)(chui)(chui)(chui)頭(tou)時,需(xu)將(jiang)錘(chui)(chui)(chui)(chui)(chui)頭(tou)的(de)(de)(de)重(zhong)(zhong)(zhong)(zhong)量(liang)搭配好,使錘(chui)(chui)(chui)(chui)(chui)頭(tou)的(de)(de)(de)重(zhong)(zhong)(zhong)(zhong)量(liang)排列(lie)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),可將(jiang)鄂頭(tou)分(fen)為特(te)重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de),很重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de),較(jiao)重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)和輕的(de)(de)(de)四種排列(lie)方式(shi)。也可將(jiang)錘(chui)(chui)(chui)(chui)(chui)頭(tou)分(fen)為重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de),較(jiao)重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)和輕的(de)(de)(de)三種。 總之更換錘(chui)(chui)(chui)(chui)(chui)頭(tou)時,要使破(po)碎(sui)機(ji)轉子圓(yuan)周防線(xian)每(mei)排錘(chui)(chui)(chui)(chui)(chui)頭(tou)的(de)(de)(de)重(zhong)(zhong)(zhong)(zhong)量(liang)相等,軸(zhou)向重(zhong)(zhong)(zhong)(zhong)量(liang)排列(lie)均勻,這樣破(po)碎(sui)機(ji)運轉時轉子才能達到(dao)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng),避免振動。
礦山設備行業的人都知道,錘式破碎機錘頭的磨損問題是(shi)與很多因(yin)素相(xiang)關的(de)(de),比如物料的(de)(de)粒度(du)大(da)小、種類、硬度(du)、水分、溫度(du)等物料性(xing)質,錘頭(tou)的(de)(de)線速(su)度(du),排料口的(de)(de)設(she)等都會導(dao)致錘頭(tou)磨損的(de)(de)不同差(cha)異,因(yin)此,對(dui)生產廠家來說(shuo),合理選材(cai)十(shi)分重要、經過長期的(de)(de)跟蹤實(shi)踐(jian),鄭州(zhou)紅星礦山設(she)備有限公司(si)的(de)(de)工程師(shi)們發現錘頭(tou)的(de)(de)磨損和材(cai)料的(de)(de)選擇是(shi)與破碎(sui)機(ji)的(de)(de)型(xing)號大(da)小有關的(de)(de)。
