鄂式(shi)破(po)碎(sui)機(ji)在(zai)日(ri)常使用(yong)中，出現磨(mo)(mo)(mo)損(sun)是(shi)不可(ke)避免(mian)的(de)，如何降低磨(mo)(mo)(mo)損(sun)，不僅(jin)能提高(gao)生(sheng)產效率，還有(you)提高(gao)經濟效益，所以我們在(zai)鄂式(shi)破(po)碎(sui)機(ji)的(de)心(xin)(xin)軸(zhou)，偏心(xin)(xin)軸(zhou)和軸(zhou)瓦(wa)(wa)方面進行長期(qi)(qi)的(de)保養(yang)。顎(e)式(shi)破(po)碎(sui)機(ji)工(gong)作方式(shi)為(wei)曲(qu)動(dong)(dong)(dong)(dong)(dong)擠壓(ya)型，其工(gong)作原理(li)是(shi)：電動(dong)(dong)(dong)(dong)(dong)機(ji)驅動(dong)(dong)(dong)(dong)(dong)皮帶和皮帶輪，通(tong)過偏心(xin)(xin)軸(zhou)使動(dong)(dong)(dong)(dong)(dong)顎(e)上(shang)下運動(dong)(dong)(dong)(dong)(dong)，當動(dong)(dong)(dong)(dong)(dong)顎(e)上(shang)升時(shi)(shi)(shi)肘板(ban)與動(dong)(dong)(dong)(dong)(dong)顎(e)間夾角變(bian)大，從而(er)推動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)顎(e)板(ban)向(xiang)固定(ding)顎(e)板(ban)接近(jin)，與其同(tong)時(shi)(shi)(shi)物(wu)料(liao)(liao)被壓(ya)碎(sui)或劈碎(sui)，達到破(po)碎(sui) 的(de)目的(de)；當動(dong)(dong)(dong)(dong)(dong)顎(e)下行時(shi)(shi)(shi)，肘板(ban)與動(dong)(dong)(dong)(dong)(dong)顎(e)夾角變(bian)小，動(dong)(dong)(dong)(dong)(dong)顎(e)板(ban)在(zai)拉桿，彈簧的(de)作用(yong)下，離開(kai)固定(ding)顎(e)板(ban)，此時(shi)(shi)(shi)已破(po)碎(sui)物(wu)料(liao)(liao) 從破(po)碎(sui)腔下口(kou)排出。隨(sui)著(zhu)電動(dong)(dong)(dong)(dong)(dong)機(ji)連(lian)續轉動(dong)(dong)(dong)(dong)(dong)而(er)破(po)碎(sui)機(ji)動(dong)(dong)(dong)(dong)(dong)顎(e)作周期(qi)(qi)運動(dong)(dong)(dong)(dong)(dong)壓(ya)碎(sui)和排泄物(wu)料(liao)(liao)，實現批量(liang)生(sheng)產。首先，軸(zhou)的(de)磨(mo)(mo)(mo)損(sun)如果很少，僅(jin)僅(jin)為(wei)了(le)修(xiu)復它的(de)幾何形(xing)狀，可(ke)在(zai)車床上(shang)車削，使軸(zhou)頸(jing)達到正(zheng)確(que)的(de)幾何形(xing)狀，然(ran)后相應(ying)的(de)減小軸(zhou)承內(nei)徑。但經過幾次這樣處理(li)后，如果軸(zhou)頸(jing)尺寸較(jiao)原來減小5%時(shi)(shi)(shi)，就不允許再車削了(le)，而(er)應(ying)該更換(huan) 新(xin)(xin)軸(zhou)。再次，顎(e)式(shi)破(po)碎(sui)機(ji)是(shi)在(zai)沖(chong)擊(ji)負(fu)荷(he)下工(gong)作的(de)，軸(zhou)瓦(wa)(wa)上(shang)的(de)巴(ba)氏合(he)(he)金襯，工(gong)作期(qi)(qi)限大約(yue)二年左右，超(chao)過期(qi)(qi)限，則(ze)需要重新(xin)(xin)澆(jiao)(jiao)鑄。如果偏心(xin)(xin)軸(zhou)與軸(zhou)瓦(wa)(wa)、心(xin)(xin)軸(zhou)與軸(zhou)瓦(wa)(wa)被磨(mo)(mo)(mo)損(sun)，其頂(ding)間隙(xi)大于(yu)原裝配(pei)間隙(xi)的(de)1.5倍時(shi)(shi)(shi)，需加(jia)墊調整或更換(huan)；油溝(gou)磨(mo)(mo)(mo)損(sun)1.5毫米，則(ze)應(ying)重開(kai)油溝(gou)和調整。連(lian)桿頭上(shang)蓋與偏心(xin)(xin)軸(zhou)之間的(de)間隙(xi)，磨(mo)(mo)(mo)損(sun)到大于(yu)裝配(pei)間隙(xi)的(de)1.5倍時(shi)(shi)(shi)，也需要加(jia)墊調整或更換(huan)新(xin)(xin)的(de)。當軸(zhou)瓦(wa)(wa)上(shang)的(de)巴(ba)氏合(he)(he)金有(you)較(jiao)深剝開(kai)或較(jiao)大的(de)擦傷時(shi)(shi)(shi)，應(ying)重新(xin)(xin)澆(jiao)(jiao)鑄。對于(yu)加(jia)工(gong)后的(de)軸(zhou)瓦(wa)(wa)質(zhi)量(liang)有(you) 如下要求：巴(ba)氏合(he)(he)金表(biao)面的(de)顏色要均(jun)勻、無光、銀白色；巴(ba)氏合(he)(he)金表(biao)面層(ceng)不應(ying)有(you)灰渣(zha)、裂紋、砂眼、縮孔(kong)等(deng)及(ji)剝殼現象。
