1、傳動(dong)(dong)(dong)軸(zhou)和襯(chen)(chen)(chen)套(tao)磨損(sun)(sun)后的(de)(de)修理(li):高溫導熱(re)油(you)泵的(de)(de)傳動(dong)(dong)(dong)軸(zhou)和襯(chen)(chen)(chen)套(tao)磨損(sun)(sun)后,匹配間(jian)隙會(hui)增加,這(zhe)(zhe)肯定(ding)會(hui)影響泵油(you)量。在這(zhe)(zhe)種情況下,可以(yi)通過修理(li)驅(qu)動(dong)(dong)(dong)軸(zhou)或襯(chen)(chen)(chen)套(tao)來恢(hui)復正常的(de)(de)配合間(jian)隙。如(ru)果驅(qu)動(dong)(dong)(dong)軸(zhou)磨損(sun)(sun)很小,只需推出舊的(de)(de)襯(chen)(chen)(chen)套(tao)并用標準(zhun)尺寸的(de)(de)襯(chen)(chen)(chen)套(tao)替換(huan)(huan)它,就可以(yi)將配合間(jian)隙恢(hui)復到允許的(de)(de)范圍(wei)。如(ru)果驅(qu)動(dong)(dong)(dong)軸(zhou)和襯(chen)(chen)(chen)套(tao)嚴重(zhong)磨損(sun)(sun),并且嚴重(zhong)超出裝(zhuang)配間(jian)隙,則不僅需要(yao)更換(huan)(huan)襯(chen)(chen)(chen)套(tao),還應對熱(re)水泵和驅(qu)動(dong)(dong)(dong)軸(zhou)進行(xing)鍍(du)鉻(ge)或振動(dong)(dong)(dong)處(chu)理(li)以(yi)增大(da)其直(zhi)徑,然(ran)后磨成標準(zhun)尺寸。襯(chen)(chen)(chen)套(tao)的(de)(de)匹配要(yao)求。
2、修復主(zhu)(zhu)動(dong)軸(zhou)(zhou)襯(chen)套(tao)(tao)孔(kong)(kong)(kong)(kong)(kong)和從(cong)(cong)動(dong)軸(zhou)(zhou)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)磨(mo)(mo)(mo)損(sun):主(zhu)(zhu)動(dong)軸(zhou)(zhou)襯(chen)套(tao)(tao)孔(kong)(kong)(kong)(kong)(kong)磨(mo)(mo)(mo)損(sun)后(hou),熱水(shui)泵可(ke)采用(yong)擴(kuo)孔(kong)(kong)(kong)(kong)(kong)方(fang)(fang)法(fa)消除磨(mo)(mo)(mo)損(sun)痕跡,然后(hou)使用(yong)擴(kuo)大的(de)(de)襯(chen)套(tao)(tao)相應的(de)(de)大小。從(cong)(cong)動(dong)軸(zhou)(zhou)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)磨(mo)(mo)(mo)損(sun)也(ye)可(ke)以通過鉸孔(kong)(kong)(kong)(kong)(kong)方(fang)(fang)法(fa)消除,然后(hou)根據鉸孔(kong)(kong)(kong)(kong)(kong)后(hou)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)實際尺(chi)寸準備從(cong)(cong)動(dong)軸(zhou)(zhou)。
3、修理泵(beng)(beng)(beng)蓋(gai)工(gong)作平(ping)面(mian):如(ru)果泵(beng)(beng)(beng)蓋(gai)工(gong)作表面(mian)的(de)磨損(sun)較少,則可(ke)以手動研磨熱(re)水泵(beng)(beng)(beng)以消(xiao)除(chu)磨損(sun)跡象(xiang),即(ji)在平(ping)臺或厚玻璃(li)板上放一點閥(fa)砂,然(ran)后將泵(beng)(beng)(beng)蓋(gai)放到地面(mian),直到磨損(sun)痕跡消(xiao)失并(bing)且工(gong)作表面(mian)平(ping)坦(tan)。當泵(beng)(beng)(beng)蓋(gai)工(gong)作表面(mian)的(de)工(gong)作深度超過(guo)0.1毫米時(shi),應首先轉動并(bing)打磨修復。
另外,拆卸(xie)導(dao)熱油(you)泵時要注意的事(shi)項:
1、拆卸熱油泵的(de)機械密(mi)封件時,嚴禁使用(yong)手錘和刮鏟,以免損壞密(mi)封件。
2、對(dui)于已起(qi)作(zuo)用的機(ji)械密(mi)(mi)封(feng),如果(guo)在壓(ya)蓋松(song)動時密(mi)(mi)封(feng)表(biao)面(mian)移動,則應更換動環和(he)靜(jing)環部件。導熱(re)油泵不應擰(ning)緊(jin)并繼續使用。因為在松(song)動之后,摩擦副的原始(shi)運行軌跡將發生變化,并且接觸面(mian)的密(mi)(mi)封(feng)將很(hen)容易損(sun)壞。
3、如(ru)果密封元件被灰塵或冷凝水(shui)粘(zhan)附,請在拆卸機械密封之前(qian)先除去冷凝水(shui)。
組裝好泵頭后,將其浸入水中以檢查氣壓。如果導熱油泵有泄漏,則說明組裝過程中有泄漏。必須調整后泵頭和電動機的同心度,否則噪音會很大并且聯軸器軸內的橡膠塊磨損得太快。
