傳動形式多,但是普陀機械密封的更換工作大同小異,首先拆前需確認(ren)電機(ji)處于檢修狀態,擰下加油螺(luo)塞,用吸管(guan)把密封座(zuo)腔內的潤滑(hua)油吸出。準備好放置(zhi)泵(beng)零(ling)(ling)件的工作臺及(ji)拆裝工具,切勿任意亂(luan)放亂(luan)用,避免碰壞泵(beng)的零(ling)(ling)部(bu)件。
拆對分式聯(lian)軸(zhou)(zhou)器:先把聯(lian)軸(zhou)(zhou)器的固(gu)定內六角螺(luo)釘擰下(xia)(xia)(xia)來(lai),再輕(qing)輕(qing)把聯(lian)軸(zhou)(zhou)器的一半從軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia),注意(yi)不(bu)要(yao)掉了(le),再用梅(mei)花扳手擰下(xia)(xia)(xia)泵(beng)(beng)軸(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊,讓葉(xie)輪(lun)慢(man)慢(man)下(xia)(xia)(xia)沉至泵(beng)(beng)體,然后拆下(xia)(xia)(xia)另外(wai)一半聯(lian)軸(zhou)(zhou)器,拿下(xia)(xia)(xia)泵(beng)(beng)軸(zhou)(zhou)擋(dang)圈。
拆卸普陀機械密封:抓住密封彈簧順(shun)著泵軸往上(shang)提,就能拆下來(lai)了。
拆(chai)卸(xie)(xie)并清洗(xi)(xi)軸承(cheng)座:先輕(qing)輕(qing)松動一下軸承(cheng)座后(hou)用拆(chai)卸(xie)(xie)螺栓頂起軸承(cheng)座,并且(qie)沿著泵(beng)軸往上提(ti)而卸(xie)(xie)下,再用噴氣燃料清洗(xi)(xi)軸承(cheng)及(ji)座,裝(zhuang)前晾干并涂抹少(shao)許20號機械油用來潤滑保(bao)護。
拆(chai)密封(feng)座:擰下(xia)密封(feng)座壓緊螺(luo)母,輕輕卸下(xia)密封(feng)座并(bing)清(qing)洗。
普陀機械密封裝(zhuang)配:在動、靜環(huan)鏡面上(shang)(shang)涂(tu)一層潔凈的(de)20號潤滑油,導軸承座也抹上(shang)(shang)潤滑油,先把(ba)靜環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入導軸承座,再在泵軸上(shang)(shang)抹上(shang)(shang)潤滑油,把(ba)動環(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)入泵軸上(shang)(shang),用(yong)手輕(qing)推密封環(huan)應能伸縮(suo)自如(ru),注意(yi)動、靜環(huan)部分(fen)的(de)防轉部位(wei)需裝(zhuang)配到位(wei)。
裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi):在電(dian)機(ji)軸(zhou)(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan),裝(zhuang)(zhuang)上(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi),再在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)擋塊(kuai)并用梅花扳手(shou)擰(ning)緊螺栓;再裝(zhuang)(zhuang)上(shang)另(ling)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)擰(ning)上(shang)內(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)正確的(de)檢(jian)查要(yao)求:對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)上(shang)下間隙需要(yao)均勻,用手(shou)盤動(dong)(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)幾圈(quan)檢(jian)查轉動(dong)(dong)的(de)靈活性。
裝密(mi)(mi)(mi)封座(zuo):先(xian)將密(mi)(mi)(mi)封座(zuo)裝入橡膠油封,再把密(mi)(mi)(mi)封座(zuo)裝入泵蓋(gai)(gai)(gai)并(bing)(bing)壓(ya)在軸(zhou)(zhou)承座(zuo)上,擰緊(jin)螺(luo)母,確保所有安裝螺(luo)釘(ding)緊(jin)固(gu)(gu)。當安裝螺(luo)釘(ding)被用作密(mi)(mi)(mi)封與軸(zhou)(zhou)之(zhi)間(jian)(jian)的(de)驅動時,軸(zhou)(zhou)應(ying)打(da)埋頭(tou)孔來加固(gu)(gu)連接,緊(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)栓時應(ying)該平穩緊(jin)固(gu)(gu),并(bing)(bing)且不要(yao)使壓(ya)蓋(gai)(gai)(gai)受彈力。在可(ke)能的(de)地方使用4個以上螺(luo)釘(ding)的(de)等(deng)間(jian)(jian)距(ju)壓(ya)蓋(gai)(gai)(gai),緊(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)栓時,用塞尺檢查軸(zhou)(zhou)與壓(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙,這在密(mi)(mi)(mi)封腔對(dui)壓(ya)蓋(gai)(gai)(gai)不導向時,顯得特別重要(yao),因為壓(ya)蓋(gai)(gai)(gai)必須(xu)對(dui)中(zhong)。
