新政鎮機械密封利用機(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中應(ying)用非常廣泛，有多種形式(shi)，主要(yao)(yao)包括(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大(da)功率的(de)(de)(de)(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準(zhun)(zhun)確(que)，但一般(ban)要(yao)(yao)求較高的(de)(de)(de)(de)(de)制(zhi)造精度和安裝精度。還有一類是靠機(ji)件(jian)間(jian)的(de)(de)(de)(de)(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和摩(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無(wu)級(ji)變速，可(ke)以適應(ying)軸(zhou)間(jian)距較大(da)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而過載打滑(hua)還能(neng)起到緩沖和保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)(de)(de)作用，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般(ban)不能(neng)用于(yu)大(da)功率的(de)(de)(de)(de)(de)場(chang)合，也不能(neng)保證準(zhun)(zhun)確(que)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是新政鎮機械密封的更換工作大同小異(yi)，首先(xian)拆(chai)前需確認(ren)電機(ji)處于檢修狀態，擰下加油(you)螺塞，用吸(xi)管(guan)把密封(feng)座(zuo)腔內的潤滑(hua)油(you)吸(xi)出。準備好放置(zhi)泵零(ling)(ling)件的工作臺及(ji)拆(chai)裝工具，切勿任(ren)意亂放亂用，避免碰(peng)壞(huai)泵的零(ling)(ling)部件。

　　拆對分式(shi)聯(lian)軸(zhou)器(qi)(qi)(qi)：先把(ba)聯(lian)軸(zhou)器(qi)(qi)(qi)的(de)固定內六角螺釘擰下(xia)來，再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)(qi)(qi)的(de)一半從(cong)軸(zhou)上(shang)慢慢拉下(xia)，注意不要掉(diao)了，再用(yong)梅花扳手(shou)擰下(xia)泵軸(zhou)吊緊螺栓(shuan)和擋塊，讓葉(xie)輪慢慢下(xia)沉至泵體(ti)，然后拆下(xia)另外一半聯(lian)軸(zhou)器(qi)(qi)(qi)，拿(na)下(xia)泵軸(zhou)擋圈。

　　拆卸新政鎮機械密封：抓住密(mi)封彈簧順著(zhu)泵(beng)軸(zhou)往上提，就(jiu)能拆(chai)下來(lai)了。

　　拆卸(xie)并(bing)清洗軸(zhou)承座：先輕(qing)輕(qing)松動一下軸(zhou)承座后用拆卸(xie)螺栓頂起軸(zhou)承座，并(bing)且沿(yan)著泵軸(zhou)往上(shang)提而卸(xie)下，再用噴氣燃料(liao)清洗軸(zhou)承及座，裝前晾干并(bing)涂抹(mo)少許20號機械油用來(lai)潤滑保護。

　　拆密(mi)封座(zuo)：擰(ning)下密(mi)封座(zuo)壓緊螺(luo)母，輕(qing)輕(qing)卸下密(mi)封座(zuo)并清洗。

　　新政鎮機械密封裝配：在(zai)動、靜(jing)環鏡面(mian)上(shang)涂(tu)一層(ceng)潔凈(jing)的20號潤(run)滑(hua)油(you)，導軸承(cheng)座也抹(mo)上(shang)潤(run)滑(hua)油(you)，先(xian)把(ba)靜(jing)環輕(qing)(qing)輕(qing)(qing)定位(wei)裝入導軸承(cheng)座，再在(zai)泵軸上(shang)抹(mo)上(shang)潤(run)滑(hua)油(you)，把(ba)動環部(bu)分輕(qing)(qing)輕(qing)(qing)裝入泵軸上(shang)，用手輕(qing)(qing)推密封(feng)環應能伸縮自如，注意動、靜(jing)環部(bu)分的防(fang)轉(zhuan)部(bu)位(wei)需裝配到位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈(quan)，裝(zhuang)上(shang)(shang)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器，再(zai)在泵軸(zhou)(zhou)(zhou)端和(he)聯(lian)軸(zhou)(zhou)(zhou)器槽(cao)內(nei)裝(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳(ban)手擰緊螺栓；再(zai)裝(zhuang)上(shang)(shang)另一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器擰上(shang)(shang)內(nei)六角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器正確的檢查要(yao)求：對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器上(shang)(shang)下間隙需要(yao)均勻，用手盤動(dong)聯(lian)軸(zhou)(zhou)(zhou)器幾圈(quan)檢查轉動(dong)的靈(ling)活性。

　　裝(zhuang)(zhuang)密封(feng)座(zuo)(zuo)：先將密封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)入橡膠油封(feng)，再把密封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)入泵蓋(gai)(gai)并壓在(zai)軸承座(zuo)(zuo)上(shang)，擰緊螺母，確保所有安(an)裝(zhuang)(zhuang)螺釘緊固(gu)(gu)。當安(an)裝(zhuang)(zhuang)螺釘被用作密封(feng)與軸之間的(de)驅(qu)動時，軸應打(da)埋頭孔來加固(gu)(gu)連接，緊固(gu)(gu)壓蓋(gai)(gai)螺栓(shuan)時應該平穩緊固(gu)(gu)，并且(qie)不要使壓蓋(gai)(gai)受彈力。在(zai)可(ke)能的(de)地方使用4個以上(shang)螺釘的(de)等間距壓蓋(gai)(gai)，緊固(gu)(gu)壓蓋(gai)(gai)螺栓(shuan)時，用塞(sai)尺檢查軸與壓蓋(gai)(gai)之間的(de)間隙(xi)，這在(zai)密封(feng)腔對壓蓋(gai)(gai)不導向(xiang)時，顯得(de)特別重要，因為壓蓋(gai)(gai)必須對中。
