雙塔機械密封利(li)用(yong)機械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機械工程中應用(yong)非(fei)常廣泛，有多(duo)種(zhong)形(xing)式，主(zhu)要包(bao)括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于大功率的場(chang)(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確，但一般要求較高的制(zhi)造精度和(he)(he)安裝(zhuang)精度。還有一類(lei)是靠(kao)機件間的摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易(yi)實現無級變速，可以(yi)適應軸(zhou)間距較大的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合，而過載打滑還能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的作(zuo)用(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不(bu)能(neng)用(yong)于大功率的場(chang)(chang)合，也不(bu)能(neng)保證準確的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是雙塔機械密封的(de)(de)更換工作(zuo)大(da)同小異，首先拆(chai)前需確認電機處于檢(jian)修狀態，擰下加油螺塞(sai)，用(yong)吸(xi)管把密封座腔內的(de)(de)潤滑油吸(xi)出。準備(bei)好放置泵零件(jian)的(de)(de)工作(zuo)臺及(ji)拆(chai)裝(zhuang)工具，切勿任(ren)意(yi)亂放亂用(yong)，避免碰壞(huai)泵的(de)(de)零部件(jian)。

　　拆對(dui)分式(shi)聯(lian)軸(zhou)器(qi)：先把聯(lian)軸(zhou)器(qi)的固定內六角(jiao)螺釘(ding)擰下(xia)(xia)(xia)來(lai)，再輕(qing)(qing)輕(qing)(qing)把聯(lian)軸(zhou)器(qi)的一半(ban)(ban)從(cong)軸(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia)，注意(yi)不要掉(diao)了，再用梅花(hua)扳手(shou)擰下(xia)(xia)(xia)泵軸(zhou)吊緊螺栓和(he)擋(dang)塊(kuai)，讓葉(xie)輪慢(man)慢(man)下(xia)(xia)(xia)沉至泵體，然(ran)后拆下(xia)(xia)(xia)另外一半(ban)(ban)聯(lian)軸(zhou)器(qi)，拿下(xia)(xia)(xia)泵軸(zhou)擋(dang)圈(quan)。

　　拆卸雙塔機械密封：抓(zhua)住密封彈簧(huang)順著泵軸往(wang)上提(ti)，就能拆下(xia)來了。

　　拆卸并(bing)(bing)清洗軸(zhou)承座(zuo)：先輕輕松動一下軸(zhou)承座(zuo)后用拆卸螺栓頂起軸(zhou)承座(zuo)，并(bing)(bing)且沿著泵軸(zhou)往上提(ti)而卸下，再用噴氣燃料清洗軸(zhou)承及座(zuo)，裝前(qian)晾干并(bing)(bing)涂抹少許20號機械油用來潤(run)滑保(bao)護。

　　拆密(mi)封(feng)(feng)座：擰下密(mi)封(feng)(feng)座壓緊螺(luo)母(mu)，輕輕卸下密(mi)封(feng)(feng)座并(bing)清(qing)洗。

　　雙塔機械密封裝(zhuang)(zhuang)(zhuang)配：在(zai)動、靜環鏡(jing)面上(shang)涂一(yi)層潔凈的20號潤(run)(run)滑(hua)油，導軸承座也抹上(shang)潤(run)(run)滑(hua)油，先把(ba)靜環輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)(zhuang)(zhuang)入導軸承座，再在(zai)泵(beng)軸上(shang)抹上(shang)潤(run)(run)滑(hua)油，把(ba)動環部分輕(qing)(qing)輕(qing)(qing)裝(zhuang)(zhuang)(zhuang)入泵(beng)軸上(shang)，用手輕(qing)(qing)推密(mi)封環應能伸縮自如，注意動、靜環部分的防轉(zhuan)部位需裝(zhuang)(zhuang)(zhuang)配到位。

　　裝(zhuang)(zhuang)聯軸(zhou)器：在電機軸(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)上(shang)擋圈，裝(zhuang)(zhuang)上(shang)一半聯軸(zhou)器，再(zai)在泵軸(zhou)端(duan)和聯軸(zhou)器槽內裝(zhuang)(zhuang)上(shang)擋塊并用梅花扳手(shou)擰(ning)緊(jin)螺(luo)栓；再(zai)裝(zhuang)(zhuang)上(shang)另一半聯軸(zhou)器擰(ning)上(shang)內六角螺(luo)釘。安裝(zhuang)(zhuang)聯軸(zhou)器正確的檢查(cha)要求(qiu)：對分式聯軸(zhou)器上(shang)下間隙需要均勻(yun)，用手(shou)盤動聯軸(zhou)器幾圈檢查(cha)轉動的靈活(huo)性(xing)。

　　裝(zhuang)密(mi)封座：先(xian)將密(mi)封座裝(zhuang)入(ru)橡膠油封，再把密(mi)封座裝(zhuang)入(ru)泵蓋(gai)并壓(ya)(ya)在軸承(cheng)座上(shang)，擰(ning)緊(jin)(jin)螺(luo)母，確保所有安裝(zhuang)螺(luo)釘緊(jin)(jin)固(gu)(gu)。當安裝(zhuang)螺(luo)釘被用作密(mi)封與(yu)軸之間(jian)(jian)的(de)驅(qu)動時，軸應打埋頭孔來(lai)加固(gu)(gu)連(lian)接，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時應該平穩緊(jin)(jin)固(gu)(gu)，并且不要使(shi)(shi)壓(ya)(ya)蓋(gai)受彈力(li)。在可能(neng)的(de)地方使(shi)(shi)用4個以上(shang)螺(luo)釘的(de)等間(jian)(jian)距壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時，用塞尺檢(jian)查軸與(yu)壓(ya)(ya)蓋(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這(zhe)在密(mi)封腔(qiang)對壓(ya)(ya)蓋(gai)不導向時，顯得特(te)別重要，因為壓(ya)(ya)蓋(gai)必(bi)須對中(zhong)。
