隴縣機械密封利用(yong)機(ji)(ji)械(xie)(xie)方(fang)式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)(xie)工程(cheng)中應用(yong)非常廣泛，有多種(zhong)形式，主要(yao)(yao)包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)于大(da)功(gong)率(lv)的(de)場合(he)(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一般要(yao)(yao)求較高的(de)制(zhi)造精(jing)度和(he)(he)安裝精(jing)度。還有一類是靠(kao)機(ji)(ji)件間的(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速(su)，可(ke)以適(shi)應軸(zhou)間距較大(da)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場合(he)(he)，而過載(zai)打滑還能(neng)(neng)起到緩沖和(he)(he)保(bao)護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong)，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)(neng)用(yong)于大(da)功(gong)率(lv)的(de)場合(he)(he)，也不能(neng)(neng)保(bao)證(zheng)準確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是隴縣機械密封的(de)(de)更換工(gong)作大同(tong)小異，首(shou)先拆(chai)前需確認電機(ji)處(chu)于(yu)檢(jian)修狀態，擰下加油(you)螺(luo)塞，用吸(xi)管把(ba)密(mi)封(feng)座腔內的(de)(de)潤(run)滑油(you)吸(xi)出。準備好放(fang)置泵(beng)零件(jian)的(de)(de)工(gong)作臺及拆(chai)裝(zhuang)工(gong)具，切勿任(ren)意亂放(fang)亂用，避免碰壞(huai)泵(beng)的(de)(de)零部件(jian)。

　　拆對分式聯(lian)軸器(qi)(qi)：先把聯(lian)軸器(qi)(qi)的固定內六角螺釘擰(ning)下(xia)來，再(zai)(zai)輕輕把聯(lian)軸器(qi)(qi)的一半從軸上慢慢拉下(xia)，注意不要掉了，再(zai)(zai)用梅花扳手擰(ning)下(xia)泵軸吊緊螺栓和擋(dang)塊，讓葉輪慢慢下(xia)沉至泵體，然后拆下(xia)另(ling)外(wai)一半聯(lian)軸器(qi)(qi)，拿下(xia)泵軸擋(dang)圈(quan)。

　　拆卸隴縣機械密封：抓住密封彈簧順(shun)著泵軸往上提，就(jiu)能拆下來了。

　　拆卸并(bing)(bing)清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)座：先(xian)輕(qing)輕(qing)松動(dong)一下(xia)軸(zhou)(zhou)(zhou)承(cheng)座后用拆卸螺栓頂起(qi)軸(zhou)(zhou)(zhou)承(cheng)座，并(bing)(bing)且沿著泵軸(zhou)(zhou)(zhou)往上提而卸下(xia)，再(zai)用噴氣燃(ran)料清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)及(ji)座，裝(zhuang)前晾干(gan)并(bing)(bing)涂抹少(shao)許20號機械油用來潤滑保護。

　　拆(chai)密(mi)(mi)封座(zuo)：擰下密(mi)(mi)封座(zuo)壓緊螺母(mu)，輕輕卸(xie)下密(mi)(mi)封座(zuo)并清(qing)洗(xi)。

　　隴縣機械密封裝(zhuang)(zhuang)配：在(zai)動、靜環(huan)(huan)鏡面上(shang)涂一層潔(jie)凈的20號潤滑油，導軸承(cheng)座(zuo)也抹上(shang)潤滑油，先(xian)把(ba)靜環(huan)(huan)輕(qing)輕(qing)定位裝(zhuang)(zhuang)入(ru)導軸承(cheng)座(zuo)，再在(zai)泵軸上(shang)抹上(shang)潤滑油，把(ba)動環(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)(zhuang)入(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)應能(neng)伸縮自如，注意(yi)動、靜環(huan)(huan)部分的防轉部位需裝(zhuang)(zhuang)配到位。

　　裝聯(lian)(lian)(lian)軸(zhou)器：在電機軸(zhou)頭(tou)上(shang)裝上(shang)擋圈(quan)，裝上(shang)一半聯(lian)(lian)(lian)軸(zhou)器，再(zai)在泵軸(zhou)端(duan)和聯(lian)(lian)(lian)軸(zhou)器槽內(nei)裝上(shang)擋塊并用梅花扳手(shou)擰緊螺栓；再(zai)裝上(shang)另一半聯(lian)(lian)(lian)軸(zhou)器擰上(shang)內(nei)六角螺釘。安裝聯(lian)(lian)(lian)軸(zhou)器正確的檢查要求：對分式(shi)聯(lian)(lian)(lian)軸(zhou)器上(shang)下(xia)間隙需要均勻，用手(shou)盤動(dong)聯(lian)(lian)(lian)軸(zhou)器幾圈(quan)檢查轉動(dong)的靈活性。

　　裝(zhuang)(zhuang)密封座(zuo)：先(xian)將(jiang)密封座(zuo)裝(zhuang)(zhuang)入(ru)橡膠油(you)封，再(zai)把密封座(zuo)裝(zhuang)(zhuang)入(ru)泵蓋(gai)并(bing)壓(ya)(ya)在(zai)軸(zhou)承座(zuo)上，擰緊螺(luo)母，確保所有安裝(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)。當安裝(zhuang)(zhuang)螺(luo)釘(ding)被用(yong)(yong)作密封與(yu)軸(zhou)之(zhi)(zhi)間的(de)(de)驅動時(shi)，軸(zhou)應(ying)打(da)埋頭孔(kong)來(lai)加固(gu)連接(jie)，緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)應(ying)該平(ping)穩緊固(gu)，并(bing)且不要(yao)使(shi)壓(ya)(ya)蓋(gai)受(shou)彈力(li)。在(zai)可能的(de)(de)地(di)方使(shi)用(yong)(yong)4個以上螺(luo)釘(ding)的(de)(de)等間距壓(ya)(ya)蓋(gai)，緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)，用(yong)(yong)塞尺檢查軸(zhou)與(yu)壓(ya)(ya)蓋(gai)之(zhi)(zhi)間的(de)(de)間隙，這(zhe)在(zai)密封腔對壓(ya)(ya)蓋(gai)不導(dao)向(xiang)時(shi)，顯(xian)得特別(bie)重要(yao)，因(yin)為壓(ya)(ya)蓋(gai)必須對中(zhong)。
