廣河機械密封利用(yong)機械(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機械(xie)工程(cheng)中(zhong)應(ying)用(yong)非常廣泛，有多種形式，主(zhu)要包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)于(yu)(yu)大功率的(de)(de)場(chang)(chang)合(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que)，但一般要求(qiu)較(jiao)高的(de)(de)制造精(jing)度(du)和(he)安裝精(jing)度(du)。還有一類是靠機件(jian)間(jian)的(de)(de)摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易(yi)實現無(wu)級變(bian)速，可以(yi)適應(ying)軸間(jian)距較(jiao)大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而過載打滑(hua)還能起(qi)到緩沖和(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置(zhi)的(de)(de)作(zuo)用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不(bu)能用(yong)于(yu)(yu)大功率的(de)(de)場(chang)(chang)合(he)，也不(bu)能保(bao)證準確(que)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是廣河機械密封的更換工作大同(tong)小異，首先拆(chai)前需確認電機處于檢修(xiu)狀(zhuang)態，擰下加油螺(luo)塞，用吸(xi)管把密封座腔內(nei)的潤滑(hua)油吸(xi)出。準備好放(fang)置(zhi)泵零件(jian)的工作臺及拆(chai)裝工具，切勿任意(yi)亂(luan)放(fang)亂(luan)用，避免碰壞(huai)泵的零部件(jian)。

　　拆對(dui)分式聯軸器(qi)：先把聯軸器(qi)的固定內六(liu)角螺釘(ding)擰下來(lai)，再(zai)(zai)輕(qing)輕(qing)把聯軸器(qi)的一(yi)半從軸上慢慢拉(la)下，注意不(bu)要掉了，再(zai)(zai)用梅花扳手擰下泵(beng)(beng)軸吊緊螺栓和擋(dang)(dang)塊(kuai)，讓(rang)葉輪慢慢下沉至泵(beng)(beng)體，然后(hou)拆下另外一(yi)半聯軸器(qi)，拿(na)下泵(beng)(beng)軸擋(dang)(dang)圈。

　　拆卸廣河機械密封：抓住密封(feng)彈簧順著泵軸往上提(ti)，就(jiu)能拆下來了。

　　拆卸并清洗軸(zhou)(zhou)承(cheng)座(zuo)：先輕輕松動一下(xia)軸(zhou)(zhou)承(cheng)座(zuo)后用拆卸螺(luo)栓頂(ding)起軸(zhou)(zhou)承(cheng)座(zuo)，并且沿(yan)著泵軸(zhou)(zhou)往上提而卸下(xia)，再用噴氣燃料清洗軸(zhou)(zhou)承(cheng)及座(zuo)，裝前晾干并涂(tu)抹少(shao)許20號機械油(you)用來潤滑保護。

　　拆密封座：擰下密封座壓緊螺母，輕(qing)輕(qing)卸下密封座并清洗。

　　廣河機械密封裝配：在(zai)動、靜(jing)(jing)環鏡面上(shang)(shang)涂一層潔(jie)凈的20號潤(run)滑(hua)油(you)(you)，導軸承(cheng)座(zuo)也抹(mo)上(shang)(shang)潤(run)滑(hua)油(you)(you)，先把靜(jing)(jing)環輕輕定位裝入導軸承(cheng)座(zuo)，再在(zai)泵軸上(shang)(shang)抹(mo)上(shang)(shang)潤(run)滑(hua)油(you)(you)，把動環部分輕輕裝入泵軸上(shang)(shang)，用手(shou)輕推密封環應能(neng)伸縮自(zi)如(ru)，注(zhu)意動、靜(jing)(jing)環部分的防轉部位需裝配到位。

　　裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan)，裝(zhuang)(zhuang)上(shang)一半聯軸(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)端和(he)聯軸(zhou)(zhou)器(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)擋塊并(bing)用梅花扳手擰(ning)緊螺栓；再裝(zhuang)(zhuang)上(shang)另(ling)一半聯軸(zhou)(zhou)器(qi)擰(ning)上(shang)內六角螺釘。安裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)正確的檢查要(yao)求：對分式聯軸(zhou)(zhou)器(qi)上(shang)下間隙(xi)需要(yao)均(jun)勻，用手盤動聯軸(zhou)(zhou)器(qi)幾(ji)圈(quan)檢查轉動的靈活(huo)性。

　　裝密封(feng)(feng)座：先將密封(feng)(feng)座裝入橡膠油(you)封(feng)(feng)，再把(ba)密封(feng)(feng)座裝入泵(beng)蓋并(bing)壓在軸(zhou)承座上，擰緊螺母(mu)，確保(bao)所(suo)有安(an)裝螺釘緊固(gu)。當安(an)裝螺釘被用作密封(feng)(feng)與軸(zhou)之間的驅動(dong)時，軸(zhou)應打(da)埋頭孔來(lai)加(jia)固(gu)連接(jie)，緊固(gu)壓蓋螺栓時應該平穩緊固(gu)，并(bing)且不要使(shi)壓蓋受彈力(li)。在可(ke)能(neng)的地(di)方使(shi)用4個以上螺釘的等(deng)間距(ju)壓蓋，緊固(gu)壓蓋螺栓時，用塞(sai)尺檢查軸(zhou)與壓蓋之間的間隙，這在密封(feng)(feng)腔對壓蓋不導向時，顯得特(te)別重要，因為壓蓋必須對中。
