平昌機械密封利(li)用(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應用(yong)非常廣泛，有多種形式，主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠(gou)用(yong)于(yu)大功率的(de)場(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準(zhun)確，但(dan)一(yi)般要求較(jiao)(jiao)高的(de)制造精(jing)度和(he)(he)安裝(zhuang)精(jing)度。還有一(yi)類是靠(kao)機(ji)件間的(de)摩擦力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩擦輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級變(bian)速，可以(yi)適應軸間距較(jiao)(jiao)大的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合，而(er)過載打(da)滑(hua)還能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)作(zuo)用(yong)，但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不能(neng)用(yong)于(yu)大功率的(de)場(chang)合，也不能(neng)保證準(zhun)確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是平昌機械密封的(de)(de)更換工作(zuo)大同小異，首先拆(chai)前需確認電機處于檢修狀(zhuang)態，擰下加油螺(luo)塞，用吸(xi)(xi)管把密封座腔內的(de)(de)潤滑油吸(xi)(xi)出。準備(bei)好(hao)放(fang)置泵零件(jian)(jian)的(de)(de)工作(zuo)臺及拆(chai)裝工具(ju)，切(qie)勿任意亂(luan)放(fang)亂(luan)用，避免碰(peng)壞泵的(de)(de)零部件(jian)(jian)。

　　拆對分式聯軸器(qi)：先把(ba)聯軸器(qi)的(de)固定內六角螺釘擰下(xia)(xia)來，再輕輕把(ba)聯軸器(qi)的(de)一半從軸上慢(man)慢(man)拉下(xia)(xia)，注意不要掉了，再用梅花扳手擰下(xia)(xia)泵軸吊緊螺栓和擋塊，讓葉輪(lun)慢(man)慢(man)下(xia)(xia)沉至泵體(ti)，然后拆下(xia)(xia)另(ling)外一半聯軸器(qi)，拿下(xia)(xia)泵軸擋圈。

　　拆卸平昌機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來了。

　　拆卸并清(qing)洗(xi)軸(zhou)承(cheng)座：先輕輕松(song)動一下(xia)軸(zhou)承(cheng)座后用(yong)拆卸螺栓(shuan)頂(ding)起軸(zhou)承(cheng)座，并且沿著泵(beng)軸(zhou)往上提而卸下(xia)，再(zai)用(yong)噴氣(qi)燃料清(qing)洗(xi)軸(zhou)承(cheng)及座，裝前晾干并涂抹少(shao)許(xu)20號(hao)機械油用(yong)來潤滑(hua)保(bao)護。

　　拆密(mi)封(feng)(feng)座：擰下(xia)密(mi)封(feng)(feng)座壓緊(jin)螺母，輕(qing)輕(qing)卸下(xia)密(mi)封(feng)(feng)座并清(qing)洗。

　　平昌機械密封裝配：在動(dong)(dong)、靜(jing)環(huan)(huan)鏡面上涂一(yi)層潔凈的20號潤(run)滑(hua)油(you)(you)，導(dao)軸(zhou)承(cheng)座(zuo)也抹上潤(run)滑(hua)油(you)(you)，先把靜(jing)環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位(wei)(wei)(wei)裝入導(dao)軸(zhou)承(cheng)座(zuo)，再在泵軸(zhou)上抹上潤(run)滑(hua)油(you)(you)，把動(dong)(dong)環(huan)(huan)部分(fen)輕(qing)(qing)輕(qing)(qing)裝入泵軸(zhou)上，用手輕(qing)(qing)推密(mi)封環(huan)(huan)應能伸(shen)縮(suo)自(zi)如(ru)，注(zhu)意動(dong)(dong)、靜(jing)環(huan)(huan)部分(fen)的防轉部位(wei)(wei)(wei)需裝配到位(wei)(wei)(wei)。

　　裝(zhuang)聯(lian)(lian)(lian)軸器(qi)(qi)：在電(dian)機(ji)軸頭上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋圈(quan)，裝(zhuang)上(shang)(shang)(shang)一半聯(lian)(lian)(lian)軸器(qi)(qi)，再在泵軸端和聯(lian)(lian)(lian)軸器(qi)(qi)槽內裝(zhuang)上(shang)(shang)(shang)擋塊(kuai)并用梅花扳手(shou)擰(ning)緊螺(luo)栓(shuan)；再裝(zhuang)上(shang)(shang)(shang)另一半聯(lian)(lian)(lian)軸器(qi)(qi)擰(ning)上(shang)(shang)(shang)內六角螺(luo)釘。安(an)裝(zhuang)聯(lian)(lian)(lian)軸器(qi)(qi)正確的檢查要求：對分式聯(lian)(lian)(lian)軸器(qi)(qi)上(shang)(shang)(shang)下間(jian)隙(xi)需要均(jun)勻，用手(shou)盤動(dong)聯(lian)(lian)(lian)軸器(qi)(qi)幾(ji)圈(quan)檢查轉動(dong)的靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)座：先(xian)將密(mi)封(feng)(feng)座裝(zhuang)入(ru)橡膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座裝(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)在(zai)軸(zhou)承(cheng)座上，擰緊(jin)螺(luo)(luo)(luo)母，確保所有(you)安(an)裝(zhuang)螺(luo)(luo)(luo)釘(ding)緊(jin)固。當安(an)裝(zhuang)螺(luo)(luo)(luo)釘(ding)被用作密(mi)封(feng)(feng)與軸(zhou)之間(jian)(jian)的驅動(dong)時，軸(zhou)應打埋頭孔來加固連接，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)(luo)(luo)栓(shuan)時應該平穩緊(jin)固，并且不(bu)要使壓(ya)蓋(gai)(gai)受(shou)彈(dan)力。在(zai)可能的地方使用4個(ge)以上螺(luo)(luo)(luo)釘(ding)的等間(jian)(jian)距壓(ya)蓋(gai)(gai)，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)(luo)(luo)栓(shuan)時，用塞(sai)尺(chi)檢查(cha)軸(zhou)與壓(ya)蓋(gai)(gai)之間(jian)(jian)的間(jian)(jian)隙，這(zhe)在(zai)密(mi)封(feng)(feng)腔對壓(ya)蓋(gai)(gai)不(bu)導(dao)向時，顯(xian)得(de)特別重要，因為壓(ya)蓋(gai)(gai)必須對中。
