射洪機械密封利(li)用(yong)(yong)機械(xie)方(fang)式(shi)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械(xie)工程中應(ying)用(yong)(yong)非常廣泛，有多種形式(shi)，主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(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。齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)(yong)于(yu)(yu)大功(gong)率的(de)(de)(de)場(chang)合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準確(que)，但一般要求(qiu)較(jiao)高(gao)的(de)(de)(de)制造精(jing)度和(he)(he)安裝(zhuang)精(jing)度。還有一類是靠機件間(jian)的(de)(de)(de)摩擦(ca)力傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)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)摩擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可(ke)以適應(ying)軸間(jian)距較(jiao)大的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而過載打滑還能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)作用(yong)(yong)，但這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)(yong)于(yu)(yu)大功(gong)率的(de)(de)(de)場(chang)合(he)，也不能(neng)保證準確(que)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是射洪機械密封的(de)更換工作(zuo)大同小異，首先拆(chai)前需確認電機處于檢修(xiu)狀態(tai)，擰下(xia)加油(you)螺塞(sai)，用吸(xi)管把密封座腔內(nei)的(de)潤滑油(you)吸(xi)出。準備(bei)好放置泵(beng)零件(jian)的(de)工作(zuo)臺及拆(chai)裝工具，切勿(wu)任(ren)意(yi)亂放亂用，避(bi)免碰(peng)壞泵(beng)的(de)零部(bu)件(jian)。

　　拆對分式聯(lian)(lian)軸(zhou)器(qi)：先把聯(lian)(lian)軸(zhou)器(qi)的固定內六角螺(luo)釘(ding)擰(ning)下(xia)(xia)來，再輕(qing)輕(qing)把聯(lian)(lian)軸(zhou)器(qi)的一半從(cong)軸(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意不(bu)要掉了，再用梅花扳(ban)手擰(ning)下(xia)(xia)泵軸(zhou)吊緊螺(luo)栓(shuan)和(he)擋(dang)塊(kuai)，讓葉輪慢(man)慢(man)下(xia)(xia)沉(chen)至泵體，然(ran)后(hou)拆下(xia)(xia)另外一半聯(lian)(lian)軸(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)擋(dang)圈。

　　拆卸射洪機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來了。

　　拆卸(xie)(xie)并(bing)清洗(xi)軸承(cheng)座：先輕(qing)輕(qing)松(song)動(dong)一下(xia)軸承(cheng)座后用拆卸(xie)(xie)螺栓頂起軸承(cheng)座，并(bing)且(qie)沿著泵軸往上提而卸(xie)(xie)下(xia)，再用噴氣燃料清洗(xi)軸承(cheng)及座，裝前晾干并(bing)涂抹少許20號機械油(you)用來潤滑保護。

　　拆密(mi)封座：擰下密(mi)封座壓緊螺母，輕(qing)輕(qing)卸(xie)下密(mi)封座并(bing)清洗。

　　射洪機械密封裝(zhuang)配：在(zai)動(dong)、靜環(huan)鏡面(mian)上涂一層潔凈的20號(hao)潤滑油(you)(you)，導(dao)軸(zhou)承座也抹(mo)上潤滑油(you)(you)，先(xian)把(ba)靜環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入導(dao)軸(zhou)承座，再(zai)在(zai)泵(beng)軸(zhou)上抹(mo)上潤滑油(you)(you)，把(ba)動(dong)環(huan)部分輕(qing)輕(qing)裝(zhuang)入泵(beng)軸(zhou)上，用手輕(qing)推密封環(huan)應(ying)能伸(shen)縮自如，注意動(dong)、靜環(huan)部分的防轉部位(wei)需裝(zhuang)配到位(wei)。

　　裝(zhuang)聯軸(zhou)器(qi)(qi)：在電機軸(zhou)頭(tou)上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋圈，裝(zhuang)上(shang)(shang)(shang)一半聯軸(zhou)器(qi)(qi)，再(zai)在泵軸(zhou)端和(he)聯軸(zhou)器(qi)(qi)槽(cao)內裝(zhuang)上(shang)(shang)(shang)擋塊并用梅(mei)花(hua)扳手擰緊(jin)螺(luo)栓；再(zai)裝(zhuang)上(shang)(shang)(shang)另一半聯軸(zhou)器(qi)(qi)擰上(shang)(shang)(shang)內六角螺(luo)釘(ding)。安(an)裝(zhuang)聯軸(zhou)器(qi)(qi)正確的(de)檢查要求：對分式聯軸(zhou)器(qi)(qi)上(shang)(shang)(shang)下間隙(xi)需要均(jun)勻，用手盤(pan)動(dong)聯軸(zhou)器(qi)(qi)幾圈檢查轉動(dong)的(de)靈活性。

　　裝(zhuang)密(mi)(mi)(mi)封座：先將密(mi)(mi)(mi)封座裝(zhuang)入橡膠油封，再(zai)把(ba)密(mi)(mi)(mi)封座裝(zhuang)入泵蓋(gai)并壓(ya)在(zai)軸(zhou)承座上，擰緊(jin)螺(luo)母，確(que)保所有(you)安裝(zhuang)螺(luo)釘(ding)緊(jin)固(gu)。當安裝(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)(mi)(mi)封與軸(zhou)之間(jian)的(de)驅(qu)動時(shi)，軸(zhou)應打埋頭孔來(lai)加(jia)固(gu)連接，緊(jin)固(gu)壓(ya)蓋(gai)螺(luo)栓(shuan)時(shi)應該(gai)平穩緊(jin)固(gu)，并且(qie)不(bu)要使壓(ya)蓋(gai)受彈力。在(zai)可能的(de)地方(fang)使用(yong)4個以上螺(luo)釘(ding)的(de)等間(jian)距壓(ya)蓋(gai)，緊(jin)固(gu)壓(ya)蓋(gai)螺(luo)栓(shuan)時(shi)，用(yong)塞尺檢查軸(zhou)與壓(ya)蓋(gai)之間(jian)的(de)間(jian)隙(xi)，這在(zai)密(mi)(mi)(mi)封腔對壓(ya)蓋(gai)不(bu)導(dao)向時(shi)，顯得特(te)別重要，因為壓(ya)蓋(gai)必須對中。
