龍安機械密封利用(yong)(yong)機械方(fang)式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工程中應(ying)(ying)用(yong)(yong)非常廣泛，有多種(zhong)形式，主要包(bao)括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)(yong)于(yu)大功率(lv)(lv)的場合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一般(ban)要求較高的制造精度(du)和(he)(he)安裝(zhuang)精度(du)。還有一類(lei)是靠機件間的摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現無(wu)級變速，可以(yi)適(shi)應(ying)(ying)軸間距較大的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過(guo)載打滑還能起到緩(huan)沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的作用(yong)(yong)，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能用(yong)(yong)于(yu)大功率(lv)(lv)的場合，也不能保證準確的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是龍安機械密封的更換(huan)工作大(da)同小異，首先拆(chai)前需確認電機處(chu)于檢修狀(zhuang)態，擰下(xia)加油螺塞，用吸(xi)管把密封座腔(qiang)內(nei)的潤滑油吸(xi)出。準備好放置泵零(ling)件的工作臺及拆(chai)裝工具，切(qie)勿(wu)任(ren)意亂(luan)(luan)放亂(luan)(luan)用，避免碰壞泵的零(ling)部(bu)件。

　　拆對(dui)分式聯(lian)(lian)軸(zhou)(zhou)器(qi)：先把聯(lian)(lian)軸(zhou)(zhou)器(qi)的固定內六角螺(luo)釘擰下(xia)(xia)(xia)來，再(zai)(zai)輕輕把聯(lian)(lian)軸(zhou)(zhou)器(qi)的一半從軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia)，注意不要掉了，再(zai)(zai)用(yong)梅(mei)花扳手擰下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)吊(diao)緊螺(luo)栓和(he)擋塊，讓葉(xie)輪(lun)慢(man)慢(man)下(xia)(xia)(xia)沉至泵(beng)體，然后(hou)拆下(xia)(xia)(xia)另外一半聯(lian)(lian)軸(zhou)(zhou)器(qi)，拿下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)擋圈(quan)。

　　拆卸龍安機械密封：抓住(zhu)密封彈(dan)簧順(shun)著泵軸往上提，就(jiu)能拆(chai)下(xia)來了(le)。

　　拆卸并(bing)清洗軸(zhou)承座(zuo)：先(xian)輕(qing)輕(qing)松(song)動一(yi)下軸(zhou)承座(zuo)后用(yong)拆卸螺栓頂(ding)起軸(zhou)承座(zuo)，并(bing)且(qie)沿著泵(beng)軸(zhou)往上提而卸下，再用(yong)噴氣燃料清洗軸(zhou)承及座(zuo)，裝前晾干并(bing)涂(tu)抹(mo)少許(xu)20號機(ji)械油(you)用(yong)來潤滑保護。

　　拆密(mi)(mi)封座(zuo)(zuo)：擰下密(mi)(mi)封座(zuo)(zuo)壓緊(jin)螺母，輕輕卸下密(mi)(mi)封座(zuo)(zuo)并清洗。

　　龍安機械密封裝配：在動(dong)、靜(jing)(jing)環(huan)(huan)鏡面上(shang)(shang)涂一層(ceng)潔凈(jing)的20號潤(run)滑油，導軸承座也抹上(shang)(shang)潤(run)滑油，先把靜(jing)(jing)環(huan)(huan)輕輕定位裝入導軸承座，再在泵(beng)軸上(shang)(shang)抹上(shang)(shang)潤(run)滑油，把動(dong)環(huan)(huan)部分(fen)輕輕裝入泵(beng)軸上(shang)(shang)，用手(shou)輕推密封環(huan)(huan)應(ying)能伸縮(suo)自(zi)如，注(zhu)意動(dong)、靜(jing)(jing)環(huan)(huan)部分(fen)的防轉部位需裝配到(dao)位。

　　裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)一(yi)半(ban)聯軸(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)槽內裝(zhuang)(zhuang)上(shang)(shang)擋塊并用梅(mei)花扳手擰(ning)緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)另一(yi)半(ban)聯軸(zhou)(zhou)器(qi)擰(ning)上(shang)(shang)內六角螺釘。安(an)裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)正確的(de)(de)檢查(cha)要求(qiu)：對(dui)分式聯軸(zhou)(zhou)器(qi)上(shang)(shang)下間隙(xi)需要均勻(yun)，用手盤動聯軸(zhou)(zhou)器(qi)幾圈檢查(cha)轉動的(de)(de)靈活性。

　　裝(zhuang)密封(feng)(feng)(feng)座(zuo)：先將密封(feng)(feng)(feng)座(zuo)裝(zhuang)入橡膠油(you)封(feng)(feng)(feng)，再把(ba)密封(feng)(feng)(feng)座(zuo)裝(zhuang)入泵蓋并壓在軸(zhou)承座(zuo)上，擰緊螺(luo)(luo)母，確(que)保所有(you)安裝(zhuang)螺(luo)(luo)釘(ding)緊固(gu)(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)被(bei)用(yong)作密封(feng)(feng)(feng)與軸(zhou)之間的驅動時，軸(zhou)應打埋頭孔(kong)來加固(gu)(gu)連接，緊固(gu)(gu)壓蓋螺(luo)(luo)栓(shuan)(shuan)時應該(gai)平穩緊固(gu)(gu)，并且(qie)不(bu)要使壓蓋受彈力。在可能的地方使用(yong)4個(ge)以(yi)上螺(luo)(luo)釘(ding)的等間距壓蓋，緊固(gu)(gu)壓蓋螺(luo)(luo)栓(shuan)(shuan)時，用(yong)塞尺檢查(cha)軸(zhou)與壓蓋之間的間隙，這在密封(feng)(feng)(feng)腔對(dui)壓蓋不(bu)導(dao)向(xiang)時，顯得特(te)別重要，因為壓蓋必須對(dui)中。
