紹興機械密封利用(yong)(yong)機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應用(yong)(yong)非常廣泛，有多種(zhong)形式，主要(yao)包括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)(yong)于(yu)大功率的(de)(de)(de)場(chang)(chang)(chang)合(he)(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確(que)，但一般(ban)要(yao)求較高(gao)的(de)(de)(de)制造精(jing)度和(he)(he)安裝精(jing)度。還有一類是靠機(ji)件(jian)間的(de)(de)(de)摩(mo)擦力傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無(wu)級變(bian)速，可(ke)以(yi)適應軸間距較大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)(chang)合(he)(he)，而過(guo)載打滑(hua)還能起到緩沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作(zuo)用(yong)(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能用(yong)(yong)于(yu)大功率的(de)(de)(de)場(chang)(chang)(chang)合(he)(he)，也不能保證準確(que)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是紹興機械密封的更換工作大同小異，首先(xian)拆前(qian)需確認電機處于檢修狀(zhuang)態，擰下加油螺塞，用(yong)吸(xi)管把(ba)密封座腔內的潤滑油吸(xi)出。準備好放置泵(beng)零件的工作臺及拆裝(zhuang)工具，切(qie)勿(wu)任意亂放亂用(yong)，避免碰壞泵(beng)的零部件。

　　拆對(dui)分(fen)式聯(lian)軸器：先把聯(lian)軸器的(de)固定內六角螺釘擰下來，再輕輕把聯(lian)軸器的(de)一(yi)半從軸上(shang)慢(man)(man)慢(man)(man)拉(la)下，注(zhu)意不要掉了(le)，再用梅(mei)花扳手擰下泵(beng)軸吊緊螺栓(shuan)和擋塊，讓葉輪慢(man)(man)慢(man)(man)下沉至泵(beng)體，然后拆下另外一(yi)半聯(lian)軸器，拿(na)下泵(beng)軸擋圈(quan)。

　　拆卸紹興機械密封：抓住(zhu)密封彈(dan)簧順著泵軸往上提，就能拆下來(lai)了。

　　拆卸(xie)并清洗軸(zhou)承(cheng)座(zuo)：先輕輕松動一(yi)下軸(zhou)承(cheng)座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)承(cheng)座(zuo)，并且沿著泵(beng)軸(zhou)往上提而卸(xie)下，再(zai)用(yong)噴氣燃料清洗軸(zhou)承(cheng)及(ji)座(zuo)，裝前晾干并涂抹少許(xu)20號機械油用(yong)來潤滑保護。

　　拆(chai)密(mi)封座：擰下密(mi)封座壓緊螺母(mu)，輕輕卸下密(mi)封座并清(qing)洗。

　　紹興機械密封裝(zhuang)配：在(zai)動(dong)、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈(jing)的20號潤(run)滑(hua)油，導(dao)(dao)軸承(cheng)座也抹(mo)上(shang)潤(run)滑(hua)油，先把靜(jing)環(huan)(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入(ru)(ru)導(dao)(dao)軸承(cheng)座，再(zai)在(zai)泵軸上(shang)抹(mo)上(shang)潤(run)滑(hua)油，把動(dong)環(huan)(huan)部(bu)分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)應能伸(shen)縮自(zi)如，注(zhu)意(yi)動(dong)、靜(jing)環(huan)(huan)部(bu)分(fen)的防轉部(bu)位(wei)需(xu)裝(zhuang)配到位(wei)。

　　裝聯(lian)軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈(quan)，裝上(shang)(shang)一(yi)(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)，再(zai)在泵軸(zhou)(zhou)端(duan)和聯(lian)軸(zhou)(zhou)器(qi)槽內(nei)裝上(shang)(shang)擋塊并用梅花扳(ban)手擰(ning)緊螺栓(shuan)；再(zai)裝上(shang)(shang)另(ling)一(yi)(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)擰(ning)上(shang)(shang)內(nei)六角螺釘。安裝聯(lian)軸(zhou)(zhou)器(qi)正確的(de)檢查(cha)要求：對分式(shi)聯(lian)軸(zhou)(zhou)器(qi)上(shang)(shang)下間(jian)隙需要均勻，用手盤動聯(lian)軸(zhou)(zhou)器(qi)幾(ji)圈(quan)檢查(cha)轉動的(de)靈活性。

　　裝(zhuang)密(mi)封座：先將密(mi)封座裝(zhuang)入橡(xiang)膠(jiao)油(you)封，再把密(mi)封座裝(zhuang)入泵蓋(gai)(gai)(gai)(gai)(gai)并壓(ya)(ya)在(zai)軸(zhou)(zhou)承(cheng)座上(shang)，擰緊(jin)(jin)螺母，確保所有安裝(zhuang)螺釘緊(jin)(jin)固。當安裝(zhuang)螺釘被用作密(mi)封與(yu)軸(zhou)(zhou)之間的(de)驅動時(shi)(shi)，軸(zhou)(zhou)應打埋頭(tou)孔來加固連接，緊(jin)(jin)固壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)螺栓時(shi)(shi)應該平穩(wen)緊(jin)(jin)固，并且(qie)不要(yao)使壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)受(shou)彈力(li)。在(zai)可(ke)能的(de)地方使用4個以上(shang)螺釘的(de)等間距壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)，緊(jin)(jin)固壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)螺栓時(shi)(shi)，用塞尺檢查軸(zhou)(zhou)與(yu)壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)之間的(de)間隙，這在(zai)密(mi)封腔對壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)不導向(xiang)時(shi)(shi)，顯得特別重要(yao)，因(yin)為壓(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)必須對中。
