達川機械密封利用(yong)(yong)(yong)機(ji)械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工程(cheng)中(zhong)應用(yong)(yong)(yong)非常(chang)廣泛，有多種形式，主要包(bao)括(kuo)皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和螺(luo)旋(xuan)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)(yong)(yong)于大(da)功率(lv)的場合(he)，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一(yi)般要求較高(gao)的制(zhi)造精度和安裝精度。還有一(yi)類是靠(kao)機(ji)件間的摩(mo)擦力(li)傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)的摩(mo)擦傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和摩(mo)擦輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無(wu)級變速，可以適應軸間距較大(da)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合(he)，而(er)過(guo)載打滑還能起到(dao)緩沖和保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置(zhi)的作用(yong)(yong)(yong)，但(dan)這(zhe)種傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不(bu)(bu)能用(yong)(yong)(yong)于大(da)功率(lv)的場合(he)，也不(bu)(bu)能保證準確的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是達川機械密封的更(geng)換工作(zuo)大同小異(yi)，首先拆(chai)前需確認電機處于檢修狀態，擰下加油螺塞(sai)，用(yong)(yong)吸管把密封座腔內的潤滑油吸出。準備(bei)好放置泵零件(jian)的工作(zuo)臺及拆(chai)裝工具，切勿任意亂(luan)放亂(luan)用(yong)(yong)，避免碰壞(huai)泵的零部件(jian)。

　　拆對(dui)分式(shi)聯(lian)軸(zhou)器：先把(ba)(ba)聯(lian)軸(zhou)器的固定內(nei)六角螺(luo)釘擰下(xia)(xia)(xia)來，再輕輕把(ba)(ba)聯(lian)軸(zhou)器的一半從(cong)軸(zhou)上慢慢拉下(xia)(xia)(xia)，注意不要(yao)掉了，再用梅花扳手(shou)擰下(xia)(xia)(xia)泵軸(zhou)吊(diao)緊螺(luo)栓和擋塊，讓葉(xie)輪慢慢下(xia)(xia)(xia)沉至泵體，然后拆下(xia)(xia)(xia)另外(wai)一半聯(lian)軸(zhou)器，拿下(xia)(xia)(xia)泵軸(zhou)擋圈。

　　拆卸達川機械密封：抓住密封彈簧順著泵軸往上提，就能(neng)拆下(xia)來了(le)。

　　拆(chai)卸(xie)(xie)(xie)并清(qing)洗軸承(cheng)座：先(xian)輕輕松動一下軸承(cheng)座后用拆(chai)卸(xie)(xie)(xie)螺栓頂起(qi)軸承(cheng)座，并且(qie)沿著泵軸往上(shang)提(ti)而卸(xie)(xie)(xie)下，再用噴(pen)氣燃料清(qing)洗軸承(cheng)及(ji)座，裝前晾干并涂抹少許20號機械油用來潤滑(hua)保(bao)護。

　　拆(chai)密(mi)封座(zuo)：擰下(xia)密(mi)封座(zuo)壓緊(jin)螺母(mu)，輕輕卸(xie)下(xia)密(mi)封座(zuo)并清洗。

　　達川機械密封裝(zhuang)配：在動、靜環鏡面上涂一(yi)層潔凈的(de)20號潤滑油，導軸承(cheng)座也抹(mo)(mo)上潤滑油，先(xian)把靜環輕(qing)(qing)(qing)(qing)輕(qing)(qing)(qing)(qing)定位裝(zhuang)入導軸承(cheng)座，再在泵(beng)軸上抹(mo)(mo)上潤滑油，把動環部分輕(qing)(qing)(qing)(qing)輕(qing)(qing)(qing)(qing)裝(zhuang)入泵(beng)軸上，用手輕(qing)(qing)(qing)(qing)推密(mi)封環應能伸縮自(zi)如，注意動、靜環部分的(de)防轉部位需裝(zhuang)配到位。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在(zai)電(dian)機軸(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan)，裝(zhuang)(zhuang)上(shang)一半聯(lian)軸(zhou)器(qi)(qi)，再(zai)在(zai)泵軸(zhou)端和聯(lian)軸(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)上(shang)擋塊(kuai)并(bing)用(yong)梅(mei)花扳(ban)手(shou)(shou)擰緊螺栓(shuan)；再(zai)裝(zhuang)(zhuang)上(shang)另一半聯(lian)軸(zhou)器(qi)(qi)擰上(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)正確(que)的(de)檢(jian)查(cha)要求(qiu)：對(dui)分式聯(lian)軸(zhou)器(qi)(qi)上(shang)下間隙(xi)需要均勻(yun)，用(yong)手(shou)(shou)盤動(dong)聯(lian)軸(zhou)器(qi)(qi)幾圈(quan)檢(jian)查(cha)轉(zhuan)動(dong)的(de)靈(ling)活性。

　　裝密(mi)封座(zuo)：先將密(mi)封座(zuo)裝入橡膠油封，再把密(mi)封座(zuo)裝入泵蓋(gai)(gai)并壓(ya)(ya)在軸承座(zuo)上，擰緊(jin)(jin)螺(luo)(luo)母，確保(bao)所有安裝螺(luo)(luo)釘(ding)緊(jin)(jin)固(gu)(gu)。當(dang)安裝螺(luo)(luo)釘(ding)被(bei)用(yong)作密(mi)封與(yu)軸之(zhi)間的(de)驅動時，軸應打埋(mai)頭(tou)孔來(lai)加(jia)固(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓時應該平穩緊(jin)(jin)固(gu)(gu)，并且不要使(shi)壓(ya)(ya)蓋(gai)(gai)受彈(dan)力。在可能的(de)地方使(shi)用(yong)4個以上螺(luo)(luo)釘(ding)的(de)等(deng)間距壓(ya)(ya)蓋(gai)(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓時，用(yong)塞(sai)尺檢查(cha)軸與(yu)壓(ya)(ya)蓋(gai)(gai)之(zhi)間的(de)間隙，這(zhe)在密(mi)封腔對壓(ya)(ya)蓋(gai)(gai)不導向時，顯得(de)特別(bie)重要，因(yin)為壓(ya)(ya)蓋(gai)(gai)必須對中。
