　　傳動形式多，但是沙洋機械密封的(de)更(geng)換工作大同小異，首先拆(chai)(chai)前需確認電機(ji)處于檢修狀態，擰(ning)下加油(you)螺(luo)塞，用(yong)吸(xi)管把密封座腔內的(de)潤滑(hua)油(you)吸(xi)出(chu)。準備(bei)好放置泵零件的(de)工作臺及(ji)拆(chai)(chai)裝(zhuang)工具，切(qie)勿任意亂(luan)放亂(luan)用(yong)，避免碰壞泵的(de)零部件。

　　拆(chai)對(dui)分式聯(lian)軸器(qi)(qi)：先(xian)把(ba)聯(lian)軸器(qi)(qi)的(de)固定內六角螺釘擰下來，再輕輕把(ba)聯(lian)軸器(qi)(qi)的(de)一(yi)半(ban)從軸上慢(man)慢(man)拉下，注意不(bu)要(yao)掉了(le)，再用梅花扳手擰下泵(beng)(beng)軸吊緊螺栓和擋塊，讓葉輪慢(man)慢(man)下沉至泵(beng)(beng)體，然(ran)后拆(chai)下另外一(yi)半(ban)聯(lian)軸器(qi)(qi)，拿下泵(beng)(beng)軸擋圈。

　　拆卸沙洋機械密封：抓住密(mi)封彈簧順(shun)著(zhu)泵(beng)軸往上提(ti)，就能拆下來了。

　　拆(chai)卸(xie)并(bing)清洗軸(zhou)(zhou)承座：先輕(qing)輕(qing)松動一下軸(zhou)(zhou)承座后用(yong)拆(chai)卸(xie)螺栓頂起軸(zhou)(zhou)承座，并(bing)且沿著泵(beng)軸(zhou)(zhou)往(wang)上提而卸(xie)下，再用(yong)噴氣(qi)燃料清洗軸(zhou)(zhou)承及座，裝前(qian)晾干并(bing)涂(tu)抹少許20號機械(xie)油用(yong)來潤滑(hua)保(bao)護(hu)。

　　拆(chai)密封座(zuo)：擰下(xia)密封座(zuo)壓緊螺母，輕(qing)(qing)輕(qing)(qing)卸(xie)下(xia)密封座(zuo)并清(qing)洗(xi)。

　　沙洋機械密封裝(zhuang)配：在(zai)動、靜(jing)環(huan)(huan)(huan)鏡(jing)面上(shang)涂(tu)一層潔凈的20號潤(run)滑油，導軸承(cheng)座也抹上(shang)潤(run)滑油，先(xian)把(ba)靜(jing)環(huan)(huan)(huan)輕(qing)輕(qing)定(ding)位裝(zhuang)入(ru)導軸承(cheng)座，再在(zai)泵(beng)軸上(shang)抹上(shang)潤(run)滑油，把(ba)動環(huan)(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)入(ru)泵(beng)軸上(shang)，用手輕(qing)推密封(feng)環(huan)(huan)(huan)應能伸縮自如，注意動、靜(jing)環(huan)(huan)(huan)部分的防轉部位需裝(zhuang)配到(dao)位。

　　裝聯(lian)軸器：在電機軸頭上(shang)(shang)(shang)裝上(shang)(shang)(shang)擋(dang)圈(quan)，裝上(shang)(shang)(shang)一半(ban)(ban)聯(lian)軸器，再在泵(beng)軸端和聯(lian)軸器槽內(nei)裝上(shang)(shang)(shang)擋(dang)塊并用梅花扳手(shou)(shou)擰(ning)緊螺栓；再裝上(shang)(shang)(shang)另一半(ban)(ban)聯(lian)軸器擰(ning)上(shang)(shang)(shang)內(nei)六角螺釘。安裝聯(lian)軸器正確的(de)檢查(cha)要求：對分式聯(lian)軸器上(shang)(shang)(shang)下間隙需要均(jun)勻，用手(shou)(shou)盤(pan)動(dong)聯(lian)軸器幾圈(quan)檢查(cha)轉(zhuan)動(dong)的(de)靈活性(xing)。

　　裝(zhuang)(zhuang)密封(feng)(feng)(feng)座：先將密封(feng)(feng)(feng)座裝(zhuang)(zhuang)入橡膠油封(feng)(feng)(feng)，再把密封(feng)(feng)(feng)座裝(zhuang)(zhuang)入泵蓋(gai)(gai)(gai)(gai)(gai)并(bing)壓(ya)(ya)(ya)在軸(zhou)承座上，擰緊(jin)(jin)(jin)螺(luo)(luo)母，確(que)保(bao)所(suo)有安裝(zhuang)(zhuang)螺(luo)(luo)釘緊(jin)(jin)(jin)固(gu)。當(dang)安裝(zhuang)(zhuang)螺(luo)(luo)釘被用作密封(feng)(feng)(feng)與軸(zhou)之(zhi)間(jian)(jian)的(de)驅動(dong)時(shi)，軸(zhou)應打埋頭孔來加固(gu)連接，緊(jin)(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)螺(luo)(luo)栓時(shi)應該平穩緊(jin)(jin)(jin)固(gu)，并(bing)且不要使壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)受彈(dan)力。在可(ke)能的(de)地方(fang)使用4個以(yi)上螺(luo)(luo)釘的(de)等(deng)間(jian)(jian)距(ju)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)，緊(jin)(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)螺(luo)(luo)栓時(shi)，用塞尺(chi)檢(jian)查軸(zhou)與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙(xi)，這在密封(feng)(feng)(feng)腔(qiang)對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)不導向時(shi)，顯得特別重要，因為(wei)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)(gai)必須對中(zhong)。
