金寨機械密封利用(yong)機械(xie)(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機械(xie)(xie)工程中應用(yong)非常廣泛(fan)，有多(duo)種形式(shi)，主要(yao)包括皮帶(dai)(dai)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(gua)桿(gan)蝸(gua)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(xuan)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率(lv)的(de)場合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準(zhun)確(que)(que)，但一般要(yao)求較(jiao)(jiao)高的(de)制造精度和(he)(he)安裝精度。還有一類是靠(kao)機件間的(de)摩(mo)擦力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩(sheng)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。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變(bian)速，可以適應軸間距較(jiao)(jiao)大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過載打滑還能起(qi)到(dao)緩沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作(zuo)用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不(bu)能用(yong)于大(da)功率(lv)的(de)場合，也不(bu)能保證準(zhun)確(que)(que)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是金寨機械密封的更換(huan)工作大同(tong)小異，首先拆前(qian)需(xu)確認電機處于(yu)檢修(xiu)狀(zhuang)態，擰下(xia)加(jia)油螺塞，用吸管把密(mi)封座(zuo)腔內的潤滑油吸出。準備好放置泵零(ling)件的工作臺(tai)及拆裝工具，切(qie)勿任意(yi)亂(luan)(luan)放亂(luan)(luan)用，避(bi)免碰壞泵的零(ling)部件。

　　拆對分式聯(lian)軸(zhou)器(qi)(qi)：先(xian)把(ba)聯(lian)軸(zhou)器(qi)(qi)的固定內六角螺釘(ding)擰(ning)下(xia)(xia)來，再(zai)(zai)輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)(qi)的一半(ban)從軸(zhou)上慢(man)慢(man)拉(la)下(xia)(xia)，注意不要掉了(le)，再(zai)(zai)用梅花扳(ban)手擰(ning)下(xia)(xia)泵(beng)軸(zhou)吊緊螺栓和擋(dang)塊(kuai)，讓葉輪慢(man)慢(man)下(xia)(xia)沉至泵(beng)體，然(ran)后拆下(xia)(xia)另外(wai)一半(ban)聯(lian)軸(zhou)器(qi)(qi)，拿(na)下(xia)(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸金寨機械密封：抓住密封彈簧順著(zhu)泵軸往上提，就能拆下來(lai)了。

　　拆卸并清(qing)洗軸承座(zuo)：先輕(qing)輕(qing)松動一下(xia)軸承座(zuo)后(hou)用(yong)(yong)拆卸螺栓頂起軸承座(zuo)，并且沿(yan)著泵軸往(wang)上提而(er)卸下(xia)，再用(yong)(yong)噴氣燃(ran)料清(qing)洗軸承及座(zuo)，裝前晾(liang)干并涂(tu)抹少許(xu)20號機械油(you)用(yong)(yong)來潤滑保護。

　　拆密封座：擰(ning)下密封座壓緊螺(luo)母，輕輕卸下密封座并清洗。

　　金寨機械密封裝(zhuang)(zhuang)配(pei)：在(zai)動(dong)、靜環(huan)鏡面上(shang)涂一(yi)層潔凈(jing)的(de)20號潤(run)滑油，導軸(zhou)承座也抹上(shang)潤(run)滑油，先(xian)把(ba)靜環(huan)輕輕定位裝(zhuang)(zhuang)入導軸(zhou)承座，再在(zai)泵(beng)軸(zhou)上(shang)抹上(shang)潤(run)滑油，把(ba)動(dong)環(huan)部分輕輕裝(zhuang)(zhuang)入泵(beng)軸(zhou)上(shang)，用手輕推密封環(huan)應能伸縮(suo)自如，注(zhu)意動(dong)、靜環(huan)部分的(de)防(fang)轉部位需(xu)裝(zhuang)(zhuang)配(pei)到(dao)位。

　　裝(zhuang)聯軸(zhou)器(qi)：在電機軸(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋圈，裝(zhuang)上(shang)(shang)一半聯軸(zhou)器(qi)，再在泵軸(zhou)端和聯軸(zhou)器(qi)槽內(nei)裝(zhuang)上(shang)(shang)擋塊并用梅花扳手擰緊螺(luo)栓；再裝(zhuang)上(shang)(shang)另一半聯軸(zhou)器(qi)擰上(shang)(shang)內(nei)六角螺(luo)釘(ding)。安(an)裝(zhuang)聯軸(zhou)器(qi)正確(que)的檢查要求：對分式聯軸(zhou)器(qi)上(shang)(shang)下間隙需要均勻，用手盤動聯軸(zhou)器(qi)幾圈檢查轉動的靈(ling)活性。

　　裝(zhuang)密封(feng)(feng)座(zuo)：先將密封(feng)(feng)座(zuo)裝(zhuang)入橡膠(jiao)油封(feng)(feng)，再(zai)把密封(feng)(feng)座(zuo)裝(zhuang)入泵蓋并壓(ya)在(zai)軸(zhou)(zhou)承座(zuo)上(shang)，擰緊(jin)螺母，確保所(suo)有安裝(zhuang)螺釘緊(jin)固(gu)。當安裝(zhuang)螺釘被用作密封(feng)(feng)與軸(zhou)(zhou)之間的驅動(dong)時，軸(zhou)(zhou)應打埋(mai)頭(tou)孔來(lai)加固(gu)連接，緊(jin)固(gu)壓(ya)蓋螺栓時應該平穩緊(jin)固(gu)，并且不要(yao)使壓(ya)蓋受彈(dan)力。在(zai)可能的地方使用4個以上(shang)螺釘的等(deng)間距壓(ya)蓋，緊(jin)固(gu)壓(ya)蓋螺栓時，用塞尺檢查軸(zhou)(zhou)與壓(ya)蓋之間的間隙，這在(zai)密封(feng)(feng)腔(qiang)對壓(ya)蓋不導向時，顯得特別重要(yao)，因為(wei)壓(ya)蓋必須對中(zhong)。
