申扎機械密封利(li)用機械方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機械工程中應(ying)用非(fei)常(chang)廣泛，有多(duo)種形式(shi)，主要包括(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠(gou)用于大(da)(da)功(gong)(gong)率的(de)(de)(de)場(chang)合(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一(yi)(yi)般要求較(jiao)高的(de)(de)(de)制造精度和(he)(he)安裝精度。還有一(yi)(yi)類(lei)是靠機件間(jian)的(de)(de)(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)(ca)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實現(xian)無級變速，可以適(shi)應(ying)軸間(jian)距較(jiao)大(da)(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而過載打滑(hua)還能起到緩沖和(he)(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不能用于大(da)(da)功(gong)(gong)率的(de)(de)(de)場(chang)合(he)，也不能保(bao)證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是申扎機械密封的更換(huan)工作(zuo)大同小異，首(shou)先拆前需確(que)認電機處于檢修狀態，擰(ning)下加油(you)螺(luo)塞，用吸管把(ba)密封座(zuo)腔內的潤滑油(you)吸出。準備好放(fang)置泵零件的工作(zuo)臺及拆裝工具，切(qie)勿任意亂放(fang)亂用，避免碰壞(huai)泵的零部件。

　　拆對分(fen)式聯(lian)軸(zhou)器(qi)(qi)：先(xian)把聯(lian)軸(zhou)器(qi)(qi)的固定內(nei)六角螺釘擰下(xia)(xia)(xia)來，再(zai)輕輕把聯(lian)軸(zhou)器(qi)(qi)的一(yi)半(ban)(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia)，注(zhu)意(yi)不要掉了(le)，再(zai)用(yong)梅花扳手(shou)擰下(xia)(xia)(xia)泵軸(zhou)吊緊螺栓和擋(dang)(dang)塊，讓葉輪慢(man)慢(man)下(xia)(xia)(xia)沉至泵體，然后拆下(xia)(xia)(xia)另外一(yi)半(ban)(ban)聯(lian)軸(zhou)器(qi)(qi)，拿下(xia)(xia)(xia)泵軸(zhou)擋(dang)(dang)圈。

　　拆卸申扎機械密封：抓住密封彈(dan)簧順著泵軸往上提(ti)，就能拆下來了。

　　拆卸(xie)(xie)并清洗(xi)(xi)軸(zhou)承(cheng)座(zuo)(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)承(cheng)座(zuo)(zuo)后用(yong)拆卸(xie)(xie)螺栓頂起軸(zhou)承(cheng)座(zuo)(zuo)，并且(qie)沿著泵軸(zhou)往上提而卸(xie)(xie)下，再用(yong)噴氣燃(ran)料清洗(xi)(xi)軸(zhou)承(cheng)及(ji)座(zuo)(zuo)，裝(zhuang)前晾干并涂(tu)抹少許20號機械油用(yong)來潤滑保護。

　　拆密封(feng)座：擰下密封(feng)座壓緊螺母，輕輕卸(xie)下密封(feng)座并清洗。

　　申扎機械密封裝配：在(zai)動、靜(jing)環(huan)(huan)(huan)鏡面上(shang)涂(tu)一(yi)層潔(jie)凈的20號潤(run)滑(hua)油，導軸承(cheng)座(zuo)也抹上(shang)潤(run)滑(hua)油，先把靜(jing)環(huan)(huan)(huan)輕(qing)輕(qing)定位裝入(ru)導軸承(cheng)座(zuo)，再在(zai)泵軸上(shang)抹上(shang)潤(run)滑(hua)油，把動環(huan)(huan)(huan)部分輕(qing)輕(qing)裝入(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)(huan)應能伸縮自如，注意動、靜(jing)環(huan)(huan)(huan)部分的防轉(zhuan)部位需裝配到位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)：在電機軸(zhou)頭(tou)上(shang)(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)(shang)擋(dang)圈(quan)，裝(zhuang)上(shang)(shang)(shang)(shang)一(yi)半聯(lian)(lian)軸(zhou)器(qi)，再在泵(beng)軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)槽內裝(zhuang)上(shang)(shang)(shang)(shang)擋(dang)塊并(bing)用梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)上(shang)(shang)(shang)(shang)另一(yi)半聯(lian)(lian)軸(zhou)器(qi)擰(ning)上(shang)(shang)(shang)(shang)內六(liu)角螺釘。安(an)裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)正確的檢查要求：對分式聯(lian)(lian)軸(zhou)器(qi)上(shang)(shang)(shang)(shang)下間隙需要均勻，用手(shou)盤動聯(lian)(lian)軸(zhou)器(qi)幾(ji)圈(quan)檢查轉動的靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)(feng)(feng)座：先將密(mi)(mi)封(feng)(feng)(feng)座裝(zhuang)入橡膠(jiao)油封(feng)(feng)(feng)，再把密(mi)(mi)封(feng)(feng)(feng)座裝(zhuang)入泵蓋(gai)并壓(ya)(ya)在軸(zhou)承座上，擰緊(jin)螺母，確保所有安裝(zhuang)螺釘(ding)緊(jin)固。當(dang)安裝(zhuang)螺釘(ding)被用(yong)作密(mi)(mi)封(feng)(feng)(feng)與(yu)(yu)軸(zhou)之間的驅動時，軸(zhou)應(ying)打埋頭孔(kong)來加固連接，緊(jin)固壓(ya)(ya)蓋(gai)螺栓時應(ying)該平穩緊(jin)固，并且不要使(shi)壓(ya)(ya)蓋(gai)受彈力。在可能的地方使(shi)用(yong)4個以上螺釘(ding)的等間距壓(ya)(ya)蓋(gai)，緊(jin)固壓(ya)(ya)蓋(gai)螺栓時，用(yong)塞尺檢查(cha)軸(zhou)與(yu)(yu)壓(ya)(ya)蓋(gai)之間的間隙，這在密(mi)(mi)封(feng)(feng)(feng)腔對(dui)壓(ya)(ya)蓋(gai)不導向時，顯得特別重要，因為壓(ya)(ya)蓋(gai)必須對(dui)中(zhong)。
