桑珠孜機械密封利用機(ji)械方式(shi)(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(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(zai)機(ji)械工(gong)程中應用非常(chang)廣(guang)泛,有多(duo)種形式(shi)(shi),主要包(bao)括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(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)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)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。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用于(yu)大(da)(da)功率(lv)的(de)(de)場(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確,但一(yi)般要求(qiu)較高(gao)的(de)(de)制造(zao)精(jing)度(du)和(he)(he)安(an)裝(zhuang)精(jing)度(du)。還(huan)有一(yi)類是靠機(ji)件間(jian)的(de)(de)摩擦力(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包(bao)括帶(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)摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變速,可(ke)以(yi)適應軸間(jian)距較大(da)(da)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)合,而過載打滑還(huan)能起到緩(huan)沖和(he)(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)作用,但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)般不能用于(yu)大(da)(da)功率(lv)的(de)(de)場(chang)合,也不能保(bao)證準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。
傳動形式多,但是桑珠孜機械密封的(de)(de)更換工作大(da)同小異,首先拆前需確(que)認電機(ji)處于(yu)檢(jian)修狀態,擰下(xia)加油(you)螺塞,用(yong)吸管把密封座腔內的(de)(de)潤(run)滑(hua)油(you)吸出。準備好(hao)放(fang)置泵(beng)零(ling)件(jian)的(de)(de)工作臺及(ji)拆裝工具,切勿任(ren)意亂(luan)放(fang)亂(luan)用(yong),避(bi)免碰(peng)壞泵(beng)的(de)(de)零(ling)部件(jian)。
拆對(dui)分式聯(lian)(lian)軸(zhou)器:先把聯(lian)(lian)軸(zhou)器的固定內六角(jiao)螺釘擰下(xia)(xia)(xia)來,再輕輕把聯(lian)(lian)軸(zhou)器的一半從軸(zhou)上慢(man)(man)慢(man)(man)拉(la)下(xia)(xia)(xia),注意不(bu)要(yao)掉(diao)了(le),再用梅(mei)花扳(ban)手(shou)擰下(xia)(xia)(xia)泵軸(zhou)吊緊螺栓和擋塊,讓葉輪慢(man)(man)慢(man)(man)下(xia)(xia)(xia)沉至泵體,然后拆下(xia)(xia)(xia)另外一半聯(lian)(lian)軸(zhou)器,拿下(xia)(xia)(xia)泵軸(zhou)擋圈。
拆卸桑珠孜機械密封:抓(zhua)住密封彈簧順著泵軸往上提(ti),就能拆下(xia)來(lai)了。
拆卸并(bing)清洗(xi)軸(zhou)(zhou)承(cheng)座(zuo):先輕輕松動一下(xia)軸(zhou)(zhou)承(cheng)座(zuo)后(hou)用拆卸螺栓頂起軸(zhou)(zhou)承(cheng)座(zuo),并(bing)且(qie)沿(yan)著(zhu)泵(beng)軸(zhou)(zhou)往(wang)上提而卸下(xia),再用噴(pen)氣(qi)燃料清洗(xi)軸(zhou)(zhou)承(cheng)及座(zuo),裝前晾(liang)干并(bing)涂(tu)抹少許(xu)20號機械油用來(lai)潤滑保護(hu)。
拆(chai)密(mi)封(feng)座(zuo):擰下(xia)密(mi)封(feng)座(zuo)壓緊螺(luo)母,輕(qing)(qing)輕(qing)(qing)卸下(xia)密(mi)封(feng)座(zuo)并(bing)清洗(xi)。
桑珠孜機械密封裝(zhuang)配:在動(dong)、靜(jing)(jing)環鏡面上(shang)涂一層潔(jie)凈的(de)20號(hao)潤(run)(run)滑油,導(dao)軸(zhou)(zhou)(zhou)承座也抹(mo)上(shang)潤(run)(run)滑油,先把靜(jing)(jing)環輕(qing)輕(qing)定位裝(zhuang)入導(dao)軸(zhou)(zhou)(zhou)承座,再在泵(beng)軸(zhou)(zhou)(zhou)上(shang)抹(mo)上(shang)潤(run)(run)滑油,把動(dong)環部分輕(qing)輕(qing)裝(zhuang)入泵(beng)軸(zhou)(zhou)(zhou)上(shang),用手輕(qing)推(tui)密(mi)封(feng)環應能伸(shen)縮自如,注意動(dong)、靜(jing)(jing)環部分的(de)防轉(zhuan)部位需裝(zhuang)配到位。
裝(zhuang)(zhuang)聯軸器(qi):在電機軸頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan),裝(zhuang)(zhuang)上(shang)一半聯軸器(qi),再(zai)(zai)在泵(beng)軸端(duan)和(he)聯軸器(qi)槽內(nei)(nei)裝(zhuang)(zhuang)上(shang)擋塊(kuai)并用(yong)梅(mei)花扳手擰緊螺栓;再(zai)(zai)裝(zhuang)(zhuang)上(shang)另一半聯軸器(qi)擰上(shang)內(nei)(nei)六角(jiao)螺釘。安裝(zhuang)(zhuang)聯軸器(qi)正確的(de)檢(jian)查要(yao)求(qiu):對(dui)分式(shi)聯軸器(qi)上(shang)下間(jian)隙(xi)需要(yao)均勻,用(yong)手盤(pan)動聯軸器(qi)幾圈(quan)檢(jian)查轉動的(de)靈(ling)活性(xing)。
裝密(mi)(mi)封座(zuo)(zuo):先將密(mi)(mi)封座(zuo)(zuo)裝入橡(xiang)膠油封,再(zai)把密(mi)(mi)封座(zuo)(zuo)裝入泵蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)在(zai)(zai)軸承(cheng)座(zuo)(zuo)上,擰緊(jin)(jin)螺(luo)(luo)母,確(que)保所有安(an)裝螺(luo)(luo)釘(ding)緊(jin)(jin)固(gu)。當安(an)裝螺(luo)(luo)釘(ding)被用作(zuo)密(mi)(mi)封與(yu)軸之(zhi)間(jian)的驅動時(shi),軸應(ying)打埋頭孔來加固(gu)連接,緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)應(ying)該平穩緊(jin)(jin)固(gu),并(bing)且不(bu)要使壓(ya)(ya)蓋(gai)(gai)(gai)受彈(dan)力。在(zai)(zai)可能(neng)的地方使用4個(ge)以上螺(luo)(luo)釘(ding)的等間(jian)距(ju)壓(ya)(ya)蓋(gai)(gai)(gai),緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi),用塞尺(chi)檢(jian)查軸與(yu)壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)的間(jian)隙(xi),這在(zai)(zai)密(mi)(mi)封腔對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi),顯得特別重要,因為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中。
