Pampu Mechanical Seal Kutayikira Zomwe Zimayambitsa
Makina osindikizira amadziwikanso kuti chisindikizo chakumapeto, chomwe chili ndi nkhope zomapeto zomwe zimayenderana ndi nsonga yozungulira, nkhope yomaliza pansi pa mphamvu yamadzimadzi komanso kubwezera mphamvu yamakina akunja, kutengera kulumikizana kwa chisindikizo chothandizira ndi chisindikizo chothandizira. mapeto ena kuti akhale oyenera, ndi wachibale Wopanda, kuteteza kutayikira madzimadzi. Credo Pump ikufotokozera mwachidule zomwe zimayambitsa kutayikira komwe kumachititsa kuti pampu yamadzi isindikize:
Common kutayikira chodabwitsa
Kuchuluka kwa kutayikira kwa makina osindikizira kumapitilira 50% ya mapampu onse okonza. Kugwira ntchito kwa makina osindikizira kumakhudza mwachindunji ntchito yachibadwa ya mpope. Imawunikiridwa ndikuwunikidwa motere:
1. Kutaya nthawi
Pump rotor shaft channel liwiro, chisindikizo chothandizira ndi kusokoneza kwakukulu kwa shaft, mphete yosuntha sichitha kusuntha pamtengowo, pamene pampu imatembenuzidwa, kuvala kwa mphete zosunthika komanso zosasunthika, palibe kubweza.
Njira zothanirana nazo: Pakuphatikiza chisindikizo cha makina, kuthamanga kwa shaft kwa shaft kuyenera kukhala kosakwana 0.1mm, ndipo kusokoneza pakati pa chisindikizo chothandizira ndi shaft kuyenera kukhala kocheperako. Poonetsetsa kuti chisindikizo cha radial, mphete yosunthika imatha kusunthidwa pamtengowo pambuyo pa kusonkhana (mphete yosunthikayo imatha kubwezeredwa momasuka ku kasupe).
2. Mafuta opaka mafuta osakwanira pamtunda wosindikizira amayambitsa kukangana kouma kapena kujambula chisindikizo kumapeto.
Countermeasures: Kutalika kwa mafuta opaka mafuta m'chipinda chamafuta kuyenera kukhala kokulirapo kuposa malo osindikizira a mphete zoyenda komanso zosasunthika.
3. Kugwedezeka kwanthawi kwa rotor. Chifukwa chake ndi chakuti stator ndi pamwamba ndi m'munsi mapeto chimakwirira musati bwino impeller ndi spindle, cavitation kapena kubala kuwonongeka (kuvala), izi adzafupikitsa kusindikiza moyo ndi kutayikira.
Countermeasures: Mavuto omwe ali pamwambawa amatha kuwongoleredwa molingana ndi miyezo yosamalira.
Kutayikira chifukwa cha kukakamizidwa
1. Kutayikira kwamakina osindikizira chifukwa cha kuthamanga kwambiri komanso kuthamanga kwa mafunde chifukwa cha kukakamiza kwakukulu kwa kasupe komanso kapangidwe kake kakanikizidwe kake komanso kukakamiza kwachipinda chosindikizira kupitilira 3MPa, kumapangitsa kukakamiza kwenikweni pamapeto osindikiza kukhala kwakukulu, ndikupangitsa kuti zikhale zovuta. kuti filimu yamadzimadzi ipangidwe, kuvala kwambiri kumapeto kwa nkhope yosindikizira, kuwonjezeka kwa calorific ndipo kumapangitsa kuti pakhale kutentha kwa malo osindikizira.
Countermeasures: mu chosindikizira makina msonkhano, psinjika kasupe kuyenera kuchitidwa molingana ndi zomwe zaperekedwa, musalole chodabwitsa chachikulu kapena chaching'ono kwambiri, kupanikizika kwakukulu pansi pa chisindikizo cha makina kuyenera kuchitapo kanthu. Kuti mapeto nkhope mphamvu wololera, mmene ndingathere kuchepetsa mapindikidwe, angagwiritse ntchito aloyi zolimba, zoumba ndi zipangizo ndi mkulu compressive mphamvu, ndi kulimbitsa kuzirala kondomu miyeso, kusankha kufala akafuna, monga kiyi, pini, ndi zina.
2. Vacuum mpope makina osindikizira kutayikira chifukwa cha ntchito poyambira, kuyimitsa, chifukwa cha kutsekeka kwa mpope polowera, kupopera sing'anga yomwe ili ndi mpweya, kungayambitse kutsekeka kwa chisindikizo, zibowo zosindikizira ngati kupanikizika koyipa, kukangana kowuma. zimayambitsa zisindikizo, anamanga-mtundu makina chisindikizo adzatulutsa (madzi) cha kutayikira chodabwitsa, zingalowe chisindikizo ndi kusiyana zabwino kuthamanga chisindikizo chisindikizo mbali ya chinthu, ndi kusinthasintha kwa makina chisindikizo ali ndi malangizo.
Countermeasure: gwiritsani ntchito chisindikizo chakumapeto kwapawiri, ndizothandiza kukonza mawonekedwe amafuta ndi kusindikiza.
Kutayikira chifukwa cha sing'anga
1. Zambiri za submersible pump mechanical seal dismantling, static ring and move ring aid sindikiza ndi inelastic, zina zavunda, zomwe zimapangitsa kuti makina osindikizira awonongeke kwambiri komanso ngakhale kugaya shaft phenomenon. Chifukwa cha kutentha kwambiri, asidi ofooka m'zimbudzi, ofooka m'munsi pa mphete yosasunthika ndi kusuntha kwa mphete yothandizira labala, zomwe zimapangitsa kuti makina atayike ndi aakulu kwambiri, osunthika komanso osakanikirana ndi mphete ya nitrile - 40, kutentha kwambiri, acid. -alkali kugonjetsedwa, pamene zimbudzi ndi acidic ndi zamchere zosavuta dzimbiri.
Zotsutsana nazo: kuzinthu zowonongeka, zigawo za mphira ziyenera kukhala zosagwira kutentha, kufooka kwa asidi, kufooka kwa alkali fluororubber.
2. Mawotchi chisindikizo kutayikira chifukwa olimba tinthu zosafunika. Ngati particles olimba mu chisindikizo chisindikizo, adzadulidwa kapena kufulumizitsa zisindikizo za kutha ndi kung'ambika, sikelo ndi kudzikundikira mafuta pamwamba pa kutsinde (anaika), pa mlingo mofulumira kuposa avale mlingo wa mikangano awiri, mphete akhoza 't amalipiritsa kusamutsidwa abrasion, zovuta mikangano awiri ntchito yaitali kuposa molimba graphite mikangano awiri, chifukwa cha particles olimba ndi ophatikizidwa graphite kusindikiza mphete kusindikiza pamwamba.
Countermeasure: Chisindikizo cha makina a tungsten carbide friction pair chiyenera kusankhidwa pamalo omwe tinthu zolimba ndizosavuta kulowa.
Chifukwa cha zovuta zina zomwe zimayambitsidwa ndi kutayikira kwa makina osindikizira zisindikizo zamakina akadalipo pamapangidwe, kusankha, kuyika ndi malo ena opanda pake.
1. Kuponderezedwa kwa kasupe kuyenera kuchitidwa motsatira malamulo, ndipo sikuloledwa kukhala kwakukulu kapena kochepa kwambiri. Cholakwika ndi ± 2mm.
2. Kumapeto kwa shaft (kapena mkono wa shaft) kuika mphete yosindikizira yosunthika ndi kumapeto kwa chigoba chosindikizira (kapena chipolopolo) kuika mphete yosindikizira yokhazikika kuyenera kupukuta ndi kupukutidwa kupeŵa kuwonongeka kwa mphete yosindikizira yomwe siyimayima panthawi yosonkhanitsa.
