Chifukwa Chiyani Mugwiritsire Ntchito The Bellows Seling Globe Valve Pakutumiza Mafuta Kutentha?

Kutentha mafuta kutumizandi mtundu wamafuta apadera okhala ndi kukhazikika kwamafuta abwino omwe amagwiritsidwa ntchito potengera kutentha kosalunjika.Kutentha conduction mafuta sangathe kukumana Kutentha ndi kuzirala zofunika ndondomeko ya kutentha osiyanasiyana osiyanasiyana kutentha, komanso kuzindikira ndondomeko zofunika Kutentha kutentha ndi otsika kutentha kuzirala ndi yemweyo kutentha conduction mafuta mu dongosolo lomwelo, amene angathe kuchepetsa zovuta za dongosolo ndi ntchito.Chifukwa chake, makina opangira mafuta opangira kutentha amagwiritsidwa ntchito kwambiri muzamankhwala, zinthu ndi mafakitale ena.
Makhalidwe a system conduction mafuta:
1.Pansi pa chikhalidwe cha kupanikizika kwa mlengalenga, amatha kupeza kutentha kwapamwamba kwambiri - ndiko kuti, kungachepetse kwambiri kupanikizika kwa ntchito ndi zofunikira za chitetezo cha kutentha kwa kutentha kwa kutentha, kukonza kudalirika kwa dongosolo ndi zipangizo;
2. Makina opangira mafuta otenthetsera kutentha amasiya njira yopangira madzi ndi zida, zomwe zimathandizira kutenthetsa kwadongosolo ndikuchepetsa ntchito yokonza zida ndi mapaipi - ndiko kuti, ndalama zoyambira ndi ndalama zogwiritsira ntchito makina otenthetsera. kuchepetsedwa.

Zowopsa zomwe zingachitike pakugwira ntchito kwamafuta amafuta:
1.Chifukwa cha kutenthedwa kwapakati pa kutentha kwapakati pa nthawi yogwiritsira ntchito mafuta opangira kutentha, kutentha kwa kutentha kumakhala kosavuta kuchitika, zomwe zimapangitsa kuti oligomers awonongeke komanso otsika.Polymerization pakati pa oligomers umapanga ma polima osasungunuka komanso osasungunuka, omwe samalepheretsa kutulutsa kwamafuta komanso kumachepetsa kutentha komweko, komanso kumapangitsa kuti pakhale kutentha kwapang'onopang'ono komanso kuphulika kwa payipi.
2. Mafuta otengera kutentha ndi kusungunuka kwa mpweya ndi kudzazidwa kwa chonyamulira kutentha ndi momwe ma oxidation amachitira mpweya wotsalira pansi pa kutentha, ndipo mapangidwe a organic acid ndi colloid amatsatira payipi yamafuta, zomwe sizimangokhudza moyo wautumiki wa sing'anga yotengera kutentha ndi kutentha. imalepheretsa payipi, komanso imayambitsa kuwonongeka kwa payipi mosavuta ndikuwonjezera chiopsezo cha kutayikira kwa ntchito.
Ngozi za makina otenthetsera mafuta otengera kutentha ndi awa:moto wa kusanjikiza zotenthetsera kutentha, moto wowonjezera thanki utsi ndi kutentha kutentha wosanjikiza, moto wa kutentha kutengerapo mafuta dongosolo ntchito malo, moto ndi kuphulika kwa kutentha kutengerapo thanki yosungirako mafuta, moto ndi kuphulika kwa kutentha kutengerapo mafuta exchanger kutentha exchanger kapena riyakitala (ketulo), Kuphulika kwa ng'anjo, ndi zina zotero. Zingawonekere kuti ngozi zambiri zomwe zimawotcha mafuta otenthetsera zimakhala zowonjezereka zokhudzana ndi kutayikira.
Zofunikira za ma vavu pamakina aukadaulo ndi kapangidwe kawo pamakina amafuta otentha ndi awa: an valve yotulutsa mpweyapamalo okwera kwambiri komanso valavu yophulitsira pamalo otsika kwambiri.Mzere wa chitoliro cha dongosolo la mafuta otentha uyenera kulumikizidwa ndiflangeskupatula zolumikizira zida, zolumikizira zida kapena mavavu.Ma interfaces ena onse ndi welded.Theflangeiyenera kukhazikitsidwa poyambira, ndipo kuthamanga mwadzina kuyenera kukhala kosachepera 1.6MPa.Pakuti kutentha conduction mafuta ndi kutentha kuposa madigiri 300, kuthamanga mwadzina waflangesayenera kuchepera 2.5MPa.Flangesziyenera kukhala zowotcherera m'malo mwa ma flanges okhotakhota.Flange gasket yamafuta otentha saloledwa kugwiritsa ntchito mbale ya mphira ya asibesitosi, zitsulo zomangira zitsulo kapena graphite composite pad iyenera kugwiritsidwa ntchito.Dongosolo lamafuta otentha liyenera kuperekedwa ndi valavu yotetezera, ndipo valavu yachitetezo iyenera kukhala valavu yosindikizidwa yotetezedwa.
Zida za valve za dongosolo lamafuta otentha siziyenera kuponyedwa chitsulo kapena zitsulo zopanda chitsulo.Poganizira kutsika kwake, kutentha kwakukulu komanso kutha kwake kumakhala kolimba kwambiri, malinga ndi momwe mayendedwe aukadaulo amapangidwira, payipi yotentha yamafuta odulira valavu iyenera kugwiritsa ntchito valavu ya bellows seal, valavu yowongolera iyenera kugwiritsa ntchito valavu yoyang'anira valavu yosindikizira. valavu yotseka yotseka yotseka yotseka.

Chifukwa cha kukhazikika kwa oxidation yamafuta oyendetsa kutentha, kutayikira kwa valavu yamafuta otentha sikungoyambitsa kuyaka kwa wosanjikiza kapena kuyaka ndi kuphulika kwa zida, komanso kumayambitsa makutidwe ndi okosijeni wamafuta oyendetsa kutentha ndi kusungunuka mpweya mu kutentha, kutulutsa organic acid dzimbiri mavavu mkati.Chifukwa chake valavu yamafuta otentha sayenera kungochita kutulutsa kwamkati, komanso kusatulutsa kunja.
General kulongedza padziko lonse valavu kulongedza katundu ndi graphite akamaumba processing, ngati chiyero graphite sikokwanira, kukana mafuta ake adzakhala osauka kwambiri, pamene kutentha conduction mafuta mu graphite kulongedza katundu, zonyansa zina mu graphite n'zosavuta kusungunuka ndi conduction kutentha. mafuta, chifukwa graphite ufa, sangakhoze kulongedza graphite kulongedza katundu kukwaniritsa kusindikiza kwenikweni, ichi ndi chifukwa chachikulu cha kunyamula valavu zambiri kutayikira.Chisindikizo cha bellows chimalepheretsa kukhudzana kwachindunji pakati pa mafuta otentha ndi graphite, zomwe zimathetsa vuto la mafuta otentha kutuluka patsinde pamene graphite packing isungunuka.
Chifukwa permeability wa mafuta conduction kutentha ndi wamphamvu kwambiri (pafupifupi 50 nthawi nthunzi), ngati filler chisindikizo chosankhidwa, n'zosavuta kutulutsa, kubweretsa kuwononga mafuta otentha, zida zauve ndi nthaka, ndi mavuvu. amatha kuzindikira kutayikira kwa zero, komanso osavala zida.
Chifukwa cha kuopsa kwa kukhazikika kwa okosijeni kwa mafuta oyendetsa kutentha, mbali zamkati za valavu zimapangidwa ndi chitsulo chosapanga dzimbiri, chomwe chimatha kupirira kutentha kwa 425 ℃, kukana kwa dzimbiri, ndipo kusintha kumakhala kosavuta.

Kuchokera pamalingaliro amoyo wonse, moyo wautumiki wa wambavalavu yosindikiza mivuvundi bwino kuposa mavavu ena.Mafuta otumizira kutentha amakhala ndi kukhuthala kwakukulu komanso kukana kwakukulu kotuluka m'malo ozizira.Pakatikati pa valve imatenga mtundu wotsegulira mwachangu, womwe ukhoza kuwongolera kuthamanga kwa kuthamanga ndikugonjetsa kukana koyenda bwino poyambira.Choncho, pofuna kuonetsetsa kukhazikika kwa kupanga, komanso kuti muchepetse mtengo weniweni wogwiritsira ntchito, makina opangira mafuta otenthetsera kutentha ayenera kusankha valavu yotsegula mwamsanga.valavu yosindikizira yosindikizira, sangasankhe valavu yosindikizira yosindikizira kapena vavu wamba.
Mavuvu osindikiza valavu yapadziko lonse lapansizopangidwa ndi BESTOP ndizoyenera kwambiri kudula mayendedwe a mapaipi amafuta otentha.
