Khoma la Membrane, lomwe limadziwikanso kuti khoma loziziritsidwa ndi madzi, limagwiritsa ntchito machubu ndi zitsulo zosalala zowotcherera kuti zipange chinsalu cha chubu, ndiyeno magulu angapo a zowonera zamachubu amaphatikizidwa kuti apange khoma la membrane.
Ubwino wa kapangidwe ka khoma la membrane ndi chiyani?
Khoma loziziritsidwa ndi madzi limapangitsa kuti ng'anjoyo ikhale yabwino. Kwa ma boilers oponderezedwa, amatha kuchepetsa kwambiri kutayikira kwa mpweya wa ng'anjo, kukonza kuyaka mung'anjo, ndikuwonjezera malo otenthetsera ma radiation, motero kupulumutsa chitsulo. Makoma a membrane amagwiritsidwa ntchito kwambiri mu membrane khoma ma jenereta a nthunzi. Iwo ali ndi ubwino wa dongosolo losavuta, kupulumutsa chitsulo, kusungunula bwino komanso kupuma kwa mpweya.
The nembanemba khoma chubu chophimba kusungunula kwambiri yogwira mpweya wotetezedwa basi kuwotcherera kupanga mzere ndi zapamwamba kwambiri padziko lonse lapansi nembanemba khoma chubu chophimba kupanga teknoloji ndi zipangizo, kuyambira chubu Kutsegula, lathyathyathya zitsulo uncoiling, kumaliza, kusanja, kwa kuwotcherera, etc. Mfuti zowotcherera cham'mwamba ndi m'munsi zimatha kuwotcherera nthawi yomweyo, kuwotcherera kwazing'ono, ndipo palibe chifukwa chowongolera pambuyo pakuwotcherera, kuti miyeso ya geometric ya gulu la chubu ikhale yolondola, mtundu wa weld fillet ndi wabwino kwambiri, mawonekedwe ndi okongola, liwiro kuwotcherera ndi mofulumira, ndi dzuwa kupanga ndi mkulu.
Jenereta ya Nobeth steam imakhala ndi mzere wapamwamba wopanga khoma, ndipo ng'anjoyo imagwiritsa ntchito ukadaulo wosindikiza pakhoma wamadzi. Pokonza khoma la membrane, kuwotcherera mbali ziwiri kumagwiritsidwa ntchito, kotero kuti chogwiriracho chimatenthedwa kwambiri ndipo gulu la chubu silikhala lopunduka; imathetsanso kufunika kotembenuzira kuwotcherera, kuchepetsa ntchito yokonza mapindikidwe pambuyo kuwotcherera kwa chinthucho, ndikuwongolera kwambiri kupanga bwino. Chifukwa chake, ma jenereta ambiri a membrane amatumizidwa atasonkhanitsidwa kuchokera ku fakitale, zomwe zimapangitsa kuti mayendedwe ndi kuyika zikhale zosavuta, komanso kuchuluka kwa kukhazikitsa komwe kumafunikira ndi wogwiritsa ntchito kumachepetsedwa kwambiri.
(1) Khoma loziziritsidwa ndi madzi lili ndi chitetezo chokwanira kwambiri pakhoma la ng'anjo. Choncho, khoma la ng'anjoyo limangofunika zipangizo zotetezera m'malo mwa zipangizo zotsutsa, zomwe zimachepetsa kwambiri makulidwe ndi kulemera kwa khoma la ng'anjo, zimachepetsa kapangidwe ka khoma la ng'anjo, komanso kuchepetsa mtengo wa khoma la ng'anjo. Kulemera konse kwa boiler.
(2) Khoma loziziritsidwa ndi madzi limakhalanso ndi mpweya wabwino, limatha kutengera zomwe zimafunikira pakuwotcha kwabwino pa boiler, silimakonda kugwa, limataya mpweya pang'ono, limachepetsa kutayika kwa kutentha, komanso limathandizira kutenthetsa kwamafuta. boiler.
(3) Zidazi zimatha kuwotcherera ndi wopanga asanachoke kufakitale, ndipo kuyikako kumakhala kofulumira komanso kosavuta.
(4) Ma boilers omwe amagwiritsa ntchito khoma la membrane ndi osavuta komanso osavuta kusamalira, ndipo moyo wautumiki wa boiler ukhoza kusintha kwambiri.
Kuwotcherera kwa ma welds a pipe panel fillet
Tube chophimba kuwotcherera njira ya nembanemba khoma kuwala chitoliro ndi lathyathyathya zitsulo kapangidwe. Njira kuwotcherera ntchito nembanemba khoma kuwala chitoliro ndi lathyathyathya zitsulo dongosolo makamaka zikuphatikizapo zotsatirazi:
1. Makinawa kusungunuka kwambiri yogwira mpweya kutetezedwa kuwotcherera
Kuphatikizika kwa mpweya woteteza ndi (Ar) 85% ~ 90% + (CO2) 15% ~ 10%. Mu zipangizo, chitoliro ndi zitsulo zosalala zimapanikizidwa ndi odzigudubuza apamwamba ndi otsika ndikutumizidwa patsogolo. Mfuti zowotcherera zingapo zitha kugwiritsidwa ntchito kusunthira mmwamba ndi pansi. Kuwotcherera kumachitidwa nthawi imodzi.
2. Waya wabwino wolowetsedwa ndi kuwotcherera arc
Chida ichi ndi chokhazikika chimango kuwotcherera workstation. Chida makina ali ndi ntchito za chitsulo chitoliro ndi lathyathyathya zitsulo udindo, clamping, kudyetsa, kuwotcherera ndi basi kuthawa kuchira. Nthawi zambiri amakhala ndi mfuti 4 kapena 8 zowotcherera kuti amalize malo 4 kapena 8 opingasa nthawi imodzi. Kuwotcherera kwa fillet welds. Ukadaulo uwu ndi wosavuta kugwiritsa ntchito ndipo ulibe zofunikira zapamwamba pamtunda wa chitoliro ndi chitsulo chathyathyathya. Komabe, imatha kuwotcherera mbali imodzi pamalo opingasa ndipo sangathe kukwaniritsa kuwotcherera munthawi imodzi kumtunda ndi pansi.
3. Semi-automatic mpweya zitsulo arc kuwotcherera
Mukawotcherera ndi njira iyi, gulu la chubu liyenera kulumikizidwa ndi kukhazikitsidwa koyamba, kenako kuwotcherera ndi mfuti yowotcherera pamanja. Njira yowotcherera iyi sangathe kuwotcherera kumtunda ndi m'munsi panthawi imodzi, ndipo n'zovuta kukwaniritsa kuwotcherera kosalekeza ndi yunifolomu ya mfuti zowotcherera zingapo, choncho n'zovuta kulamulira kuwotcherera mapindikidwe. Pamene theka-automatic mpweya zitsulo arc kuwotcherera chitoliro kuwotcherera chitoliro, chidwi ayenera kuperekedwa kusankha wololera wa ndondomeko kuwotcherera kuchepetsa kuwotcherera mapindikidwe. Zowotcherera za fillet zomata zitsulo zathyathyathya pamitseko yam'deralo pa mapanelo a chubu, komanso zowotcherera za fillet za mapanelo ooneka ngati machubu apadera monga ma hopper ozizira aphulusa ndi ma nozzles oyaka, nthawi zambiri amawotcherera ndi kuwotcherera kwachitsulo chodziwikiratu.
The nembanemba khoma chubu chophimba kusungunula kwambiri yogwira mpweya wotetezedwa basi kuwotcherera kupanga mzere ndi zapamwamba kwambiri padziko lonse lapansi nembanemba khoma chubu chophimba kupanga teknoloji ndi zipangizo, kuyambira chubu Kutsegula, lathyathyathya zitsulo uncoiling, kumaliza, kusanja, kwa kuwotcherera, etc. Mfuti zowotcherera cham'mwamba ndi m'munsi zimatha kuwotcherera nthawi yomweyo, kuwotcherera kwazing'ono, ndipo palibe chifukwa chowongolera pambuyo pakuwotcherera, kuti miyeso ya geometric ya gulu la chubu ikhale yolondola, mtundu wa weld fillet ndi wabwino kwambiri, mawonekedwe ndi okongola, liwiro kuwotcherera ndi mofulumira, ndi dzuwa kupanga ndi mkulu.
