Mukuwona zokamba zambiri zokhuza mphamvu ya mpope, kapangidwe kake, magiredi azinthu. Chophimba? Nthawi zambiri amatengedwa ngati nyumba yosayankhula, yongoganizira. Kumeneko ndi kulakwitsa kwakukulu. Kwenikweni, a pompa pompa ndi chotengera chokakamiza chomwe chili ndi chilichonse, chimalamula njira zoyendetsera, chimayendetsa nkhanza, ndipo nthawi zambiri chimalamula ndandanda yokonza. Pezani zolakwika, ndipo chowongolera chabwino kwambiri padziko lapansi sichingakupulumutseni.
Lingaliro Lolakwika Lachikulu: Ndi Kungoponya Basi
Pamene mainjiniya amatchula a pompa pompa, chojambulacho chimatuluka ndi zolemba zakuthupi ndi kulolerana. Lingaliro ndilakuti maziko amawathira, malo ogulitsa makina amamaliza, ndipo amangiriridwa. Zowona ndi zonyansa. Kusankha pakati pa static cast ndi kuponya nkhungu, mwachitsanzo, sikungotsala pang'ono kumaliza. Ndi za umphumphu wamkati. Kuponyedwa kopanda zipata kungathe kusiya zotsalira zapakhosi pakhosi la volute. Simudzaziwona pa lipoti loyendera, koma mudzazimva ngati kugwedezeka kosalekeza pazigawo zina zogwirira ntchito, vuto lomwe limatsutsidwa ndi rotordynamics kwa miyezi.
Ndinaphunzira izi movutirapo pa ntchito ya mpope ya madzi ya boiler zaka zapitazo. Ma casingswo adanenedwa mu chitsulo chosapanga dzimbiri cha duplex chokana dzimbiri. Choyambira chimaperekedwa kuti chisindikizidwe, chowoneka bwino. Koma panthawi yoyesa madzi, tinalira kuchokera kugawo lowoneka ngati lolimba. NDT idapeza gulu la shrinkage, osati lalikulu mokwanira kulephera kuyesa, koma njira yotsimikizirika yolephera pansi pa njinga yamoto. Chifukwa chake? Mapangidwe a malo odyetserako chakudya ndi kukwera aloyi ndi makulidwe a khoma anali osakwanira. Zinali zabwino ndi CF8M wamba, koma duplex adachita mosiyana pakukhazikika. Ndilo lingaliro lomwe mumangopeza kuchokera kwa ogulitsa omwe amamvetsetsa zitsulo monga gawo la ntchito yoponya, osati ngati bokosi loyang'ana lapadera.
Apa ndipamene kuya kwa kampani kumawonetsa. Ndawunikanso ogulitsa ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd.. Kuganizira kwawo kwa nthawi yayitali chipolopolo nkhungu kuponyera ndi kuyika ndalama pazigawo zolondola, makamaka muzitsulo zapadera, zikuwonetsa kuti mwina alimbana ndi zovuta zolimba izi pama projekiti ambiri. Kwa otsutsa pompa pompa mu aloyi ya faifi tambala pa ntchito yotentha kwambiri, zomwe mwakumana nazo ndizomwe mukugula, osati kulolerana kwa makina.
Machining: Kumene Chiphunzitso Chimakumana ndi Thupi
Ngakhale ndi kuponyedwa kwangwiro, gawo la makina likhoza kuwonetsa zolephera zake. Cholakwika chapamwamba ndikuchitenga chosungirako ngati chosavuta chogwirira ntchito chomwe chiyenera kumangidwa patebulo la CNC. Chophimbacho sichiri cholimba; ndi geometry yovuta, yokhala ndi mipanda yopyapyala. Kuyika kolakwika kapena kudula mwamphamvu kumatha kumasula kupsinjika komwe kumapangitsa kuti gawolo lisunthe pambuyo pa opareshoni yoyamba. Mutha kukhala ndi nkhope za flange zomwe sizimazungulira kapena mabowo amabowo omwe amasuntha.
Kutsatira kumafunika kwambiri. Kodi mumasokoneza mbiri ya volute musanayambe kapena mutamaliza kusindikiza ndikusindikiza nkhope? Pali kutsutsana. Ena amakina amakonda kukhazikitsa mawonekedwe a datum poyamba kuchokera kugawo la as-cast. Ena amatsutsa kuti achotse kuchuluka kwa zinthu za volute kuti achepetse kupsinjika, kenako kukonzanso makina omaliza. Ndaziwona zonse zikugwira ntchito ndipo zonse zikulephera, kutengera kukula kwa casing ndi geometry. Sitolo yomwe imapanganso kupanga, monga QSY ndi zophatikizika CNC makina luso, lili ndi phindu lalikulu. Atha kukonzekera dongosolo lonse kuyambira pagawo lachitsanzo, kudziwa momwe gawolo lidzagwiritsidwire ntchito ndikudulidwa, mwinanso kupanga zikwama zoponya zomwe zimawirikiza ngati makina opangira makina.
Ndiye pali kutopetsa kwa tsinde ndi zipinda zosindikizira. Izi zikuwoneka zowongoka, koma kukhazikika komanso kutsirizika kwapamwamba apa ndizo zonse za moyo wa chisindikizo. Chizindikiro chomwe simungachimve ndi chikhadabo chidzawononga chisindikizo chomakina pakatha milungu ingapo. Katswiri wamakina wabwino amamva njira yoyenera ya zida, chakudya, ndi kugwiritsa ntchito koziziritsa pazida zosiyanasiyana—chitsulo choponyedwa, 316 chosapanga dzimbiri, kapena gummy duplex. Si pulogalamu chabe.
The Material Maze: Kupitilira Chitsulo Chosapanga dzimbiri
Kutchula chitsulo chosapanga dzimbiri cha a pompa pompa zilibe tanthauzo. Kodi ndi austenitic wamba ngati 304/316? Martensitic ngati CA15 yokana kukokoloka? A super duplex ngati 2507 kwa madera a chloride? Kapena alloy-based alloy ngati Inconel 625 chifukwa cha kutentha kwambiri ndi dzimbiri? Aliyense amachita moyipa mosiyanasiyana panthawi yoponya, makina, komanso muutumiki.
Ndikukumbukira ntchito ya mpope yoziziritsira madzi a m'nyanja pomwe zoyambira zinali 316L. Zikadayenera kugwira ntchito. Koma m'madzi enieni a m'mphepete mwa mtsinjewo, wokhala ndi ma chloride ochuluka komanso zochitika zamoyo zokhala ndi tizilombo toyambitsa matenda, tinakhala ndi zibowo komanso dzimbiri pankhope za gasket mkati mwa chaka. Kukonzekerako kunali kusintha kwapamwamba kwambiri duplex. Nsomba? Super duplex imadziwika kuti ndi yachinyengo kuponya ndikutenthetsa bwino kuti isungike bwino. Mukufunikira malo osungira omwe amatha kuwongolera bwino kuzizira komanso kutsekereza njira. Ngati aziphonya, mumapeza mpweya wa sigma, zomwe zimapangitsa kuti zinthuzo zisawonongeke. Wothandizira wodziwa ndi ma aloyi apadera, monga tafotokozera mu mbiri ya QSY, mwachibadwa amakhala ndi ndondomeko za izi. Amadziwa ma chart a kutentha kwa zinthu izi pamtima.
Pazinthu zomwe sizingawonongeko pang'ono koma zowononga - ganizirani kuphatikizika kapena phulusa - chitsulo choponyedwa chokhala ndi nickel-chrome choyang'ana molimba m'malo enaake chingakhale chisankho chanzeru. Chisankhocho sichimangokhudza madzi; ndi za mtengo wokwanira wa umwini, kuyeza mtengo wazinthu zoyambilira motsutsana ndi nthawi yomwe timayembekeza kuvala komanso kutsika kwa nthawi yosamalira.
Kuphatikiza & The Real-World Test
Umboni womaliza wa a pompa pompa ali pa skid, pansi pa kupsyinjika. Apa ndi pamene nkhani zonse zobisika zimawonekera. Kumutu kumodzi kosalekeza ndi kukhala pansi kwa gasket. Flange flatness pa chojambula ndi chinthu chimodzi; kukwaniritsa kalirole-womaliza, wopanda mafunde pamwamba pa lalikulu, mosasinthasintha kuponya flange pambuyo Machining ndi china. Ndakhala masiku ndi utoto wa buluu komanso zomata zokhala m'manja zazikulu zomwe zidatsikira pachiyeso choyamba cha hydro-chifukwa cha korona pang'ono pakati pa nkhope ya flange. Masiku ano CNC mphero iyenera kuthetsa izi, koma kupotoza kwa zida pamtunda wautali kapena kupsinjika kotsalira kumatha kuyambitsa.
Chinthu china chowawa chophatikizana ndi choyenerera ndi ziwalo zobvala zamkati. Kusiyanitsa pakati pa mphete yovala casing ndi mphete yovala impeller ndikofunikira. Ngati chotengeracho chikusokonekera ngakhale pang'ono mutapanganso (kachiwiri, kuchepetsa nkhawa), kapena ngati chosungiracho sichikuthandizidwa bwino chikakhomeredwa pansi, chilolezocho chitha kutha, kupha mphamvu. Nthawi zina mumayenera kunyamula pomaliza paketi yomwe ili pamwamba pake, sitepe yovuta koma yofunikira pamapampu akulu, okhala ndi mphamvu zambiri.
Chizindikiro chodziwika bwino cha casing yabwino? Momwe zimakhalira panthawi yovula pambuyo pa zaka za utumiki. Wowoneka bwino adzawonetsa ngakhale kuvala mu volute. Wosauka adzakhala ndi njira zosiyana za kukokoloka, maenje a cavitation m'malo enaake, kapena ming'alu yochokera ku kupsyinjika kwa ngodya zakuthwa zamkati - ngodya zomwe zimayenera kukhala ndi fillet koma mwina sizinali chifukwa cha kupanga mapangidwe kapena kulephera kwakukulu kwa msonkhano.
Kutsiliza: Msana Wosaoneka
Choncho, ayi pompa pompa si chipolopolo chabe. Ndilo malire amphamvu oyambira, kalozera wamayendedwe, ndipo nthawi zambiri zimalepheretsa kudalirika. Ubwino wake ndi ntchito yachindunji ya ukadaulo wophatikizika kwambiri-muzitsulo, kupanga mapangidwe opangira, makina ozindikira kupsinjika, komanso chidziwitso chamsonkhano. Simungayang'ane ndi mndandanda wosavuta. Pamafunika bwenzi lothandizira lomwe luso lake limayenda ulendo wonse kuchokera kuzitsulo zosungunula mpaka kukwanira komaliza, mtundu wa kuphatikiza koyima komwe makampani amakhala ndi zaka zambiri kupopera ndi makina kukula mwachibadwa. Kusiyana sikumawonekera pa dongosolo logulira; zimawonekera pakapita nthawi pakati pa zolephera patsamba, yomwe ndi metric yokha yomwe ili yofunika kwambiri.
