Mukamva 'chitsanzo', ambiri amaganiza kuti ndi tsamba la fan mu mpope kapena chosakanizira. Ndilo lingaliro lolakwika loyamba. M'malo mwake, geometry yake - mbali ya tsamba, kukulunga, m'lifupi mwake - imayang'anira chilichonse kuyambira pakuchita bwino kwadongosolo mpaka moyo wa msonkhano wonse. Ndawonapo ma projekiti ambiri pomwe chowongoleracho chinali chongoganizira, zomwe zimatsogolera ku phokoso la cavitation lomwe limamveka ngati miyala mu chitoliro kapena pampu yomwe imayenda mochulukira mkati mwa miyezi ingapo. Ndi mtima, osati chowonjezera.
Mdyerekezi Ali Pazowonetsera
Kukonzekera bwino kumayambira ndi nkhungu. Kwa ma impeller ovuta, makamaka otsekedwa kapena otseguka pang'ono okhala ndi zilolezo zolimba, kuponya ndalama nthawi zambiri ndiyo njira yokhayo yotheka. Ungwiro wa chitsanzo cha sera ndi chilichonse. Cholakwika chaching'ono mu kufa, kusagwirizana pang'ono, kumabwerezedwa muzojambula zilizonse. Ndimakumbukira gulu la mpope wamadzi am'madzi pomwe m'mphepete mwa masambawo anali okhuthala nthawi zonse kuposa momwe zimakhalira. Sizinalephere kuyang'ana pamiyeso, koma mawonekedwe a magwiridwe antchito anali pafupifupi 15%. Wolakwa? Kuchepa kwa sera sikunalipidwe mokwanira pamapangidwe ake. Limenelo ndi phunziro la mtengo wapatali lomwe laphunziridwa osati pa bolodi lojambula, koma pambuyo pa kutsanuliridwa mazana a zidutswa.
Apa ndi pamene zokumana nazo za foundry zikuwonetsa. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zawo zachipolopolo ndi kupanga ndalama, angapeze izi. Iwo mwina awona kuchepera konse ndi kupotoza zochitika m'buku. Kugwira ntchito ndi zitsulo zosapanga dzimbiri kapena ma aloyi opangidwa ndi faifi tambala pa ntchito zowononga kumawonjezera wosanjikiza wina; zitsulo zoyenda ndi kuzizira ndizosiyana. Simungathe kugwiritsa ntchito njira yachitsulo ya carbon. Kuchita kwawo kwanthawi yayitali kukuwonetsa kuti asintha njira zawo pazida, zomwe ndizofunikira.
Nthawi zina, vuto silikhala kuponya koma kuyeretsa. Malo otayira m'chigawo cha lilime la volute kapena kumbali yakukakamiza kwa tsamba amafunika kupukuta mosamala. Pogaya malo amodzi, ndipo mumasintha mawonekedwe a hydraulic. Ndaumirira kugwiritsa ntchito zilolezo zogayira zopangira ma impellers ovuta, zomwe masitolo ena amawona kuti ndizotopetsa. Koma ndi chimenecho kapena chiwopsezo cha kugwedezeka kwa harmonic pambuyo pake.
Machining: Kumene Chiphunzitso Chimakumana ndi Chuck
Ngakhale kuponyedwa kwangwiro kumafunikira makina olondola. Kubowola kwa shaft, nkhokwe ya hub, ndipo movutikira kwambiri, kusanja kosinthika. Apa ndipamene CNC imatsimikizira kufunika kwake. Mufunika makina oti azitha kuthana ndi kudula kosokonekera kwa masamba popanda macheza. Ndidagwira ntchito yolumikizira pawiri pomwe shopu yoyamba idayesa kuyika mabala amtundu wa 3-axis. Mapeto ake anali oopsa, ndipo kusanja kwake kunali kovutirapo—kunkafunika kuboola mopitirira muyeso.
Kukhazikitsa koyenera kwa ma multi-axis kuli bwino. Zimakuthandizani kuti muyandikire ma contours a tsamba mwachindunji. Tsatanetsatane waukadaulo pa https://www.tsingtaocnc.com Onetsani luso lawo la CNC, zomwe ndizomwe zimafunikira. Kwa chopopera chothamanga kwambiri, kalasi yoyenera (monga G2.5 kapena G1.0) imatchulidwa. Kukwaniritsa zimenezo sikungochepetsa thupi; ndi za kufanana koyamba kuchokera ku makina. Ngati CNC ntchito likulu ndi masamba ndi symmetric, ndi kuwongolera kuwongolera ndi kochepa ndipo sanyengerera structural umphumphu.
Nthawi ina tidapeza zopangira ma compressor mu aloyi yochokera ku cobalt. Machining anali chilombo. Zinthu zimagwira ntchito-zimalimba mwachangu. Sitoloyo idayenera kusintha ma feed, liwiro, ndi kugwiritsa ntchito zokutira zida zapakati pa ntchito. Izo sizinali ntchito yamabuku; zinali zosinthika nthawi zonse potengera mawonekedwe a zida. Sitolo yomwe imangokhala ndi zitsulo zofewa zikadawononga ziwalozo.
Kusankha Zinthu Zakuthupi Sikungokhudza Kuwonongeka Kokha
Aliyense amasankha 316 osapanga madzi am'nyanja. Ndi chiyambi chabwino. Koma pamapulogalamu othamanga kwambiri, monga pampu yolimbikitsira masitepe ambiri, mphamvu zakuthupi ndi kukana kutopa zimakhala zofunika kwambiri. Chitsulo chachitsulo chikhoza kukhala bwino pa 1800 rpm, koma pa 3600 rpm, kupanikizika kwapakati kumawirikiza kanayi. Ndipamene mumayang'ana duplex zosapanga dzimbiri kapena ma aloyi a nickel ngati Inconel 725.
Ndikukumbukira pulojekiti yobwezeretsanso momwe tidasinthira zoyika zitsulo zotayidwa ndikuyika chitsulo chapamwamba kwambiri pampope yamatope, poganiza kuti inali yamphamvu. Zinali choncho, koma zinali zolimba kwambiri. Zotsatira za tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono ta tsamba, zomwe zimachititsa kuti pakhale kulephera kwakukulu. Tinabwerera m'mbuyo ndi kugwiritsa ntchito martensitic zosapanga dzimbiri - zolimba, osati zolimba. Mtengo wa QSYKutchulidwa kogwira ntchito ndi ma aloyi apadera monga cobalt ndi nickel ndikofunikira apa. Zikutanthauza kuti amamvetsetsa zimango zomwe zimagwiritsidwa ntchito, osati chemistry.
Nthawi zina kusankha kolakwika kumakhudza kupulumutsa ndalama pazinthu zokha, koma kumanyalanyaza mtengo wake wonse. Choyikapo chitsulo chotsika mtengo cha kaboni m'malo a acidic pang'ono chikhoza kutha chaka. The downtime ndi ntchito m'malo ndalama kuwirikiza kakhumi kusiyana zinthu. Ndi mawerengedwe osavuta owerengera nthawi zambiri amaphonya.
Kuphatikiza ndi System Effect
Choyambitsa sichigwira ntchito chokha. Kuchita kwake kumalumikizidwa ndi chilolezo cha volute casing, kasinthidwe ka chitoliro choyamwa, komanso valavu yakumunsi. Kulakwitsa kwachikale ndikuyika chopondera chapamwamba kwambiri mu kabati yakale, yovunda ndikuwonjezera chilolezo chamkati. Kupindula kwa magwiridwe antchito ndikochepera chifukwa kutayika kobwerezabwereza kumawononga zabwino zonse.
Tinayesa izi kamodzi. Watsopano, wokometsedwa wochititsa m'chikwama chatsopano chagunda 82%. Cholowera chomwechi mubokosi lokhala ndi chilolezo cha mphete chokulirapo cha 0.5mm (chikadali m'malire ovomerezeka okonzanso) chatsika mpaka 78%. Ndilo malo enieni apadziko lonse lapansi omwe simudzawapeza pa pepala lodziwika. Zokwanira, makamaka zokhala ndi mphete zosinthika, ndimwambo wokonza womwe umanyalanyazidwa.
Nkhani ina yamakina ndi Net Positive Suction Head (NPSH). Choponyera chokongola komanso chopangidwa ndi makina chidzakhalabe cavitate ngati dongosolo la NPSHA ndilotsika kwambiri. Ndidayitanidwa kuti ndizindikire kulephera kwa ma impeller komwe masambawo adakokoloka, koma ndinapeza kuti vuto linali fyuluta yolowera kapena chingwe chocheperako chocheperako cha mita atatu kumtunda. Wosonkhezerayo anali wogwiriridwa, osati chifukwa.
Kulephera ngati Chida Chowunikira
Mumaphunzira zambiri kuchokera ku chisonkhezero cholephera kuposa changwiro. Chitsanzo chosweka chimafotokoza nkhani. Kutopa ming'alu kufalikira kuchokera muzu wa tsamba? Kugwedezeka kowoneka bwino kapena kuwonongeka kwakuthupi. Kukokoloka kwa yunifolomu kutsogolo? Cavitation. Kubowola kokhazikika pamasamba enaake? Kukhoza kukhala kupotoza koyenda kuchokera ku chigongono chapafupi. Ndimasunga zithunzi zolephera. Ndizinthu zophunzitsira zabwino kwambiri za gulu langa.
Chochitika chimodzi chosaiŵalika chinali choyikapo nyali chomwe chinameta pakhoma. Lingaliro loyambirira linali vuto lakuponya. Kusanthula kwazitsulo kunawonetsa zinthu zabwino. Kufufuza kwina kunatsata kugwedezeka kwapang'onopang'ono kochokera pamalumikizidwe olakwika omwe adapanga kumveka kozungulira ndendende pama frequency achilengedwe a choyikapo. Kukonzekera sikunali kopangidwa kwatsopano, koma kulumikizana kolimba komanso kuyanjanitsa kolondola kwa laser. Choyikapo nyalicho chinali canary mu mgodi wa malasha kwa nkhani yotakata yamakina.
Ichi ndichifukwa chake njira yonse yopangira zinthu imakhala yofunika. Woyambitsa ndi makina ngati Mtengo wa QSY yomwe imapereka ntchito zophatikizika kuchokera ku kuponyera kupita ku makina a CNC imapereka mwayi wosasinthika. Amalamulira zosintha zambiri. Ngati kulephera kukuchitika, kusanthula kwazomwe zimayambitsa kumakhala kosavuta - simukuchita ndi ogulitsa awiri omwe akuimba mlandu wina ndi mnzake. Kwa wogwiritsa ntchito kumapeto, kutsatiridwa kumeneko ndikofunika, ngakhale sikukhala kotchipa kwambiri nthawi zonse.
Malingaliro Omaliza: Ndi Ecosystem
Choncho, kulankhula za wochititsa sikuti ndi gawo limodzi chabe. Ndi za njira yoponyera yomwe imajambula cholinga chake cha hydraulic, makina omwe amazindikira kulondola kwake, zinthu zomwe zimapulumuka malo ake ogwirira ntchito, ndi kachitidwe kamene amakhalamo. Ndizopangidwa ndi zaluso ndi sayansi-zowonjezera zamphamvu zomangidwa pamakhota amalingaliro. Zabwino kwambiri zimachokera ku mgwirizano pakati pa injiniya wojambula yemwe amadziwa malo omwe ali ndi ntchito ndi wopanga yemwe amadziwa momwe zitsulo zimakhalira pamene mukuyesera kuzipanga. Mgwirizano umenewo, womwe unamangidwa kwa zaka zambiri komanso kubwerezabwereza kosawerengeka, ndizomwe zimasandutsa chojambula kukhala gawo lodalirika lozungulira. Sizokongola, koma pamene ziri zolondola, dongosolo lonse limangong'ung'udza.
