Ubwino wa chithandizo cha cryogenic cha mavavu ndi momwe ntchito zamakampani zimakhalira

Ubwino wa cryogenic chithandizo cha mavavu ndi mmene ntchito mafakitale Kutsika kutentha cryogenic processing luso akhoza kwambiri kusintha moyo utumiki wa zipangizo ndi: mkulu-liwiro zitsulo, chida chitsulo, kufa chitsulo, electrode mkuwa, zipangizo ufa, aloyi wolimba, ceramic, etc. Zitsanzo za kugwiritsa ntchito mankhwala a cryogenic kuti atalikitse moyo wautumiki wa magawo ndi makampani ena aku America ndi mayunitsi ena aku China akuwonetsedwa mu Table 2 ndi Table 3, motsatana. Table 4 ikuwonetsa kuchulukana kofanana kwa kusintha kwa zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri pambuyo pa chithandizo cha cryogenic. Ikhoza kuonjezera kukana kuvutika; Wonjezerani mphamvu ndi kulimba; Kupititsa patsogolo kukana kwa dzimbiri, kukana kuvala; Wonjezerani kukana mphamvu; Kuwonjezeka kwa mphamvu ya kutopa... Kugwirizana kwapamwamba: Mfundo ya chithandizo cha ma valve cryogenic ndi ntchito yake m'makampani (2) Ubwino ndi ntchito ya mafakitale ya mankhwala a cryogenic 3.1 Ubwino waukulu wa chithandizo cha cryogenic Ikhoza kupititsa patsogolo kukana; Wonjezerani mphamvu ndi kulimba; Kupititsa patsogolo kukana kwa dzimbiri, kukana kuvala; Wonjezerani kukana mphamvu; Kupititsa patsogolo kutopa; Pambuyo pa chithandizo cha cryogenic, chikhoza kuonetsetsa kuti zinthu zomwe zimagwiritsidwa ntchito nthawi zonse zimakhala ndi makina abwino; Sichimayambitsa kukula kwa mawonekedwe; Itha kugwiritsidwa ntchito pazatsopano / zogwiritsidwa ntchito; Angathe kuthetsa nkhawa mkati; Kupititsa patsogolo kukhazikika kwazinthu; The processing mtengo ndi otsika, chifukwa kutalikitsa moyo chida akhoza kuchepetsa nthawi ya kusintha chida ndi akupera, kuti apulumutse mtengo kupanga; Itha kukwaniritsa zotsatira zofanana ndi mankhwala ena apamwamba (monga Chin plating, chrome, Teflon); Mamolekyu olimba amatha kupangidwa, kuchepetsa mikangano, kutentha ndi kuvala pamalo okulirapo. 3.2 The workpiece waukulu kuti akhoza kukonzedwa ndi cryogenic chithandizo Kudula chida; Zigawo za injini zoyaka mkati; * * * chubu; Dinani; Kutumiza shaft; Zida zamankhwala; Pang'ono; The crankshaft.

Table 4 ikuwonetsa kuchulukana kofanana kwa kusintha kwa zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri pambuyo pa chithandizo cha cryogenic. Monga momwe tikuonera pa matebulo atatu otsatirawa, chithandizo cha cryogenic chimapanga zotsatira zosiyana pazigawo ndi zida za zipangizo zosiyanasiyana, ndipo kukana kuvala kwa ziwalo ndi zida kumakula kwambiri. 3.3.2 Kupititsa patsogolo kukhazikika kwa zipangizo Kupititsa patsogolo kukhazikika kwa zipangizo ndi ntchito ina yopambana ya chithandizo cha cryogenic mu aluminiyamu, mkuwa, Chin ndi 300 mndandanda wazitsulo zosapanga dzimbiri, makamaka aluminium ndi ma alloys ake. 3.3.3 Kupititsa patsogolo zinthu zakuthupi Chithandizo cha Cryogenic chikhoza kupititsa patsogolo ndi kupititsa patsogolo zinthu zakuthupi, monga mphamvu, kukana kutopa, kukana dzimbiri, ndi zina zotero. Gulu 5 limasonyeza zotsatira za m'munda zomwe zimachokera ku ntchito ya kafukufuku wa yunivesite ndi kafukufuku wa mafakitale pakupanga mafakitale. Ndi chitukuko cha makampani amakono, zofunika katundu katundu ndi apamwamba ndi apamwamba. Pali zinthu ziwiri zazikulu pakufufuza kwazinthu zamakono: ① Pangani umisiri watsopano nthawi zonse, njira zatsopano ndi zida zatsopano zopangira zida zatsopano zosiyanasiyana zokhala ndi zofunikira zapadera kapena zinthu zabwino kwambiri, monga kulimba mwachangu, kuphatikizika kwamakina, kuyika ndege, kuumba jekeseni ndi zina. njira zopangira microcrystalline, amorphous, quasicrystal, nanocrystalline structural and functional materials. ② Pazinthu zomwe zilipo kale monga chitsulo ndi chitsulo, aluminiyamu, mkuwa pogwiritsa ntchito kuyeretsa kopitilira muyeso, kuyeretsa kwakukulu, kupukuta, kupukuta ndi ukadaulo wina wapadera wokonza ndi kukonza, m'malo mwake sizisintha kapangidwe kazinthu zomwe zilipo pamaziko a imathandizira kwambiri magwiridwe antchito ake, kuti ipititse patsogolo kugwiritsa ntchito bwino komanso kubwezeretsanso zinthu. Panthawi imodzimodziyo, zinthu zakuthupi zimatha kusinthidwa, ndipo mtengowo ukhoza kuchepetsedwa kuti uchepetse kuwonongeka kwa chilengedwe, zomwe mosakayikira zimapereka njira yabwino yothetsera mavuto omwe akuwonjezereka kwambiri a mphamvu ndi chilengedwe. Choncho maphunziro a zipangizo cryogenic mankhwala adzakhala yofunika kafukufuku malangizo a chuma ogwira ntchito sayansi kunyumba ndi kunja, koma kukhazikika kwa kafukufuku alipo onse mu cryogenic mankhwala ndondomeko ndi limagwirira ntchito ya zinthu zina kafukufuku akadali zolakwa zambiri, chifukwa lalikulu ndi ntchito mankhwala cryogenic pa mafakitale anabweretsa zopinga, Choncho, chitukuko ndi kafukufuku khola dongosolo cryogenic ndondomeko ndi cryogenic mankhwala limagwirira a zitsulo sanali ferrous adzakhala cholinga cha kafukufuku m'munda uno.
