I-thermocouples yokushisa okuphezulu ayiphumeleli-kungekhona kwiingcingo eziphosakeleyo, kodwa ukusuka kwiibhubhu zokukhusela eziqhekekileyo, ezigqwesileyo, okanye ezingalunganga. Siyibonile kwiziko lentsimbi elifudumeza umlilo apho imijikelo ye-1200 ° C ikhukulisa imikhono ye-alumina phantsi kweenyanga ezintandathu. Siye satshintsha iityhubhu ze-cobalt-alloy kwimpompo ezininzi zaselwandle emva kokungena kwamanzi olwandle kugqwetheke ujongano lweflange. Ukuthembeka kwehlabathi lokwenyani kuqala ixesha elide ngaphambi kokuba inzwa ilinganiswe: iqala ngombhobho wokukhusela.
Kutheni "ifektri ye-tube yokukhusela i-Thermocouple" ayikho nje igama lokukhangela-yinto ecacileyo
Uninzi lwabathengi baphatha iityhubhu zokhuseleko njengehardware yegeneric. Akunjalo. Ityhubhu esebenza kwi-oveni yelebhu iyasilela ngokuyingozi kwimpompo yepiston ye-hydraulic yendlu evezwe kumothuko oshushu, ukungcangcazela, kunye neoyile egcweleyo. Umzi-mveliso ochanekileyo awugcini nje ukuphosa okanye umatshini we-cylinder. Yenza isithintelo-i-dimensionally stable kwi-1100 ° C, i-metallurgically ehambelana ne-thermocouple sheath, kwaye ifakwe ngomatshini ukuxhathisa ukudinwa kwi-flange ekhulayo.
Oko kufuna izakhono ezintathu ezingenakuxoxisana: okokuqala, ukulawulwa kwee-alloys eziphezulu ezifana ne-AMS 5387 cobalt-chromium kunye ne-T800-grade superalloys-izinto ezichasene ne-creep kodwa zifuna ulawulo oluchanekileyo lonyango lokushisa; okwesibini, ukudityaniswa okuthe nkqo kokuphosa utyalo-mali * kunye* ne-multi-axis CNC machining ukubamba ukunyamezela kwe-± 0.02 mm kwiindawo zokutywina ezibalulekileyo; okwesithathu, ukulandeleka okupheleleyo kwezinto-ukusuka kwiingxelo zovavanyo lokusila eziqinisekisiweyo ukuya kwiqashiso lobulukhuni obuthile kunye nokuqinisekiswa kwesakhiwo senkozo.
Iindlela ezine zokungaphumeleli-kunye nendlela umzi-mveliso ofanelekileyo othintela ngayo nganye
Silandelela ukusilela kwebala kuwo wonke amaziko ombane aseMntla Melika kunye neziza zepetrochemical zaseAsia. Oonobangela abane balawula:
- Ukuqhekeka okungafaniyo kweThermal: Xa ityhubhu ikhula ngokukhawuleza kune-thermocouple sheath okanye i-flange ekhulayo, i-microfractures yenza i-weld joints. Isisombululo: i-alloy pairing iqinisekiswe nge-coefficient-of-thermal-expansion (CTE) ehambelanayo-kungekhona nje ukuthotyelwa kwebakala.
- Ukhukuliseko lwe-interface: Ukuhamba kwe-turbulent okanye i-slurry e-abrasive cuts kwi-tip ye-tube, eveza i-junction. Isisombululo: incam yejiyometri eqinileyo (umzekelo, i-conical okanye i-hemispherical) eyenziwe ngomatshini *emva* yonyango lobushushu-hayi ukuphoswa ngaphakathi.
- Ukuthotywa kwetywina: Ilahleko yoxinzelelo lweGasket kubushushu obuphezulu ivumela inkqubo yemidiya ingene. Isisombululo: amagxa okutywina aguqulwe ngokuchanekileyo kunye nokugqiba komphezulu Ra ≤ 0.4 µm-ingqinwe ngeprofilometry ye-optical, hayi uhlolo olubonakalayo.
- Idimensional drift: Iityhubhu zoluswa okanye zijike ngexesha lenkonzo ende, itsala i-thermocouple iphume kubunzulu bayo bokuntywiliselwa okulinganiselweyo. Isisombululo: i-annealing yokunciphisa uxinzelelo kwi-ASTM A967, ilandelwa yi-CMM-based-post-heat-heat-cerification verification of straightness and concentricity.
Ezi ayizizo iinkxalabo zethiyori. Kungenxa yoko omnye umthengi watshintshela ababoneleli emva kweebhetshi ezintathu ezilandelelanayo ze-Inconel 600 iityhubhu zibonise i-0.15 mm isaphetha kwi-900 ° C-idlula i-ASME B31.1 i-piping spec nge-300%.
Yintoni eyahlula umthengisi kwi-factory tube yokukhusela i-thermocouple
Umthengisi uthumela iityhubhu. Umzi-mveliso unikezela ngesiqinisekiso somgangatho wenkqubo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., oko kuthetha ukuba uphononongo lobunjineli luqala ngomzobo wakho we-GD&T-hayi iPO yakho. Sifaka iflegi emngciphekweni kwangethuba: ubukhulu bodonga oluyi-1.5 mm bunokusinda kuxinzelelo lwe-static, kodwa uhlalutyo lokudinwa kokungcangcazela lubonisa i-resonance kwi-210 Hz kwindibano yakho yempompo. Siphakamisa uyilo lwe-2.0 mm olunyathelwe-ludongeni olunomatshini wendawo ukuze kugcinwe ubunzima-kuqinisekiswe yi-FEA ngaphambi kokusetyenziswa.
Indawo yabo ethobela i-ISO iphatha zombini izindlu ezisanti-santi zophando lweziko ezinobubanzi obukhulu kunye nemilomo yokuphoswa kotyalo-mali ukwenzela ukujonga umbhobho womoya. Yonke ibhetshi ye-cobalt-nickel yenziwa kuhlahlelo lwe-spectrographic, uvavanyo lwe-intergranular corrosion nganye nge-ASTM A262 Practice E, kunye nokuqinisekiswa kwe-tensile kwigumbi kunye nobushushu benkonzo. Akukho "mathiriyeli eqinisekisiweyo" ngaphandle kwembali yobushushu ebhaliweyo. Akukho kupasa okulinganayo ngaphandle kokulandeleka kweCMM ukuya kwimigangatho yeNIST.
Abafaki isitokhwe "eqhelekileyo" iityhubhu. Bagcina i-AMS 5387 billet, i-ingots ye-T800, kunye ne-316L engenasici-ke umatshini, i-cast, okanye i-hybrid-process nganye kwi-odolo yemfuneko yokusebenza, kungekhona inombolo yekhathalogu.
Ukukhetha iqabane lakho: imibuzo ebhentsisa isakhono
Buza oku ngaphambi kokuba ucele isicatshulwa-kwaye ujonge ukuba baphendula nzulu kangakanani:
- Ngaba unokubonelela ngegophe lokwandiswa kwe-thermal kwityhubhu yakho ye-AMS 5387 phakathi kwe-25 ° C kunye ne-1100 ° C-kwaye uqinisekise ukuba ilinganiswe kwinqanaba elifanayo elisetyenziswa kwimveliso?"
- "Sibonise iingxelo zakho ezintathu zokugqibela zeCMM ze-12 mm OD × 1.5 mm ityhubhu yodonga-ngokukodwa ukutenxa okujikelezayo kubude obuphakathi kunye nokuphuma kwengcebiso."
- "Uyiqinisekisa njani ingqibelelo yetywina emva komatshini wokugqibela? Uvavanyo loxinzelelo? Ukuvuza kweHelium? Idayi ingena ebusweni bokutywina?"
- "Ukuba isicelo sethu sifuna i-engile ye-taper yesiko ekupheleni kokufaka, ngaba uyasimatshini ngaphambili okanye unyango lwasemva kobushushu-kwaye sithini isiphelo sakho somgangatho ophezulu ofikelelekayo kwelo nqaku?"
Iimpendulo ezingacacanga zibonisa ukuthembela kwizindlu zomntu wesithathu okanye izikhewu ezingaphandle kweshelufu. Ngokuchanekileyo, iimpendulo ezixhaswe yidatha zithetha ukuba uthetha no Umzi-mveliso wetyhubhu yokukhusela i-thermocouple.
Ukuthembeka akwakhelwa kwinzwa. Yenziwe ngobunjineli kwityhubhu-kwaye ihanjiswa ngamaqabane aphatha yonke i-millimeter yobukhulu bodonga, idigri nganye yetaper, yonke imida yokuma kwengqolowa njengobuthunywa. Leyo yimeko abathengi abalindelekileyo. Nantso umgangatho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. idibana-yonke imihla, kuwo wonke amatyathanga obonelelo lwehlabathi, kwizicelo apho ukusilela kungeyondlela yokukhetha.
