High-temperature thermocouples inokundikana-kwete kubva kune dzakakanganisika waya, asi kubva kune yakatsemuka, corrod, kana misaligned kudzivirira machubhu. Takazviona musimbi yesimbi inodziyazve mavira umo 1200 ° C kutenderera kunobvisa maoko ealuminium mukati memwedzi mitanhatu. Takatsiva machubhu ecobalt-alloy pamapombi ekumahombekombe mushure mekunge mvura yegungwa yapinda yakanganisa chimiro cheflange. Kuvimbika kwechokwadi kwepasirese kunotanga nguva refu sensor isati yagadziriswa: inotanga nechubhu yekudzivirira.
Nei "Thermocouple kudzivirira chubhu fekitori" isiri izwi rekutsvaga chete-inotsanangurwa
Vazhinji vatengi vanobata machubhu ekudzivirira segeneric hardware. Havasi. Chubhu inoshanda muhovhoni yerabhoritari inotadza zvakanyanya muhydraulic piston pombi imba yakafumurwa nekuvhunduka kwemafuta, kuzunguzika, uye nemafuta akaremerwa. Fekitori yekurudyi haingokande kana muchina silinda. Iyo inogadzira chipingamupinyi-chakadzikama pa 1100 ° C, metallurgically inoenderana ne thermocouple sheath, uye inomisikidzwa kuti irambe kuneta painokwira flange.
Izvo zvinoda zvitatu zvisingagone kutaurirana: kutanga, kubata kwepamusoro-kushanda alloys seAMS 5387 cobalt-chromium uye T800-grade superalloys-zvinhu zvinopikisa zvinokambaira asi zvinoda kunyatsogadzirisa kupisa kupisa; chechipiri, vertical kubatanidzwa kwekudyara kukanda * uye * akawanda-axis CNC machining kubata ± 0.02 mm kushivirira pane yakakosha yekuisa chisimbiso nzvimbo; chechitatu, kuteedzera kuzere kwezvinhu-kubva kune yakasimbiswa chigayo bvunzo mishumo kune mijenya-chaiwo kuomarara uye kusimbiswa kwezviyo.
Nzira ina dzokukundikana—uye kuti fekitari yakakwaniriswa inodzivisa sei imwe neimwe
Isu tinoteedzera kutadza kwemunda munzvimbo dzese dzeNorth America magetsi uye maSoutheast Asia petrochemical nzvimbo. Zvikonzero zvina zvinotungamira:
- Thermal mismatch cracking: Kana iyo chubhu ikawedzera nekukurumidza kupfuura iyo thermocouple sheath kana inokwira flange, microfractures inoumba padyo ne weld majoini. Solution: alloy pairing yakasimbiswa kuburikidza nekoefficient-of-thermal-expansion (CTE) kufananidzwa-kwete kungotevedzera giredhi rezita.
- Interface erosion: Turbulent kuyerera kana abrasive slurry inocheka mukati mechubhu tip, ichifumura junction. Solution: yakaoma tip geometry (e.g., conical kana hemispherical) machined * after* heat treatment-kwete kuiswa-mukati.
- Chisimbiso kuderedzwa: Gasket compression kurasikirwa patembiricha yakakwira inoita kuti media media ipinde. Kugadzirisa: kunyatso-kutendeuka kuvhara mapepa nepamusoro pekupedzisira Ra ≤ 0.4 µm-yakasimbiswa ne optical profilometry, kwete kuongorora kwekuona.
- Dimensional drift: Machubhu anorebesa kana kuchinjika panguva yebasa renguva refu, achikwevera iyo thermocouple kubva mukudzika kwayo kunyudzwa. Solution: stress-relief annealing per ASTM A967, inoteverwa neCMM-based post-heat-treatment verification yekutwasuka uye concentricity.
Izvi hazvisi zvinonetsa zvekufungidzira. Ndosaka mumwe mutengi achichinja vatengesi mushure mezvikwata zvitatu zvakatevedzana zveInconel 600 machubhu airatidza 0.15 mm uta pa900 ° C-kupfuura yavo ASME B31.1 piping spec ne300%.
Chii chinoparadzanisa mutengesi kubva kune thermocouple kudzivirira chubhu fekitori
Mutengesi anotakura machubhu. Fekitori inopa system-level vimbiso. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., zvinoreva kuti ongororo yeinjiniya inotanga neGD&T yako yekudhirowa-kwete PO yako. Isu tinomira njodzi nguva ichiripo: 1.5 mm mukobvu wemadziro unogona kupona kudzvanywa, asi vibrational kuneta kuongororwa kunoratidza resonance pa210 Hz mumusangano wako wepombi. Isu tinopa dhizaini ye 2.0 mm yakatsikwa-madziro ine machining emunharaunda ekuchengetedza uremu-yakasimbiswa neFEA isati yashandiswa.
Nzvimbo yavo inoenderana neISO inobata dzimba dzese-jecha-kukanda mahombe-dhayamita echoto probes uye mari-yakakandwa nozzles ekutarisa kupera kweturbine. Yese batch yecobalt-nickel inoongororwa spectrographic, intergranular corrosion kuyedzwa paASTM A262 Dzidzira E, uye tensile yekuongorora mukamuri uye tembiricha yebasa. Hapana "yakasimbiswa zvinhu" isina nhoroondo yekupisa yakanyorwa. Hapana dimensional pass isina CMM traceability kune NIST zviyero.
Ivo havatore "standard" machubhu. Ivo vanochengetera AMS 5387 billet, T800 ingots, uye 316L isina tsvina-ipapo muchina, akakanda, kana hybrid-maitiro odha yega yega kune inoshanda zvinodiwa, kwete nhamba yekatalogi.
Kusarudza mumwe wako: mibvunzo inofumura kugona
Bvunza izvi usati wakumbira quote-uye tarisa kuti vanopindura zvakadii:
- "Unogona here kupa iyo yekudziya yekuwedzera curve yeAMS 5387 chubhu yako iri pakati pe25 ° C ne1100 ° C - uye ugosimbisa kuti yakayerwa pane imwecheteyo inoshandiswa mukugadzira?"
- "Tiratidze mishumo yako yekupedzisira yeCMM yegumi nemaviri OD × 1.5 mm chubhu yemadziro-kunyanya kutenderera kutenderera pakati pehurefu uye tip runout."
- "Unoona sei kutendeseka kwechisimbiso mushure mekugadzira kwekupedzisira? Kudzvanya bvunzo? Helium inodonha? Dhayi inopinda pachiso chakasimwa?"
- "Kana application yedu ichida tsika yetaper angle pamagumo ekuisa, unoigadzira pre- kana post-heat treatment - uye ndeipi yako yepamusoro inogoneka kupera pane icho chinhu?"
Mhinduro dzisina kujeka dzinoratidza kuvimba nevechitatu-bato rekukanda dzimba kana kunze-pasherufu dzisina chinhu. Chaizvo, mhinduro dzakatsigirwa nedata zvinoreva kuti uri kutaura na thermocouple kuchengetedza chubhu fekitori.
Kuvimbika hakuna kuvakwa mukati me sensor. Yakagadzirwa muchubhu-uye inounzwa nevadyidzani vanobata mamirimita ese emadziro ukobvu, ese dhigirii retaper, yega yega yezviyo muganhu wekutarisa sechinangwa-chakakosha. Ndizvo zvinotarisirwa nevatengi. Ndiyo yakajairwa QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inosangana-zuva nezuva, kuyambuka cheni dzepasirese, zvekushandisa uko kutadza kusiri sarudzo.
