Service Life Attenuation Curve thiab Full -Cycle Performance Change Law of Single-End Heating Rods
Kev pabcuam lub neej ntawm kev lag luam ib zaug -kawg cua sov rods tsis ruaj tsis ua hauj lwm los ntawm lub xeev qub, tab sis ua raws li ib txwm ua kom qis qis qis. Los ntawm qhov pib ua haujlwm ruaj khov theem, nruab nrab- lub sij hawm kev ua tau zoo attenuation theem mus rau lub sij hawm tsis ua hauj lwm tshwm sim, cov pas nrig cua sov muaj kev hloov pauv hauv kev ua kom sov, qhov kub thiab txias, kev tiv thaiv hluav taws xob thiab hluav taws xob tso tawm. Cov pab pawg tsim khoom feem ntau hloov cov pas nrig cua sov tsuas yog tom qab ua tiav qhov hluav taws kub, uas ua rau cov khoom siv tam sim ntawd kaw thiab batch ntau lawm cuam tshuam. Kev paub txog tag nrho- txoj cai lij choj kev ua haujlwm ntawm lub voj voog tuaj yeem paub txog kev saib xyuas kev kwv yees, zam kev ua yuam kev tam sim ntawd, thiab tuav lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm pwm kub tswj tshuab.
Nyob rau theem pib ua haujlwm ruaj khov (0-3000 teev ua haujlwm), lub pas nrig cua sov ib leeg yog nyob rau hauv lub xeev ua haujlwm zoo tshaj plaws. Sab hauv insulating muab tub lim yog ntom thiab tsis sib xws, cov cua sov hlau tsis zoo yog qhov ruaj khov, qhov sib txawv ntawm cov pwm yog tus qauv, thiab qhov chaw ntawm tus pas nrig lub cev yog huv si thiab tsis muaj cov pa roj carbon deposition. Lub tshuab hluav taws xob hloov pauv hluav taws xob tseem nyob siab dua 97%, qhov kub nce ceev yog ceev thiab ruaj khov, pwm kub sib txawv me me, thiab cov rwb thaiv tsev tiv thaiv tau khaws cia ntawm qib siab. Nyob rau theem no, cov pas nrig cua sov yuav luag tsis muaj kev ua haujlwm attenuation, cov nyhuv cua sov ruaj khov thiab tsis muaj qhov tsis zoo, uas yog lub sijhawm ua haujlwm kub ntawm cov khoom siv.
Thaum ntxov attenuation theem (3000-6000 teev ua haujlwm), hloov pauv hloov pauv hloov pauv pib tshwm sim. After multiple cold and hot cycles, the internal high-density filler produces tiny loose gaps, and the heat conduction uniformity decreases slightly. Qhov saum npoo ntawm lub cev pas nrig accumulates nyias cov roj stains thiab micro-carbon deposits, uas me ntsis cuam tshuam cov cua sov dissipation. Qhov pom tseeb tshaj plaws yog tias pwm kub nce ceev qeeb me ntsis, thiab qhov kub tuav lub zog yuav tsum tau nce kom zoo. Nyob rau theem no, kev tshuaj xyuas tsis tu ncua thiab qhov sib txawv tuaj yeem cuam tshuam qhov txo qis thiab rov ua haujlwm feem ntau, uas yog nyob rau hauv lub voj voog kho tau.
Nyob rau hauv nruab nrab- lub sij hawm aging theem (6000-10000 teev ua hauj lwm), irreversible structural attenuation tshwm sim. Internal rwb thaiv tsev muab tub lim yog pom tseeb txheej thiab xoob, lub hauv paus cua sov conduction yog thaiv, thiab lub sab hauv cov cua kub tsub kom hnyav. Lub cua sov hlau ua rau me ntsis hlau qaug zog, tus nqi tiv thaiv drifts, thiab lub zog tso zis tsis ruaj khov. Qhov saum npoo carbon deposition txheej thickens, uas ua rau lub sij hawm lub zos overheating ntawm tus pas nrig lub cev. Cov pwm kub hloov pauv ntau ntxiv, cov khoom lag luam tawm los txo qis me ntsis, thiab cov rwb thaiv tsev kuj tseem poob qis. Nyob rau theem no, kev tu yooj yim tsis tuaj yeem rov qab ua haujlwm tau zoo, thiab yuav tsum tau kuaj xyuas thiab hloov kev ceeb toom ntxov.
Nyob rau theem tsis ua hauj lwm lig tshwm sim (ntau tshaj 10000 teev ua haujlwm), cov pas nrig cua sov nkag mus rau qhov siab - lub sijhawm ua tsis tiav. Cov qauv xoob sab hauv ua rau muaj kev kub ntxhov hnyav, qhov nruab nrab ntawm cov rwb thaiv tsev yog ze rau kev puas tsuaj, thiab cov xaim cua sov muaj cov micro- puas tsuaj zais cia. Cov txheej txheej carbon tuab ua rau ntev -lub sij hawm ib nrab qhuav hlawv, thiab tus pas nrig lub cev kub yog tsis muaj kev tswj. Cov cuab yeej muaj qhov kub thiab txias ntau dhau, cua sov tsis ruaj khov thiab qee zaus hluav taws xob to tripping. Yog tias tsis hloov lub sijhawm, tam sim no luv luv Circuit Court thiab burnout faults yuav tshwm sim txhua lub sijhawm, ua rau cov khoom kaw thiab pwm kev nyab xeeb.
Cov kev ua haujlwm sib txawv muaj qhov sib txawv kiag li attenuation ceev. High-kev vibration thiab siab- cov kab ntau lawm sib cuam tshuam muaj qhov ceev tshaj plaws attenuation ceev, thiab qhov nruab nrab- lub sij hawm aging theem yuav nkag mus rau hauv li 4000 teev. Kev huv huv thiab qis- kev ua haujlwm ua haujlwm tsis tu ncua ntawm kev vibration tau qeeb qeeb, thiab lub sijhawm ua haujlwm ruaj khov tuaj yeem txuas ntxiv mus rau ntau dua 8000 teev. Environmental pollution℃thiab installation qhov sib txawv qhov tseeb yog qhov tseem ceeb cuam tshuam rau qhov attenuation nkhaus txoj kab nqes.
Formulating hierarchical txij nkawm thiab hloov cov tswv yim raws li txoj cai attenuation yog lub hauv paus ntawm refined khoom tswj. Ua kev tu vaj tu tsev nyob rau theem qis qis, kev tshawb nrhiav tsis tu ncua nyob rau hauv nruab nrab- lub sij hawm aging, thiab yuam hloov nyob rau hauv lub sij hawm tsis ua hauj lwm. Qhov no tag nrho - hom kev tswj xyuas lub voj voog tuaj yeem zam qhov tsis raug kaw tam sim ntawd, ua kom cov kab ntau lawm ruaj khov, thiab ua kom lub neej ua haujlwm siab tshaj plaws thiab kev lag luam ntawm ib qho -kawg cua sov rods.
