Siab -Frequency Start-Stop Cycle Durability of Indirect Lead Heating Tubes rau Cov Khoom Siv Ntau Lawm
Cov khoom siv ua haujlwm tsis sib xws xws li cov tshuab ua cov tshuab ua haujlwm, cov khoom siv kom qhuav ib ntus thiab lub sijhawm cua sov pwm yuav tsum tau pib ntau zaus- nres cua sov txhua hnub. Cov kab hluav taws xob hluav taws xob ncaj qha hluav taws xob yog qhov ua rau cov hlau hauv paus qaug zog, sealing tawg thiab lub zog attenuation nyob rau hauv siab - zaus pib- nres cuam tshuam, ua rau lub neej luv luv. Indirect lead heating tubes txais cov qauv kev hloov pauv kev ntxhov siab tsis zoo los tiv thaiv lub voj voog thermal qaug zog, tswj kev ua haujlwm ruaj khov tom qab kaum tawm txhiab tus pib- nres lub voj voog thiab txhawb nqa ntev - lub sijhawm ua haujlwm tsis tu ncua ntawm thermocouple ntse lub voj voog tswj tshuab.
Siab -frequency start-stop cycle yog ib qho kev kuaj kev laus hnyav rau cov raj cua sov. Txhua qhov kev pib ua kom kub nce sai thiab thermal nthuav dav, thiab txhua qhov kev kaw yuav ua rau kom txias sai sai thiab kev cog lus. Cov hluav taws xob hluav taws xob ncaj qha hluav taws xob cua sov lub raj xaim cov hauv paus hniav yog cov ntsiab lus tsis muaj zog tshaj plaws, ua rau muaj kev rov qab thermal expansion thiab contraction stress. Ntev -lub sij hawm cyclic kev nyuaj siab ua rau hlau hlau qaug zog puas thiab sealing txheej tawg propagation. After thousands of cycles, invisible structural damage accumulates into permanent failure, leading to heating tube scrapping.
Cyclic qaug zog kev puas tsuaj coj kev ua tau zoo degradation. Feem ntau pib- nres cuam tshuam loosens cov rwb thaiv tsev sab hauv thiab tsim cov pa me me. Cov huab cua sib txawv tau nthuav dav dua nrog kev hloov pauv ntawm qhov kub thiab txias, ua rau txo qis kev ua haujlwm ntawm rwb thaiv tsev thiab tsis ruaj khov thaum tshav kub kub conduction. Cov hluav taws xob cua sov tso zis maj mam drifts, ua rau cov thermocouple lub voj voog tswj tsis tuaj yeem ua kom haum cov cua sov tiag tiag. Qhov kub sib txawv ntawm txhua batch ntau lawm, uas ua rau inconsistent batch khoom zoo.
Indirect lead cua sov tubes txhim kho cyclic qaug zog tiv thaiv los ntawm cov hlau tsis zoo hloov cov qauv. Tag nrho cov thermal expansion thiab contraction stress ntawm lub raj qhov hluav taws xob yog yug los ntawm siab - lub zog hlau hloov rods es tsis txhob ntawm fragile hlau hauv paus hniav. Cov qauv hlau muaj zog tiv thaiv- kev ua haujlwm qaug zog thiab tuaj yeem tiv taus ntau txhiab tus siab - zaus kub hloov pauv yam tsis muaj deformation thiab tawg tawm. Sab hauv cov cua sov hlau thiab rwb thaiv tsev txheej yog tsau los ntawm kev txwv compression technology, tsis txhob cyclic loosening thiab sib txawv tiam.
Welded integrated indirect lead qauv ntxiv txhim khu lub voj voog durability. Lub fusion vuam qauv tsim seamless hlau conduction kev koom ua ke, tsis muaj xoob kev sib cuag qhov khoob uas yooj yim rau qaug zog. Tag nrho cov kev tiv thaiv hluav taws xob tseem nyob ruaj khov nyob rau hauv ntev - lub sij hawm ua haujlwm cyclic, tsis muaj hluav taws xob drift thiab cua sov tso tawm attenuation. Lub sealing qauv tswj tsis tu ncua thiab compact lub xeev tom qab rov qab txias thiab kub mus.
Kev ua haujlwm ruaj khov ntawm cov cua kub cua sov ua kom ntev -lub sij hawm sib xws ntawm thermocouple cycle control logic. Qhov kub nce thiab lub caij nplooj zeeg cov cai ntawm txhua lub voj voog yog qhov rov ua tau zoo heev, ua rau lub tshuab thermocouple kaw lub voj voog ruaj khov yam tsis muaj kev rov ua dua tshiab. Cov txheej txheem batch ntau lawm tswj cov qauv ntsuas kub ruaj khov, txo cov khoom lag luam tsis zoo los ntawm kev ua haujlwm cua sov attenuation.
Rau cov khoom siv sib txuas ua ke, cov tshuab ziab khaub ncaws tsis tu ncua thiab nquag pib- nres pwm cua sov cov cuab yeej, cov kav hlau tsis ncaj ua rau cov cua sov ua kom daws tau qhov teeb meem ntawm kev qaug zog tsis ua haujlwm ntawm cov khoom cua sov ib txwm muaj. Kev koom tes nrog kev txawj ntse thermocouple lub voj voog tswj, lawv paub ntev - lub sij hawm ruaj khov thiab siab - tsis tu ncua kev lag luam cua sov ntau lawm.
