Cov ntaub ntawv dab tsi uas nquag siv hauv Tube Bundle Heat Exchangers?
Tube bundles yog ib feem tseem ceeb ntawm lub tshav kub exchanger. Tube bundle heat exchanger yog lub tshav kub exchanger uas hloov cov cua sov tshwm sim los ntawm lub raj ntim cov qauv.
Nyob rau hauv ib lub raj bundle heat exchanger, cua sov hloov feem ntau tshwm sim ntawm sab hauv thiab sab nraud ntawm cov hlab. Ib lub hnab ntim cov raj muaj cov raj sib txuas ua ke, uas feem ntau yog ua los ntawm cov hlau xws li tooj liab, stainless hlau lossis titanium. Cov xov xwm kub ntws los ntawm sab hauv ntawm cov raj, thaum cov kua dej kom sov los yog txias ntws los ntawm sab nraud ntawm lub raj ntim.
Cov khoom siv hauv lub raj ntim cov khoom siv hauv cov khoom siv hluav taws xob hauv lub raj xa hluav taws xob feem ntau nyob ntawm qhov xav tau ntawm daim ntawv thov thiab kev ua haujlwm. Cov hauv qab no yog qee yam khoom siv tube pob khoom:
Copper: Tooj yog ib qho zoo heev thermal conductive khoom nrog zoo tshav kub hloov zog thiab corrosion kuj. Nws yog feem ntau siv rau hauv cov ntawv thov kub thiab nruab nrab xws li cua txias tshuab, chillers thiab qee cov txheej txheem tshuaj.
Stainless hlau: Stainless hlau muaj zoo heev corrosion kuj, tshwj xeeb tshaj yog rau acidic thiab alkaline ib puag ncig. Nws yog feem ntau siv nyob rau hauv qhov kub thiab txias daim ntawv thov xws li petrochemical, zaub mov ua thiab nuclear fais fab nroj tsuag.
Titanium: Titanium muaj kev tiv thaiv zoo heev thiab tiv taus dej hiav txwv thiab ntau yam tshuaj lom neeg. Nws yog feem ntau siv hauv seawater desalination, tshuaj lom neeg kev lag luam thiab marine engineering thiab lwm yam kev lag luam.
Brass: Brass yog ib qho alloy ntawm tooj liab thiab zinc nrog zoo thermal conductivity thiab mechanical zog. Nws yog feem ntau siv rau hauv cov ntawv thov kub thiab nruab nrab xws li cov cua sov, cov tshuab ua dej huv huv thiab cov tshuab ua kom sov.
Nickel Alloys (Nickel Alloys): Nickel alloys muaj kev tiv thaiv corrosion zoo thiab lub zog kub thiab tsim nyog rau kev siv hauv qhov chaw kub thiab corrosive, xws li tshuaj lom neeg, roj av thiab roj refining.
Ntxiv nrog rau cov ntaub ntawv saum toj no, muaj lwm cov ntaub ntawv tshwj xeeb, xws li molybdenum, aluminium, steel thiab plastics, uas tuaj yeem siv rau hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob raws li cov kev xav tau tshwj xeeb. Thaum xaiv cov khoom siv hauv lub raj, cov khoom xws li corrosiveness ntawm qhov nruab nrab, qhov kub thiab txias, yuav tsum tau xav txog thiab kev lag luam.
