Kev tsim cov txheej txheem ntawm cov khoom siv hluav taws xob rov qab los ntawm cov khoom siv hluav taws xob yog ib qho kev tsim vaj tsev sib koom ua ke nrog kev ua haujlwm siab, cov ntaub ntawv tshawb fawb, thiab cov qauv tsim thermodynamic. Nws lub hom phiaj tseem ceeb yog ua kom tau txais txiaj ntsig zoo, ruaj khov, thiab ntev - lub neej hluav taws xob hluav taws xob rov qab los ntawm kev ua haujlwm nyuaj xws li kub siab, corrosion, thiab siab. Tag nrho cov txheej txheem tsim khoom tuaj yeem muab faib ua tsib theem tseem ceeb: kev ua haujlwm tseem ceeb, plhaub thiab thav duab fabrication, raj bundles los ua ke thiab vuam, kev tshuaj xyuas zoo, thiab qhov chaw tiv thaiv - corrosion thiab txheej.
Core Thaum tshav kub kub Exchange Component Manufacturing: Lub Foundation rau Thaum tshav kub kub hloov Efficiency
Thaum tshav kub kub pauv Cheebtsam yog "lub plawv" ntawm cov khoom siv; lawv cov kev ua tau ncaj qha txiav txim siab tag nrho cov efficiency thiab durability.
Finned Tube Processing (Tshwj xeeb rau Flue Gas khib nyiab thaum tshav kub kub)
High - zoo seamless steel los yog stainless hlau raj yog siv los ua lub hauv paus raj. Hlau strips yog tsau rau saum npoo ntawm lub hauv paus raj siv high- zaus vuam los yog cov txheej txheem winding los tsim cov fins, ua rau kom qhov chaw sib pauv kub. High- zaus vuam ua tiav ib qho kev sib txuas ntawm cov fins thiab lub hauv paus raj, uas ua rau lub thermal kuj tsawg li tsawg dua los yog sib npaug rau 0.001㎡・℃/ W, kom ntseeg tau tias muaj kev kub ntxhov.
Cov ntaub ntawv uas muaj xws li:
ND steel: Haum rau nruab nrab - thiab qis - kub sulfur - muaj cov pa roj (tsawg dua lossis sib npaug li 400 degree)
316L stainless hlau: Resistant chloride ion corrosion, haum rau corrosive ib puag ncig xws li tshuaj nroj tsuag thiab dej hiav txwv.
Duplex stainless steel/nickel-based alloy: Used in ultra-high temperature (>800℃) lossis siab - cov xwm txheej siab, xws li khib nyiab incineration thiab metallurgical industries.
Phaj kub exchanger phaj sib sau (tsim rau cov kua khib nyiab thaum tshav kub kub):
Siv stainless hlau (304/316L) los yog titanium alloy daim hlau, tsim rau hauv corrugated daim hlau los ntawm cov txheej txheem stamping los txhim kho turbulence thiab txhim kho cua sov coefficient. Cov phaj yog kaw los ntawm vuam lossis gaskets, nrog lub siab tsis kam ntawm 1.0-2.5MPa.
Kev tsim cov yeeb nkab cua sov (tsim rau nruab nrab- thiab qis-kub khib nyiab):
Siv cov pa roj carbon steel-dej lub ntiajteb txawj nqus tshav kub yeeb nkab qauv, sab hauv evacuated thiab ntim nrog dej ua hauj lwm, siv evaporation -condensation theem hloov mus cuag ultra- thermal conductivity (kub hloov coefficient ze li ib tug txiav txim ntawm magnitude siab dua ib txwm hlau), haum rau kev khiav hauj lwm tej yam kev mob ntawm 50-400 degree.
Plhaub thiab Ncej Fabrication: Ua kom muaj zog thiab sealing
Cov ntawv hlau yog ua los ntawm Q345R carbon steel lossis stainless hlau, nrog rau cov thickness txiav txim siab raws li qhov tsim siab (feem ntau 0.1-0.6 MPa). Kev tsim yog tiav los ntawm laser txiav thiab phaj dov.
Lub longitudinal thiab circumferential seams ntawm lub plhaub yog welded siv tsis siv neeg submerged arc vuam los yog roj shielded vuam, siv ib tug multi-txheej, multi- dhau welding txheej txheem, thiab nyob rau hauv 100% ultrasonic kuaj kom tsis muaj qhov tsis xws luag xws li tsis tiav fusion thiab porosity.
Cov ntawv raj yog machined los ntawm forgings, nrog meej qhov drilled siv lub CNC milling tshuab (lub qhov taub 0.1-0.2 hli loj tshaj lub tshav kub exchangers raj) los xyuas kom meej qhov tseeb ntawm expansion pob qij txha los yog vuam.
Tube Bundle Assembly thiab Vuam: Ua kom muaj kev ruaj ntseg thiab tiv thaiv kev tawg
Lub tshuab finned tubes lossis cov raj xa hluav taws xob tau muab tso rau hauv daim ntawv raj, thiab hydraulic tube expander yog siv los ua kom tiav qhov kev sib koom ua ke, kom ntseeg tau tias muaj kev sib txuas ntawm cov raj thiab cov ntawv raj kom tiv thaiv kev tawm mus.
Rau siab - cov khoom siv hluav taws xob kub kub, baffles lossis daim phiaj qhia kuj yuav tsum tau ua kom zoo dua txoj hauv kev airflow thiab tsis txhob cuam tshuam hauv zos los yog hnav.
Phaj cua sov exchangers raug kaw nrog lub siab tsis sib xws ntawm 20-30 MPa siv cov ntsia hlau clamping kom paub tseeb tias cov pa tawm -dawb foob ntawm cov phaj.
Kev soj ntsuam nruj nruj: Kev tswj xyuas tseem ceeb ua ntej xa khoom xa tuaj
Txhua yam khoom siv yuav tsum xeem dhau ntau qhov kev xeem:
Hydraulic Pressure Test: Kev ntsuas siab yog khaws cia ntawm 1.5 npaug ntawm qhov tsim siab rau 30 feeb los kuaj xyuas cov dej xau hauv welds thiab cov pob qij txha nthuav dav.
Cua Tightness Test: Compressed cua yog qhia, thiab cov ntsiab lus weld raug kuaj nrog xab npum dej kom paub tseeb tias tsis muaj cua npuas tsim.
Kev Ntsuas Kev Ntsuas Kub Kub: Simulating cov kev ua haujlwm tiag tiag, kev hloov pauv hluav taws xob tau raug txheeb xyuas kom tau raws li cov qauv. Piv txwv li, cov cuab yeej siv hluav taws xob pov tseg yuav tsum muaj cov khoom siv hluav taws xob pov tseg kom zoo dua los yog sib npaug li 80%.
Corrosion Resistance Test: Cov cuab yeej siv nrog cov xov xwm corrosive tau dhau los kuaj cov ntsev ntsev nruab nrab (48 teev tsis muaj xeb).
