Txoj kev siv ntau tshaj plaws nyob rau hauv kev lag luam yog siv cov high-frequency inductance generated los ntawm high-frequency generator rau ib nrab yaj ntawm ib tug kub kub ntawm qhov sib cuag ntawm lub nto ntawm lub raj thiab lub fin, thiab ces txuas lub fin nrog lub raj. los ntawm pressurization.
Kuj tseem muaj kev siv lub tes tsho ncaj nraim rau ntawm cov yeeb nkab cua sov, los yog brazing thiab lwm yam, los yog siv txoj kev galvanizing.
Ib txheej ntawm fins
Cov txheej txheem txheej txheem yog ua tiav ib pawg ntawm cov fins ua ntej nrog lub tshuab xuas nrig ntaus, thiab tom qab ntawd siv phau ntawv lossis cov txheej txheem los teeb tsa cov fins rau sab nrauv ntawm lub raj los ntawm qhov siab ntawm qhov siab (tis pitch) los ntawm kev cuam tshuam. Nws yog ib qho ntawm cov txheej txheem ntxov tshaj plaws siv los ua cov raj finned. Vim tias txheej txheem txheej txheem yooj yim, cov txheej txheem kev xav tau tsis siab, cov cuab yeej siv yog pheej yig, thiab nws yooj yim los tswj, yog li ntau lub Hoobkas tseem siv nws. Cov txheej txheem no yog cov txheej txheem ua haujlwm hnyav, tsim nyog rau cov nyiaj txiag thiab kev ua haujlwm ntawm cov chaw tsim khoom me me lossis cov lag luam hauv nroog.
Cov txheej txheem dag yog hu ua phau ntawv teev. Nws yog nrog kev pab ntawm cov cuab yeej, tso siab rau lub zog ntawm tib neeg los tsoo cov fins ib qho los ntawm ib qho. Txoj kev no tsuas yog txwv vim tias lub zog nias ntawm cov fins tsuas yog txwv, yog li qhov cuam tshuam ntawm cov teeb yog me me, thiab cov fins yooj yim rau loosen. Mechanical teeb fins yog nqa tawm ntawm lub tshuab fin. Txij li thaum lub fin siab yog raws li cov neeg kho tshuab cuam tshuam lub zog los yog kua siab, lub zog nias yog qhov loj, yog li siv cov kev cuam tshuam loj dua. Kev sib txuas ntawm cov fins thiab lub raj yog muaj zog thiab tsis yooj yim rau loosen. Lub tshuab teeb tsa nrog cov neeg kho tshuab kis tau tus mob siab, tab sis lub suab nrov yog loj, kev nyab xeeb tsis zoo, thiab kev ua haujlwm ntawm cov neeg ua haujlwm tsis zoo. Txawm hais tias cov teeb meem saum toj no tsis muaj nyob rau hauv hydraulic kis tau tus mob, cov cuab yeej siv kim dua, cov kev cai rau kev siv cov neeg ua haujlwm tu siab dua, thiab nws cov khoom tsim tau qis dua.
B inlaid kauv fins
Inlaid kauv fin tube yog ib qho kauv zawj ntawm qee qhov dav thiab qhov tob ua ntej ua ntej ntawm cov yeeb nkab steel, thiab tom qab ntawd cov hlua hlau yog kos rau ntawm cov yeeb nkab steel ntawm lub tshuab dhos. Nyob rau hauv cov txheej txheem winding, vim muaj qee yam preload, steel siv yuav nruj nreem clamped nyob rau hauv lub kauv zawj, yog li xyuas kom meej ib tug tej yam kev sib cuag cheeb tsam ntawm lub steel siv thiab cov yeeb nkab steel. Txhawm rau tiv thaiv cov hlua hlau los ntawm kev rov qab los thiab poob tawm, ob qho kawg ntawm cov hlua hlau yuav tsum tau welded rau cov yeeb nkab steel. Txhawm rau kom yooj yim inlaying, yuav tsum muaj qee qhov rov qab ntawm cov hlau sawb thiab cov kauv zawj. Yog tias qhov backlash me dhau lawm thiab cuam tshuam tau tsim, cov txheej txheem mosaic yuav tsis ua haujlwm zoo. Tsis tas li ntawd, txoj siv hlua winding steel yuav yeej ib txwm muaj qee qhov rov qab, thiab qhov tshwm sim yog tias txoj siv hlau thiab hauv qab ntawm qhov zawj zawj tsis tuaj yeem koom nrog zoo. Inlay fins tuaj yeem nqa tawm ntawm cov cuab yeej siv dav dav, uas tsis kim, tab sis cov txheej txheem nyuaj thiab cov khoom siv tau qis.
C brazed kauv finned tube
Kev ua ntawm brazed kauv finned hlab yog nqa tawm nyob rau hauv ob kauj ruam. Ua ntej, lub dav hlau ntawm cov hlau sawb yog perpendicular mus rau lub axis ntawm cov yeeb nkab thiab yog lub qhov txhab nyob rau hauv lub puab nto ntawm cov yeeb nkab nyob rau hauv ib tug kauv, thiab ob kawg ntawm cov hlau sawb yog welded rau lub steel yeeb nkab kho, thiab ces. txhawm rau txhawm rau tshem tawm qhov sib txawv ntawm cov hlau sawb thiab cov yeeb nkab steel, cov hlua hlau thiab cov yeeb nkab steel yog welded ua ke los ntawm kev sib tsoo. Vim hais tias txoj kev no kim heev, lwm txoj kev yog feem ntau siv, uas yog, cov yeeb nkab qhwv nrog steel siv yog muab tso rau hauv zinc kua tank rau tag nrho cov kub-dip galvanizing xwb. Txawm hais tias tag nrho cov kev daws teeb meem kub-dip galvanizing yuav tsis nkag mus rau hauv qhov sib txawv me me ntawm cov fin thiab cov yeeb nkab steel, ib txheej galvanized tiav yog tsim nyob rau sab nrauv ntawm fin thiab sab nrauv ntawm cov yeeb nkab steel. Kev siv cov txheej txheem kub-dip galvanized kauv fin tube, vim tias qhov kev txwv ntawm cov tuab ntawm txheej galvanized (thaum txheej txheej galvanized yog tuab, zinc txheej yog qhov tsis zoo thiab tsis yooj yim rau poob), thiab cov kua zinc tsis tuaj yeem tag nrho. nkag mus rau hauv qhov sib txawv, yog li qhov sib txuas ntawm cov fin thiab cov yeeb nkab steel tseem tsis siab. Tsis tas li ntawd, lub tshav kub hloov pauv coefficient ntawm zinc yog me dua li ntawm cov hlau (txog 78 feem pua ntawm cov hlau), yog li lub peev xwm hloov hluav taws xob tsawg. Zinc yog qhov cuam tshuam rau corrosion nyob rau hauv acids, alkalis thiab sulfides, yog li kev siv cov galvanized kauv finned tubes tsis haum rau ua cua preheaters (rov qab los ntawm boiler flue roj pov tseg thaum tshav kub kub).
D High zaus welding kauv fin
High-frequency thiab high-frequency welded kauv finned raj yog tam sim no ib qho ntawm feem ntau siv kauv finned raj.
Tam sim no nws yog dav siv nyob rau hauv hluav taws xob fais fab, metallurgy, cement kev lag luam preheat rov qab thiab petrochemical kev lag luam. High-frequency welding kauv fin tube yog siv cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj ntawm cov high-frequency tam sim no kom sov rau sab nrauv ntawm steel sawb thiab steel yeeb nkab tib lub sij hawm raws li cov hlau sawb raug mob nrog cov yeeb nkab steel, kom txog rau thaum lub welding nto ntawm steel sawb thiab steel yeeb nkab. yas lub xeev los yog melting, thiab vuam yog ua tiav nyob rau hauv ib tug tej yam siab ntawm winding steel sawb. Hom kev siv vuam ntau zaus no yog hom khoom siv vuam theem. Piv nrog rau txoj kev xws li mounting, brazing (los yog ib qho kub-dip galvanizing), nws yog ntau tshaj nyob rau hauv cov nqe lus ntawm cov khoom zoo (siab fin bonding tus nqi txog li 95 feem pua), productivity thiab degree ntawm automation
