Qhov zoo thiab yam ntxwv ntawm Internally Threaded Copper Tubes
Muab piv nrog cov tooj liab zoo, cov raj hauv cov xov tooj liab tau txais kev hloov kho cua sov kom zoo dua qub. Nyob rau hauv tib tus nqi ntws, lawv cov coefficient ntawm cov cua sov tuaj yeem nce ntxiv1.5 rau 3x, uas zoo heev txo tag nrho qhov loj me thiab peev nqi ntawm cov khoom siv hluav taws xob.

II. Daim ntawv thov zoo ntawm Internally Threaded Copper Tubes
Internally threaded tooj liab raj yog tsuas yog siv rau tshav kub exchangers nyob rau hauv lub tub yees thiab cua txias tshuab, xws li condensers thiab evaporators.
Piv nrog rau cov tsoos tooj liab raj, lawv qhov zoo ntawm daim ntawv thov tau tshwm sim hauv cov hauv qab no:
1.High kub hloov coefficientInternally threaded tooj liab tubes muab zoo kawg li thaum tshav kub kub hloov mus li. Nyob rau tib lub sijhawm ua haujlwm, qhov sib txawv ntawm qhov sib txawv ntawm cov cua sov tuaj yeem nce ntau dua 50%, uas txo cov cua sov hloov pauv loj thiab txuag cov ntaub ntawv thiab chaw teeb tsa.
2. Uniform refrigerant faibCov qauv xov sab hauv ua kom yooj yim rau kev faib khoom thiab kev kub ntxhov ntawm cov pa roj-kua ob-theem refrigerant, inhibits qhov tshwm sim tsis zoo xws li thaj tsam qhuav thiab ntws ntws, thiab txhim kho kev siv tau zoo ntawm cov khoom siv hluav taws xob.
3. High system efficiencyKev siv cov hlua tooj liab sab hauv zoo txo qhov kub ntawm qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob ntawm cov khoom siv hluav taws xob, txo qis compressor zog noj, thiab ua kom lub zog Efficiency Ratio (EER) 5% ~ 10%.
4. Dav adaptabilityInternally threaded tooj liab tubes feature zoo compatibility nrog ntau yam tub yees. Lawv nthuav tawm qhov ua tau zoo ntawm kev hloov pauv cua sov nrog cov tub yees tshiab ib puag ncig tus phooj ywg hloov R22, txhawb kev nyiam thiab siv eco-cov tub yees zoo.
5. Kev tu thiab tu yooj yimCov kauv ntws hauv lub raj txo qis adhesion ntawm nplai, roj av thiab lwm yam sediments, ncua lub voj voog tu, thiab txo cov nqi tu ntev ntev -.
Vuam txheej txheem xav tau rau Internally Threaded Copper Tubes
Xaiv txoj kev vuam
Internally threaded tooj liab raj yog txuas nrog cov yeeb nkab txuas thiab fittings los ntawmbrazinglos yogfusion vuam.
Brazing nta qhov ntsuas kub tsis tshua muaj vuam, ua rau muaj kev hloov pauv me ntsis rau lub microstructure thiab kev ua haujlwm ntawm cov pob qij txha uas tsis tshua muaj kev ntxhov siab. Nws feem ntau yog siv rau lub sijhawm uas xav tau kev sib koom tes siab.
Fusion vuam los nrog qhov kub thiab txias dua thiab dav dua- thaj tsam cuam tshuam, ua rau muaj kev hloov pauv hauv cov qauv thiab kev ua haujlwm ntawm cov pob qij txha. Nws feem ntau yog siv rau cov xwm txheej nrog cov kev cai zoo tib yam ntawm kev sib koom ua ke.
Welding Quality Requirements
Internally threaded tooj liab raj siv nruj cov qauv ntawm welded sib koom ua ke zoo. Kev tsim nyog welds xav tau kev hloov pauv puv thiab du nrog cov ntaub ntawv hauv paus yam tsis muaj qhov tsis xws luag xws li cov hlaws hlaws thiab cov hlaws dai, uas muaj cov npoo du tsis muaj kab nrib pleb, hlawv - los ntawm thiab slag inclusions, thaum lub weld reinforcement yuav tsum tswj nyob rau hauv 1 hli. Lub caij no, cov pob qij txha welded yuav tsum tau tshaj 90% ntawm cov khoom siv lub zog tensile nrog cov hardness piv. Nyob rau hauv cov nqe lus ntawm nruj thiab durability, cov pob qij txha yuav tsum tau zoo heev sealing kev ua tau zoo los tiv thaiv 24-teev siab tuav cov kev ntsuam xyuas ntawm 1.25 lub sij hawm lub siab ua hauj lwm tsis muaj to, thiab xa corrosion kuj sib npaug rau lub hauv paus cov ntaub ntawv uas tsis muaj qhov pom tseeb corrosion cim tom qab simulated ua hauj lwm kev ntsuam xyuas.
Vuam txheej txheem tswj
Txhawm rau lav qhov tsim nyog zoo ntawm cov pob qij txha welded rau hauv cov hlua tooj liab, cov txheej txheem tswj cov txheej txheem yuav tsum tau muab coj los siv thoob plaws hauv cov txheej txheem vuam. Ua ntej welding, tooj liab tube kawg yuav tsum tau polished kom tshem tawm oxide txheej thiab degreased nrog acetone thiab lwm yam kuab tshuaj. Cov cuab yeej tshaj lij xws li cov yeeb nkab clamps thiab qhov chaw tuav yog tau txais kev pom zoo thaum lub sij hawm sib dhos los xyuas kom meej kev sib dhos thiab tiv thaiv kev tsis sib haum xeeb thiab deformation, nrog rau qhov sib txawv clamping tswj ntawm 0.05mm thiab clamping qhov tob teem rau ob zaug ntawm lub raj phab ntsa thickness. Vuam tsis xws li tam sim no thiab voltage yuav tsum tau optimized raws li raj specifications thiab welding hom kom muaj kev sib koom linear zog nyob rau hauv 10 ~ 20J / mm rau ruaj khov cua sov input. Kev sib cuam tshuam thiab sib luag welding txoj kev yog siv rau hauv paus vuam, qhov twg weld hlaws dav yog khaws cia 2 mus rau 3 npaug ntawm tooj liab raj phab ntsa thickness. Rau ntau-txheej txheej thiab ntau- hla vuam, qhov sib cuam tshuam- kis tau kub yog tswj nruj me ntsis hauv qab 150℃kom txo qis kev ntxhov siab thiab cov txheej txheem deformation. Kev kho cua sov los yog kev kho cua sov tuaj yeem ua tau ntawm cov pob qij txha welded thaum tsim nyog los tshem tawm cov kev ntxhov siab seem thiab rov qab kho cov txheej txheem thiab cov khoom siv ntawm cov khoom siv welded.
