Brazing txheej txheem rau Phaj-fin Thaum tshav kub kub Exchangers

Taw qhia

Phaj-fin heat exchangers (PFHEs) yog qhov tseem ceeb hauv kev lag luam xws li tsheb, aerospace, thiab cryogenics. Cov khoom siv compact, cov khoom siv tau zoo hloov cov cua sov ntawm cov kua dej thaum tswj kev ua haujlwm zoo thiab txo qis kev poob siab. Kab lus no tshawb txog cov txheej txheem brazing siv los tsim PFHEs, hais txog nws qhov tseem ceeb thiab cov txiaj ntsig.

Nqus Brazing: Ib txoj hauv kev pov thawj

Ntawm Wuxi Jiushengyuan Science & Technology Co., Ltd. (KIUSIN), peb siv lub tshuab nqus tsev brazing los tsim PFHEs zoo. Nov yog ib qho piv txwv ntawm cov txheej txheem:

1.Plate Assembly: PFHE core muaj alternating daim hlau thiab fins, txhua phaj coated nrog ib tug nyias zaj duab xis ntawm braze hlau ntawm ob sab. Precise alignment ntawm cov fins yog guaranteed thaum lub sij hawm sib dhos meticulous.

2. Lub tshuab nqus tsev vacuum: PFHE thaiv tau muab tso rau hauv lub tshuab nqus tsev vacuum. Cov txheej txheem brazing tshwm sim nyob rau hauv lub tshuab nqus tsev, tshem tawm qhov xav tau ntawm flux. Qhov kub ntawm lub cub tawg feem ntau ncav cuag 580 ° C.

3.Brazing: Thaum lub sij hawm brazing, lub braze hlau melts thiab ntws, tsim muaj zog bonds ntawm daim hlau nyob ib sab. Cov khoom ntawm lub block ua ruaj khov, ua kom muaj cov qauv zoo.

4.Attachments: Tom qab brazing, ntxiv cov khoom xws li ib nrab-pipe headers, nozzles, kev txhawb nqa brackets, thiab lifting trunnions yog welded rau hauv lub hauv paus, txhim khu kev ua haujlwm thiab cov dej ntws hauv PFHE.

Qhov zoo ntawm Vacuum Brazing

1.Hermetic Sealing: Lub tshuab nqus tsev vacuum ua kom lub foob kaw ntom nti, tseem ceeb heev rau cov ntawv thov cryogenic uas tswj qhov kub thiab txias yog qhov tseem ceeb.

2.Uniform Thaum tshav kub kub Distribution: Kev tswj lub tshuab nqus tsev ib puag ncig tso cai rau cov cua sov tsis sib xws, txo qis thermal stresses thiab distortion.

3.Clean thiab Flux-Free: Tsis zoo li cov txheej txheem brazing ib txwm, lub tshuab nqus tsev brazing tsis tas yuav tsum muaj flux, tshem tawm qhov xav tau ntawm kev ntxuav tom qab brazing thiab txo qhov kev pheej hmoo ntawm kev sib kis.

4.High-lub zog pob qij txha: Cov ntawv cog lus metallurgical tsim thaum lub tshuab nqus tsev vacuum ua rau cov pob qij txha muaj zog, ruaj khov muaj peev xwm tiv taus siab thiab kub sib txawv.

Raws li lub chaw tsim khoom PFHE, KIUSIN muab cov kev txawj ntse, kev siv tshuab siab heev, thiab kev cog lus rau qhov zoo. Peb lub tshuab nqus tsev-brazed PFHEs npog ntau qhov kub thiab txias siab txog 130 bar. Txawm hais tias rau lub tsheb radiators, cua compressors, lossis cov tshuab cryogenic, peb cov PFHEs xa cov hluav taws xob hloov tau zoo thiab kev ntseeg tau.
