Lub Vuam Ntawm Lub Cev Windings ncaj qha txiav txim siab lub neej ntawm lub cev muaj zog

Lub vuam ntawm lub cav windings ncaj qha txiav txim siab lub neej ntawm lub cev muaj zog

 

Lub cev muaj zog winding welding yog cov txheej txheem tseem ceeb ntawm cov txheej txheem ntawm lub cev muaj zog, xws li vuam ntawm winding lub ntsiab xaim thiab lub ntsiab xaim, vuam ntawm lub ntsiab hlau thiab cov hlau lead, vuam ntawm tooj liab rotor qhia sawb thiab lub nplhaib kawg. , thiab lwm yam, tag nrho cov uas yuav ncaj qha cuam tshuam rau kev khiav hauj lwm kev ntseeg siab thiab qib zoo ntawm lub cev muaj zog. Lub cev muaj zog ntawm ntau hom lossis ntau thiab tsawg suav nrog cov txheej txheem vuam nrog lawv tus kheej tshwj xeeb thiab feem ntau tsis yog sib npaug. Niaj hnub no, Ms. Shen yuav tham nrog txhua tus neeg txog cov txheej txheem winding welding.

Vuam txoj kev tuaj yeem muab faib ua ob pawg loj: fusion vuam thiab brazing. Fusion welding ncaj qha melts ob lub workpieces ua ke, thiab cov hlau ntawm qhov sib koom ua ke yuav tsum tau rhuab mus rau lub xeev molten kom tiav qhov vuam. Brazing txais yuav cov khoom siv hlau nrog qhov qis melting point tshaj lub hauv paus hlau raws li cov muab tub lim, heats lub vuam thiab solder hlau mus rau qhov kub siab tshaj qhov melting point ntawm cov hlau solder thiab qis dua lub melting kub ntawm lub hauv paus hlau, thiab siv. kua nplaum hlau kom ntub lub hauv paus hlau, sau qhov sib koom ua ke thiab diffuse nrog lub hauv paus hlau kom ua tiav kev sib txuas vuam. Feem ntau ntawm cov vuam ntawm lub cev muaj zog windings txais yuav brazing, txawm hais tias tseem muaj fusion vuam, tab sis feem ntau nws yog ib qho tsim nyog los pab nyuaj brazing kom ua rau fusion vuam tsis xws luag.

 

Cov txheej txheem welding feem ntau rau lub cev muaj zog windings

 

Silver brazing (gas vuam)

 

Txoj kev vuam no tsim nyog rau lub sijhawm uas muaj kev ua haujlwm loj, qhov kub thiab txias thiab kev ntseeg siab, thiab tseem yog txoj kev vuam siv los ntawm cov tuam ntxhab feem ntau. Cov khoom siv vuam yog acetylene oxygen vuam phom. Thaum vuam, txhawm rau tiv thaiv scalding ntawm lub cev muaj zog hlau nyob ze ntawm cov hlau rwb thaiv tsev, cov kab taub hau yuav tsum tau qhwv nrog cov hlua asbestos dipped hauv dej. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los tiv thaiv solder thiab flux los ntawm ntws mus rau hauv qhov sib txawv ntawm lub kauj, scalding lub rwb thaiv tsev thiab ua rau luv luv Circuit Court.

Soldering

 

Soldering yog ib qho yooj yim rau kev khiav lag luam thiab qhov taw tes soldering yog ruaj, yog li nws yog feem ntau siv, tab sis qhov ua hauj lwm kub yog tsawg. Feem ntau siv soldering yog soldering hlau soldering thiab pouring tin. Thaum tus xov tooj ntawm vuam hlau xaus yog loj, txoj kev ntawm pouring tin yuav siv tau. Vim qhov kev txwv ntawm qhov tsis tshua muaj melting point ntawm solder tin, nws tsuas yog siv nyob rau hauv me me motors thiab lub cev muaj zog windings nrog tsawg kub nce.

 

arc vuam

 

Thaum tus neeg xyuas pib ntawm winding yog nyias, arc vuam siv tau rau vuam. Cov yam ntxwv ntawm arc vuam yog tias tsis tas yuav tsum muaj flux, uas yog ceev thiab yooj yim, tab sis thaum muaj ntau qhov sib txuas sib txuas thiab ntau lub taub hau hlau, yog tias kev ua haujlwm tsis txawj, nws yog qhov yooj yim kom nco vuam lossis vuam khov kho.

Copper-aluminium oxygen welding

 

Thaum welding, tooj liab hlau los yog qhov sib txuas ntawm cov hlau lead hlau yog thawj tin txuas, thiab tom qab ntawd cov hlau nplaum txhuam yog sib tw rau ntawm cov hlau hlau, thiab cov hlau txhuas yog me ntsis siab dua cov hlau hlau. Tom qab ntawd siv ib txheej ntawm aluminium welding hmoov, yaj cov txhuas hlau nrog cov nplaim nruab nrab ntawm cov roj vuam, kom cov txhuas fused rau saum cov tooj liab los ua ib qho kev sib koom ua ke. Txoj kev no yog siv nyob rau hauv kev sib txuas ntawm cov hlau tseem ceeb thiab cov hlau lead hauv ntau lub tshuab fais fab.

TIG welding

 

Argon arc vuam yog ua raws li lub hauv paus ntsiab lus ntawm kev siv cov arc vuam zoo tib yam, kev siv cov roj argon ntawm kev tiv thaiv cov hlau vuam consumables, los ntawm cov tam sim no siab los yaj cov vuam consumables ntawm lub welded substrate rau hauv lub xeev cov kua los tsim ib tug molten pas dej ua ke, yog li ntawd. welded hlau thiab vuam consumables kom ua tiav metallurgical ua ke ntawm vuam tshuab, vim lub siab kub yaj welding tas li xa argon, kom cov vuam consumables tsis tuaj yeem tiv nrog oxygen hauv huab cua, yog li tiv thaiv oxidation ntawm vuam consumables. Qhov no welding plays lub luag haujlwm zoo hauv kev vuam zoo ntawm ntau tig windings.

High zaus induction brazing

 

Induction brazing yog vuam cov hlau workpiece (feem ntau tooj liab) muab tso rau hauv induction kauj, los ntawm high-frequency alternating tam sim no, tsim induction electromagnetic teb, coupling nyob rau saum npoo ntawm lub workpiece los tsim induced electromotive quab yuam, nyob rau hauv cov hlau nto los tsim induction. eddy tam sim no, cia siab rau ntawm cov hlau nto generated eddy tam sim no cua sov, nyob rau hauv lub vuam feem feem ntau yuav coated nrog vuam hmoov, kom txog rau thaum lub workpiece ncav cuag lub solder melting kub thaum welding yuav ua tau, induction brazing yog tam sim no lub ntiaj teb no lub cleanest thiab environmentally phooj ywg cua sov vuam. txoj kev. Hom vuam no nyob rau hauv daim ntawv thov tooj liab bar rotor ntau dua, vim hais tias vuam tib lub sij hawm ntawm ob peb vuam pob qij txha nyob rau tib lub sij hawm ua hauj lwm, qhov sib xws ntawm cov txheej txheem tsis yog zoo dua, tab sis kuj zoo solder sib koom deformation, tsis muaj teeb meem los ntawm ergonomics, kev ntseeg siab thiab kev zoo nkauj thiab lwm yam yog cov txheej txheem zoo dua, tab sis vim tias cov cuab yeej siv tau zoo heev, cov nqi sib txuas induction coil kuj tseem kim, yog li tsis yog txhua tus neeg tsim khoom siv lub tshuab vuam no.

Nruab nrab zaus induction brazing

 

Cov khoom siv nruab nrab zaus induction brazing yog los sib sau ua ke ntawm qhov chaw ntxuav cov khoom ua haujlwm ua ke hauv ib lub voj voog, thiab muab tso rau ze ntawm qhov sib koom ua ke lossis nruab nrab ntawm qhov sib koom ua ke.

Cov khoom siv nruab nrab zaus induction brazing tuaj yeem hloov cov cua sov oxyacetylene, thee qhov cub cua sov, lub thawv hluav taws xob rauv cua sov thiab lwm txoj hauv kev rov qab cua sov rau brazing thiab quenching cua sov kho. Nws tuaj yeem txhim kho cov khoom zoo, txuag hluav taws xob zoo, thiab txhim kho kev ua haujlwm. Thaum lub workpiece thiab muab tub lim hlau yog rhuab mus rau ib tug kub me ntsis siab tshaj qhov melting point kub ntawm muab tub lim hlau, cov muab tub lim hlau melts (lub workpiece tsis melted), thiab nyob rau hauv lub capillary txiav txim yog nqus mus rau hauv thiab ntim nrog cov khoom workpiece. , cov kua muab tub lim hlau thiab cov khoom ua haujlwm hlau diffuse thiab yaj ib leeg, thiab kev sib koom ua ke ntawm brazing yog tsim tom qab txias txias. Nta ntawm nruab nrab zaus induction brazing khoom:

1 Vim hais tias lub hauv paus ntsiab lus ntawm nruab nrab zaus induction cua sov yog electromagnetic induction, nws cov cua sov yog tsim los ntawm lub workpiece nws tus kheej, cov cua sov txoj kev muaj ib tug ceev ceev cua sov tus nqi, tsawg heev oxidation, siab kub efficiency, zoo txheej txheem repeatability, tsuas yog ib tug heev me ntsis decolorization ntawm lub hlau nto, me ntsis polishing tuaj yeem kho qhov chaw kom pom qhov ci ci, thiaj li ua tau zoo kom tau txais cov khoom siv tas li thiab zoo ib yam.

Cov cua sov tsis sib xws, kev tswj qhov kub thiab txias, cov cua sov tsis sib xws, kom ntseeg tau tias qhov sib txawv ntawm qhov kub thiab txias ntawm lub rooj cua sov yog me me. Kev tswj qhov kub thiab txias tso cai rau kev tswj xyuas qhov kub thiab txias kom paub meej cov khoom rov ua dua.

Cov vuam ntawm cov tooj liab liab rotor qhia sawb ntawm nruab nrab zaus induction brazing hauv av yog dav siv ntau dua, thiab cov txheej txheem vuam muaj cov kev cai nruj dua rau kev txiav, sib sau thiab cov duab ntawm lub hau npog, txwv tsis pub cov vuam nyhuv yuav raug txo kom tsawg.

 

Raws li cov ntaub ntawv saum toj no, txhua lub tuam txhab tsim hluav taws xob yuav tsum sib txuas lawv tus kheej cov khoom siv thiab cov yam ntxwv ntawm cov khoom lag luam rau kev ntsuam xyuas, tab sis vuam kev ntseeg tau zoo yog qhov tseem ceeb ntawm kev tsim khoom.
