Tungsten Copper Contact yog dab tsi?
Tungsten tooj liab tiv tauj yog tungsten tooj liab alloy tiv tauj. Cov hluav taws xob tiv tauj yog cov khoom tseem ceeb hauv cov hluav taws xob hluav taws xob thiab cov twj siv hluav taws xob siab thiab qis. Lawv yog lub luag hauj lwm rau kev sib txuas thiab disconnecting lub circuits thiab nqa cov tam sim no nyob rau hauv lub coj circuits. Txij li thaum nws qhia nyob rau hauv 1935, tungsten tooj liab hluav taws xob tiv tauj cov ntaub ntawv tau lug siv nyob rau hauv tsis siv neeg keyboards, universal circuit breakers, thiab molded case Circuit Court breakers. Tungsten thiab tooj liab tsis yaj nyob rau hauv ib leeg los yog tsim intermetallic compounds. Cov qauv ntawm ob-theem monomers yog "pseudo-alloy".
Tungsten tooj liab tiv taujmuaj zoo heev arc hlawv tsis kam thiab tsis kam rau vuam. High-voltage hu tuaj yeem ua rau ntau yam duab (extrusion / sintering / melting) los ntawm hmoov metallurgy. Cov ntsiab lus tungsten yog li 50% -90%. Tungsten tooj liab tiv tauj rau hluav taws xob yog siv nyob rau hauv nruab nrab thiab siab voltage hluav taws xob hloov. Nws feem ntau yog siv nyob rau hauv high voltage Circuit Court breakers, load switches, transformer keyboards, kais changers thiab electrodes tsuas yog siv rau vuam.
Qhov zoo
Hluav taws xob tiv tauj ua los ntawm tungsten tooj liabmuaj zoo arc hlawv tsis kam thiab tsis kam mus rau fusion vuam, zoo arc tawg kev ua tau zoo, zoo hluav taws xob thiab thermal conductivity, me me thermal expansion, tsis softening ntawm kub, siab zog, siab ceev, siab hardness thiab lwm yam ntxwv. Nws muaj hluav taws xob zoo heev thiab thermal conductivity, zoo kub siab zog thiab tej yam plasticity. Nws tsis tsuas yog tuav lub siab kub tsis kam, siab hardness thiab tsis tshua muaj expansion coefficient ntawm tungsten, tab sis kuj tswj lub siab hluav taws xob conductivity thiab thermal conductivity thiab zoo plasticity ntawm tooj liab.
Siv
Tungsten tooj liab hluav taws xob tiv taujyog dav siv los ua kev sib cuag thiab tiv thaiv nplhaib rau high-voltage, ultra-hydraulic keyboards thiab Circuit Court breakers, rau hluav taws xob cua sov roughing anvil cov ntaub ntawv, tsis siv neeg submerged arc vuam conductive nozzles, ntshav tej tshuab nozzles, hluav taws xob welders, vuam taub hau ntawm taub qab vuam, dov. vuam log, roj sealing electrodes thiab spark electrodes, chaw vuam, pob tw vuam cov ntaub ntawv, thiab lwm yam.
1. Resistance vuam electrode
Ua ke qhov zoo ntawm tungsten thiab tooj liab, kub tsis kam, arc hlawv tsis kam, siab zog, siab tshwj xeeb gravity, zoo hluav taws xob thiab thermal conductivity, yooj yim txiav thiab ua, thiab muaj hws txias, thiab lwm yam.
Cov yam ntxwv, vim lub siab hardness, siab melting point thiab anti-adhesion yam ntxwv ntawm tungsten, nws yog feem ntau siv raws li qhov projection vuam thiab taub qab vuam electrodes nrog tej yam hnav tsis kam thiab kub tsis kam.
2. Hluav taws xob hluav taws xob electrode
Thaum cov pwm ua los ntawm tungsten steel thiab kub resistant superhard alloy yuav tsum tau electro-etched, lub zoo tib yam electrode muaj loj poob thiab qeeb ceev. Lub siab electro-corrosion ceev, tsawg poob tus nqi, meej electrode zoo thiab kev ua tau zoo ntawm tungsten tooj liab tuaj yeem ua kom paub tseeb tias qhov tseeb ntawm cov txheej txheem ua tau zoo heev.
3. High-voltage paug raj electrode
Thaum lub tshuab nqus tsev vacuum muaj zog ua haujlwm, qhov kub ntawm cov khoom siv sib txuas yuav nce los ntawm ntau txhiab degrees Celsius hauv ob peb feem kaum ntawm ib thib ob. Lub siab ablation tsis kam, siab toughness, zoo hluav taws xob conductivity thiab thermal conductivity ntawm tungsten tooj liab muab qhov tsim nyog rau kev ua haujlwm ruaj khov ntawm lub raj xa tawm.
4. Cov khoom ntim khoom siv hluav taws xob
Nws muaj ob qho tib si tsis tshua muaj kev nthuav dav ntawm tungsten thiab siab thermal conductivity ntawm tooj liab. Nws thermal expansion coefficient thiab hluav taws xob conductivity thiab thermal conductivity tuaj yeem hloov tau los ntawm kev kho cov khoom muaj pes tsawg leeg.
Tungsten tooj liab tiv tauj rau hluav taws xob
Peb MuajTungsten Brazed Contacts Rivetsyog qhov kev xaiv zoo tshaj plaws rau cov neeg siv khoom vim lawv muaj ntau yam zoo. Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, tungsten zoo heev lub cev thiab hluav taws xob zog, raws li zoo raws li nws dav siv tau nteg lub hauv paus ruaj khov rau cov khoom. Ntau hom kev xaiv customization tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv. Kev hloov kho qhov loj tuaj yeem hloov kho rau ntau yam khoom siv, kev ua haujlwm parameter customization tuaj yeem kho cov khoom ntsuas kev ua tau zoo raws li cov xwm txheej tiag tiag, thiab kev hloov kho tshwj xeeb muab cov kev daws teeb meem tshwj xeeb rau daim ntawv thov tshwj xeeb scenarios.
