Cov ntsiab lus tseem ceeb:

Lub vuam interface yuav tsum muaj kev ywj pheej ntawm cov oxide txheej;

Lub ntsuas kub brazing feem ntau tswj tau thaum 850 yog muaj ~ 950 degree;

Lub nqus tsev kawm ntawv yuav tsum qis dua 10⁻⁴pa.

{{02. Kev Kho Mob: Nickel Plating Txheej Txheem

Lub Hom Phiaj: Ua kom zoo tshaj plaws, oxidation tiv, thiab kev sib txhuam tsis kam;

Plaster Thickness: Feem ntau 2 \\ ~ 5μm;

Txheej Txheem Hom:

Tshuaj lom neeg cov leeg npib: haum rau cov txheej txheem nyuaj;

Electroplating npib tsib xee: haum rau huab hwm coj loj;

Cov nyhuv: txuas ntxiv kev pabcuam lub neej ntawm tungsten contacts thiab txhim kho kev ruaj khov;

Lo lus tseem ceeb: npib tsib xee-plated tus neeg hu, brazed tungsten contactions .

Vim nws cov khoom siv hluav taws xob siab dua thiab cov hluav taws xob, cov neeg siv hluav taws xob tau siv dav hauv cov hluav taws xob txuas nrog thiab txuas ntxiv:

1. tsheb horn tungsten tiv tauj

Thov rau ntau 12v lossis 24V tsheb fais tshuab raj;

Yuav tsum muaj cov arc muaj zog, tsis tau yaj vuam, thiab cov lus teb nrawm;

Hlau-based tungsten tiv tauj yog siv rau cov qauv kev lag luam;

Tooj liab-raws tus neeg hu ua yog siv rau high-kawg thiab ruaj khov kub .

{{02. Smart Tsev Relay Tungsten Contactions

Siv rau cov teeb pom kev ntse, cov tshuab kev ruaj ntseg hauv tsev, thiab lwm yam.;
Yuav tsum tau ua ntau zaus thiab cov sij hawm ntev ruaj khov;
Feem ntau ua rau siv tungsten rod sleit tod + tooj liab rivetts + Nickel-Plated Crazing txheej txheem;
