Cov Kev Xam Hluav Taws Xob
Yuav tsum muaj lub zog cua sov (kW) =[Tag Nrho Weld cheeb tsam (MM²) × Fais hau ceev (w / mm²) × kev nyab xeeb muaj kev nyab xeeb
Cov ntawv tseem ceeb piav qhia:
1. weld cheeb tsam (a)
- Xam:= ntev (hli) × dav (hli)Rau cov pob qij txha
- Rau cov chaw ncig:= π × (radius) ²
- Suav nrog txhua qhov tib si weld aav hauv ntau-feem suptures .
{{02. fais fab ntom ntom (Pd)
- Tej hlau: 0.3-1.2 w / mm²
Tooj Liab / Aluminium: 0.3-0.6 w / mm²
Titanium / Hlau: 0.8-1.2 W / MM²
- Ceramics / Composites: 1.5-3 w / mm²
- Siab dua pd =} kub sai dua tab sis muaj kev pheej hmoo thermal distortion
3. kev nyab xeeb rau kev nyab xeeb (SF)
- Yam tsawg kawg sf=1.5(npog cov khoom cua kub, kev laus)
- Rau high-fructputhed:Sf=2.0(txhawb nqa thermal load)
Cov piv txwv tiag tiag:
- Cais: Ev roj teeb busbar (tooj liab-txhuas, 150 hli x 50 hli)
- Weld cheeb tsam: * {= 150 × 50=7}, 500 mm² *
- Lub Zog Hluav Taws Xob: * Pd=0.5 w / mm² * (rau cu-al)
- Kev Nyab Xeeb Kev Nyab Xeeb: * Sf {= 1.8 * (Ntau Lawm-Tseem Ceeb)
- Tshuab Fais Fab Yuav Tsum Tau:
- 7,500 mm² × 0.5 w / mm² _ 1.8=6}}}, 750 w → → Xaiv ntau dua lossis sib npaug rau 7 KW system
Cov tshev tseem ceeb:
✅ Kev Ua Haujlwm Siab: Xyuas kom cov khoom muaj peev xwm hydraulic tau ntsuas laij duab weld quab yuam:
Yuam kev (kn) {= qhov siab (mpa) × cheeb tsam (mM²)
(e {. g}}}}}}}}} ×} {5} → verry tshuab ntaus nqi)
✅ Thermal Rov Qab: Rau Cyclic Ntau Lawm, Tshuab Yuav Tsum Rov Tshem Tawm Qhov Kub Tsis pub dhau 10-20 feeb ntawm kev voj voog .
Cov lus qhia Pro Pro:
- Multi cheeb tsam cua sov: Rau qhov loj / seem seem, qhia meej cov tshuab nrog cov hoob kub ywj siab kom tiv thaiv cov pob txias txias.
- Yav Tom Ntej-Ntawv Pov Thawj: Loj zog rauTom ntej-Gor Ntu Tsim(e {{. g .}}} paab lub xeev roj teeb) {}}
- HAIVI TSHUAB: Cia li laij lub zog / yuam kom cov kev xav tau thaum nkag mus rau cov khoom siv thiab qhov loj me .
Txoj cai ntawm tus ntiv tes xoo:
"Koj lub tshuab KW yuav tsum tau tshaj li koj qhov chaw weld ntau tshaj plaws (mM²) los ntawm 0 {{{}}}}}}}}}}}."
Muaj zog sib txuam muaj zog tshem tawm kev ua tsis tiav thiab ua kom muaj kev ntsuas ROI - ntsuas ob zaug, Weld ib zaug!
