BSP vs . g xov: sib txawv
| Yam zoo | BSPP (g xov) | BSPT (R / RP xov) |
|---|---|---|

Tseem ceeb qhia meej
BSP yog lub kaus zaum:
BSPP=} parallel xov =G threads(Iso {228-1) .
Bspt{{0= taperre xov =R / rp xov(Iso {7-1) .
G xov tsuas yog parallel:
"G" yeejhais txogBSPP (e.g., G1/2", G1").
Lub ntsaws ruaj vias ntawmSab nraud Cheebtsam(e {{. g .}, washer).
BSPT siv R / RP cim:
R: Xov sab nraud (e {. g ., R1 / 2 ") {4}
Kheej: Xov tapered tapered (e {{{0} g ., rp1 / 2 ").
Lub ntsaws ruaj vias ntawmTEED KEV PAB(Tsis muaj washer xav tau) .
Tsis txhob sib xyaw BSPP (G) & BSPT (R / RP):
Partel (g) thiab tapered (r) xovtsis tuaj yeem foob lossis xov ua ke.
BSP vs . npt (Asmeskas Txuj):
BSP: 55℃lub kaum, 1:16 taper (bspt tsuas) .
Npt: 60℃kaum, 1:16 taper .
⚠️ Tsis sib haum- sib xyaw ua rau txeej / xov kev puas tsuaj .
Yuav ua li cas txheeb xyuas
G (BSPP):
Xov yogsib raws(tas li cov taub uas hla) .
Cim nrog "G" (e.g., G3/4).
BSPT (R / RP):
Xov yogtus hlau(txoj kev sib txawv hloov) {.
Cim nrog "R"(sab nraud) lossis"Kheej"(sab hauv) .
Lub ntsiab
G xov=bspp=} parallel +Xav tau Washer foob(Iso {228-1) .
Bspt ≠ g xov=} tapered +Tus Kheej Sealing(Iso {7-1) .
Ib txwm sivCov cim (G, R, RP)- zam tsis meej "BSP" ib leeg .
💡 Tsim cov hau: SivBSPT (R / RP)rau cov tshuab siab;BSPP (G)rau cov khoom siv qis / ntim-fim-ntsej muag .
