Kev Tswj Xyuas Qhov Ntev Dua Rau Cov Khoom Siv Valve
Peb tau ua kom nruj dua hauv cov txheej txheem thiab qhov kawg QC rau lub cev valve, lub kaus mom/lub hau, ISO 5211 lub qhov (bracket), kev sib txuas, thiab lub hauv paus qis dua ntawm lub trunnion kom txiav cov haujlwm rov ua dua thiab ua kom haum sai.
Dab tsi tshiab
-
F2F: lub hom phiaj tsim khoom ±0.15 hli (ua tau raws li daim duab kos); txiav me me tom qab ua tiav ib nrab.
-
PCD/BCD & qhov chaw: CNC qauv drilling + periodic CMM; txoj hauj lwm ib txwm muaj ≤0.05 hli ntawm daim coupon.
-
Thawb ⟂ rau ntsej muag: ≤0.05/100 hli siv kev tshawb nrhiav hauv tshuab.
-
Kev sib khi ntsej muag: Ra 1.6–3.2 µm tshwj tsis yog tias tau teev tseg lwm yam.
-
Cov xov: MUS/TSIS MUAJ-MUAJ ib qho spec; cov cag raug tshem tawm, cov npoo raug chamfered.
Cov ntaub ntawv thiab kev taug qab
-
Daim ntawv tshuaj xyuas hauv hli (nti raws li qhov kev thov).
-
EN 10204 3.1 MTC txuas nrog cua sov No.; xaiv tau ISP/PPAP L2.
Cov lus qhia txog kev kos duab
Txhais cov qauv datum rau F2F/qhov tob ntawm lub ntsej muag (piv txwv li, 0.4 hli), PCD kam rau siab & qhov ntau/Ø, qhov dav/qhov tob ntawm txoj hlua khi, ntug chamfers ze ntawm lub rooj zaum valve, thiab txhua yam txheej/passivation.
Lub sijhawm ua ntej (siv ua piv txwv)
Cov qauv tsim 10-15 hnub tom qab kos npe; cov pawg raws li qhov nyuaj / kev npaj txhij ntawm cov khoom siv.
Hu kom ua haujlwm
Qhia rau peb koj li PO thiab cov yam ntxwv tseem ceeb; peb yuav ua kom daim ntawv tshuaj xyuas sib phim rau koj daim ntawv thov valve thiab xa thawj pawg nrog FAI yog tias xav tau.
