5. Hom xov twg koj xaiv?
Xaiv qhov tseeb xov yog nyob ntawm koj cov cuab yeej, cov cheeb tsam teeb tsa, thiab cov kev xav tau ua haujlwm.
Xaiv NPT Yog:
Qhov project yog nyob rau hauvNorth America
Koj xav tau aSiab -}} Kev sib txuas nruj
Cov cuab yeej qhia tshwj xeeb xav tauNtt xwb
Piv txwv:Cov roj ua kom zoo, cov nroj tsuag tshuaj, tshuab hnyav, roj roj.
Xaiv PG yog tias:
Koj tab tom kho lossis hloov chaw rauCov Khoom Siv European
Cov txee hluav taws xob lossis cov txheej txheem conduit tshwj xeeb siv PG
Koj tab tom ua haujlwm nrog cov neeg xa khoom hauv Niche lag luam
Piv txwv:Cov cuab yeej ua legacy, qub tswj vaj huam sib luag, German - ua tshuab ua ntej 2000.
Xaiv metric (m) yog tias:
Koj ua haujlwmCov Khoom Siv Hluav Taws Xob Tshiab lossis Cov Khoom Siv Thoob Ntiaj Teb
Daim ntawv thov yuav tsum tauCov Qauv niaj hnub thiab kev sib khi tau yooj yim
Koj xav tau lub neej yav tom ntej - pov thawj thiab dav tshaj xov xov
Piv txwv:Automation, Robotics, hnub ci zog, cov tub rog ua dej hiav txwv, OEM raug.
6. Kev pom zoo zaum kawg: Qhov xov zoo tshaj plaws rau feem ntau cov neeg yuav khoom
Yog tias daim ntawv thov tsis tas yuav muaj ib tus qauv tshwj xeeb,Metric (m) xov kab cableyog qhov kev xaiv nyab xeeb tshaj plaws thiab feem ntau. Lawv muab qhov zoo tshaj plaws ntawm:
Kev sib haum
Installation Yooj Yim Installation
Ntiaj Teb Txaus
Yav tom ntej - ntawv pov thawj tsim
Txhim khu kev qha O - Nplhaib Sealing
Txawm li cas los xij, ib txwm ua raws li cov kev qhia tshwj xeeb ntawm cov khoom lag luam cov khoom siv kom tsis txhob muaj kev tsis sib haum xeeb lossis tsis nyab xeeb.
7.Txhua cov ntsiab cai, cov qauv kawm thoob ntiaj teb, thiab cov lus qhia kev xaiv rau NPT, PG, thiab metric cable txuas xov.
1. Nkag siab xov geometry thiab nws cuam tshuam li cas rau kev sib khi
Qhov ntau tshaj plaws qhov sib txawv ntawm NPT, PG, thiab metric xov lus dag nyob rau hauv lawv cov geometry.
Xov geometry ncaj qha txiav txim siab zoo npaum li cas cov cable gland ntsaws ruaj ruaj rau hauv ib lub vaj huam sib luag rau hauv ib lub vaj huam sib luag rau hauv kev co, siab, lossis thermal expansion.
Npt xov geometry
Npt xov yogtus hlau, feem ntau ntawm 1℃47 lub kaum sab xis. Cov taper no yog dab tsi tso cai rau cov xov rau wedge nruj nreem ua ke. Thaum tus txiv neej tis cable gland yog ntsia hlau rau tus poj niam NPT txuas lossis thaiv cov kab ke, kev sib cuag nto nce ntxiv thaum nws nruj, tsim ibSiab -} ncu foobCov. Qhov no yog vim li cas npt yog nrov nyob rau hauv cov roj av, roj pipelines, thiab lwm qhov kev sib tw ib puag ncig.
Txawm li cas los xij, qhov kev tsim qauv no txhais tau tias:
Lub installer yuav tsum thov cov kab xev ptfe lossis sib foob.
Tshaj {- zawm tau tuaj yeem tawg yas condle.
Nyob rau hauv -} zawm cov txiaj ntsig hauv kev xau.
Pg xov geometry
Pg xov siv aSib sau profilenrog qhov tob tob tob. Vim hais tias cov xov tsis tau tsim, pg sib txuas feem ntau ntawm zuaj ntau zog, thaj chaw thaj chaw, thiab cov xauv ua kom ua tiav lub foob. Lub xov rooted txo kev sib txhuam thiab maj mam rau cov ntaub ntawv softer, uas yog vim li cas pg muaj tshwm sim hauv cov khoom hluav taws xob thaum ntxov.
Metric Xov Geometry
Metric xov muaj aDaim duab peb sab(60℃flank kaum sab xis) thiab ancaj (parallel) xov tsimCov. Sealing yog tiav los ntawm:
a tiaj tus washer lossis o - ntiv nplhaibcompressed nruab nrab ntawm lub caj pas thiab ntim
Qhov kev sib ze dav ntawm cov ntsuas xov
Qhov no ua rau Metric glands heev ntseeg tau rauIP67, IP68, thiab IP69K waterproof thiab plua plav tshuab.
2. Ntiaj teb kev ua haujlwm thiab vim li cas kev ua lag luam nyiam Metric Threads hnub no
Thoob Ntiaj Teb, Cov Koom Haum Sib Txawv Cov Qauv sib txawv cuam tshuam:
Npt→ Ansi / ASME (USA, Canada, Mexico)
Pg→ DIN 40430 (laus dua EUROPE EUROPE)
Metric (m)→ ISO 262 / ISO 965 (thoob ntiaj teb)
Hauv 20 xyoo dhau los,Metric xov tau dhau los ua tus qauv tseem ceeb, tshwj xeeb tshaj yog nyob rau Asia, Europe, Middle East, thiab South America. Cov kev hloov pauv no tau tshwm sim rau ntau yam:
A. ISO qauv
Feem ntau cov khoom lag luam cov khoom lag luam nyiam ISO cov qauv vim tias lawv tau txais thiab yooj yim rau kev xa tawm.
B. Kev koom kev sib xyaw nrog kev sib raug zoo
Metric xov haum yooj yim rau hauv:
Aluminium midting boxes
Stainless Hlau Panels
Abs lossis Polycarbonate tso cai
yas davhlau nyob ruaj
Metric xov tseem txo txoj kev pheej hmoo ntawm tus ntoo khaub lig {{}}} xov.
C. Waterproof System Yuav Tsum
Raws li Kev Lag Luam Txais IP67-IP69K Waterproof Specifications:
Metric glands muab ntau dua kev sib khi
O {- Nplaum Tsim Tsev Kawm Ua Tau Zoo
D. Hloov rau PG Xov
Cov cuab yeej niaj hnub tau hloov mus deb ntawm pg threading, ua m xov uas nyiam cov hluav taws xob thiab cov tshuab hluav taws xob.
3. Thov {{- Raws Xaiv: Kev Coj Xov Hom Rau Kev Lag Luam
Txhawm rau xaiv cov xov xov zoo, cov neeg yuav khoom yuav tsum xav txog cov kev ua haujlwm ib puag ncig thiab ua haujlwm.
NPT: Qhov zoo tshaj plaws rau high - pa taws ib puag ncig
NPT xov Excel nyob rau hauv:
Roj av thiab petrochemical nroj tsuag
Offshore rigs
Boiler Chav
Hnyav - DiseYERTUSTHAULIC FAIS
siab - cua siab kua dej
Vim yog cov xov uas muaj tapered, npp ntawm cov kev co thiab lub siab zoo heev.
PG: Zoo tshaj plaws rau cov tshiab hluav taws xob tshuab hluav taws xob
Pg xov nyob tseem ceeb yog thaum:
OEM cov khoom yog laus dua 2000
German lossis Europe Legacy Panels yuav tsum tau hloov
Cov cim hauv zos lossis cov catchs catouts siv pg sizing
Tus qauv no txuas ntxiv muaj tab sis yog ua tsis tshua muaj kev tsim qauv tshiab.
Metric: Zoo Tshaj Rau Cov Machinery Thiab Cov Thoob Ntiaj Teb
Metric xov yog qhov kev xaiv ua neej ntawd rau:
Tus Vaj Huam Sib Luag Hluav Taws Xob Hluav Taws Xob Tshiab
Hnub Ci Thiab Cua Zog Teev
