FAQ
Q1: C70600 tube loj tshaj plaws rau cov khoom siv hluav taws xob yog dab tsi?
3/4" OD x BWG 18 (19.05mm x 1.24mm phab ntsa) yog qhov loj tshaj plaws.Ntau lub tuam txhab hluav taws xob thiab cov khoom siv hluav taws xob hauv hiav txwv siv qhov loj me no. Qhov thib ob feem ntau yog 1 "OD x BWG 16 (25.4mm x 1.65mm phab ntsa).
Q2: Dab tsi yog BWG sawv rau hauv lub raj loj?
BWG stands rau Birmingham Wire Gauge.Nws yog tus qauv rau hlau thiab raj phab ntsa thickness. Rau BWG, tus lej ntsuas loj dua txhais tau tias cov phab ntsa nyias nyias. BWG 22 yog nyias (0.71mm). BWG 10 yog tuab (3.40mm). Tsis txhob cuam tshuam nrog SWG (Standard Wire Gauge), uas txawv me ntsis. ASTM B111 siv BWG.
Q3: Kuv yuav hloov BWG rau mm li cas?
Siv daim ntawv hloov dua siab tshiab saum toj no. Rau kev siv ceev:BWG 18=1.24mm, BWG 16=1.65mm, BWG 14=2.11mm. Cov mis hloov dua siab tshiab tsis yog linear. Nco ntsoov xa mus rau ib daim ntawv qhia lossis nug koj tus neeg muag khoom kom paub meej.
Q4: Dab tsi yog qhov kam rau ntawm C70600 raj OD?
± 0.004 nti (± 0.10mm) rau OD txog 1 nti.Rau ODs loj, kev kam rau siab nce me ntsis. Qhov kev zam no tso cai rau lub raj kom haum rau hauv lub raj ntawv lub qhov. Yog tias koj daim ntawv raj muaj qhov nruj dua, koj yuav tsum tau qhia txog kev cai OD kam rau ua, tab sis cia siab tias yuav raug nqi ntau dua.
Q5: Kuv puas tuaj yeem tau txais C70600 raj nrog metric OD es tsis txhob nti?
Yog lawm, metric OD qhov ntau thiab tsawg yog muaj los ntawm ntau lub zeb.Cov metric ODs: 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, 25mm, 30mm, 35mm, 40mm, 50mm. Txawm li cas los xij, qhov ntau thiab tsawg ntawm nti (1/2", 5/8", 3/4", 1 ") feem ntau khaws cia. Metric qhov ntau thiab tsawg yuav xav tau ntau lawm.
Q6: Dab tsi yog qhov txawv ntawm tube OD thiab tube ID?
OD yog sab nraud txoj kab uas hla. ID yog nyob rau hauv txoj kab uas hla (OD rho tawm 2 x phab ntsa thickness).Rau 3/4 "OD tube nrog BWG 18 phab ntsa (1.24mm), ID=19.05mm - (2 x 1.24mm)=16.57mm. Rau kev tsim hluav taws xob, OD tseem ceeb rau lub raj ntawv qhov. ID tseem ceeb rau qhov chaw ntws.
Q7: Kuv puas tuaj yeem tau txais C70600 raj ntev dua 6 meters?
Yog, mus txog 15 meters (49 ko taw) rau feem ntau ODs.Cov raj ntev dua tuaj yeem ua tau rau cov ODs me. Txawm li cas los xij, cov raj ntev dua yog qhov nyuaj rau nkoj. Txheem ntim haum 6m raj yooj yim. Cov raj tshaj 6m xav tau cov tsheb thauj khoom ntev dua lossis cov thawv tshwj xeeb. Rau feem ntau cov haujlwm, 6m yog tus qauv.
Q8: Dab tsi yog qhov ncaj siab kam rau ua rau C70600 raj?
ASTM B111 tsis qhia txog tus lej ncaj ncees kam rau ua. Kev lag luam xyaum yog 1.5mm ib 3 meters.Cov raj uas pom tau tias khoov tuaj yeem raug tso tseg. Rau cov hlua ntev nrog ntau daim hlau txhawb nqa, qhia txog qhov yuav tsum tau ua ncaj nraim ntawm koj PO. Mills tuaj yeem muab cov raj ncaj ncaj ntawm tus nqi ntxiv me ntsis.
Q9: Yuav ua li cas kuv xam lub raj qhov hnyav ib 'meter'?
Luj (kg/m)=(OD² - ID²) x π/4 x density ÷ 1,000,000.OD thiab ID hauv mm, ceev=8.94 g/cm³. Ib txoj hauv kev yooj yim dua: siv daim ntawv qhia qhov hnyav saum toj no lossis nug koj tus neeg muag khoom rau lub ntsuas qhov hnyav. Rau kev kwv yees ntxhib, C70600 raj hnyav txog 8.94 x phab ntsa x (OD - phab ntsa) x π / 1,000,000 hauv kg ib 'meter'.
Q10: Dab tsi yog qhov tsawg kawg nkaus phab ntsa thickness rau C70600 raj hauv qab ASTM B111?
BWG 22 (0.71mm) yog cov phab ntsa nyias nyias.Qee lub mills tuaj yeem ua thinner los ntawm kev pom zoo tshwj xeeb, tab sis BWG 22 yog qhov ua tau tsawg kawg nkaus. Cov phab ntsa nyias nyias yog qhov nyuaj rau kos yam tsis muaj tearing thiab muab kev tiv thaiv corrosion me me. Feem ntau cov engineers tsis qhia hauv qab BWG 20 (0.89mm).
Q11: Kuv puas tuaj yeem xaj C70600 raj hauv qhov ntev tsis txhob txiav qhov ntev?
Yog, random ntev feem ntau yog 5 mus rau 7 meters (16 mus rau 23 ko taw).Random ntev raug nqi tsawg dua qhov txiav ntev vim tias lub zeb tsis tas yuav txiav kom meej. Txawm li cas los xij, koj yuav tau txais cov raj ntawm qhov ntev sib txawv hauv qhov ntau. Rau cov tshav kub exchanger bundles, kev txiav ntev yog pom zoo. Rau Tshuag, random ntev yog zoo.
