2024 Tus sau: Stanley Ellington | [email protected]. Kawg hloov kho: 2023-12-16 00:17
Cov mis rau xam qhov tsim ntev ntawm a khoov yog: Developed length (DL) yog sib npaug rau lub centerline radius (R) ntawm lub khoov lub sij hawm lub kaum sab xis (A) ntawm khoov ua 0,01745. Qhov ntev tsim rau 90 degree khoov nrog 40 "radius yog 90 x 40 x 0.01745 = 62.82".
Ib yam li ib tug yuav nug, dab tsi yog cov qauv rau concentric khoov?
Qhov tsim ntev (DL) yog sib npaug rau qhov nruab nrab lub vojvoog ntawm lub khoov lub sij hawm lub kaum sab xis ntawm lub khoov x 0.0175 ib. Conduit 1: DL = 20 x 90 x 0.0175. dl = 31.5 . Rau Conduit 2: DL = 24.375 x 90 x 0.0175.
Tsis tas li ntawd, ua li cas koj khoov tubing ntawm 180 degrees? Ua kom tiav a 180 ° kaum, ua ntej khoov 90 ° ces viav vias luv luv los siv qhov kev ua haujlwm ceev kom txog thaum nws yog me ntsis saum toj perpendicular rau tus kov ntev. Khoov maj mam kom txog rau thaum 0 ° cim ntawm qib ntsuas tau kab nrog kab 180 ° cim rau ntawm lub bender tuag.
Tom qab ntawd, ib tus tseem tuaj yeem nug, yuav ua li cas khoov cov nyiaj tau los?
Txhua tus qauv siv cov yuam sij hauv qab no:
- Lf = pav ca ntev ntawm daim ntawv.
- BA = khoov pob.
- BD = khoov qhov txiav tawm.
- R = sab hauv khoov vojvoog.
- K = K-factor, uas yog t / T.
- T = khoom thickness.
- t = nrug deb ntawm sab ntsej muag mus rau kab nruab nrab.
- A = khoov lub kaum sab xis nyob rau hauv degrees (lub kaum sab xis ntawm cov khoom yog khoov)
Yuav ua li cas khoov concentric offsets?
Yooj Yim: Qhov kev ncua deb txav ib txoj kab sib txuas rau lwm qhov yog tangent ntawm 1/2 ntawm lub kaum sab xis uas siv rau khoov tus offset lub sij hawm nruab nrab rau nruab nrab qhov nruab nrab ntawm cov kab ke. Hauv qhov piv txwv no, rau offsets khoov siv 30º lub kaum sab xis, qhov nrug yog sib npaug rau qhov tangent ntawm 15º lub sijhawm 2 ", lossis. 27 x 2 =. 54".

Koj xam xam cov nyiaj hli sib kis li cas?
Rho tawm qhov tsawg kawg ntawm qhov siab tshaj plaws. Qhov no yog qhov ntau. Hauv qhov piv txwv, 500,000 rho 350,000 sib npaug 150,000. Faib qhov ntau los ntawm qhov tsawg kawg kom pom qhov sib kis
Koj xam xam tag nrho cov neeg yuav khoom li cas?
Hloov chaw, tag nrho cov kev yuav khoom yuav tsum raug xam los ntawm kev ntxiv cov khoom muag kawg rau tus nqi ntawm cov khoom muag thiab rho tawm cov khoom pib pib. Feem ntau cov tuam txhab yuav muaj cov ntaub ntawv khaws tseg ntawm kev yuav khoom, yog li qhov kev suav no yuav tsis xav tau

Tuav qhov kawg ntawm cov yeeb nkab thiab rub nws ntawm koj kom khoov cov yeeb nkab tiv thaiv ntoo mandrel. Tuav cov yeeb nkab rau hauv qhov chaw rau 10 mus rau 15 vib nas this kom cov yeeb nkab txias me ntsis thiab tuav nws cov duab. Tshem cov yeeb nkab ntawm koj lub jig. Rov ua dua raws li xav tau kom txog thaum cov yeeb nkab yog khoov rau koj qhov kev xav tau
Yuav ua li cas koj xam lub raj khoov?
Kev xam cov tubing nyob rau hauv ib qho kev khoov yog yooj yim heev. Peb twb tau muab xam rau koj. Tsuas yog muab cov degrees koj tab tom khoov los ntawm cov lej hauv qab no thiab koj yuav tau txais qhov ntev ntawm lub raj hauv qhov khoov. Yog li yog tias koj khoov 90 degrees ntawm 6 "CLR tuag, koj lub raj hauv qhov khoov yog 90
