Short Stab, Yuam Kev, thiab Qhov Tob Koj Nkag: Cov Yuam Kev Geometry Uas Ua Rau Ntws Dej

Insertion yog qhov yooj yim tshaj plaws ntawm tag nrho txheej txheem, tab sis kuj yog qhov yooj yim tshaj plaws uas yuav ua tsis tau zoo thaum hnub phem: txhais tes txias, ib lub raj uas tsis txav, ib qho joint hauv qab trench, lossis ib pab neeg khiav ceev kom ua tiav lub sijhawm rov puv. Lub unit yuav tsis pom ib qho ntawm lawv. Ib qho fitting welded rau ib lub raj uas luv 5 mm ntawm qhov nres zoo li ib qho txuas zoo los ntawm sab nraud.

Qhov tob ntawm insertion tiag tiag yog dab tsi

Fusion zone yog qhov seem ntawm heating coil sab hauv fitting. Nws pib me ntsis los ntawm qhov ncauj thiab xaus ua ntej qhov chaw nres nruab nrab. Yuav kom joint tsim tau zoo, phab ntsa raj yuav tsum nyob hauv qab tag nrho thaj chaw ntawd, nrog cov khoom huv, scraped ob sab. Yog qhov tob tsis raug, peb qhov teeb meem yuav tshwm sim:

• Short stab- lub raj tsis nkag mus tob txaus. Sab nraud kawg ntawm coil tsis muaj dab tsi yuav yaj rau, thiab qhov ntev txuas tau txo. Thaum coupling, ib nrab ntawm joint tej zaum yuav nqa qhov hnyav.
• Mis-stab- kav mus rau hauv ntawm ib lub kaum sab xis. Ib sab kov coil, lwm sab tso qhov khoob; coil yuav raug thawb los yog puas thaum kav nkag mus.
• Ntxiv dhau ces rub rov qab- kav raug rub rov qab kom phim nrog qhov ntev tom ntej, tso qhov khoob ntawm stop uas tsis muaj leej twg xyuas.

Cim qhov tob, tsis txhob twv

Txhua qhov fitting muaj qhov tob rau insertion, thiab kav yuav tsum tau cim ntawm qhov tob ntawd ntxiv rau margin pom ua ntej sib dhos. Cim ua ob yam: nws qhia rau jointer thaum kav nyob rau qhov chaw, thiab nws muab tus neeg soj xyuas ib yam los xyuas tom qab txuas tau ua tiav. Qhov cim yuav tsum nyob sab nraud ntawm qhov ncauj txuas, sib npaug ib ncig ntawm lub raj. Yog ib sab ntawm lub cim nyob sab hauv thiab sab lwm sab tawm 10 mm, lub raj yog cocked thiab qhov txuas tsis txhob welded.

Tsib yam ua rau

Ua rau	Paub meej
Qhov kawg ntawm lub raj tsis txiav square	Ib qho txiav txiav ua rau muaj ib qho bevel; ib sab kov qhov nres thaum lwm sab tseem luv. Siv lub cutter raj lossis ib lub jig txiav square.
Burr lossis swarf ntawm qhov kawg ntawm lub raj	Burrs rub cov khoom tawm ntawm qhov txuas thiab ua rau lub raj luv. Tshem burr ua ntej tso rau.
Lub raj oval	Ib qho oval kawg raug nres hauv qhov bore. Ua kom nws puag ua ntej.
Qhov txuas tsis sib haum nrog lub raj axis	Nias ntawm ib qho kaum sab ua rau lub raj tsav mus rau ib sab ntawm lub qhov dej.
Kev txav tom qab tso	Lub clamp, qhov hnyav ntawm lub raj, lossis ib lub raj thib ob txav tiv thaiv thawj lub raj tuaj yeem txav qhov txuas ua ntej lossis thaum lub voj voog.

Kev txwv yog ib feem ntawm kev tso

Kev tso tsis ua thaum lub raj kov rau qhov nres; nws ua thaum lub rooj sib dhos tsis txav tau ntxiv lawm. Ib qho coupling ntawm lub raj uas muaj qee qhov puab tuaj yeem txav mus rau hauv lub raj: lub zog khaws cia hauv lub raj txav lub fitting mus rau ntawm lub raj lossis tig nws thaum cov khoom kub tawg. Kho qhov no raws li tshuab: txhawb lub raj ob sab, siv alignment clamps ze rau qhov txuas, thiab cia lawv nyob rau lub sijhawm txias tag nrho. Ntawm ib qho slope, txhawb nqa sab nqes kom lub raj qhov hnyav tsis txhob ua rau qhov txuas raug kev ntxhov siab.

Saddles thiab tees xav tau kev saib xyuas zoo ib yam

Rau saddle, tej yam yuam kev muaj xws li saddle tawm ntawm kab nruab nrab uas tau cim, qhov outlet uas tsis perpendicular rau main, lossis tso underclamp ua ntej dhau. Rau tee lossis ceg ntoo, kev pheej hmoo yog angular: ceg ntoo tuaj yeem rub kom phim nrog yeeb nkab thaum kub, uas ua rau fusion zone muaj kev ntxhov siab. Tso ceg ntoo ua ntej welding, lossis lees txais tias qhov txuas yuav raug kev ntxhov siab txij hnub ib.

FAQs

Kuv yuav paub li cas tias kav yeeb nkab twb nyob hauv tag nrho lawm?

Xyuas qhov tob cim ncig tag nrho circumference, tsis yog los ntawm kev hnov. Yog koj tsis pom cim, koj tsis tuaj yeem paub tseeb qhov tob.

Puas yog qhov txuas luv uas raug kho dua los ntawm weld dua?

Tsis tau. Lub coil twb kub lawm thiab qhov ntev uas txuas tau ruaj khov lawm. Txhob ua li ntawd.

Puas yog muaj qhov me me ntawm qhov chaw nres tau?

Tsuas yog yog tus tsim khoom fittings tso cai xwb. Ob qhov kawg yeeb nkab uas tsis sib txuas ua ke, ua rau muaj ib thaj chaw yaj tsis muaj kev txhawb nqa nyob hauv nruab nrab, uas yog ib qho teeb meem zais.

Kuv puas yuav tsum muaj clamps rau cov yeeb nkab me?

Yog lawm. Cov raj me me yog qhov yooj yim tshaj plaws los txav thiab nyuaj tshaj plaws los kuaj. Cov clamps kuj puag rov qab, yog li lawv tshwm sim hauv txhua txoj kev luam tawm, tsis hais qhov loj.
