Cov yam ntxwv cuam tshuam rau qhov zoo ntawm PE electrofusion yeeb nkab fittings: Ua ntej, qhov cuam tshuam ntawm qhov hluav taws xob thiab qhov hloov pauv tam sim no ntawm qhov zoo ntawm qhov sib txuas. Rau qhov ua tau zoo tsim nyog electrofusion yeeb nkab fittings, tus nqi kuj ntawm cov hlau nyob rau hauv pre-resistance yog tas li; nws tsis tuaj yeem txuas ncaj qha rau lub tshuab hluav taws xob siab. Lub hwj huam mov rau vuam sib koom ib lub cable; Feem ntau, cov khoom siv hluav taws xob ntawm 2.5mm2 yog siv thaum lub tshuab vuam tsis pub dhau 50 meters ntawm lub hwj chim mov. Thaum lub tshuab vuam yog 50-100 meters deb ntawm lub hwj huam mov, yuav tsum xaiv 4mm2 input cable. Thaum lub vuam tshuab yog 100 meters deb ntawm lub hwj chim mov, lub input cable yuav tsum thickened los yog ib tug generator yuav tsum tau txuas nrog. Qhov cuam tshuam zoo ntawm electrofusion yeeb nkab fittings feem ntau yog raws li lub Hoobkas qauv ntawm electrofusion yeeb nkab fittings, thiab vuam lub sij hawm tsis yog feem ntau tsim raws li qhov kub thiab txias ntawm 20 degree. Yog hais tias qhov kub thiab txias sib txawv thaum lub sij hawm vuam, nws txhais tau hais tias cov cua kub conduction ntawm cov yeeb nkab fittings hloov thaum lub sij hawm vuam, uas ncaj qha cuam tshuam rau vuam zoo. Thaum kawg, qhov cuam tshuam ntawm kev ua haujlwm tsis raug ntawm qhov zoo ntawm kev sib txuas, cov yeeb nkab txuas qhov chaw nres nkoj tsis raug khawb lossis ua tiav zoo, cov yeeb nkab chaw nres nkoj tsis chamfered lossis muaj cov khib nyiab; qhov kev tso tawm tsis raug, cov yeeb nkab tau ntxig tob txaus - tsis txaus, cov yeeb nkab thiab cov yeeb nkab fittings tsis nyob rau tib axis Muaj kev ntxhov siab sab nraud; cov yeeb nkab coil tsis ncaj nraim ua ntej vuam, los yog cov yeeb nkab nrog loj dabtsi yog khoov deformation tsis tau sib npaug.
