Vuam txheej txheem ntawm electrofusion socket fittings

1 Kev npaj ua ntej welding 1. Xyuas cov welding input voltage specifications. Nws yog nruj me ntsis txwv tsis pub txuas rau lwm theem ntawm qhov hluav taws xob los tiv thaiv lub tshuab vuam los ntawm kev kub hnyiab los yog ua tsis tiav.
2. Xaiv txoj hlua hluav taws xob kom raug raws li lub zog tiag tiag ntawm cov khoom siv.
3. Ntsuas qhov hluav taws xob qhov hluav taws xob kom paub meej tias qhov hluav taws xob ua tau raws li qhov yuav tsum tau ua thaum lub tshuab vuam ua haujlwm.
4. Ntxuav lub hwj chim tso zis connector kom ntseeg tau zoo conductivity. 1. Ua ntej vuam, xyuas seb qhov vuam voltage, lub sij hawm thiab lwm yam melting tsis yog raws li cov electrofusion yeeb nkab fittings.
2. Kev Ntsuas: Ntsuas qhov ntev lossis qhov nruab nrab ntawm cov yeeb nkab electrofusion, thiab kos cov welded yeeb nkab nto nrog ib kab.
3. Txiav cov yeeb nkab. Qhov hla ntawm cov yeeb nkab yuav tsum yog perpendicular mus rau axis, thiab qhov yuam kev yuav tsum yog<5mm.
4. Ntxuav qhov vuam nto. Scrape qhov chaw vuam nyob rau hauv qhov chaw cim txog 0.1-0.2 hli tuab kom tshem tawm cov txheej oxide. Qhov chaw scraping yuav tsum loj tshaj qhov ntug ntawm lub qhov (socket) yeeb nkab haum.
5. Qhov (socketing) ntawm cov kav dej thiab fittings. Rov kos cov yeeb nkab ntawm ib nrab ntawm qhov ntev ntawm ntu. Lub qhov (socket) huv electrofusion yeeb nkab haum nrog cov yeeb nkab yuav tsum tau welded, ua kom lub ntug sab nrauv ntawm cov yeeb nkab haum dej nrog cov kab cim. Qhov tsis sib haum xeeb ntawm cov kav dej thiab cov fittings yuav tsum tsawg dua 2 feem pua.
6. Cov yeeb nkab haum installation. Siv cov lus qhia los ntawm cov chaw tsim khoom siv yeeb nkab kom ntseeg tau tias tsis muaj qhov sib txawv ntawm ob qhov chaw vuam ntawm cov yeeb nkab haum thiab cov yeeb nkab.
7 Vuam pib lub vuam hloov thiab teem lub sij hawm vuam raws li lub sij hawm teev nyob rau hauv cov yeeb nkab haum khoom phau ntawv. 1. Kev sib txuas ntawm lub vuam ntsaws thiab cov yeeb nkab electrofusion haum yuav tsum ruaj thiab yuav tsum tsis txhob xoob.
8 Lub ntuj txias Lub sijhawm txias yuav tsum tau txiav txim siab raws li cov lus qhia ntawm cov yeeb nkab fittings. Thaum lub sijhawm ua kom txias, tsis muaj kev quab yuam sab nraud yuav tsum tau siv rau qhov chaw welded.
