Cov lus qhia rau kev siv hluav taws xob melting yeeb nkab fittings

Basic qauv ntawm hluav taws xob meltingcov yeeb nkab fittings.

Electric fusion vuam cuab yeej:

Hluav taws xob vuam tshuab, yeeb nkab txiav tshuab, scraper, sib tsoo tshuab, kav, cim cwj mem, extrusion vuam phom, yas vuam hlau (rau sealing)

Installation cov kauj ruam:

1. Kev npaj:

Txheeb xyuas tias cov khoom siv hluav taws xob nyob hauv thaj tsam xav tau los ntawm lub tshuab vuam, tshwj xeeb tshaj yog lub tshuab hluav taws xob.Xyuas seb lub peev xwm hlau puas ua tau raws li qhov yuav tsum tau muaj ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob thiab cov khoom siv hauv av.(Rau qhov Φ250mm txoj kab uas hla los yog tsawg duacov yeeb nkab fittings, lub zog ntawm lub tshuab fused yuav tsum loj dua 3.5KW;Rau Φ315mm lossis ntau dua cov yeeb nkab fittings, lub zog ntawm lub tshuab fused yuav tsum loj dua 9KW.Voltage thiab tam sim no yuav tsum nco ntsoov khaws cia rau hauv ± 0.5 ntau yam ntawm cov nqi teev).

2. Kev cuam tshuam ntawm cov kav dej:

Lub ntsej muag kawg ntawm cov yeeb nkab yuav tsum raug txiav perpendicular mus rau axis nrog qhov yuam kev tsawg dua 5 hli.Yog hais tias lub ntsej muag kawg ntawm cov yeeb nkab tsis yog perpendicular mus rau lub axis, nws yuav ua rau ib feem ntawm weld cheeb tsam yuav raug, ua rau vuam yuam kev xws li cov khoom molten ntws mus rau hauv cov yeeb nkab.Lub ntsej muag kawg ntawm cov yeeb nkab yuav tsum raug kaw tom qab cov yeeb nkab raug txiav.

3. Vuam nto tu:

Ntsuas thiab kos qhov tob lossis qhov chaw weld ntawm cov yeeb nkab nrog ib qho cim.Vim tias cov yeeb nkab polyethylene khaws cia rau ib lub sijhawm, cov oxide txheej yuav raug tsim rau ntawm qhov chaw.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau tshem tawm tag nrho cov txheej txheem oxide rau sab nrauv ntawm cov yeeb nkab thiab cov phab ntsa sab hauv ntawm cov yeeb nkab ua ntej vuam, uas yuav cuam tshuam rau vuam zoo thiab ua rau muaj kev nyab xeeb.Lub scraping ntawm vuam nto yuav tsum tau ib tug tob ntawm 0.1-0.2 hli.Tom qab scraping, ntxuav cov npoo thiab cov npoo ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab.

4. Qhov (socket) ntawm cov kav dej thiab fittings:

Lub tshuab ntxuav hluav taws xob melting yeeb nkab fittings yog muab tso rau hauv cov yeeb nkab yuav tsum tau welded, thiab sab nrauv ntawm cov yeeb nkab yog flush nrog cov cim kab.Thaum txhim kho, lub davhlau ya nyob twg ntawm cov yeeb nkab yuav tsum muab tso rau hauv txoj haujlwm yooj yim.Kev sib haum yuav tsum nyob rau hauv cov xwm txheej tsis muaj kev ntxhov siab nrog cov yeeb nkab rau kev teeb tsa ua ke.Kho qhov sib koom ua ke ntawm qhov haum thiab cov yeeb nkab mus rau tib lub concentricity thiab theem, thiab V puab tsis tuaj yeem tshwm sim ntawm cov yeeb nkab.Yog hais tias sab nraud txoj kab uas hla ntawm cov yeeb nkab yog loj heev, qhov saum npoo ntawm cov welded kawg ntawm cov yeeb nkab yuav tsum tau muab scraped dua kom ua tau zoo haum.Yog tias qhov haum thiab cov yeeb nkab loj dhau tom qab lub qhov (socket) tso, lub hoop yuav tsum tau dai kom nruj rau vuam.

5. Nruab lub centralizer:

Lub hauv paus tseem ceeb yuav tsum ua lub luag haujlwm nruj ntawm lub qhov (socket), kom paub tseeb tias nws tsis yooj yim txav thaum vuam;kev ua haujlwm ntawm qhov sib txawv ntawm cov yeeb nkab haum thiab cov yeeb nkab yog ua kom cov yeeb nkab tsis deformation.Kho ob lub nplhaib snap ntawm lub hauv nruab nrab mus rau txoj haujlwm zoo ntawm cov yeeb nkab, thiab nws yuav tsum nyob tom qab lub cim kom tsis txhob muaj cov yeeb nkab fittings nyob rau hauv qhov chaw, ceev lub snap nplhaib txiv ntseej ntawm lub centralizer, thiab clamp nws ntawm cov yeeb nkab.Ua tib zoo saib xyuas cov kev taw qhia ntawm cov ntsia hlau qhov ntawm lub hauv paus thaum lub sijhawm teeb tsa, tsam tsis tuaj yeem txhim kho cov ntsia hlau txoj cai.

6. Cov zis connector kev twb kev txuas:

Qhov kawg ntawm cov khoom siv vuam yog ruaj khov nrog cov yeeb nkab fittings.Yog tias qhov tso zis loj sib txawv ntawm cov yeeb nkab loj, yuav tsum siv tib qhov txuas txuas txuas.

7. Cov ntaub ntawv vuam:

Tom qab nkag mus rau qhov tseeb welding tsis, nias tus yuam sij Enter kom pib vuam.Thaum kawg ntawm cov txheej txheem vuam, lub tshuab vuam ceeb toom koj tau txais.Cov txheej txheem vuam raug kaw thaum lub sij hawm vuam los taug qab thiab txheeb xyuas qhov kev tsim kho zoo.Raws li qhov kub ntawm qhov chaw ib puag ncig thiab kev hloov ntawm kev ua haujlwm voltage, lub sijhawm vuam tuaj yeem raug them nyiaj zoo thaum lub vuam.Thaum qhov kub tsis tshua muaj, kev txuag hluav taws xob yuav tsum tau ua kom zoo rau vuam electrofusion yeeb nkab fittings.

8. Cua txias:

Thaum lub sijhawm vuam thiab lub sijhawm txias, cov khoom sib txuas tsis tuaj yeem txav los yog siv nrog lub zog sab nraud, thiab cov yeeb nkab yuav tsum tsis txhob raug ntsuas yog tias qhov txuas txuas tsis txaus txias (tsis pub tsawg dua 24 teev).
