C. Kev tshuaj xyuas qhov tsos

D. Kev tsim cov txheej txheem tom ntej

2. Kev npaj ua ntej kev tsim kho 

1). Kev npaj cov duab kos duab:

Kev tsim kho raws li cov duab kos uas yuav tsum ua. Thaum lub chaw tsim qauv muaj daim duab kos zoo, lub chaw tsim kho yuav tsum mus rau qhov chaw tsim kho kom nkag siab txog qhov xwm txheej tshwj xeeb. Rau qhov uas tsis tuaj yeem tsim kho raws li daim duab kos, nws yuav tsum qhia thiab sib tham nrog lub chaw tsim qauv kom txiav txim siab seb puas siv tau cov thev naus laus zis tshwj xeeb lossis kev hloov pauv tsim qauv hauv zos. Tib lub sijhawm, cov ntaub ntawv thiab cov khoom siv yuav tsum tau yuav raws li cov duab kos, thiab yuav tsum npaj cov sijhawm tsim kho.

2). Kev cob qhia cov neeg ua haujlwm:

Cov neeg ua haujlwm koom nrog kev sib txuas cov kav dej roj polyethylene yuav tsum tau txais kev cob qhia tshwj xeeb ua ntej yuav ua haujlwm, thiab tsuas yog tuaj yeem ua haujlwm tom qab dhau qhov kev xeem thiab kev ntsuam xyuas kev txawj ntse.

Ntxiv rau qhov kev paub txog kev paub txog roj, cov yam ntxwv ntawm cov ntaub ntawv tshwj xeeb polyethylene, kev paub txog hluav taws xob, cov khoom siv vuam polyethylene, kev tsim kho tshuab polyethylene roj pipeline thiab lwm yam ntawm cov neeg ua haujlwm cob qhia, thiab koom nrog kev ntsuam xyuas.

3). Kev npaj cov tshuab thiab cov cuab yeej siv

Raws li qhov yuav tsum tau ua ntawm kev siv tshuab tsim kho, npaj cov tshuab thiab cov cuab yeej tsim kho kom haum. Vim tias tsis muaj tus qauv sib koom ua ke rau qhov zoo ntawm kev vuam thiab cov txheej txheem vuam ntawm cov yeeb nkab polyethylene hauv peb lub tebchaws, cov txheej txheem vuam ntawm cov yeeb nkab, cov yeeb nkab fittings thiab PE pob valve tsim los ntawm cov chaw tsim khoom sib txawv yog txawv. Yuav kom ua tiav cov txiaj ntsig vuam txhim khu kev qha, thaum xaiv cov khoom siv yuav tsum tau xaiv kom zoo, xaiv cov khoom zoo, hauv cov txiaj ntsig vuam, kom ntseeg tau.

a) Tshuab vuam electrofusion tsis siv neeg

b) 30Kw diesel generator

c) Kho qhov khoom siv

d) Tig lub scraper

e) Lub tshuab khawb phaj

f) Clamping cuab yeej

g) Tig lub tshuab txiav

h) Tus kav tiaj tiaj

i) Cov Cim Cim

 

3. Kev lees txais cov yeeb nkab, cov khoom siv thiab PE pob valve 

1) Xyuas seb cov khoom puas muaj daim ntawv pov thawj Hoobkas thiab daim ntawv tshuaj xyuas Hoobkas.

2) Tshawb xyuas qhov tsos. Tshawb xyuas seb sab hauv thiab sab nraud ntawm cov yeeb nkab puas huv thiab du, thiab seb puas muaj cov grooves, cov duab kos, cov dents, cov khoom tsis huv thiab cov xim tsis sib xws.

3) Kev kuaj xyuas qhov ntev. Qhov ntev ntawm lub raj yuav tsum sib npaug thiab qhov yuam kev yuav tsum tsis pub tshaj qhov ntxiv lossis rho tawm 20 hli. Xyuas seb qhov kawg ntawm lub raj puas yog perpendicular rau lub axis ntawm lub raj ib qho los ntawm ib qho, thiab seb puas muaj qhov hws. Cov kav dej ntawm qhov ntev sib txawv yuav tsum tsis txhob raug lees txais ua ntej qhov ua rau raug txheeb xyuas.

4) Cov yeeb nkab Polyethylene rau kev siv roj yuav tsum yog xim daj thiab dub, thaum nws yog xim dub, lub qhov ncauj yeeb nkab yuav tsum muaj ib daim kab xim daj uas ntxim nyiam, tib lub sijhawm, yuav tsum muaj cov cim tas mus li nrog qhov deb tsis pub tshaj 2m, qhia txog lub hom phiaj, qib khoom siv raw, qhov sib piv ntawm qhov loj me, qhov loj me, tus lej txheem thiab tus lej serial, lub npe chaw tsim khoom lossis lub cim lag luam, hnub tsim khoom.

5) kev kuaj xyuas qhov puag ncig: Qhov nruab nrab ntawm cov txiaj ntsig ntawm kev xeem ntawm peb qhov qauv raug coj los ua qhov puag ncig ntawm cov yeeb nkab, thiab nws tus nqi ntau dua 5% raug suav tias tsis tsim nyog.

6) Xyuas seb lub yeeb nkab txoj kab uas hla thiab qhov tuab ntawm ob lub yeeb nkab yog dab tsi. Yuav tsum siv tus pas ntsuas ncig los xyuas seb lub yeeb nkab txoj kab uas hla yog dab tsi, thiab yuav tsum ntsuas seb ob lub yeeb nkab txoj kab uas hla yog dab tsi. Yog tias tsis muaj qhov chaw uas tsim nyog, yuav raug suav hais tias tsis tsim nyog.

Kev tshuaj xyuas qhov tuab ntawm phab ntsa yog nqa tawm nrog lub micrometer, ntsuas qhov ncig ntawm plaub lub ntsiab lus sab saud thiab qis, ib qho twg tsis tsim nyog.

7) Yeeb nkab, cov khoom siv yeeb nkab, PE pob valve kev thauj mus los thiab cia khoom

Kev thauj mus los thiab kev khaws cia cov khoom polyethylene yuav tsum tau ua raws li cov hauv qab no: Cov hlua uas tsis yog hlau yuav tsum tau siv rau kev khi thiab kev tsa.

8) Yuav tsum tsis txhob pov thiab los ntawm kev cuam tshuam hnyav, yuav tsum tsis txhob rub.

Yuav tsum tsis txhob raug tshav ntuj, nag, thiab roj, kua qaub, alkali, ntsev, cov neeg sawv cev thiab lwm yam tshuaj lom neeg sib cuag.

9) Cov yeeb nkab, cov khoom siv, PE pob valve yuav tsum khaws cia rau hauv qhov chaw muaj cua zoo, qhov kub thiab txias tsis pub tshaj 40 ℃, tsis pub tsawg dua -5 ℃ hauv tsev rau khoom, thiab kev teeb tsa ib ntus hauv qhov chaw tsim kho yuav tsum tau npog.

10) Thaum lub sijhawm thauj mus los thiab khaws cia, lub raj me me tuaj yeem ntxig rau hauv lub raj loj.

11) Kev thauj mus los thiab cia khoom yuav tsum tau muab tso rau hauv av tiaj tus thiab chav nres tsheb kab rov tav. Thaum tsis zoo li qub, yuav tsum tau teeb tsa cov kev txhawb nqa tiaj tus, qhov sib nrug ntawm cov kev txhawb nqa yog 1-1.5m, thiab qhov siab ntawm cov yeeb nkab yuav tsum tsis pub tshaj 1.5m.

12) Nws tau hais tias lub sijhawm khaws cia ntawm kev tsim khoom thiab kev siv yuav tsum tsis pub tshaj 2 xyoos, thiab yuav tsum ua raws li txoj cai ntawm "thawj zaug nkag, thawj zaug tawm" thaum faib cov ntaub ntawv.

4Cov kauj ruam txuas ntawm electrokev sib txuas ua ke  

1). Txuas lub hwj chim ntawm txhua qhov ntawm lub welder. Yuav tsum siv 220V, 50Hz AC, qhov hloov pauv voltage hauv ± 10%, lub hwj chim yuav tsum yog grounded xaim; Npaj cov cuab yeej pab xws li marker, flat scraper, flat ruler, thiab fixture.

2) Npaj cov kav dej thiab cov khoom siv uas yuav tsum tau vuam, thiab tsis txhob qhib lub ntim ntawm cov khoom siv vuam thaum ntxov dhau.

3) Peb qhov kev teeb tsa: tshem tawm cov pob khoom sab nraud ntawm cov yeeb nkab fittings, cov yeeb nkab fittings sau npe rau hauv cov yeeb nkab fittings kom tau welded ua qhov chaw teeb tsa cim; Nruab qhov kho khoom siv thiab kho qhov sib dhos kom tau welded nrog rooj tog; Qhib lub tsho electrode ntawm cov yeeb nkab fitting thiab nruab cov electrode tso zis ntawm lub tshuab hluav taws xob fusion welder rau ntawm cov yeeb nkab fitting electrode.

4) Siv lub tshuab vuam raws li cov txheej txheem ua haujlwm mus rau qhov chaw ntawm cov txheej txheem vuam, manually (cov txheej txheem muab los ntawm daim ntawv lo rau cov yeeb nkab)

5) Pib lub tshuab vuam fais fab fusion kom pib cov txheej txheem vuam, thiab lub tshuab yuav ntes tau qhov kub thiab txias ntawm ib puag ncig thiab kho cov kev teeb tsa vuam. Tom qab cov txheej txheem vuam tiav lawm, lub tshuab yuav nres lub sijhawm vuam thiab txias. Tom qab txias tiav lawm, lub electrode thiab cov khoom siv ruaj khov tuaj yeem tshem tawm rau ntu tom ntej kom vuam.

6) Luam cov ntaub ntawv teev cov txheej txheem vuam lossis tom qab ntawd luam tawm hauv nruab nrab.

 

5. Cov txheej txheem vuam 

Siv lub tshuab vuam raws li cov txheej txheem. Cov kev teeb tsa tau muab los ntawm daim ntawv lo rau cov yeeb nkab.

6. Kev kuaj xyuas zoo ntawm hluav taws xobofusion khub interface

1) Kev tshuaj xyuas qhov zoo ntawm qhov vuam: Txoj kev tshuaj xyuas: kev tshuaj xyuas pom; Ib tus pas ntsuas raug ntsuas.

2) Tshawb xyuas cov khoom: concentricity; Saib xyuas cov khoom siv overflow ntawm lub qhov.

3) Cov qauv tsim nyog: qhov qhib txhaum tsawg dua 10% ntawm cov yeeb nkab phab ntsa tuab; Cov yeeb nkab sib xyaw ua ke nruj nreem nrog cov yeeb nkab thiab sib xws; Cov txheej txheem vuam tsis muaj kev haus luam yeeb (overheating), qhov xwm txheej kaw ua ntej lub sijhawm; Lub qhov soj ntsuam ntawm cov khoom siv fuse tawm ntawm cov khoom siv. Ua tau raws li cov xwm txheej saum toj no tuaj yeem txiav txim siab tias tsim nyog.

7.Kev ntsuas kev nyab xeeb 

1) Cov neeg ua haujlwm yuav tsum hnav khaub ncaws zoo: hnav hnab looj tes tiv thaiv; Hnav khau ua haujlwm; Hnav tsom iav tiv thaiv; (thaum sib tsoo cov khoom ua haujlwm): nrog lub pob ntseg tiv thaiv, lub kaus mom vuam.

2) Cov khoom siv ruaj khov hauv av, hloov pauv tiv thaiv kev xau.
