Chitoliro cha pampu yotentha ya PE yochokera pansi

1. Kukhazikitsa soketi yosungunuka ndi kutentha. Njirayi imagwiritsidwa ntchito kwambiri pa ma DN20-DN110mm. Njira yeniyeni yogwirira ntchito ndi iyi:

(1) Gwiritsani ntchito zodulira mapaipi kuti mudule chitolirocho malinga ndi zosowa za kukhazikitsa;

(2) Lembani kuya kwa chitoliro chomwe chiyenera kuyikidwa;

(3) Tenthetsani chosungunula chotentha kufika pa 210℃

(4) Tenthetsani mapaipi ndi zolumikizira nthawi imodzi, kenako ikani ma socket (dikirani kwakanthawi socket ikayikidwa pamalo ake ndikusiya. Musasunthe panthawi yotenthetsera, kuyika ma socket ndi kuziziritsa)

(5) Zozizira mwachilengedwe:

(6) Ntchito yomanga ikatha, chitolirocho chikhoza kutsekedwa ndikugwiritsidwa ntchito pokhapokha mutapambana mayeso a kuthamanga kwa mpweya.

2. Kukhazikitsa matako otentha, DN160-DN1200mm nthawi zambiri amagwiritsa ntchito njira iyi, ntchito zotsatirazi:

(1) Ikani mapaipi awiri a PE kuti alumikizidwe pa chotenthetsera chosungunuka nthawi imodzi (cholumikizira chingasinthidwe malinga ndi kukula kwa chitoliro chomwe chikuyikidwa), ndikukweza mbali ina ya chitoliro chilichonse pamwamba pa madzi omwewo ndi bulaketi ya chitoliro;

(2) Gwiritsani ntchito chodulira chamagetsi kuti mudule mbali zonse za mapaipi kuti muwonetsetse kuti malo olumikizirana a mapaipi awiriwa akugwirizana bwino.

(3) Kwezani mbale yotenthetsera yamagetsi kufika madigiri 210, ikani pakati pa malekezero awiri a mapaipi, ndikugwiritsa ntchito chipangizo chamagetsi cha hydraulic kuti malekezero awiri a mapaipiwo agwirizane kwathunthu ndikutenthetsa ndi mbale yotenthetsera yamagetsi nthawi imodzi;

(4) Chotsani mbale yotenthetsera ndikugwiritsanso ntchito chipangizo cha hydraulic kuti malekezero awiri a mapaipi osungunuka azungulire bwino ndikutseka chipangizo cha hydraulic (kuti chisabwererenso);

(5) Sungani kwa nthawi inayake yozizira ndikuyimasula, ndipo ntchitoyo yatha;

(6) Ntchito yomanga ikatha, iyenera kuvomerezedwa ndi mayeso okakamiza isanaikidwe pansi ndikugwiritsidwa ntchito; (Dziwani: Mayeso okakamiza ayenera kukhala mayeso okakamiza amadzimadzi!)

(7) Chitani zinthu zoteteza mphepo panthawi yotenthetsera chitoliro, ndipo panthawi yoziziritsa, chitolirocho chiyenera kuziziritsidwa pang'onopang'ono m'malo mofulumira.

3. Kulumikizana kwa magetsi (m'mimba mwake wa chitoliro dn≤630mm):

(1) Ikani chitoliro cha PE kwathunthu mu cholumikizira chamagetsi cha fusion payipi;

(2) Lumikizani mawaya awiri a makina apadera olumikizira magetsi ku mitengo yabwino ndi yoyipa ya chitoliro cholumikizira magetsi motsatana;

(3) Yatsani magetsi kuti mutenthe waya wotenthetsera kuti musungunule PE pa cholumikizira chamkati;

(4) Pambuyo pozizira:

(5) Ntchito yomanga ikatha, iyenera kuvomereza mayeso okakamiza isanatsekedwe ndikugwiritsidwa ntchito.

4. Kulumikizana kwa Flange

5. Kulumikiza mphika ndi pulasitiki

6. Kukhazikitsa malo oimikapo chitoliro chooneka ngati chishalo, komwe kumathandiza kwambiri kuthetsa vuto la kupotoza chitoliro chachikulu
