Mafunso ndi Mayankho Ofala Okhudza Valavu Yothira Mafuta ya Zipangizo Zodzaza Mafuta za MV ndi HV Transformer

​

Q1: Kodi njira zodzitetezera pakugwiritsa ntchito ndi kusamaliravalavu?
A1: Malangizo ogwiritsira ntchito:
1. Kuyang'ana musanalumikize: Musanayambe kugwira ntchito, yang'anani ngati zipewa zoteteza pa ma valve interfaces zili bwino, ndipo tsimikizirani kuti ma interfaces ndi malo otsekera sakuwonongeka ndipo alibe zinthu zakunja.
2. Kulumikiza koyenera: Gwiritsani ntchito zida zoyenera (monga cholumikizira cha torque) kuti mulimbikitse kulumikizana ndi mpando wa valavu ya transformer ndi mapaipi a zida zakunja malinga ndi torque yoyenera, kuonetsetsa kuti nkhope yakumapeto imatsekedwa bwino komanso kupewa kulimbitsa kwambiri kapena kuletsa kulimbitsa.
3. Konzani kutsegula ndi kutseka bwino: Mukatsegula kapena kutseka valavu, tembenuzani gudumu lamanja bwino. Musagwiritse ntchito zida monga mipiringidzo yowonjezera kuti mugwiritse ntchito mwamphamvu kuti mupewe kuwonongeka kwa tsinde la valavu kapena pamwamba pake potseka. Mukatsegula kwathunthu, tikukulimbikitsani kutembenuza gudumu lamanja pang'ono kuti muteteze ulusi.
4. Kutsimikizira momwe zinthu zilili: Mukamaliza kugwira ntchito, tsimikizirani momveka bwino momwe valavu ilili ngati "yotseguka kwathunthu" kapena "yotsekedwa kwathunthu" pogwiritsa ntchito malo a chiwongolero cha dzanja kapena zizindikiro zosonyeza. Mitundu ina ili ndi zida zotsekera, zomwe ziyenera kutsekedwa m'malo ofunikira.
Malangizo Osamalira:
Kuyang'ana pafupipafupi: Musanayambe kukonza transformer kapena kukonza mafuta, yang'anani kunja kwa valavuyo kuti muwone ngati pali zizindikiro zilizonse za kutuluka, kuwonongeka, kapena dzimbiri.
Mayeso a ntchito: Ngati zinthu zilola, mayeso osavuta otsekera amatha kuchitika limodzi ndi kulumikizana kwa zida (monga kuwona kukhazikika kwa vacuum pambuyo polumikizana ndi kutsuka vacuum).
Kusintha chisindikizo: Ngati ntchito yotseka yachepa pambuyo pogwiritsa ntchito kwa nthawi yayitali (monga kutulutsa mafuta pang'ono pa tsinde la valavu), akatswiri ayenera kusintha choyikapo kapena mphete za O pogwiritsa ntchito phukusi loyambirira la zida zosinthira. Anthu omwe si akatswiri sayenera kusokoneza magawo apakati a valavu okha.
Q2: Momwe mungasankhire yoyeneravalavu yotulutsira mafutaza ma transformer ndi zida zodzaza mafuta zamitundu yosiyanasiyana?
A2: Kusankha kuyenera kuganizira magawo ofunikira ofananira:
1. M'mimba mwake ndi njira yolumikizira: Dziwani kukula kwa doko la valavu kutengera kukula kwa malo osungira mpando wa valavu wa thanki yamafuta a transformer (monga DN25, DN40, DN50, ndi zina zotero) ndi mawonekedwe olumikizira (monga flange standard PN16/DN40, ulusi wa British NPT, ndi zina zotero) kuti muwonetsetse kulumikizana kwenikweni.
2. Kupanikizika ndi mulingo wa vacuum: Tsimikizirani kuti kupanikizika kwa kapangidwe ka vacuum ndi mulingo wa vacuum wa valavu zikukwaniritsa kapena kupitirira mphamvu yayikulu yogwira ntchito komanso mulingo wapamwamba kwambiri wa vacuum wofunikira ndi zida zodzaza mafuta (monga vacuum pump, mafuta pump) ndi ukadaulo wopangira transformer.
3. Kugwirizana kwa mafuta oteteza: Tsimikizani kuti zinthu zonse zotsekera ndi zinthu zomwe zakhudzana ndi mafuta a valavu zimagwirizana kwathunthu ndi mtundu wa mafuta oteteza omwe mumagwiritsa ntchito (monga mafuta amchere, mafuta a silicone, ester yopangidwa).
Malo ogwirira ntchito: Ganizirani ngati ndi malo achikhalidwe amkati/kunja kapena ali ndi zofunikira zapadera (monga kuzizira kwambiri, kutentha kwambiri, kupopera mchere, ndi zina zotero) kuti mudziwe ngati zipangizo zapadera za chipolopolo kapena mankhwala pamwamba pake akufunikira.
Q3: Kodi mungatsimikizire bwanji ndikutsimikizira kuti ma valve ndi abwino komanso odalirika?
A3: Timatsimikiza mtundu wa valavu iliyonse kudzera munjira zokhwima zopangira ndi kuyesa:
Kuyesa kulimba kwa mpweya: Pamene valavu yatsekedwa, mpweya wouma komanso woyera (monga mpweya kapena nayitrogeni) umadzazidwa mu valavu pa mphamvu inayake. Kupanikizika kumasungidwa kuti kuwone ngati pali kutayikira kulikonse, kutsimikizira momwe ikutsekerera pansi pa mphamvu yabwino.
Kuyesa kutseka vacuum: Malekezero amodzi a valavu amatsekedwa, ndipo malekezero ena amalumikizidwa ndi pampu ya vacuum. Imachotsedwa ku mulingo wapamwamba wa vacuum (monga pansi pa 10 Pa), ndipo kuchuluka kwa kutsika kwa vacuum kumayesedwa mkati mwa nthawi inayake kuti zitsimikizire momwe imagwirira ntchito yotseka pansi pa vacuum yapamwamba.
Mayeso a Mtundu: Kuyesa zitsanzo nthawi zonse kumachitika kuti pakhale mayeso ozama a moyo (monga mayeso otsegulira ndi kutseka), mayeso a kutentha kwambiri komanso kotsika, komanso mayeso ogwirizana ndi mafuta oteteza kutentha, ndi zina zotero, kuti atsimikizire kudalirika kwa kapangidwe kake kwa nthawi yayitali.
