Chiyambi cha Zamalonda - Valavu Yothira Mafuta Osinthira/Sampling Flange Valve

I. Chidule cha Zamalonda

Thengalande yotulutsira mafuta a transformer/valavu ya flange yoyesera zitsanzo ndi cholumikizira chapadera cha valavu chomwe chimayikidwa pansi kapena m'mbali mwa thanki yamagetsi yosinthira magetsi. Ntchito zake zazikulu ndikutulutsa mafuta oteteza transformer kapena kutulutsa zitsanzo za mafuta mosamala komanso moyenera, pamene akuonetsetsa kuti transformer ikugwira ntchito bwino kuti mafuta asatuluke komanso kuti mpweya ndi chinyezi zilowe.

Ndi gawo lofunika kwambiri pakukonza, kukonza, kuyesa mafuta, komanso kuthana ndi ngozi zadzidzidzi.

II. Kapangidwe Koyamba

Kapangidwe Kabwino:

Thupi la Valavu:Kawirikawiri zimapangidwa ndi chitsulo chosungunuka, mkuwa, kapena chitsulo chosapanga dzimbiri, zomwe zimapangitsa kuti makina azikhala olimba komanso kuti mafuta azigwira ntchito bwino.

Chigawo Chachikulu Cha Disc/Valve:Kawirikawiri mkuwa kapena chitsulo chosapanga dzimbiri, chopangidwa ngati mtundu wozungulira (monga gulugufe) kapena mtundu wa plunger kuti zitsimikizire kutseka bwino komanso kuyenda bwino.

Zigawo Zotsekera:Gwiritsani ntchito mphete zotsekera zosagwira mafuta, zotentha kwambiri, komanso zokalamba zopangidwa ndi zinthu monga Nitrile Butadiene Rubber (NBR) kapena Fluorocarbon Rubber (FKM) kuti zitsimikizire kuti kutsekerako kumagwira ntchito kwa nthawi yayitali.

Chingwe Chogwirira Ntchito/Gudumu Lamanja:Njira yogwiritsira ntchito yakunja, nthawi zambiri imakhala ndi zizindikiro za "Open/Tsekani". Ma model apamwamba amatha kukhala ndi chogwirira chotsekedwa kapena wrench yomangidwa kuti apewe kugwira ntchito mwangozi.

Kulumikizana kwa Flange:Malekezero onse awiri a valavu ali ndi ma flanges okhazikika (monga GB, ANSI, miyezo ya DIN) kuti azitha kulumikiza mosavuta ku thanki ya transformer ndi mapaipi akunja.

Kusankha/Kutulutsa Madzi:Chotulutsira ma valve nthawi zambiri chimakhala ndi ulusi wamkati kapena cholumikizira cholumikizira mwachangu chomangirira mapayipi otulutsira madzi kapena mabotolo apadera.

III. Ntchito Zazikulu ndi Magwiritsidwe Ntchito

Kusankha Mafuta Oteteza:Amagwiritsidwa ntchito pochotsa zitsanzo za mafuta panthawi yoyesera kapena kusanthula zolakwika. Izi zimathandiza mayeso ofunikira mongaKusanthula kwa Mpweya Wosungunuka (DGA), kuchuluka kwa chinyezi, magetsi owonongeka, ndi dielectric dissipation factor, zomwe ndi njira zofunika kwambiri zowunikira thanzi la mkati mwa transformer (monga kutentha kwambiri, kutulutsa, kuwonongeka kwa insulation).

Kukonza Transformer ndi Kusintha Mafuta:Amagwira ntchito ngati malo olowera/kutulutsira mafuta posefa, kudzazanso, kapena kusintha mafuta oteteza kutentha.

Kuyang'anira/Kukonzanso Transformer:Amagwiritsidwa ntchito kutulutsa mafuta kuchokera mu thanki kupita ku chosungiramo zinthu musanayang'ane mkati kapena ntchito yayikulu yamkati.

Kutulutsa Mafuta Pangozi:Ngati vuto lalikulu la mkati (monga moto, kuphulika kwa mafuta), zimathandiza kuti mafuta atulutsidwe mwachangu kupita ku dzenje losungiramo zinthu kuti apewe kufalikira kwa moto komanso kuipitsidwa kwa chilengedwe.

Madzi Ochokera Pansi ndi Kutulutsa Madzi:Zimalola kuchotsa madzi ochulukirapo ndi tinthu tating'onoting'ono kuchokera pansi pa thanki.

IV. Zinthu Zofunika Kwambiri ndi Ubwino

1.Kudalirika Kwambiri Kosindikiza:Kapangidwe kake ka zisindikizo ziwiri kamaonetsetsa kuti palibe kutuluka kwa madzi m'thupi lonse la transformer (mwina kwa zaka makumi ambiri), zomwe zimathandiza kuti mafuta asatayike pang'ono kuti asayamwe chinyezi ndi okosijeni.

2.Ntchito Yosavuta Komanso Yotetezeka:Kuzungulira kwa madigiri 90 kumatsegula kapena kutseka valavu, zomwe zimafuna mphamvu yochepa yogwirira ntchito. Zizindikiro zotsegula/kutseka bwino komanso chitetezo ku ntchito yangozi zimawonjezera chitetezo cha ogwira ntchito.

3.Kapangidwe Kosagwira Ntchito Kwambiri:Chitseko cha diski/valavu chikatsegulidwa bwino, chimalepheretsa mafuta kuyenda bwino, zomwe zimathandiza kuti madzi azituluka mwachangu komanso kuti zinthu ziziyenda bwino.

4.Kugwirizana Kwambiri ndi Zinthu:Zipangizo zonse zomwe zimakhudzidwa ndi mafuta oteteza kutentha (zitsulo, zisindikizo) zimagwirizana bwino, zomwe zimaletsa dzimbiri kapena kupanga zinthu zomwe zingayambitse kukalamba kwa mafuta.

5.Kapangidwe Kolimba Ndi Kolimba:Imapirira kugwedezeka, kufalikira/kupindika kwa kutentha, komanso kusinthasintha kwa mphamvu yamkati panthawi yogwira ntchito ya transformer.

6.Maulalo Okhazikika:Miyeso ya flange ikugwirizana ndi miyezo yapadziko lonse lapansi kapena yadziko lonse, kuonetsetsa kuti imasinthana bwino komanso yosavuta kuyiyika/kulumikiza ku zida zakunja.
