Abin da ke Haɓaka Ƙararrawar Diesel Genset Failure

Saitin janareta na Diesel kayan aiki ne na samar da wuta, yana amfani da man dizal, wanda injin dizal ke tukawa don samar da wutar lantarki.Gabaɗaya saitin janareta na dizal ya ƙunshi injin dizal, janareta, majalisar kulawa, tankin mai, baturin ajiya don farawa da sarrafawa, na'urar kariya, majalisar gaggawa da sauran abubuwa.

Ayyukan ƙararrawa na saitin janareta na diesel zai fara da sauti ta atomatik lokacin da janareta na diesel yana da halaye masu zuwa:

1. Yawan gudu.

2. Babban zafin ruwa a cikin tankin ruwa.

3. Karancin mai.

4. Sama da nuni na yanzu akan kwamiti mai kulawa.

5. Sama da wutar lantarki.

6. Lokacin da wasu al'amura marasa kyau suka faru, aikin ƙararrawa na saitin janareta na diesel yana farawa ko aikin kare kai na janareta dizal yana taka rawa.

Menene dalilin kurakuran rufewar ƙarancin wutar lantarki?

1.Mechanical gudun tsari na diesel engine

Tsarin saurin injin dizal ya haɗa da tsarin saurin lantarki da tsarin saurin injin.Idan ka'idar saurin sauri ce, akwai injin famfo mai akan injin dizal don sarrafa ƙarar mai da da'irar mai, da alama ana kiransa fam ɗin man dogo na gama gari.Akwai sandar ja a kai don sarrafa adadin mai.Ana kiransa saurin sarrafa sandar ja na ɗan lokaci.Ana rarraba sandar tsayi mai iyaka (high-gudun) saman sanda mai sarrafa saurin gudu a ɓangarorin biyu na saurin sarrafa sandar ja, kuma za a ba da rahoton ƙananan matsa lamba bayan farawa da gudu na 20s.Idan wutar lantarki da mita har yanzu ba a cikin ƙimar al'ada ba, dalili na iya zama sauri.Za mu iya kokarin daidaita tsari saman sanda.Idan genset diesel yana da kurakurai, dole ne a sami babban laifi.Bayan warware babban kuskure, duk matsalolin za a warware.

2.Voltage samfurin layin sako-sako da

Idan layin ya kwance, ba za a sami wutar lantarki ba.

3.Sauran maganadisu

Idan janareta ba shi da ragowar maganadisu, ba za a iya gina tsarin wutar lantarki na janareta a farkon ba.Domin wannan matsala, muna bukatar mu san nawa irin ƙarfin lantarki da excitation fitarwa na AVR regulator farantin na janareta ne, sa'an nan kuma haɗa daidai ƙarfin lantarki tushen a kan excitation fitarwa line don magnetization (nau'in lantarki kamata ya zama m, da kuma polarity kamata. ba za a juya ba).

3. Laifin kasa

Idan layin da ke fita ya kasance ƙasa mai matakai uku, ƙarfin lantarki da na yanzu suna da ƙasa sosai.A wannan lokacin, galibi ana bincika ko na'urar fitarwa ta ƙasa (kamar wuƙar ƙasa) tana rufe ko ƙasa.

4.Kayyade laifin farantin

Saboda canjin yanayi na muhalli, ma'aunin matsi na AVR mai daidaita faranti ba su da amfani kuma suna buƙatar gyarawa.Gabaɗaya magana, irin wannan matsala ba za ta bayyana a cikin kwayoyin halittar diesel ba.Saboda ma'auni na farantin mai daidaita matsa lamba ƙayyadaddun ƙima ne (400V), ba za mu iya daidaita su gabaɗaya ba.Naúrar da aka yi amfani da ita don aiki ɗaya kawai za ta iya samun wannan matsalar.Domin ana sarrafa mai sarrafa wutar lantarki ta AVR bisa ga ƙarfin lantarki na babban bas yayin aiki a layi daya, ba zai iya canzawa ba.A wannan lokacin, akwai siginar sarrafa wutar lantarki da aka aika zuwa ga mai sarrafa wutar lantarki ta AVR ta hanyar na'urar aiki ta layi daya.A wannan yanayin, ko dai bincika ko an haɗa siginar sarrafa wutar lantarki ba daidai ba ko ƙoƙarin amfani da sarrafa lantarki (na'urar aiki ɗaya, mai sarrafa wutar lantarki, da sauransu) don daidaita wutar lantarki cikin sauri lokacin farawa.

5.The varistor ko rectifier gada diode a kan janareta winding ya lalace

Ayyukan varistor shine kunna varistor idan akwai kuskuren over-voltage don rage ƙarfin lantarki.Idan varistor ya lalace ko kunna shi saboda wasu dalilai, ana iya tunanin cewa wutar lantarki dole ne ya yi ƙasa sosai.Gadar gyara tana da diode 6.Ana amfani da saitin wutar lantarki na DC don samar da mai sarrafawa da na'urorin motsa jiki.Idan diodes masu gyara gada sun lalace, aikin mai sarrafa da na'urorin motsa jiki za su yi rauni sosai.

Da fatan bayanin da ke sama zai taimaka muku.Har ila yau, muna samar da dukkanin injinan dizal, muna da masana'anta a Nanning China tun daga 2006. Idan kuna neman masu samar da diesel, da fatan za a tuntube mu ta imel Dingbo@dieselgeneratortech.com, za mu yi aiki tare da ku.
