Momwe Mungatetezere Lupu mu Ntchito Yofanana ya Jenereta

Kugwira ntchito kofanana kumatanthauza kuti ma seti a jenereta awiri kapena kupitilira omwe ali ndi voteji yofananira ndi gawo lokhazikika amaphatikizidwa mu basi yomweyo kuti apereke mphamvu yogwira komanso mphamvu zotakataka pa chipangizocho.Jenereta imodzi imayambika poyamba, ndiyeno magetsi opangidwa amatumizidwa ku basi.Pambuyo pa seti ina ya jenereta yayamba, ikufanana ndi jenereta yapitayi yomwe yakhazikitsidwa panthawiyi.Panthawi yotseka, makina a jenereta sadzakhala ndi mphamvu yachilendo, ndipo crankshaft sidzakhudzidwa mwadzidzidzi.Komabe, dera lonse lapano liyenera kuganiziridwa mozama pamasitepe ogwirira ntchito limodzi.

1. Bwezerani ntchito.Mkhalidwe wamakono wa mphamvu yobwereranso umayamba chifukwa cha liwiro losiyana ndi voteji mayunitsi a jenereta , ndiko kuti, gawo limodzi la jenereta lili ndi mphamvu zabwino ndipo gawo lina lili ndi mphamvu zoipa.M'mawu ena, unit ndi mphamvu zoipa amakhala katundu pa nthawi ino (zochitika panopa otsika pafupipafupi ndi zosagwirizana liwiro la unit).Mphamvu yamagetsi ikakhala yosagwirizana, gawo lomwe lili ndi voteji lalitali limapereka voteji imodzi yokhazikika komanso yokhazikika kugawo lomwe lili ndi voteji yotsika (chizindikiro chabwino cha ammeter a unit iyi).Ndizofanana ndi kuwonjezera gulu la condenser mu dongosolo lamagetsi.Panthawi imeneyi, unit ndi otsika voteji amakhala katundu lalikulu ndipo amalandira lalikulu zotakataka panopa kuonetsetsa voteji bwino mayunitsi awiri (ammeter wa unit limasonyeza mosinthana).Panthawi yowunikira, mphamvu yamagetsi yamtundu umodzi ikawonjezeka kapena voteji ya gawo lina ikuwonjezeka, gawo limodzi limakhala ndi mphamvu zosinthira, ndipo machitidwe ake apano ndi pafupifupi 20% yamagetsi omwe adavotera.Sinthani machitidwe otumizirana mauthenga, maulendo ndi ma alarm, koma osatseka.

2. Zopitilira.Mphamvu yotulutsa ya jenereta yamasiku ano ndiyofanana, ndipo mulingo wake wodzaza ndi wotsika kwambiri.Ambiri aiwo ndi pafupifupi 5% ya mphamvu zotulutsa.Nthawi yololedwa yonyamula ndi 15 ~ 30 mphindi, mpaka mphindi 60.Pamapeto pake, nthawi ino Jenereta ya Perkins idzakhala yotentha, kutsekemera kwa chingwe kudzachepetsedwa, ndipo moyo wautumiki udzachepetsedwa.Chifukwa chake, ngati palibe chofunikira chapadera pakukhazikitsa chitetezo chowonjezereka, chitetezo cha overcurrent chikhoza kukhazikitsidwa pa 110% ya zomwe zidavotera pano.Pakuyezetsa katundu, bweretsani zomwe zilipo ku 110% yazomwe zidavotera pano, ndikuchitapo kanthu mopitilira muyeso.Ulendo, alamu komanso osatseka.

3. Kuchuluka kwamagetsi.Pamene jenereta akonzedwa ntchito kufanana, ndi mantha oscillation wa dongosolo magetsi.Pamene oscillation ikuchitika, kukwera kwamagetsi kwa dongosolo kumakhala kosavuta kutulutsa zowonongeka kwa magetsi ndi magetsi, zomwe zimapangitsa kuti magetsi ndi magetsi asagwire ntchito bwino.Chifukwa chake, ma seti a jenereta omwe amagwiritsidwa ntchito limodzi ali ndi chitetezo chochulukirapo, ndipo mtengo wake wokhazikitsidwa ndi 105% wa voteji ovotera ndi wabwinoko.Short circuit overvoltage relay, ulendo, shutdown ndi alarm.Zitha kuwoneka kuti kusintha kwa liwiro (kawirikawiri) kwa magawo awiriwa kuyenera kukhala kofanana musanayambe kukonzekera ntchito yofanana ya mayunitsi a jenereta.Mofananamo, liwiro la makina oyambirira kapena gulu lomwe liyenera kufananizidwa likhoza kusinthidwa molingana ndi liwiro la kusinthasintha kwa tebulo mu nthawi yomweyi, kotero kuti kayendetsedwe ka tebulo mu nthawi yofanana ikhoza kusinthidwa mozungulira kapena mosiyana. .Kuthamanga kwapang'onopang'ono kumakhala bwinoko, koma cholozera cha tebulo mu nthawi yomweyo chiyenera kuzunguliridwa chisanakhale mbali ndi mbali.Pomaliza, mutatha mbali ndi mbali, yang'anani ngati panopa ndi mphamvu ya mayunitsi awiriwa ali oyenerera.Ngati kusiyanako kuli kwakukulu kwambiri, sinthani koboti yothamanga kuti mphamvuyo ikhalebe.
