Kungani I-Bearing of 750kva Generator Ilimele

A. Izimbangela zokulimala kuka-750kva generator diesel.

1. Isizathu esiyinhloko sokuzala ukulimala ukulimala kokukhathala.

Ngenxa yokuthi ubukhulu kanye nesiqondiso somthwalo ekushintsheni kokuthwala ngesikhathi, lapho umthwalo ungazinzile, ifilimu yamafutha eyunifomu futhi eqhubekayo ayikwazi ukugcinwa phakathi kwezindawo zokungqubuzana ezithwalayo, futhi ukucindezelwa kwefilimu yamafutha nakho kushintsha i-Pulsatively.Lapho ubukhulu befilimu yamafutha buncane, izinga lokushisa eliphezulu lenzeka endaweni yendawo ye-bearing surface, okunciphisa kakhulu amandla okukhathala kwe-alloy layer.Ukwengeza, ukukhiqizwa okumpofu kanye nokuhlanganiswa kwe-bearing ngokwayo kuyimbangela eqondile yokucwecwa kwe-alloy layer.

2. Ngaphezu kokugqoka nokucwecwa.

Ukugqwala kwe-sliding bearing kufanele futhi kunakwe, okuncike kakhulu kwikhwalithi, izinga lokushisa, ingcindezi kanye nomthwalo othwala amafutha.Ingxenye ephezulu yomthwalo wokuthwala ijwayele ukugqwala, futhi i-asidi ephilayo kanye ne-sulfide ekhiqizwa ukuwohloka kwamafutha okugcoba ekushiseni okuphezulu yizimbangela zokuthwala ukugqwala.

3. Ukushiswa ukuzala.

Okusho ukuthi, isizathu esiyinhloko sokushiswa kwamathayili okuvamile ukuthi imvume incane kakhulu, ukugcoba kumpofu futhi kunezinkinga ekusetshenzisweni nasekusebenzeni.

B. Indlela yesondlo ye amajeneretha edizili ukuzala.

1. Ngesikhathi sokugcinwa kwejeneretha ye-diesel yepompo yamanzi, qaphela indandatho kawoyela ukuze ugcobe i-sliding bear.Inani lamafutha okuzala kufanele libalwe.Ngokuvamile, ayijovwe ngesikhathi sokusebenza.

Uma umthamo kawoyela ungaphansi kwezinga elishiwo elishiwo, i-alama akufanele iphonse uwoyela ukuze igweme ukuchaphazeka ekujikeni.Amafutha enjini kufanele akhishwe ukuze ahlolwe isampula njalo.Uma umbala kawoyela uba mnyama, ubhuqu, futhi kukhona amanzi noma ukungcola, uzoshintshwa.Lapho ukuthwala kushisa, esikhundleni salo faka amafutha amasha.

2. Ngokuvamile, amafutha kufanele ashintshwe njalo ngamahora okusebenza angu-250-400, kodwa okungenani njalo ngesigamu sonyaka.

Lapho ushintsha uwoyela, hlanza i-bheringi ngophalafini bese uyixubha ngophethiloli ngaphambi kokujova uwoyela wokugcoba omusha.Kumamotho anebhola noma ama-roller bearings, amafutha adinga ukushintshwa lapho esebenza cishe amahora angama-2000.Uma i-bearing isetshenziswa endaweni enothuli neswakeme, amafutha okugcoba kufanele ashintshwe njalo ngokuya ngesimo.

3. Ngaphambi kokuqala ijeneretha esinesikhathi eside ingasebenzi:

Uma i-bearing ifakwe uphethiloli noma iwohlokile, kufanele ihlanzwe kuqala.Uma ukuthwala kungcolile, kufanele kuhlanzwe kuqala.Gcwalisa amafutha ahlanzekile.Inani lokugcwalisa liyi-2/3 yesikhala sekamelo lokuthwala, futhi akuvunyelwe ukugcwalisa kakhulu.

Lokhu okungenhla kuyisizathu sokulimala kwe-generator ye-diesel ehambisana namandla e-Dingbo kanye nokugcinwa kwe-bearing.Ngethemba ukuthi isingeniso esingenhla singasiza abasebenzisi.Ziningi izizathu zokulimala kokuthwala ijeneretha yedizili.Abasebenzisi kufanele banake isondlo lapho besebenzisa i-genset ye-diesel.

Ukusetshenziswa kwansuku zonke nokugcinwa kwesethi yejeneretha yedizili engu-750kva

A. Amalungiselelo ngaphambi kokuqala i isethi yejeneretha .

1. Hlola ukuthi izixhumi nezixhumi zikhululekile yini nokuthi izingxenye ezihambayo ziyaguquguquka yini.

2. Hlola izinqolobane zikaphethiloli, uwoyela wenjini namanzi okupholisa ukuze uhlangabezane nezidingo eziyisisekelo.

3. Hlola ukuthi iswishi yomoya olayishayo kukhabhinethi yokulawula kufanele ibe sesimweni sokucisha (noma ivaliwe), bese usetha i-voltage knob endaweni yamandla kagesi aphansi.

4. Ukulungiswa ngaphambi kokuqala injini ye-diesel kuzokwenziwa ngokuhambisana ngokuqinile nezidingo zebhukwana lokusebenza (izinhlobo ezahlukene zamamodeli zingahluka kancane).

5. Uma kunesidingo, yazisa umnyango wokuphakelwa kukagesi ukuthi udilize i-circuit breaker noma usethe switch switch yekhabhinethi yokushintsha phakathi kwamandla amakhulu kanye nejeneretha kadizili iye endaweni ephakathi (neutral state) ukuze unqamule ulayini wokuphakelwa kwamandla kagesi aphezulu amandla amakhulu.

B. Izinyathelo zokuqalisa:

1. Isethi yejeneretha engalayishi izoqalwa ngokwendlela eshiwo kubhukwana lokusebenza kwenjini kadizili.

2. Lungisa isivinini kanye ne-voltage ngokwezidingo zebhukwana lokusebenza kwenjini ye-diesel (iyunithi yokulawula i-electromechanical ezenzakalelayo ayidingi ukulungiswa).

3. Ngemuva kokuthi kujwayelekile, setha ukushintshwa komthwalo ekugcineni kwe-generator, bese uvala kancane kancane umshini wokushintsha umthwalo ngesinyathelo ngokuya ngenqubo yokusebenza yokushintsha ukuze ungene esimweni sokusebenza kwamandla okusebenza.

4. Ngesikhathi sokusebenza, hlala unake ukuthi i-current phase-three ilinganisela nokuthi isibonakaliso sensimbi ngayinye kagesi ijwayelekile.

C. Izinyathelo zokuqapha ngesikhathi sokusebenza kwesethi yejeneretha yedizili:

1. Hlola njalo izinguquko zezinga lamanzi, izinga lokushisa likawoyela nomfutho kawoyela, futhi wenze amarekhodi.

2. Uma kwenzeka ukuvuza kwamafutha, ukuvuza kwamanzi kanye nokuvuza komoya, kuzolungiswa ngesikhathi.Uma kunesidingo, yeka ukusebenza bese ubika kumhlinzeki wesevisi ukuze uthole ukwelashwa endaweni.

3. Yenza irekhodi lokusebenza.

D. Ukuvala isethi yejeneretha:

1. Khipha umthwalo kancane kancane futhi unqamule iswishi yomoya ezenzakalelayo.

2. Uma kuyiyunithi yokuqalisa umoya, hlola umfutho womoya webhodlela lomoya.Uma umfutho womoya uphansi, uwugcwalise ube ngu-2.5MPa.

3. Vala ngokuhambisana nezidingo zebhukwana lokusebenza elifakwe injini yedizili noma isethi yejeneretha yedizili.

4. Hlanza bese ulinda iphampu yamanzi ngokuzayo.
