Imbangela Ukuhlaziywa Kwe-500KVA Yegenerator Diesel Abnormal Bush Burning Faults

Injini kadizili iyingxenye enkulu yegenerator kadizili engu-500KVA, kunezizathu eziningi ezidala ukushisa kwehlathi lenjini kadizili.Ukushoda kukawoyela wenjini enjinini kadizili kungesinye sezizathu ezinkulu zokushiswa kwenjini kadizili.Uma injini ye-diesel isebenza ngaphandle kwamafutha, kufanele ishise ihlathi, kodwa ihlathi lingase lishiswe lapho amafutha engekho.

Namuhla, amandla e-Dingbo, a umenzi wamajeneretha edizili , ihlaziye izimbangela zamaphutha okushiswa kwehlathi okungavamile kwejeneretha yedizili engu-500KVA.Ngethemba ukuthi lesi sihloko siwusizo kuwe.

1. Ukuhlaziya imbangela

Enqubweni evamile yokusebenza yenjini kadizili, kukhona imvume phakathi kwejenali ye-crankshaft kanye ne-bearing bush kanye nefilimu kawoyela ekhona ukwenza ukuthambisa okuwuketshezi.Ngale ndlela, ukulahlekelwa kwe-friction kuncane, ukushisa okukhiqizwa ukungqubuzana kuncane, ukushisa kuthathwa ngamafutha, futhi izinga lokushisa lokusebenza livamile.Uma isihlahla esithwalayo sithintana ngqo nephephabhuku ukuze senze isimo sokungqubuzana esomile ngokwengxenye, ukusetshenziswa kwamandla okungqubuzana kuzokhuphuka kakhulu, futhi kuzokhiqizwa inani elikhulu lokushisa kwe-friction, elizohlakazwa isihlahla esithwalayo, kuyilapho ukushisa. athathwe amafutha akuningi.Ukushisa kuzonqwabelana esihlahleni esithwalayo futhi izinga lokushisa lizokhuphuka ngokuqhubekayo.Lapho izinga lokushisa lidlula indawo yokuncibilika kwe-alloy endaweni yesihlahla esithwalayo, i-bearing bush surface izoqala ukuncibilika kuze kube yilapho kwenzeka ukulahlekelwa ukuvutha, okuholela ekuhlulekeni kwenjini ye-diesel.

2. Izici ezifanele ezidala ukwehluleka

A. Izinga lokushisa likawoyela liphezulu kakhulu noma liphansi kakhulu

Uma izinga lokushisa likawoyela liphansi kakhulu, i-viscosity yamafutha okugcoba iphezulu kakhulu futhi i-fluidity impofu.Ikakhulukazi esiteji sokuqala esibandayo, inani lamafutha angena ku-crankshaft lincane, okulula ukwenza isihlahla esithwalayo sithintane ngqo nejenali ye-crankshaft futhi sisheshise ukuguga nokulimala kokuthwala.Lapho izinga lokushisa likawoyela liphezulu kakhulu, i-viscosity yamafutha okugcoba iphansi kakhulu futhi amandla efilimu kawoyela ayancipha, okuholela ekunciphiseni kokuqina kwefilimu kawoyela, okubuye kube lula ukubangela ukuguga kanye nokulimala isihlahla esizalayo.Ngokuvamile kunenkolelo yokuthi izinga lokushisa eliphezulu lamafutha okugcoba enjini ye-diesel ngu-130 ℃.Kodwa-ke, ukuze kunwetshwe ngokugcwele impilo yesevisi ye-bearing, izinga lokushisa elivamile kufanele ligcinwe ku-95 ~ 105 ℃.

B. Ukuzinza kwe-oxidation yamafutha okugcoba

Ukumelana ne-thermal oxidation kawoyela wokugcoba kunomthelela omkhulu ekugcobiseni phakathi kwe-crankshaft ne-bearing.Uma amafutha okugcoba amabili ahlukene asetshenziswa ku-prototype efanayo futhi esebenza ngokuqhubekayo ngaphansi kwesimo esifanayo sokusebenza, imiphumela elinganisiwe izohluka.

C. Ukugunyazwa kokuhlanganisa okungafanele

Ukuze kuthuthukiswe isimo sokugcotshwa kwenjini eyinhloko yenjini kadizili ekhona futhi kuvinjwe ukushiswa, imvume phakathi kwebheringi kanye nejenali ye-crankshaft kufanele ilawulwe ngokuhambisana ngokuqinile nezidingo zebhukwana lokusebenza kwenjini kadizili.Lapho ushintsha isihlahla esithwalayo, hlola ukuzungeza kanye ne-cylindricity yejenali ye-crankshaft.Uma yeqa umkhawulo, izopholishwa ukuze igweme ukunciphisa indawo yokuxhumana yejenali kanye nesihlahla esithwalayo kanye nokwandisa ingcindezi yendawo ngayinye yeyunithi.Ngaphezu kwalokho, ukucaciswa kwe-axial ye-crankshaft kuzolawulwa.Uma ukuguga kweqa umkhawulo, kuzolungiswa ngesikhathi.

D. Ukuwohloka kwamafutha okugcoba

Ngokuvamile, ngesikhathi kusetshenziswa uwoyela wokugcoba, ngenxa yokugqokwa kwesilinda se-cylinder injini ye-diesel kanye neringi ye-piston, kanye nokushintshwa kwemvume yokuvula indandatho ye-piston kanye nendawo yokuvula, izinga lokushisa eliphezulu kanye nengxubevange ephezulu evuthayo egelezela ngaphakathi. i-crankcase iyanda, engagcini nje ukwandisa izinga lokushisa lamafutha okugcoba, kodwa futhi isheshisa i-oxidation kanye ne-polymerization yamafutha okugcoba.Ngesikhathi esifanayo, ngenxa yokuxuba imikhiqizo evuthayo yenjini ye-diesel, ukuxuba uthuli lwangaphandle kanye nemfucumfucu yensimbi, kanye nokusetshenziswa kwezithasiselo kumafutha okugcoba, ukuwohloka nokuwohloka kwesivinini samafutha okugcoba kuyashesha kakhulu.Lokhu akugcini nje ngokukhuphula ukuguga kanye nokugqwala kwepheya elishayisanayo lengxenye yokugcoba yenjini ye-diesel, kodwa futhi kuyisizathu esiyinhloko sokulahlekelwa okuvuthayo kwe-bearing.

E. Izinga eliphansi lamafutha okugcoba

Injini kadizili isebenzisa uwoyela wokugcoba osezingeni eliphansi noma uwoyela mbumbulu wekhwalithi ephezulu lapho isetshenziswa.Uma izinga lekhwalithi likawoyela wokugcoba lingahlangabezani nezidingo zomkhiqizi wenjini kadizili, kuzoholela nasekuhlulekeni kokushiswa kukaBush kwenjini kadizili.

F. Inkinga yekhwalithi yokuzala isihlahla

Uma kusetshenziswa izinto eziphansi, ukumelana nokushisa okuphezulu kanye nomthamo wokuzala wesihlahla esithwalayo akwanele.Ngisho noma umfutho kawoyela ujwayelekile futhi nenani likawoyela lanele, iphutha lokushiswa kweBush lizobangelwa.

G. Ukudlidliza kwenjini kadizili kukhulu kakhulu ngesikhathi sokusebenza

Ukudlidliza kwenjini yedizili ngesikhathi sokusebenza kukhulu kakhulu ngenxa yokulimala kokumuncwa noma ezinye izizathu;Kungenzeka futhi ukuthi i-element encibilikayo ye-crankshaft yenjini ye-diesel yonakalisiwe, okwenza injini ye-diesel crankshaft idlidlize kakhulu;Ngemva kokusebenza isikhathi eside, isihlahla esithwalayo singaxega, okubangele ukushiswa kweBush noma ukwehluleka ukushelela.

H. Izinga lokushisa lenjini kadizili liphezulu kakhulu

Ngenxa yokwehluleka kwesistimu yokupholisa noma ezinye izizathu, izinga lokushisa eliphelele kanye nezinga lokushisa likawoyela lenjini ye-diesel liphezulu kakhulu, okuholela ekuhlulekeni kokushiswa kweBush kwenjini yedizili ngemva kokusebenza isikhathi eside.

3. Izinyathelo zokuphepha zokusetshenziswa 500kva generator diesel

a.Ukugcinwa okuvamile: hlanza izingxenye, dredge i-oil passage, engeza noma ushintshe uwoyela ngesikhathi ukuze uvimbele uwoyela ukuthi ungagugi noma ungcole kakhulu futhi uvimbele umzila kawoyela.

b.Khetha uwoyela wokugcoba ohlangabezana nezidingo zomkhiqizi wenjini ye-diesel futhi uyigcine ngokucophelela njengoba kudingeka.

c.Ngaphambi kokuqala injini ye-diesel, hlola ngokucophelela inani lamafutha okugcoba.Uma inganele, yengeze ngokwemithethonqubo.

d.Ngesikhathi sokuqalisa okubandayo, qala usebenze ngesivinini esingenzi lutho ngaphansi kokungalayishi imizuzu emi-3 ukuya kwemi-5, bese kancane kancane ushintshela ekusebenzeni okushesha kakhulu noma komthwalo osindayo.

e.Akuvunyelwe ukusebenzisa i-generator diesel isikhathi eside ngaphansi kokugcwala ngokweqile ukuze kugwenywe ukusheshisa okusheshayo;Uma kutholakala ukuthi ilambu le-alamu yomfutho kawoyela livuliwe, thola imbangela bese uyiphatha kahle ngaphambi kokuqhubeka nokusebenza.

f.Ngesikhathi sokulungiswa, qaphela ukuhlola zonke izingxenye zesistimu yokugcoba.Izingxenye ezibalulekile azikwazi ukushintshwa (isb. ucingo lwensimbi alukwazi ukuthatha indawo yephinikhodi ye-cotter, njll.).Lapho uhlanganisa, sebenzisa amafutha okugcoba ahlanzekile.

g.Lapho ushintsha isihlahla esisha esithelayo, hlola ubude besihlahla esithelayo.Isihlahla esithwalayo sifushane kakhulu ukuze siqinisekise ukulingana kwayo okuthembekile nejenali kanye nokukhishwa okuhle kokushisa;Lapho isihlahla esithwalayo siside kakhulu, isixhumi esibonakalayo sizoba nokukhubazeka, okuzoholela ekugwemeni kwe-shaft.

h.Hlola njalo umthelela wokupholisa wesistimu yokupholisa yenjini kadizili, qaphela ukwengeza into epholile futhi uqinise noma ubuyisele ibhande lefeni ngesikhathi ukuze uqinisekise ukuthi uhlelo lokupholisa luhlala lusesimweni esihle.
