Imiyalo Yokulungisa Ye-Volvo Diesel Generator Ebusika

Qala, yima futhi uqhube injini

1. Shisisa

Idivayisi yokushisa ihlukaniswe ngokuyinhloko ekushiseni komoya wokungenisa kanye nokushisa kwamanzi kwe-cylinder liner.Iningi lezinhlobo zezinjini zeVolvo i-diesel genset , njengezinjini ezingu-8L, 11L kanye ne-13L, zifakwe idivayisi yokushisa yangaphambili njengejwayelekile, futhi idivayisi yokushisisa amanzi ye-cylinder liner idinga ukungezwa ezindaweni ezimbalwa kakhulu.Ngokwemvelo yemakethe yemishini yaseHong Kong, ukucushwa kwedivayisi yokushisa umoya yokungenisa kungaqinisekisa ukuqala kahle kwenjini.Ezindaweni ezikhethekile, njengendawo ephakeme yokuphakama kwe-Qinghai Tibet Plateau, ngenxa yokuncipha kokuqukethwe komoyampilo, kuyanconywa ukuthi kwengezwe idivayisi yokushisisa uphethiloli ukuze kuqalwe ukusiza.Akuvunyelwe ukusebenzisa umjovo we-ether ukusiza ukuqalisa, okuzoqhuma endaweni yokungena komoya ezimeni ezinzima.

2. Ngaphambi kokuqala

Ngaphambi kokuqala injini, naka lezi zinto ezilandelayo:

Hlola futhi uqinisekise ukuthi izinga likawoyela liphakathi kwezikali ezincane neziphezulu.

Hlola futhi uqinisekise ukuthi awekho amafutha, uphethiloli kanye nokuvuza okupholisayo.

Hlola futhi uqinisekise ukuthi izinga lokupholisa kanye nerediyetha akuvinjiwe ngaphandle.

3. Isivinini sokungenzi lutho

Emshinini we-VE, okwamanje, isivinini sokungenzi lutho esisethwe abakhiqizi abaningi abakhulu benjini siphakathi kuka-650-750 rpm.Ngemva kokuqala injini, ungakwazi ukunyathela ngokufanelekile isisheshisi ukuze ukhuphule isivinini senjini, ukuze ukhuphule izinga lokushisa elipholile ngokushesha.Kubasebenzisi bomshini wase-Hong Kong, kunconywa ukuthi u-opharetha afudumeze injini imizuzu engu-2-3 ngemva kokungenzi lutho, kunokuba angene ngokuqondile kumodi yokusebenza.

4. Ukugijima

Hlola zonke izinsimbi ngqo ngemva kokuqala, bese uhlola amathuluzi ahlukahlukene njalo ngesikhathi sokusebenza.Naka ama-alamu akhiqizwa ngesikhathi sokusebenza, ikakhulukazi ama-alamu amakhulu afana nezinga eliphansi likawoyela, umfutho ophansi kawoyela kanye nezinga lokushisa eliphezulu lamanzi.Uma kwenzeka ama-alamu anjalo, kunconywa ukuthi ume ngokushesha futhi uthole futhi ubhekane namaphutha ngaphambi kokusetshenziswa.

5. Kulayishiwe

Enjinini ye-GE, kunconywa ukuthi wengeze umthwalo ophansi enjinini lapho izinga lokushisa le-coolant likhuphuka lifika ku-50 ℃, okuzosiza kakhulu ekwenyukeni kwezinga lokushisa elipholile lenjini.Ngemuva kokuthi izinga lokushisa elipholile likhuphukele ku-85-90 ℃, engeza umthwalo enanini elidingekayo, ukuze unciphise ukuguga kwenjini.

6. Vala

Ikakhulukazi, isethi ye-generator idinga ukuqashelwa ukuthi ngaphambi kokuvala, kuyadingeka ukuqinisekisa ukuthi i-breaker circuit inqanyuliwe ngendlela efanele, bese ingasebenzi imizuzu embalwa ngaphambi kokuvala.Kubasebenzisi bomshini we-VE, opharetha kufanele anake ukuvumela injini ibuyele esivinini sokungenzi lutho futhi iphole imizuzu engu-1-2 ngaphambi kokuma.Akunconywa ukuthi ume ngokushesha ngemva kokwehla ngesivinini esikhulu ukuvimbela ukushisa okuphezulu kwamafutha okuthwala i-turbocharger.Ngemuva kokuthi injini enesistimu yokwelashwa ngemuva kwe-SCR esigabeni sesine sokuphuma iyeka ukusebenza, idinga ukulinda imizuzu emi-2 ngaphambi kokuvala iswishi eyinhloko.Kule nqubo, uketshezi olusepayipini le-urea lumuncwa emuva ethangini le-urea.Uma amandla enqanyuliwe kusenesikhathi kakhulu, kulula ukubangela i-urea crystallization epayipini.

7. Ibhethri

Okokuqala, qinisekisa ukusebenza kahle kwebhethri, ngoba izinga lokushisa eliphansi kulula ukunciphisa umthamo webhethri, okuholela ekuhlulekeni kokuqala.Naka ukuthi izintambo zebhethri zithembekile yini futhi ziqinile, futhi uvikele indawo enomswakama ngasolwandle ukuze ugweme ukugqwala kwenqwaba yezintambo.

8. Ijubane eliphansi lesikhathi eside nokusebenza komthwalo ophansi

Injini isebenza ngesivinini esiphansi kanye nomthwalo ophansi isikhathi eside.Ngenxa yokushisa okuphansi ku-cylinder nokuvutha okungaphelele, ingxenye yephethiloli engashisiwe izokhishwa ngegesi yokukhipha.Ikakhulukazi ebusika, lapho izinga lokushisa liphansi, kulula ukudonsa uwoyela epayipini lokukhipha umoya.Ukuze kuqedwe lesi simo, kuyadingeka ukuqhuba injini ngomthwalo omkhulu isikhathi esithile.

Ukugcinwa kwe Isethi ekhiqiza udizili yakwaVolvo

1. Amafutha enjini

I-Volvo incoma kakhulu amafutha e-VDS-2 kanye ne-VDS-3, ahambisana nezinjini ze-Euro II ne-Euro III ngokulandelana.Lawa mafutha amabili angamafutha afaneleka kakhulu ezinjinini zakwaVolvo ahlolwe yimakethe.Ukuze ukhethe amafutha ane-viscosity ehambisanayo kanye nomkhiqizo ocaciswe kubhukwana lomsebenzisi, kunconywa ukuthi umsebenzisi awathenge kumenzeli ogunyaziwe ojwayelekile.Ukukhetha uwoyela wenjini yezinga eliphansi kungase kubeke engcupheni yokuhluleka kwamafutha enjini okuhambisanayo.Ezinjinini ezinamaleveli e-emission angaphezu kwezigaba ezine, sebenzisa amafutha angaphezu kwe-VDS-4.5 ngokuya ngebhukwana lomsebenzisi.Ezindaweni ezinamazinga okushisa aphansi ikakhulukazi kwezinye izindawo, abasebenzisi bangadinga ukukhetha amafutha asebusika ane-viscosity ephansi.

2. Amafutha amafutha

Ngenxa yomehluko omkhulu wezinga lokushisa ezindaweni ezihlukahlukene, injini idinga ukufaka uphethiloli esikhundleni sebanga elihambisanayo lapho ingena ebusika.Ngenxa yokushisa okuphezulu eningizimu, ukusetshenziswa kwe -10 # amafutha kaphethiloli ebusika kungahlangabezana nokusetshenziswa, kuyilapho enyakatho, izinga lokushisa elincane lingancishiswa libe - 30 ℃ noma ngisho nangaphansi ngenxa yamakhaza amakhulu.Kunconywa ukuthi abasebenzisi bashintshe -35# uwoyela wedizili, futhi bakhethe uphethiloli ngebanga elifanele elihambisana nezinga lokushisa kwezinye izifunda.

3. Ukupholisa

Ukusebenzisa ngendlela efanelekile isipholiso esikhethekile seVolvo kunganciphisa ukugqwala komzila wamanzi wenjini futhi kuvimbele ukugqwala kwesiteshi samanzi, ukuvaleka kwerediyetha ngenxa yokungcola kanye nokugqwala kwe-cylinder liner.Njengamanje, isixazululo sesitoko esingu-50% kanye nesisombululo esixubile samanzi esingu-50% sisetshenziswa eningizimu.Ezindaweni ezibandayo ikakhulukazi enyakatho, kunconywa ukuthi abasebenzisi basebenzise ingxube yesisombululo sesitoko esingu-60% kanye no-40% wamanzi ahlanzekile.Le ngxenye yokupholisa inganciphisa indawo yokuqandisa ibe - 54 ℃, engahlangabezana nezidingo zazo zonke izifunda ezisenyakatho.

4. Ukuhlunga komoya

Ezindaweni ezinesihlabathi esisindayo nendawo ezungezile enokhahlo, ukwakheka nokushintshwa kwesihlungi somoya kubaluleke kakhulu ukuvimbela ukuguga ngaphambi kwesikhathi kwenjini nokwelula impilo yesevisi yenjini.Kunconywa ukuthi abasebenzisi bathenge isihlungi somoya esindayo esinconywe umenzi, futhi isihlungi somoya kufanele sihlelwe endaweni lapho kungelula ukudla umlotha, futhi isihlungi somoya kufanele sishintshwe ngokuya nge-alamu esheshayo yesikhombi sokuhlunga umoya. .

Injini yokugcina isikhathi eside

Kwezinye izinjini ezidinga ukuvalwa isikhathi eside, ezinye izinkinga zidinga ukunakwa:

*Sebenzisa into epholile ehlangabezana nezidingo zokusebenza, ngaphandle kwalokho kungase kube nengozi yokuqhekeka kwesithwathwa.

*Nqamula isixhumi sebhethri bese ushaja ibhethri njalo.

*Kuzothathwa izinyathelo zokunqanda ukugqwala kumalunga nezingxenye zezingxenye zikagesi.

*Ipayipi lokukhipha umoya kumele livalwe ukugwema umonakalo omkhulu enjinini odalwe amanzi emvula noma izinto zangaphandle.

*Kulezo ezigcinwe isikhathi esingaphezu kwezinyanga eziyi-8, uwoyela wenjini nesihlungi kuzoshintshwa, futhi umsebenzi wokulwa nokugqwala uzokwenziwa njalo.

*Sicela ubhekisele kuManuwali yomsebenzisi ngezinyathelo zokuthi uqalise kabusha injini.
