Malangizo Othandizira a Volvo Diesel Generator mu Zima

Yambani, imani ndi kuyendetsa injini

1. Preheat

Chipangizo cha preheating chimagawidwa kukhala preheating air preheating ndi silinda liner madzi preheating.Mitundu yambiri ya injini za Volvo mafuta a dizilo , monga injini za 8L, 11L ndi 13L, zili ndi chipangizo chotenthetsera choyambira monga chokhazikika, ndipo chipangizo chotenthetsera madzi cha cylinder liner chiyenera kuwonjezeredwa m'madera ochepa kwambiri.Pamalo amsika amsika a Hong Kong makina, kasinthidwe ka chipangizo chotenthetsera mpweya chimatha kuonetsetsa kuti injiniyo yayamba bwino.M'malo apadera, monga malo okwera a Qinghai Tibet Plateau, chifukwa cha kuchepa kwa okosijeni, tikulimbikitsidwa kuwonjezera chipangizo chotenthetsera mafuta kuti chiyambirenso.Ndikoletsedwa kugwiritsa ntchito jakisoni wa ether kuti athandizire kuyambitsa, komwe kumaphulika munjira yolowera mpweya muzovuta kwambiri.

2. Musanayambe

Musanayambe injini, ganizirani zinthu zotsatirazi:

Yang'anani ndikuwonetsetsa kuti mulingo wamafuta uli pakati pa masikelo ochepera komanso apamwamba.

Yang'anani ndikutsimikizira kuti palibe mafuta, mafuta ndi zoziziritsa kutayikira.

Yang'anani ndikutsimikizira kuti mulingo wozizirira ndi radiator sizinatsekeredwe kunja.

3. Liwiro lopanda ntchito

Kwa makina a VE, pakali pano, liwiro lopanda ntchito lokhazikitsidwa ndi ambiri opanga injini ali pakati pa 650-750 rpm.Mukayamba injini, mutha kuponda moyenerera pa accelerator kuti muwonjezere liwiro la injini, kuti muwonjezere kutentha kozizira mwachangu.Kwa ogwiritsa ntchito makina a Hong Kong, tikulimbikitsidwa kuti wogwiritsa ntchitoyo azitenthetsa injini kwa mphindi 2-3 atatha kuchita, m'malo molowa mwachindunji.

4. Kuthamanga

Yang'anani zida zonse mwachindunji mukangoyambitsa, ndiyeno fufuzani zida zosiyanasiyana nthawi zonse mukamagwira ntchito.Samalani ma alarm omwe amapangidwa panthawi yogwira ntchito, makamaka ma alarm akuluakulu monga mafuta ochepa, mafuta ochepa komanso kutentha kwa madzi.Pakakhala ma alarm oterowo, tikulimbikitsidwa kusiya nthawi yomweyo ndikupeza ndikuthana ndi zolakwikazo musanagwiritse ntchito.

5. Yodzaza

Pa injini ya GE, tikulimbikitsidwa kuwonjezera katundu wocheperako ku injini kutentha kozizirira kukwera kufika pa 50 ℃, zomwe zingathandize kwambiri pakuwonjezeka kwa kutentha kwa injini.Kutentha kozizira kukakwera kufika pa 85-90 ℃, onjezerani katundu pamtengo wofunikira, kuti muchepetse kuwonongeka kwa injini.

6. Tsekani

Makamaka, makonzedwe a jenereta akuyenera kudziwidwa kuti musanayambe kutseka, ndikofunikira kuwonetsetsa kuti chowotcha chatsekedwa bwino, ndiyeno osagwira ntchito kwa mphindi zingapo musanatseke.Kwa ogwiritsa ntchito makina a VE, wogwiritsa ntchitoyo ayenera kulabadira kuti injiniyo ibwerere pa liwiro lopanda pake ndikuziziritsa kwa mphindi 1-2 isanayime.Sitikulimbikitsidwa kuti muyime mwamsanga mutangotsika kuchokera ku liwiro lalikulu kuti muteteze kutentha kwapamwamba kwa mafuta a turbocharger.Injini yokhala ndi SCR post-treatment system mu gawo lachinayi la emission imasiya kugwira ntchito, iyenera kudikirira mphindi 2 isanazimitse chosinthira chachikulu.Pochita izi, madzi omwe ali mupaipi ya urea amayamwanso mu thanki ya urea.Ngati mphamvu idadulidwa molawirira kwambiri, ndikosavuta kuyambitsa urea crystallization mupaipi.

7. Batiri

Choyamba, onetsetsani kuti batire ikugwira ntchito bwino, chifukwa kutentha kochepa kumakhala kosavuta kuchepetsa mphamvu ya batri, zomwe zimabweretsa kulephera koyambitsa.Samalani ngati mawaya a batri ndi odalirika komanso olimba, ndipo tetezani malo achinyezi m'mphepete mwa nyanja kuti musawononge mulu wa mawaya.

8. Kuthamanga kwa nthawi yayitali ndi ntchito yochepa yolemetsa

Injini imayenda pa liwiro lotsika komanso katundu wochepa kwa nthawi yayitali.Chifukwa cha kutentha kochepa mu silinda ndi kuyaka kosakwanira, gawo la mafuta osapsa lidzatulutsidwa ndi mpweya wotuluka.Makamaka m'nyengo yozizira, pamene kutentha kuli kochepa, kumakhala kosavuta kudontha mafuta kuchokera ku chitoliro chotulutsa mpweya.Kuti athetse chodabwitsa ichi, m'pofunika kuyendetsa injini ndi katundu waukulu kwa nthawi.

Kusamalira Zida zopangira dizilo za Volvo

1. Mafuta a injini

Volvo imalimbikitsa kwambiri mafuta a VDS-2 ndi VDS-3, omwe amafanana ndi injini za Euro II ndi Euro III motsatana.Mafuta awiriwa ndi mafuta oyenera kwambiri pama injini a Volvo omwe ayesedwa ndi msika.Kusankha mafuta omwe ali ndi viscosity yofananira ndi mtundu womwe wafotokozedwa mu bukhu la ogwiritsa ntchito, tikulimbikitsidwa kuti wogwiritsa ntchito awagule kuchokera kwa wothandizira wovomerezeka nthawi zonse.Kusankha mafuta a injini otsika kwambiri kumatha kutenga chiopsezo chofanana ndi kulephera kwamafuta a injini.Pama injini okhala ndi milingo yotulutsa pamwamba pa magawo anayi, gwiritsani ntchito mafuta pamwamba pa VDS-4.5 malinga ndi buku la ogwiritsa ntchito.Kwa madera omwe ali ndi kutentha kwambiri m'madera ena, ogwiritsa ntchito angafunikire kusankha mafuta achisanu ndi ma viscosity otsika.

2. Mafuta amafuta

Chifukwa cha kusiyana kwakukulu kwa kutentha m'madera osiyanasiyana, injini imayenera kusintha mafuta ndi kalasi yoyenera polowa m'nyengo yozizira.Chifukwa cha kutentha kwambiri kum'mwera, kugwiritsa ntchito -10 # mafuta amafuta m'nyengo yozizira amatha kukumana ndi ntchito, pomwe kumpoto, kutentha kochepa kumatha kuchepetsedwa mpaka -30 ℃ kapena pansi chifukwa cha kuzizira kwambiri.Ndibwino kuti owerenga m'malo -35 # mafuta dizilo, ndi kusankha mafuta ndi kalasi yoyenera lolingana ndi kutentha m'madera ena.

3. Zoziziritsa

Kugwiritsa ntchito moyenera koziziritsira kwapadera kwa Volvo kumatha kuchepetsa dzimbiri la ngalande yamadzi ya injini ndikuletsa dzimbiri la ngalande zamadzi, kutsekeka kwa ma radiator chifukwa cha zinyalala komanso dzimbiri la silinda liner.Pakalipano, 50% yankho la katundu ndi 50% madzi oyera osakaniza madzi amagwiritsidwa ntchito kumwera.Kwa madera ozizira kwambiri kumpoto, tikulimbikitsidwa kuti ogwiritsa ntchito agwiritse ntchito chisakanizo cha 60% stock solution ndi 40% madzi oyera.Kutentha kozizira kumeneku kumatha kuchepetsa kuzizira mpaka -54 ℃, komwe kumatha kukwaniritsa zosowa za madera onse a kumpoto.

4. Kusefera kwa mpweya

Kwa madera omwe ali ndi mchenga wolemera komanso malo ovuta, masanjidwe ndi kusintha kwa fyuluta ya mpweya ndikofunikira kwambiri kuti tipewe kuwonongeka koyambirira kwa injini ndikutalikitsa moyo wautumiki wa injini.Ndibwino kuti ogwiritsa ntchito agule fyuluta yolemetsa yomwe ikulimbikitsidwa ndi wopanga, ndipo fyuluta ya mpweya iyenera kukonzedwa pamalo pomwe sikophweka kudya phulusa, ndipo fyuluta ya mpweya iyenera kusinthidwa malinga ndi alamu ya alamu ya air filter. .

Injini yosungira nthawi yayitali

Kwa injini zina zomwe zimafunikira kusindikizidwa kwa nthawi yayitali, zovuta zina ziyenera kutsatiridwa:

*Gwiritsani ntchito zoziziritsa kukhosi zomwe zimakwaniritsa zofunikira pakugwirira ntchito, apo ayi pangakhale chiwopsezo cha kusweka kwa chisanu.

* Lumikizani cholumikizira batire ndikulipiritsa batire pafupipafupi.

* Njira zothana ndi dzimbiri ziyenera kutengedwa pamalumikizidwe ndi magawo amagetsi.

*Paipi yotulutsa utsi iyenera kuphimbidwa kuti injini isawonongeke kwambiri chifukwa cha madzi amvula kapena zinthu zakunja.

*Kwa omwe asungidwa kwa miyezi yopitilira 8, mafuta a injini ndi fyuluta azisinthidwa, ndipo ntchito yolimbana ndi dzimbiri iyenera kuchitika pafupipafupi.

*Chonde onani Buku la wogwiritsa ntchito kuti muyambitsenso injini.
