Zifukwa Zazikulu Zakuchepetsa Mphamvu ya 600kw Volvo Genset

Pamene 600kW Volvo genset akugwira ntchito, mbali zambiri Wopanda kapena atembenuza ndi pa liwiro mkulu pansi katundu wina, monga pisitoni ndi yamphamvu liner, crankshaft ndi kubala, etc. nthawi yogwira ntchito, malo okhudzana ayenera kuvala chifukwa cha kukangana, komwe kumawononga pang'onopang'ono kukula koyambirira ndi geometry.Kuvala kwachibadwa kumeneku nthawi zambiri kumatchedwa kuvala kwachilengedwe, komwe kumakhala kosapeweka.

Kuonjezera apo, kutentha m'chilimwe kumakhala kwakukulu ndipo chinyezi chamlengalenga chimakhala chokwera kwambiri.Nyengo iyi m'chilimwe ndiyosavuta kuyambitsa zovuta zina pakugwira ntchito kwa jenereta ya dizilo:

1. M'chilimwe, liti 600kW jenereta ya dizilo ntchito, kuchuluka kwa mpweya mu mlengalenga adzakhala wocheperapo kuposa masiku onse.Kumayambiriro kwa pampu yamafuta a injini ya dizilo ndi yayikulu kwambiri kapena yaying'ono kwambiri, zomwe zimapangitsa kuti mafuta asatenthedwe.Mwa njira iyi, n'zosavuta kuchepetsa kuyaka kwa mafuta, motero kumakhudza mphamvu.

2. M'chilimwe, kutentha kumakhala kwakukulu ndipo kutentha kwa madzi kumakhala kosavuta kukwera, zomwe zimabweretsa kuchepa kwa kutentha kwa 600kW jenereta ya dizilo, ndipo mphamvu imakhudzidwanso.Kuphatikiza apo, chinyezi chambiri mumlengalenga m'chilimwe chidzakhudza mpweya wa fyuluta ya jenereta ya dizilo, zomwe zingayambitsenso kuchepa kwa mphamvu ya unit.

3. Kuyera kwa mafuta amafuta sikuli kwakukulu ndipo kutentha kwa moto sikuli kwakukulu.Pankhaniyi, m'malo ndi mafuta dizilo enieni.

4. Ngati mafuta opangira injini sakugwiritsidwa ntchito molondola, mafuta a injini omwe ali ndi kusinthasintha kwakukulu ayenera kugwiritsidwa ntchito m'chilimwe, zomwe sizili zophweka kuwononga injini ya dizilo.

5. Fyuluta ya mpweya imatsekedwa kapena yodetsedwa, zomwe zimapangitsa kuti mpweya usalowe mokwanira, zomwe zimabweretsa kuchepetsa mphamvu.Ogwiritsa amayenera kuyeretsa zosefera za mpweya nthawi zonse kapena kusintha zinthu zosefera, ndi zina.

6. Fyuluta yamafuta imatsekedwa kapena yodetsedwa, ndipo kuchuluka kwa jekeseni wamafuta sikukwanira, kotero mphamvu imachepa.Zosefera zitatu zamafuta (sefa ya mpweya, zosefera zamafuta ndi zosefera zamafuta) za dizilo ziyenera kutsukidwa pafupipafupi kuti makinawo agwire bwino ntchito.Mukamagwiritsa ntchito kwakanthawi, sinthani zinthu zosefera kapena fyuluta yonse ngati pakufunika.

7. Chifukwa china chotheka cha kuchepa kwa mphamvu ya unit ndi nthawi yolakwika yoyatsira, yomwe iyenera kusinthidwa.

Posachedwapa, ogwiritsa ntchito ena anena kuti mphamvu ya jenereta ya dizilo imachepa kapena mphamvu idzakhala yotsika kuposa kale pambuyo pokonzanso.Chifukwa chiyani?Dingbo mphamvu yakusanthulani.

Chifukwa cha kuchepa kwa mphamvu ya jenereta ya dizilo ingakhale kuti pali malire okhwima a kusakanikirana kwa zigawo za jenereta za dizilo.Pambuyo pokonza zolakwika ndi kuyesa musanachoke ku fakitale, ikhoza kukwaniritsa mafuta abwino kwambiri komanso mphamvu ya jenereta ya dizilo.

Pambuyo pa kukonzanso, fyuluta ya mpweya ikhoza kukhala yodetsedwa, mbali yopangira mafuta ndi yayikulu kwambiri komanso yaying'ono kwambiri, chitoliro chotulutsa mpweya chimatsekedwa, pisitoni ndi cylinder liner zimaphwanyidwa, dongosolo lamafuta ndilolakwika, gulu la silinda ndilolakwika, Makina ozizirira komanso opaka mafuta ndi olakwika, ndipo pamwamba pa shaft ya ndodo yolumikizira ndi crankshaft yolumikizira ndodo imawumbidwa.

Momwe mungathetsere kuchepa kwa mphamvu ya injini ya dizilo mutatha kukonzanso?

Yankho lake ndi losavuta.Ngati fyulutayo ilibe yoyera, yeretsani pakati pa dizilo la mpweya wa dizilo ndikuchotsa fumbi pa pepala losefera.Ngati ndi kotheka, sinthani chosefera ndi china chatsopano.Kuthetsa vuto la kutsekeka kwa chitoliro cha utsi: choyamba, timayang'ana ngati pali fumbi lambiri lomwe limakhala mu chitoliro cha utsi wa jenereta ya dizilo.Nthawi zambiri, kuthamanga kumbuyo kwa chitoliro cha utsi sikuposa 3.3kpa.Kawirikawiri, nthawi zonse tikhoza kumvetsera kuyeretsa fumbi la chitoliro chapansi cha utsi.Ngati mafuta ali okulirapo kapena ochepa kwambiri, tiyenera kuyang'ana ngati zomangira za jekeseni wa jekeseni wamafuta ndizotayirira, Masulani zofunikira pakuyika shaft yamafuta a injini ndikumangitsa zomangira.
