Maitiro Ekuita Hupenyu HweSevhisi yeCummins Supercharger

Nekuti iyo yakatemerwa kukurumidza kushanda kweCummins engine supercharger inodarika 130,000 rpm, uye iri pakubuda kwepopotera manifold, tembiricha yakakwira zvakanyanya (pamusoro pe800 ° C), uye inlet uye exhaust pressure zvakare yakakura, yakakwira. tembiricha, high pressure uye high speed.Naizvozvo, zvinodikanwa zvekuzora, kutonhora uye kuiswa chisimbiso kweiyo supercharger zvakakwirira.

Kuti uve nechokwadi chehupenyu hwesevhisi ye supercharger ye Cummins injini jenareta , zvinodikanwa kuve nechokwadi chekuzora uye kutonhora kweiyo turbocharger inoyangarara inotakura.Panguva imwecheteyo, mukushandiswa, inofanirwa ku:

a.Injini inofanira kushanda kwemaminitsi 3-5 mushure mekutanga.Usawedzera mutoro nekukurumidza kuti uve nechokwadi chekuzora zvakanaka kweiyo supercharger.Chikonzero chikuru ndechekuti supercharger iri pamusoro peinjini.Kana supercharger ikatanga kumhanya zvine spidhi injini yangotanga, zvinokonzeresa kuti mafuta emafuta atadze kukwira nekufamba kwenguva kuti ape mafuta kune supercharger, zvichikonzera kuparara kwemafuta e supercharger, uye kutopisa iyo supercharger yese. .

b.Nguva yekusashanda haifanirwe kunge yakareba, kazhinji isingapfuuri maminetsi gumi.Kana iyo nguva yekusaita yakarebesa, inokonzeresa kudonha kwemafuta pakupera kwe compressor.

c.Usadzima injini pakarepo usati wamira.Inofanira kunge iri idling kwemaminetsi matatu-5 kuderedza kumhanya kwe supercharger uye tembiricha ye exhaust system kudzivirira kupisa kudzoreredza-oiri coking-kupisa kupisa uye kumwe kukanganisa.Kuwanzoshandisa zvisirizvo kunogona kukuvadza supercharger.

d.Injini dzenguva refu dzisina kushandiswa (kazhinji dzinopfuura mazuva manomwe), kana injini dzine supercharger nyowani, dzinofanirwa kuzadzwa nemafuta pakupinza kweiyo supercharger isati yashandiswa, zvikasadaro hupenyu hunogona kudzikiswa kana iyo supercharger inogona kukuvara nekuda kwekusagadzikana kwemafuta.

e.Nguva dzose chengetedza kana zvikamu zvekubatanidza zvakasununguka, kuputika, kupera kwemafuta, uye kana pombi yekudzoka haina kuvharwa, kana iripo, inofanira kubviswa panguva.

f.Chengetedza sefa yemhepo yakachena uye gara uchiitsiva sezvinodiwa.

g.Gara uchishandura mafuta nemafuta sefa.

h.Gara uchitarisa radial axial clearance ye turbocharger shaft.Iyo axial clearance haifanirwe kunge inopfuura 0.15 mm.Iyo radial clearance ndeye: iyo clearance pakati peimpeller uye yekumanikidza goko haifanirwe kuve isingasviki 0.10 mm.Zvikasadaro, inofanira kugadziriswa nenyanzvi kudzivirira kurasikirwa.
