Injini dzedhiziri dzinogona sei kuita mafuta akawandisa?(二)
2021-08-20
Kuchengetedzwa kwemafuta einjini dzedhiziri kwagara kuri chikamu chakakosha chekuchengetedza mutengo, uye kunogona zvakare kuvandudza zvinobudirira uye nehupenyu hwesevhisi hweinjini dzedhiziri. Muchinyorwa chakapfuura, takatsanangura pfungwa shanu pamusoro peinjini yedhiziri-yekuchengetedza mafuta uye nzira dzekudzivirira, uye inotevera ndiyo yakasara, uye zvakare inoshanda kwazvo nzira.
6) Gadzirisa kudzvanywa kwejekiseni yemafuta yeinjector yemafuta. Semuenzaniso, iyo jekiseni jekiseni rinomanikidza (12.0 + 0.05) MPa yemafuta jekiseni ye195 injini yedhiziri, kana jekiseni remafuta rakaderera kupfuura 10.0MPa, kushandiswa kwemafuta kuchawedzera ne10 ~ 20g/ (kW. ), iyo nzira yekuenzanisa inogona kushandiswa kutarisa uye kugadzirisa jekiseni kumanikidza. Kumanikidzwa kwepombi yemafuta.
7) Gara uchitarisa uye chengetedza iyo air filter element. Kana iyo air filter element yanyanya kusvibiswa, kutorwa kwemhepo kunenge kusina kukwana. Mhedzisiro yacho yakafanana neiyo isina kururama valve clearance effect. Izvo zvakare zvinotungamira kune yakawedzera injini yedhiziri kushandiswa kwemafuta, simba risina kukwana uye kutadza kweutsi hutema.
8) Kana injini yedhiziri iri kushandiswa, edza kusamhanya nekumhanya kwakazara uye kuzere mutoro zvakanyanya sezvinobvira. Kazhinji, injini dzedhiziri dzine hupfumi hwekushanda. Iyo yakatemerwa kumhanya inomisikidzwa pane nameplate yeinjini, uye zvinoenderana nekuongororwa kwehunhu hweinjini yedhiziri, kumhanya kweiyo yakanakisa hupfumi kushanda ingangoita 85% yekumhanya kwakayerwa. Panguva ino, simba / awa kushandiswa kwemafuta ndiyo yakaderera muhuwandu hwese hwekumhanya. Injini yedhiziri tachometer inomisikidzwa nenzvimbo yakasvibira, inova kazhinji inzvimbo yehupfumi yeinjini yedhiziri.
9) Kudzora tembiricha yemvura inotonhorera. Tembiricha yemvura yakadzikira zvakanyanya kana yakanyanya kukonzeresa kukuvadza kwakaipisisa kumainjini edhiziri. Kana tembiricha yemvura yakadzikira zvakanyanya panguva yekushanda, kubvumidzwa kwakafanana kwezvikamu zvinofamba zveinjini yedhiziri kuchachinja zvakanyanya kubva pakugadziriswa kwedhizaini, izvo zvichawedzera kumhanyisa kumhanya uye kukurumidza kukurumidza kupfeka kweinjini yedhiziri. (Semuyenzaniso, kana tembiricha yemvura yadzikira pane 30 ℃, inodarika kashanu dzenguva dzose kusakara uye kubvaruka, izvo zvinowedzera kushandiswa kwemafuta ne15%). Kana tembiricha yemvura yakanyanyisa, ichaita kuti injini yedhiziri iwedzere kupisa, shandura gapu rechikamu chimwe nechimwe, kukonzera matambudziko akadai sekudonha kwemafuta, piston inonamatira kune cylinder, kudonha kwesimba, nezvimwe. chengetedza tembiricha yemvura ichimhanya mumhando ye80 ~ 90 ℃.
10) Isa injini yedhiziri yekupisa mudziyo painjini yedhiziri. Kushandisa injini dzedhiziri munguva yechando, kuitira kuchengetedza mafuta uye kuderedza kushandiswa kwesimba, injini yedhiziri inotanga kupisa kuburikidza nepombi yekupisa kuti iwedzere kutonhora kwedhiziri uye kuderedza viscosity ye dizeli, kuitira kuti dizeli rive neatomu uye rinopisa zvakakwana. Izvi zvinogona kuderedza zvakanyanya kushandiswa kwemafuta ne5% ~ 10%. Iyo yakanyanya tembiricha yedhiziri preheating ndeye 66 ~ 75 ℃, uye mhedzisiro yacho ndiyo yakanyanya kunaka.
