Cause Analysis uye Solution yeDiesel Jenareta Injector Kukundikana

Diesel injini yemafuta jekiseni inoiswa pamusoro wecylinder musoro, basa racho ndiro mafuta edhiziri muchimiro cheyakakwenenzverwa atomi zvidimbu mukamuri yekupisa uye musanganiswa wemhepo, ichigadzira yakanaka dizeli injini yekupisa kamuri yekamuri, basa renguva refu mukupisa kwakanyanya uye yakakwirira. kudzvanywa uye gasi corrosion nharaunda, iyo yemukati yekumhanyisa kuyerera kwezvikamu zvinofamba zvezvidiki zvemakina tsvina muhuturu uye mafuta akashambidzwa kakawanda.Zviri nyore kupfeka nekuora uye ndechimwe chezvakanyanya kukanganisa mudhiziri injini yemafuta.Nhasi, Dingbo Electric Power, iyo mugadziri jenareta , ichakuzivisa iwe chikonzero chekuongorora uye mhinduro yekutadza kwedhiziri jekiseni.

1.Poor atomization yemafuta injector.

Kana jekiseni remajekiseni ranyanya kuderera, jet gole rinopfeka rine kabhoni, kupera kwechitubu kupera kana kuderera kwe elastic kuchaita kuti jekiseni rivhure mberi, kunonoka kuvhara, uye kuumba chiitiko cheatomization yakaipa yespray. work;Kana iyo yakawanda-cylinder injini yedhiziri simba inodonha, iyo inopfungaira inopfuta, muchina unomhanya ruzha hauna kujairika.Pamusoro pezvo, nekuti donhwe redhiziri rine saizi yakakura kwazvo haigone kupiswa zvizere, inoyerera ichipinda mugango remafuta padhuze nemadziro ecylinder, iyo inowedzera mwero wemafuta, inoderedza viscosity, inokanganisa lubrication, uye inogona kukonzera tsaona yekupisa. walla cylinder.

Mhinduro: jekiseni rinofanira kubviswa kuchenesa, kugadzirisa, kugadzirisa zvakare.

2.Fuel injector kudzoka mutsara wakakuvadzwa.

Kana iyo valve yetsono yakasakara zvakashata kana mutumbi wevhavha wetsono usina kunyatsoenderana nejeko rejekiseni, kudzoka kwemafuta kwejekiseni kunowedzera zvakanyanya, vamwe kusvika 0.1 ~ 0.3kg / h.Kana iyo pombi yemafuta yekudzoka yakakuvadzwa kana kuputika, mafuta ekudzoka acharasika pasina, zvichiguma nemarara.

Nokudaro, pombi yekudzoka inofanira kunge yakasimba uye yakavharwa kuitira kuti mafuta ekudzoka anogona kuyerera zvakanaka mutangi.Kana pombi inodzosera yakabatana nesefa yedhiziri, magumo ayo anofanira kugadzikwa vharuvhu yenzira imwe chete kudzivirira dhiziri musefa kupinda mujekiseni.

3.Needle valve orifice yakawedzerwa.

Nekuda kwekuenderera mberi kwejekiseni uye kukukurwa kwekuyerera kwemafuta ekumanikidza kwakanyanya, gomba revhavhavha yetsono zvishoma nezvishoma rinopfeka rakakura, zvichikonzera kudzikira kwekumanikidza kwejekiseni, chinhambwe chejekiseni chinopfupikiswa, dizeli atomization haina kunaka, uye kabhoni dhipoziti mukati. silinda ichawedzera.

Kugadzirisa: kuvhura kwegomba repini jekiseni rinowanzo kukura kupfuura 1mm, uye bhora resimbi rine dhayamita ye4 ~ 5mm rinogona kuiswa kumucheto kwegomba, uye zvinyoro nyoro nenyundo kugadzira purasitiki yenzvimbo. buri remuromo uye kuderedza aperture.Perforated yakananga jekiseni jekiseni nokuda uwandu makomba, diki aperture, vanogona chete kushandisa high speed simbi ichikuya punch mugomba kuguma zvinyoronyoro kugogodza, kana debugging achiri asina kukodzera, tsono vharafu inofanira kutsiviwa.

4.needle valve kuruma.

Mvura kana asidhi mumafuta edhiziri ichaita kuti vharafu yetsono iite ngura uye inonamira.Mushure mekunge koni yechisimbiso yevharuvhu yetsono yakuvadzwa, gasi rinopisa riri muhumburumbira richaiswawo panzvimbo yakafanira kuti riumbe kabhoni deposit kuitira kuti vharafu yetsono iurawe, uye jekiseni rinorasikirwa nejekiseni rayo, zvichizoita kuti silinda. kurega kushanda.

Solution: vharafu yetsono inogona kuva vaviri mumafuta akashandiswa akadziya kuvira muutsi, wobva wabvisa uye shandisa padhi nejira rakapfava ruoko vice clamp tsono muswe zvishoma nezvishoma, yaikwevera pamafuta akachena, rega vharafu yetsono muchiitiko chemuviri wevharuvhu. kugaya kasingaperi, kusvika vharafu yetsono inokwanisa kubatanidza vharuvhu yeawa yebhiza kubva kumuviri wevharuvhu kuti ibude zvishoma nezvishoma kubva.Kana iyo injector bvunzo isingakodzeri, iyo valve yetsono inofanira kutsiviwa.

5.Kupfeka pamagumo chiso chemuviri wetsono.

Kuguma kweiyo tsono yevharuvhu yemuviri inoguma kumeso neanogara achidzokorodza mafambiro eiyo tsono valve kukanganisa, nguva yakareba inozogadzira gomba zvishoma nezvishoma, nekudaro ichiwedzera kusimudza kwevhavha yetsono, uye kukanganisa kushanda kwakajairwa kwejekiseni.

Solution: tsono muviri anogona kuchekwa kuguyo kuti ukuye ichi magumo chiso, uye ipapo kukuya pamwe yakanaka achikuya paste pagirazi ndiro.

6.Fuel injector uye humburumbira musoro joint gomba leakage mafuta channeling.

Kana iyo jekiseni yemafuta yakaiswa nemusoro wecylinder, iyo kabhoni deposit mugomba rekuisa inofanira kubviswa zvakanyatsonaka.Iyo gasket yemhangura inofanirwa kuve yakati sandara, uye ndiro yeasbestos kana zvimwe zvinhu hazvizoshandiswe kuitsiva, kuitira kudzivirira kushata kwekupisa kana kuvharisa.

Kana iyo washer yemhangura yagadzirwa, inofanirwa kugadziriswa nemhangura zvichienderana nehupamhi hwakatarwa kuti ive nechokwadi chekuti chinhambwe chejekitori chinobuda kunze kwe cylinder head ndege inosangana nezvinodiwa zvehunyanzvi.Uye zvakare, iyo injector pressure plate concave inofanirwa kuisirwa pasi, simbisa kudzivirira unilateral bias, inofanirwa kusimbiswa zvinoenderana neyakatsanangurwa torque zvakaenzana, zvikasadaro musoro weinjector uchave nekuda kwekupokana uye kugadzira mafuta ekufambisa gasi.

7.Needle valve uye tsono gomba rinotungamirira chiso kupfeka.

Kudzokororwa kwekufamba kwevharuvhu yetsono mugomba revharuvhu yetsono, pamwe chete nekupinda kwetsvina uye tsvina mukati. mafuta edhiziri , ichaita kuti iyo inotungamira pamusoro pegomba revhavha yetsono zvishoma nezvishoma ipfeke kuitira kuti gaka riwedzere kana kune zvikweshwa, zvichikonzera kuwedzera kwekudonha kwejekiseni, kudzvanywa kunoderedzwa, huwandu hwejekiseni hwemafuta hunoderedzwa, jekiseni. kunonoka kwenguva, zvichikonzera kutanga kweinjini yedhiziri kwakaoma.

Solution: Kana jekiseni nguva kunonoka yakawandisa, locomotive haigoni kunyange kumhanya, panguva ino inofanira kutsiva tsono vharafu vaviri.

8.Madonhwe emafuta anoonekwa mune jekiseni.

Kana jekiseni riri kushanda, iyo yekuvharisa koni yemuviri wetsono yevharuvhu ichaiswa pasi pesimba rakasimba revhavhavha yetsono, pamwe neiyo yakanyanya kudzvanywa mafuta inoyerera ichigara kubva mujekiseni kunze, iyo koni inozoonekwa zvishoma nezvishoma nick kana mavara, nekudaro. kurasikirwa nechisimbiso, zvichiita kuti madonhwe emafuta ejekiseni.

Kana tembiricha yeinjini yedhiziri yadzikira, pombi yepombi inoburitsa utsi huchena, tembiricha yeinjini inokwira yobva yaita utsi hutema, uye pombi yepombi inobudisa kurira kwepfuti kusingawanzoitiki.Panguva ino, kana mafuta anowanikwa kune silinda akamiswa, ruzha rwekubvisa utsi uye kupfura kunopera.

Solution: jekiseni anogona disassembled, ari tsono vharafu musoro ane zvishoma chromium oxide yakaisvonaka achikuya paste (teerera kwete kunamatira mugomba tsono valve) kukuya koni, uye ipapo kuchenesa nemafuta dhiziri, kupinda muyedzo injector.Kana ichiri kusakodzera, inoda kutsiva tsono valve accessories.

Kana iwe uchifarira majenareta edhiziri, ndapota taura nesu neemail dingbo@dieselgeneratortech.com.Tichapa basa rinonyanya kufunga.
