Enqubweni yokusebenza kwenjini, uma umfutho kawoyela ungaphansi kuka-0.2Mpa noma ngokushintsha kwejubane lenjini futhi uphakeme futhi uphansi, noma wehla ngokuzumayo waba ku-zero, ngalesi sikhathi kufanele ume ngokushesha ukuze uthole isizathu, ukuxazulula inkinga ngaphambi kokuqhubeka ukusebenza, ngaphandle kwalokho kuzoholela ekushiseni kwe-tile, isilinda nezinye izingozi ezinkulu.
Ngakho-ke, ekusetshenzisweni kwenjini, kufanele sinake kakhulu ingcindezi kawoyela.
Manje izizathu eziyinhloko zengcindezi kawoyela ephansi nezixazululo zichazwa kanje:
1. Uwoyela onganele: uma uwoyela enganele, uzonciphisa inani lamafutha empompini yamafutha noma empompini ngaphandle kwamafutha ngenxa yokungena komoya, okuholela ekwehleni komfutho kawoyela, i-crankshaft kanye ne-bearing, i-cylinder liner kanye ne-piston izothuthukiswa ngokumpofu. ukugcoba nokugqokwa.
Izinga likawoyela epanini likawoyela kufanele lihlolwe ngaphambi kokushintsha ngakunye ukuze kuqinisekiswe umthamo wamafutha owanele.
2. Uma izinga lokushisa lenjini liphezulu kakhulu, isikali sesistimu yokupholisa injini sibucayi, umsebenzi uphansi noma injini ilayishwe ngokweqile isikhathi eside, noma isikhathi sokuphakelwa kukawoyela sephampu yokujova uphethiloli sekwephuze kakhulu, kuyokwenzeka. kubangela ukuthi umzimba ushise ngokweqile, okungagcini nje ukusheshisa ukuguga nokuwohloka kwamafutha, kodwa futhi kwenza amafutha ahlanjululwe kalula, okuholela ekulahlekelweni okukhulu kokucindezela kwamafutha okuvela ekukhishweni.
Isikali kufanele sikhishwe epayipini lesistimu yokupholisa;
Lungisa isikhathi sokuphakelwa kukaphethiloli;
Gcina injini isebenza ekulayisheni kwayo okulinganiselwe.
3. Iphampu kawoyela iyeka ukusebenza: uma iphinikhodi engaguquki yegiya lokushayela kanye ne-shaft yokushayela yepompo yamafutha inqanyuliwe noma ukhiye wokukhwelana uwa;
Futhi umzimba wangaphandle wokumunca iphampu kawoyela uzopompa igiya likawoyela elibambekile.Izobangela ukuthi iphampu kawoyela iyeke ukusebenza, umfutho kawoyela nawo uzokwehla ube nguziro.Amaphini noma okhiye abalimele kufanele bashintshwe;
Isihlungi kufanele sibekwe endaweni yokudonsa yephampu kawoyela.
I-4, ukuphuma kukawoyela wephampu kawoyela akwanele: lapho imvume phakathi kwe-shaft yepompo yamafutha kanye ne-bushing, imvume phakathi kobuso bokuphela kwegiya kanye nesembozo sepompo, ukucaciswa kohlangothi lwezinyo noma imvume yomsakazo idlula okuvunyelwe. ukubaluleka ngenxa yokugqoka, kuzoholela ekunciphiseni amafutha epompo, okuholela ekwehleni kokucindezela kokugcoba.
Izingxenye eziphelelwe ukubekezelelana kufanele zishintshwe ngesikhathi;
Gaya ingaphezulu lekhava yephampu ukuze ubuyisele imvume ngobuso bokuphela kwegiya bufinyelele ku-0.07-0.27mm.
5. I-crankshaft kanye ne-bearing fit clearance inkulu kakhulu: lapho injini isetshenziswa isikhathi eside, i-crankshaft kanye nenduku yokuxhuma i-fit clearance iyanda kancane kancane, ngakho-ke i-wedge kawoyela ayakhiwe, futhi umfutho kawoyela nawo uyancipha.
Kunqunywa ukuthi uma igebe likhuphuka ngo-0.01mm, umfutho kawoyela uzokwehla ngo-0.01Mpa.
I-crankshaft ingapholishwa futhi induku yokuxhuma enosayizi ohambisanayo ingakhethwa ukuze kubuyiselwe imvume efanelekile ezingeni lobuchwepheshe.
I-6, isihlungi samafutha sivinjiwe: lapho amafutha evinjiwe ngenxa yesihlungi futhi engakwazi ukugeleza, i-valve yokuphepha etholakala phansi kwesihlungi ivuliwe, amafutha ngeke ahlungwe futhi aqonde ngqo esiteshini samafutha esikhulu.
Uma ingcindezi yokuvula i-valve yokuphepha ilungiswa kakhulu, lapho isihlungi sivinjiwe, asikwazi ukuvulwa ngesikhathi, ukuze ukucindezela kwepompo yamafutha kwanda, ukuvuza kwangaphakathi kuyanda, ukunikezwa kwamafutha kwe-passage enkulu yamafutha. iyancipha ngokuhambisanayo, ibangele umfutho kawoyela wehle.Njalo gcina isihlungi sikawoyela sihlanzekile;
Lungisa kahle ukucindezela kokuvula kwe-valve yokuphepha (ngokuvamile i-0.35-0.45Mpa);
Faka esikhundleni ngesikhathi sentwasahlobo ye-valve yokuphepha noma indawo yokuhlangana yebhola lensimbi yokugaya kanye nesihlalo sokubuyisela ukusebenza kwayo okuvamile.
7. Ukulimala noma ukwehluleka kwe-valve yokubuyisela uwoyela: Ukuze kugcinwe ukucindezela kwamafutha okuvamile endaweni enkulu yamafutha, i-valve yokubuyisela uwoyela inikezwa lapha.
Uma isiphethu se-valve yokubuyisela uwoyela sikhathele futhi sithambile noma silungiswa ngendlela engafanele, indawo yokuhlangana yesihlalo se-valve nebhola lensimbi ligqokwa noma libhajwe ukungcola futhi livalwe ngokukhululekile, inani lokubuya kwamafutha lizokhula kakhulu, futhi ukucindezela kwamafutha okuyinhloko. ukudlula uwoyela nakho kuzokwehla.
I-valve yokubuyisela uwoyela kufanele ilungiswe futhi ukucindezela kwayo kokuqala kulungiswe phakathi kuka-0.28-0.32Mpa.
8, irediyetha kawoyela noma ukuvuza kukawoyela wepayipi: ukuvuza kukawoyela kuyinjini engcolile, futhi kuzokwenza umfutho kawoyela wehle.
Uma ipayipi livinjwe ukungcola, lizophinde linciphise ukugeleza kukawoyela ngenxa yokwanda kokumelana, okuholela ekwehleni komfutho kawoyela.
Irediyetha kufanele ikhishwe, ishiselwe noma ishintshwe, futhi ingasetshenziswa ngemva kokuhlolwa kwengcindezi; Sula ukungcola kwamapayipi.
I-9, ukwehluleka kwegeji ye-pressure gauge noma ukuvinjwa kwamapayipi kawoyela: uma ukwehluleka kwegeji yokucindezela, noma ukusuka esiteshini esikhulu samafutha kuya epayipini likawoyela wegeji lokucindezela ngenxa yokuqoqwa kokungcola nokugeleza akusheleli, ukucindezela kukawoyela kuzokwehla ngokusobala.
Lapho injini ibambezela ngesivinini esiphansi, khulula kancane kancane ilunga leshubhu, thola indawo enephutha ngokuvumelana nesimo sokugeleza kukawoyela, bese ugeza ishubhu noma ushintshe igeji yokucindezela.
10. I-pan yokudonsa uwoyela ivinjiwe, okuholela ekutheni i-pressure gauge pointer ikhuphuke futhi yehle.
Ngokuvamile inani legeji yomfutho kawoyela kufanele libe phezulu ku-throttle enkulu kunase-throttle encane, kodwa ngezinye izikhathi kuzoba nezimo ezingavamile.
Uma amafutha engcole kakhulu futhi enamathela, kulula ukuvimba ipani lokumunca uwoyela.Lapho injini isebenza ngesivinini esiphansi, ngenxa yokuthi ukumunca uwoyela wepompo kawoyela akukukhulu, isiteshi samafutha esiyinhloko sisengakwazi ukusungula ukucindezela okuthile, ngakho ukucindezela kwamafutha kuyinto evamile;
Kepha lapho i-accelerator isebenza ngesivinini esikhulu, ukumuncwa kukawoyela kwephampu kawoyela kuzoncishiswa kakhulu ngenxa yokumelana ngokweqile kwe-sucker, ngakho-ke inani lenkomba yegeji yomfutho kawoyela liyehla ngenxa yokungatholakali kukawoyela okwanele emafutheni amakhulu. iphaseji.Ipani lamafutha kufanele lihlanzwe noma kushintshwe uwoyela.
I-11, uhlobo lwamafutha alulungile noma ikhwalithi ayifanelekile: izinhlobo ezahlukene zenjini kufanele zengeze uwoyela ohlukile, imodeli efanayo ngezinkathi ezahlukene zonyaka kufanele futhi isebenzise izinhlobo ezahlukene zamafutha.
Uma i-brand engalungile noma engalungile, injini izosebenza ngoba i-viscosity yamafutha iphansi kakhulu futhi ikhulise ukuvuza, ukuze umfutho wamafutha uyancipha.
Amafutha kufanele akhethwe ngendlela efanele, Futhi ngezinguquko zonyaka noma izifunda ezihlukene ukukhetha uwoyela ngokunengqondo.
Ngesikhathi esifanayo, izinjini zikadizili kufanele zibe uwoyela we-diesel, hhayi uwoyela kaphethiloli.
