Chii chinonzi column yepamusoro yevharuvhu yemota?
Hunde yevharuvhu yemota, inowanzonzi vharuvhu tappet kana kuti vharuvhu tapple, chinhu chakakosha muhurongwa hwemavharuvhu einjini. Inonyanya kukonzera kushandura kufamba kwecamshaft kuita kufamba kwemutsara wepamusoro-soro kwemavharuvhu, nokudaro ichidzora kuvhurwa nekuvharwa kwemavharuvhu nemazvo.
Basa Rekutanga:
Semuteveri wekamera, vharuvhu tappet inogamuchira simba kubva paprofile yekamera yoriendesa kupushrod kana kuvharuvhu.
Munguva yekufambiswa kwemafambiro, inofanirawo kutsungirira simba repadivi rinoitwa necam uye kuendesa masimba aya kumusoro we cylinder kana ku engine block kuti ive nechokwadi chekuti vharuvhu inoshanda zvakanaka.
Kurongwa Kukuru:
Tapeti yeMechanical: Chimiro chacho chiri nyore uye mutengo wacho wakaderera, asi chinogona kuburitsa ruzha rukuru panguva yekushanda uye chinoda kugadziriswa kwevharuvhu nemaoko kuti chigadzirise kuwedzera kana kupisa kwacho kuchinge kwawedzera.
Hydraulic Tappet: Inoshandisa kumanikidzwa kwemafuta mukati kuti igadzirise otomatiki, zvichiita kuti vharuvhu isashande, zvichiita kuti ruzha rweinjini ruderere zvakanyanya uye kuti kushanda kwayo kuve nyore. Zvisinei, chimiro chayo chakaoma uye mutengo wakakwira.
Hunhu hweMaumbirwo uye Zvishandiso:
Kuti uderedze huremu, chivharo chevharuvhu chiri muhurongwa hwakaiswa pamusoro pevharuvhu chinowanzogadzirwa sechimiro che cylindrical.
Roller Tappet imhando yakajairika, iyo inoderedza kukweshana uye simba repadivi kuburikidza nechimiro cheroller, zvichivandudza kushanda zvakanaka, asi chimiro chacho chakaoma uye chinoshandiswa zvakanyanya mumamiriro ezvinhu ane mutoro wakawanda senge mainjini edhiziri anotamiswa zvakanyanya.
Zvinhu zvakajairika zvinosanganisira simbi yakakandwa yenickel-chromium alloy, simbi yakakandwa yealloy inotonhorera, kana simbi yakasimba yealloy. Pamusoro pekukweshana panoda kurapwa kwekupisa uye kukuya kwakanyatsonaka kuti pave nekusakara. Tekinoroji yemazuva ano inoshandisawo maitiro ekugadzirisa pamusoro akadai seDLC (Diamond-like Carbon) coating kuti ideredze zvakanyanya friction coefficient.
Kukosha uye Kugadzirisa:
Kushanda kwevharuvhu tappet kunokanganisa zvakananga simba rinobuda muinjini, kushandiswa kwemafuta, uye mwero wekubuda kwemhepo. Kana paine zvikanganiso zvakaita sekusakara, kuchinja, kana kunamira, zvinokonzeresa kuvhurika nekuvharika kwemavharuvhu zvisina kujairika, zvichikonzera kudedera kweinjini, kurasikirwa nesimba, uye kushandiswa kwemafuta kwakawedzera.
Kuti iwedzere nguva yayo yekushanda, kuchinjwa oiri nguva dzose uye kugadziriswa kweinjini zvinodiwa kuti ive nechokwadi chekuti mafuta acho anozorwa zvakanaka.
Chidzitiro chevharuvhu (chinowanzozivikanwa sechidzitiro chevharuvhu) chinhu chakakosha muhurongwa hwechitima chevharuvhu cheinjini. Basa rayo guru nderekushandura kufamba kwecamshaft kuita kufamba kwemutsara wepamusoro-soro kwevharuvhu, nokudaro ichidzora kuvhurwa nekuvharwa kwemavharuvhu ekupinda nekubuda, zvichiita kuti injini ipedzise matanho mana ekupinda, kudzvanywa, kugadzirwa kwesimba, uye kubuda.
Mabasa chaiwo anogona kukamurwa kuita zvinhu zvinotevera:
Kufambisa simba nemafambiro: Inogamuchira zvakananga simba kubva kucamshaft yoriendesa kupushrod kana vharuvhu, zvichiita kuti vharuvhu ivhare panguva yakatarwa.
Kutsungirira simba repadivi: Panguva yekutenderera kwekamera, simba repadivi rinogadzirwa, uye vharuvhu tappet inofanira kutamisa simba iri kuenda kumusoro we cylinder kana ku engine block kuti ive nechokwadi chekufamba kwakasimba.
Kugadzirisa otomatiki kucheneswa kwevharuvhu (rudzi rwehydraulic): Injini dzemazuva ano dzinoshandisa zvakanyanya matepi ehydraulic, ayo akazadzwa nemafuta uye anogona kutsiva otomatiki kucheneswa kwevharuvhu nekuda kwekuwedzera kana kupera kwekupisa, zvichiita kuti "zero clearance" ishande, nokudaro zvichideredza ruzha rweinjini zvakanyanya uye zvichivandudza kushanda kwayo.
Kuderedza zvinodiwa pakugadzirisa: Matepi e hydraulic haadi kugadziriswa kwevharuvhu nemaoko, zvichiita kuti kugadzirisa injini kuve nyore.
Kana vharuvhu yetappet (kunyanya rudzi rwe hydraulic) ikakundikana, zvakaita sekusakara, kubuda kwemafuta, kana kuti mhepo ichipinda mukati, zvinokonzera ruzha "rusina kurongeka" (runonyanya kuoneka muinjini dzinotonhora) uye zvinogona kukonzera kurasikirwa nemagetsi, kuwedzera kwekushandiswa kwemafuta, kana matambudziko emhepo inobuda.
Zvikonzero zvinowanzo sanganisira kumanikidzwa kwemafuta kusina kukwana, huwandu hwemafuta hwakanyanya kukwira kana kuderera zvakanyanya, kana kusimba kwemafuta kusina kuenzana.
Saka, kuchinja mafuta nguva dzose uye kuchengetedza sisitimu yekuzora mafuta yakajairika matanho akakosha ekuwedzera hupenyu hwebasa revharuvhu uye kuona kuti injini inoshanda zvakanaka.
Ndapota ipai rugwaro rwamunoda kuti ndirududzire nemazvo
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
