I-Hydraulic Valve Lift: Ukusebenza, Ukugcinwa kanye Nentengo

Inombolo Okubalulekile ekusebenzeni kahle kwenjini yakho, iziphakamisi ze-hydraulic valve ziqinisekisa ukuxhumana phakathi kwe-camshaft nama-valve ngesenzo sekhamera. Aqukethe amakamelo amabili lapho uwoyela wenjini ucindezelwa khona.

🚗 Isetshenziselwani i-hydraulic lift?

Le i-hydraulic lift ingxenye yemoto evumela ukuthi ubophecamshaft и ama-valve imoto. Kunezinhlobo ezahlukene zeziphakamisi zama-valve ezinama-hydraulic, kodwa ngokuvamile zinamakamelo amabili abamba umfutho kawoyela wenjini.

Ngempela, igumbi eliphezulu lihlala lixhumene ne-camshaft futhi lislayida ekamelweni eliphansi elithinta i-camshaft. isiqu se-valve... Amakamelo amabili axhumana nomunye ngokusebenzisa umzila oqukethe i-valve yokulawula ukucindezela.

Ngakho, lapho i-hydraulic valve lifter iphumule ngakho-ke ufikile ayicindezeli kuwo, amakamelo amabili axoshwa ukucindezela kwamafutha ajikeleza ku-valve. Ngakho-ke, akukho ukudlala phakathi kwekhamera ne-valve.

Ngokuphambene, lapho isiphakamisi se-valve esebenza ngogesi sisebenza futhi ngenxa yalokho ikhamera icindezela ngokumelene naso ukuze ivule ivalvu, ivalvu iyavala futhi ivimbele igumbi elingaphezulu ukuthi lingasheleli liye egumbini elingaphansi ngenxa yokucindezela kukawoyela. I-valve ye-hydraulic icindezela i-valve ukuyivula.

???? Yiziphi izimpawu ze-HS hydraulic valve lifter?

Uma i-hydraulic pushers yakho athunjiwe ou enesicikhona niyakuzwa eshaya izandla enjinini.

Uma umsindo wokuchofoza uvela kuphela lapho kubanda futhi unyamalale lapho kushisa, nakanjani ukunakekela ukukhishwa amafutha omgibeli. Ungasebenzisa isithasiselo esikhethekile emafutheni akho ukuze ukhulule iziphakamisi zamavalvu ezinama-hydraulic.

Uma umsindo wokuchofoza uphikelela noma kushisa, inkinga ngokungangabazeki i-valve engalungile... Ngemuva kwalokho, kuzodingeka ushintshe ama-tappet we-hydraulic.

Iseluleko esizenzakalelayo : Ukwandisa impilo yesiphakamisi se-hydraulic valve, kunconywa ukusebenzisa kuphela uwoyela wenjini osezingeni futhi ogunyaziwe. Futhi khumbula ukushintsha uwoyela njalo ukuze ugweme ukuvala injini kanye neziphakamisi zamavalvu ezinama-hydraulic.

🔧 Ungashintsha kanjani i-hydraulic valve lift?

Ukushintsha i-hydraulic valve lifter kuwumsebenzi oyinkimbinkimbi odinga ukuhlakazwa kwenjini. Uma ungahlomile kahle noma ungeyena uchwepheshe wemishini, asikweluleki ukuthi uguqule i-valve ye-hydraulic valve ngokwakho.

Kuyadingeka

• Amagilavu ​​wokuvikela
• Izibuko zokuphepha
• Qedela amathuluzi
• isixhumi
• I-torque wrench
• Amafutha omshini

Isinyathelo 1: Setha injini ibe phezulu esikhungweni esifile (TDC).

Isikhungo esiphezulu esifile sibonisa indawo lapho ipiston ifinyelela khona endaweni ephakeme kakhulu yokushaywa kwayo kusilinda. Sebenzisa isondo lesandla ukuthola indawo yamaphistoni akho.

Ukuze ushintshe ukuma kwamaphistoni, sebenzisa igiya lesi-3, bese uphakamisa isondo ngojeke bese ekugcineni uphendulela isondo ngokwewashi. Khona-ke uzobona ukuthi izingalo ze-rocker zisebenza kanjani futhi ama-pistons ahamba. Vula kuze kube yilapho ipiston yokuqala iphezulu.

Isinyathelo sesi-2. Susa ibhande lesikhathi.

Nqamula ibhande lesikhathi ku-camshaft pulley ngokukhulula i-tensioner pulley. Ukuze wenze lokhu, uzodinga ukususa umlindi webhande.

Isinyathelo sesi-3: Khipha ikhava yekhanda yesilinda.

Khumula amantongomane uvikele ikhava yekhanda yesilinda bese uyasikhipha. Qaphela ukuthi ungalahleki noma ungalimazi isilinda sekhanda gasket uma ufisa ukuphinda uyisebenzise.

Isinyathelo sesi-4: Hlukanisa i-camshaft.

Khumula amantongomane amabili ngesikhathi, kancane kancane uwaxege elinye ngesikhathi. Unganqamuli ngokuphelele ibhawudi elilodwa ngaphandle uma elinye lishaywa. Ngemuva kokukhipha ama-bolts, ama-bearings kanye ne-camshaft angasuswa.

Ukunakwa : Qaphela ukuthi ungahlanganisi ama-bearings njengoba kufanele ahlanganiswe ngendlela efanele. Ngempela, izigaba zibaliwe.

Isinyathelo sesi-5: Faka esikhundleni isiphakamisi sevalvu ye-hydraulic enesici

Manje njengoba i-camshaft isikhishiwe, ungagcina ususe iziphakamisi zamavalvu ezingasebenzi kahle bese ufaka esikhundleni sazo iziphakamisi ezintsha zama-hydraulic valve. Qiniseka ukuthi ucwilisa iziphakamisi ezintsha zama-hydraulic valve emafutheni ukuze uzigcwalise kabusha ngaphambi kokuzifaka.

Beka iziphakamisi ze-hydraulic valve engxenyeni lapho uthintana nekhamera ukuvimbela ukuvuza kukawoyela nokuphuma kwevalvu.

Isinyathelo 6. Hlanganisa izingxenye ezihlukahlukene zenjini.

Uma ompompi abasha be-hydraulic sebesendaweni, ungahlehlisa izinyathelo ukuze uhlanganiswe kabusha. Sebenzisa i-torque wrench ukuze uqinise ku-torque efanele.

Ngemva kokuhlanganisa yonke into, vumela injini ingasebenzi cishe imizuzu eyishumi nanhlanu ukuze ikhiphe umoya eziphakamisini zamavalvu asebenza ngamanzi. Futhi khumbula ukuhlola izinga likawoyela wenjini.

Yilokho-ke, amakheshi akho e-hydraulic valve ekugcineni ashintshiwe! Uma injini iqhubeka nokushaya ihlombe kungakhathaliseki ukuthi kwenzekani, kungase kube ngenxa yokuthi iphampu kawoyela ayikukhiqizi umfutho owanele.

Inothi : Njengoba uzokwazi ukungena ngaphakathi enjini ukuze ushintshe ama-valve tappets, kunconywa ukuthi uthathe ithuba lokushintsha i-cylinder head cover gasket, i-tensioner roller, i-camshaft oil seal kanye nebhande lesikhathi ngesikhathi esifanayo uma kunesidingo. .

???? Kubiza malini ukushintsha i-hydraulic valve lift?

Ukushintsha isiphakamisi se-valve kuwumsebenzi oyinkimbinkimbi odinga ukuvula injini. Ngakho-ke, intengo yayo iphakeme futhi iyahlukahluka kusuka kumodeli yemoto kuya kwenye. Ngempela, isilinganiso kusuka ku-200 kuya ku-500 euros buyisela ama-hydraulic distributor pushers.

Bala ingxenye kuphela kusuka ku-20 kuya ku-50 euros i-hydraulic valve lifter. Cabangela ukuphindaphinda intengo ye-hydraulic lift ngenani lamakheshi owadingayo.

Zizwe ukhululekile ukuhlola i-Vroomly okuyigaraji elingcono kakhulu lokuphakamisa amavalvu osebenza ngogesi ngentengo ephansi! Qhathanisa oomakhenikha abahamba phambili endaweni yangakini ngokusekelwe enanini kanye nemibono yamanye amakhasimende ukuze umiselele iziphakamisi zakho zamavalvu ngentengo engcono kakhulu.
