i-valve spring

Iyini i-valve spring futhi isebenza kanjani?

Kungenzeka ukuthi ujwayelene nendlela isiphethu se-valve esisebenza ngayo ukunika amandla injini yemoto yakho, kodwa lezi ziphethu nazo zidlala indima ebalulekile emhlabeni wobunjiniyela basolwandle.

Uma nje iziphethu zikwazi ukugcina ingcindezi edingekayo, zizokusiza ukuthi ugweme ukwehluleka kwenjini okungazelelwe kanye nokulimala. Ngamafuphi, asiza ukugcina ama-valve akho asebenza kahle.

Kodwa kungaphezu kwalokho.

Qhubeka ufunde ukuze ufunde ngezinkinga i-valve yasentwasahlobo ingasiza ekuvimbeleni, ufunde ngezinhlobo ezahlukene zama-valve entwasahlobo, futhi uqonde ukuthi ungaziqaphela kanjani izimpawu ezivamile zenkinga.

Yenzani ama-valve springs?

Okokuqala, ake sixoxe ngendima edlalwa yi-valve spring emhlabeni wasolwandle.

I-valve spring ibekwe eduze kwesiqu se-valve futhi ibanjwe endaweni yokugcina. Umsebenzi wayo oyinhloko ukulawula sonke isitimela se-valve, ukuqinisekisa ukuthi ukucindezela kwentwasahlobo efanele kusetshenziswa ngokungaguquki ukuvimbela ingxoxo ye-valve.

Njengoba ukugxuma kwe-valve kungaholela ekuhlulekeni okuphelele kwenjini, ukuphelelwa amandla, ngisho nokwehluleka kwe-valve, lezi ziphethu zenza umsebenzi obaluleke kakhulu.

Ukwengeza, isiphethu se-valve yokucindezela futhi sisiza ukuvimbela ukungahambi kahle kwe-valve noma ukuhlukana phakathi kwe-camshaft nesitimela se-valve okwenzeka lapho isivinini senjini sidlula iziphethu ze-valve.

Iziphethu zisiza ukuvikela i-axle, izindonga zesilinda, amapiston namabheringi enjini njengoba ziphoqa amavalvu ukuthi avaleke ngokugcwele ukuze anikeze isilinganiso esidingekayo sokucindezela.

Ziphinde zisize ekuvimbeleni izinkinga ngeziphakamisi ezinama-hydraulic ngokusebenza ngokumelene nokucindezela kukawoyela ku-piston yangaphakathi nokuvimbela i-lift ukuthi ingahambi phezulu.

Izinhlobo zama-valve springs

Njengoba nje kunezinhlobo eziningi zama-valve, kunezinketho eziningi uma kuziwa emithonjeni ye-valve.

Imithombo ye-Conical inohhafu omncane ophezulu, okusho ukuthi isisindo esincane esiphindaphindayo kanye nezinga eliphezulu lemvamisa yemvelo.

Uma ufuna amakheshi aphezulu asabalalisa isisindo kangcono, khetha intwasahlobo yocingo oluyiqanda. Iziphethu zezinyosi nazo zilungele ukunciphisa isisindo nokusabalala, futhi zilungele izinjini eziphakeme ze-rpm.

Iziphethu zekhoyili yizona ezivame kakhulu ukukhetha, kodwa ngokuvamile azikhiqizi ngokwanele ukushayela isitimela sakho se-valve ngendlela efanele.

Izinkinga zentwasahlobo ye-valve?

Ukuze ugweme inhlekelele, udinga kokubili ukutshala izimali ezisekelweni zamavalvu ezisezingeni eliphezulu futhi ufunde ukubona izimpawu zokuqala zenkinga yasentwasahlobo enjinini yakho.

Ukuze wenze lokhu, faka i-vacuum gauge enjinini bese uyivula. Uma ukufundwa kwegeji kuqhubeka nokushintsha ngokushesha njalo uma ukhuphula isivinini senjini, uzokwazi ukuthi ama-valve springs cishe adinga ukushintshwa.

Uma usebenzisa injini yakho njalo ngama-RPM aphezulu, kungenzeka ukuthi isiphethu se-valve sishile, okusho ukuthi isilinda sizovutha kabi ngaso sonke isikhathi.
