Tachometer - ke kuyingxenye ebalulekile zonke imoto

Tachometer - kuyinto kuyingxenye ebalulekile imoto ngayinye. Le divayisi isetshenziselwa ukucacisa inombolo lenjini ekuvukeleni ukubaluleka elivele ke ngokukhishwa ngezinga ekhethekile. Njengomthetho, inqubo ukulinganiswa okwenzeka millisecond ambalwa, ukuze umshayeli ungathola kuphela ukwaziswa okunokwethenjelwa mayelana nesimo samanje "injini" yemoto. Iyunithi ekhethekile "tachometer" futhi isebenza kanjani, ukuthola isihloko namuhla yethu.

imisebenzi

Umsebenzi oyinhloko kule divayisi - impumuzo lapho ukhetha edingekayo (noma kunalokho ngakwesokudla) ukudluliswa switch ibhokisi, ngaleyo ndlela kwande kakhulu Dynamics imoto hhayi ngokuthi "nokuhlupheka" okungapheli motor. Kufika ukuze uthole inkomba: injini kuyehla noma ukwanda kwemithwalo isivinini imiphumela umthwalo eningi ku zonke izingxenye crank, ukuze ukuphila motor kanye gearbox is kakhulu ziyancipha. Ngakho, tachometer - uhlobo "Umeluleki", okukhombisa ukuthi umshayeli wamanje isivinini injini, futhi ngaleyo ndlela kubonisa isidingo kungenzeka ukushintshela isivinini iphansi noma iphezulu (ngokufanele, uma inaliti uwile noma ayebadlula esikalini oluhlaza).

Umgomo we operation

Ingqikithi idivayisi ezifana tachometer, - irejista ukulawula futhi inani pulses kusukela inzwa crankshaft. Kuyinto ne izinzwa, ngakho ungacabangi ukuthi ikhebuli tachometer is nilimaza endaweni ethile laphaya kwi crankshaft, noma ngisho enye into. Futhi uzinake ukuthi ukubala ishayela engenziwa kuzo zombili phambili nasemuva (ezimweni ezithile ngisho zombili izinkomba).

Value, okuyinto kukalwa the inzwa wakubonisa ngezinga ekhethekile. Lapha, i-main sokulinganisa ubukhulu inombolo linemibhikisho ngomzuzu (rev / iminithi) ngayinye. Ngakho ku ngeziphambeko inkinobho amadivayisi esifundeni linemibhikisho abangamakhulu amaningana (ngesikhathi esikalini kubonakala ngokuvamile ugijime kusuka 2 kuya 8 izinkulungwane linemibhikisho / iminithi). zobuchwepheshe, ubonisa ukufundwa esinembile. By the way, mayelana nezinhlobonhlobo.

izinhlobo

Okwamanje kunezinhlobo ezimbili eziyinhloko amadivayisi ezifana tachometer. Lokhu amathuluzi Ukudayela (futhi uvame ukubizwa ngokuthi analog) kanye nohlobo digital. Uhlobo lokuqala kuyinto endala kakhulu futhi ngesikhathi esifanayo okuthembekile. Naphezu kweqiniso lokuthi tachometer electronic digital - linembile futhi ithuluzi sokusebenza kakhulu, abashayeli abaningi bakhetha ukusebenzisa izindlela umcibisholo. Iqiniso ukuthi ubufakazi ngezinga elingaka Ifundeka kalula kakhulu, kuyilapho isidingo electronic isikhathi eside kakhulu ukujwayela. Futhi ake umcibisholo kube ngubufakazi olungalungile, kodwa elula ukufunda. Futhi injini main yesivinini akazange eqele ngalé esikalini oluhlaza. Futhi iqiniso lokuthi kukhona umehluko 100-300 rev / imiz, akusiyo kakhulu nokunye.

isiphetho

Ngakho, tachometer kuyinto ewusizo kakhulu kudivayisi wokulinganisa (kodwa akudingekile) ukuthi ngokushesha ofunda isivinini crankshaft futhi ubonisa lezi zimiso ngezinga elingelikhulu ekhethekile.
