Tachometer imoto: Iintlobo sabelo

Car tachometer - isixhobo esetyenziselwa ukumisela inani revolutions yamalungu ejikelezayo injini ukusebenza. Isikali lwenziwa nganye ixesha unit okanye ngokutsho isantya intshukumo yomgama. imoto Tachometer kunceda ekukhetheni ukosuleleka ekunene, yaye ngenxa yoko lwenze ubomi yeyunithi yamandla. Oku kuthetha ukuba ngexesha xa isalathisi isixhobo lisondela ummandla ebomvu, kufuneka ngoko nangoko switsha izixhobo ephezulu. imoto tachometer isoloko isetyenziswa kumsebenzi ulungiso: kwi ninganqeni, kunye nenjongo kolawulo yokusebenza isantya shaft motor xa uhambisa umatshini. Umgaqo okusebenzela kwisixhobo onjalo ukuba babhale la mandla avela nabenzi boluvo. Ngaphezu koko ubala inani lazo, imoto tachometer ubhala ngendlela bamkelwa, kwaye ibala ikhefu phakathi pulses. Ngaloo ngokwayo ubale zingenziwa njenge ndlela ngqo, kwaye umva, yaye ukuba kuyimfuneko, ugalelwe, ngamanye macala omabini.

Ngenxa yoko, amanani ifunyenwe senziwa similise ixabiso eliphezulu, ezifana imizuzwana, imizuzu, iiyure, mitha, njl Ukuba kuyimfuneko, imoto tachometer kungaba reset, ngaloo ndlela kwakhona onke amaxabiso eziqokelelweyo. Nangona kunjalo, ukusetyenziswa kwezixhobo ezinjalo kufuneka kukhunjulwe ukuba lokuchaneka kwedatha elilinganiselweyo kunokuba enemiqathango kunye nama-500 Rev / min, xa intle bezixhobo zombane lufikelela 100 Rev / min.

speedometers Car ezi ndidi mbini: analog idijithali.

izixhobo Digital kwenziwa ngohlobo yoboniso elektroniki ebonisa zonke iinkcukacha ukubalwa, oko kukuthi inani amathuba ye-injini nesibili. Loo tachometer iluncedo kakhulu xa ekwenzeni umsebenzi hlengiso kunye unit ucinezelo esekhompyutheni iinjini imoto kunye nokufakwa beminyango kwi economizer et al.

izixhobo Analog ithandwa kakhulu kushishino ngomatshini. Ibonisa inani revolutions ye unit samandla ngokusebenzisa dial iswitshi. Umsebenzi kwisixhobo eso yenziweyo umgaqo-elektroniki. Oku kuthetha ukuba lo umqondiso ovela zincwadi Womenzi ibekwe kwi shaft ngeemoto idluliselwe nj. Le yokugqibela icwangcisa intshukumo isalathisi (iintolo) kwisikali izidanga. Nasiphi na isixhobo izithuthi analog tachometer ukuba injini yomsebenzi kumgaqo. Eyokuqala i elula ukubetha counter inkqubo yombane injini. Kuxhomekeke isantya ojikeleza ngaso le crankshaft. Tachometers injini iinjini sixoxe ngamaza ombane, kodwa "ulwazi" zifumana ngqo zokukhanya coil magdino, leyo udlala indima yokuba generator.

Noba imoto ixabisa kwaye ngaphezu babe tachometer yedijithali. Iza kuba luncedo ngolawulo angoongantweni ukuvavanya ukusebenza iyunithi yolawulo economizer, kwakunye ukuchaneka izixhobo rhoqo analog. Oku kungenxa eliphezulu kumlinganiselo accuracy izixhobo zedijithali. Noko ke, xa isithuthi kubhetele ukusebenzisa isixhobo isalathisi, njengoko kubonakala ngakumbi ukuba umqhubi.
