Tachometer - kuba yinxalenye wemoto yonke

Tachometer - kuba yinxalenye yemoto nganye. Esi sixhobo isetyenziselwa ukugqiba inani yeenguqu yenjini, xabiso lazo elo ke ofakwe isikali okhethekileyo. Njengoko umthetho, inkqubo yokulinganisa kwenzeka ngendlela kwimizuzwana embalwa, ukuze ukuba umqhubi uyakwazi ukufumana kuphela inkcazelo enokuthenjwa imeko yangoku "injini" emotweni. Iyunithi ekhethekileyo "tachometer" kwaye isebenza njani, fumana kwinqaku namhlanje bethu.

imisebenzi

Umsebenzi iphambili yale sixhobo - kukho isiqabu ekukhetheni ezifunekayo (okanye mandithi ekunene) kwibhokisi transmission switch, ukuze kwandiswe kakhulu zabafaki isithuthi kungekhona nje "ukubandezeleka" motor. Afikayo ngereferensi: injini zancitshiswa okanye ukwanda iziphumo ngesantya umthwalo enkulu kuzo zonke iindawo igeza, ukuze ubomi motor kunye gearbox liyehla kakhulu. Ngoko ke, lo tachometer - uhlobo "lomcebisi", nto leyo ibonisa ukuba umqhubi isantya yangoku injini, ngoko kubonisa imfuneko kunokwenzeka ukutshintshela kwisantya ephakamileyo okanye elisezantsi (ngokufanelekileyo, xa inaliti iwile okanye uye ngaphaya kwisikali green).

isimiso ukusebenza

Umongo kwisixhobo efana tachometer, - irejista yolawulo kunye nenani la ukusuka woluvo crankshaft. Oku kunye nabenzi boluvo, ngoko musa ukucinga ukuba intambo tachometer eso inxeba ndaweni ithile phaya phandle crankshaft, okanye enye into. Kananjalo kubalulekile ukuba siqaphele ukuba ubume count iya kwenziwa kuzo zombini phambili kwaye ngasemva (kwezinye iimeko nkqu kumacala omabini).

Ixabiso, nto leyo ilinganiswa ngu menzi woluvo olubonisayo ngomlinganiselo okhethekileyo. Apha, yokulinganisa ubuninzi engundoqo inani revolutions ngamnye (Rev / min) ngcaciso imfutshane. Ngaloo ndlela ezinxaxhileyo kwezixhobo switsha kummandla revolutions amakhulu ezininzi (kwi kwisikali olinikiweyo ivame kuphelelwa ukususela nge-2 ukuya kwi-8 amawaka yeenguqu / min). zobuchwepheshe, ibonisa ufundo yechaneke ngaphezulu. Hi ndlela leyi, malunga emaXhoseni.

iintlobo

Okwangoku kukho iintlobo ezimbini ezingundoqo izixhobo ezifana tachometer. Oku izixhobo socofo (kwakhona ukubizwa ngokuba analog) kunye nohlobo digital. Uhlobo lokuqala endala kakhulu kwaye ngexesha elifanayo ethembekileyo. Ngaphandle kokuba tachometer digital electronic - kuba ichanile yaye isixhobo esebenza kakhulu ngakumbi, abaqhubi abaninzi bakhetha ukusebenzisa iindlela utolo. Isibakala sokuba ubungqina obungaka Kulula kakhulu ukufunda, lo gama imfuno ixesha ngekhompyutha elide kakhulu ukuba ingasetyenziswa. Kwaye ke utolo ube bubungqina ayichananga, kodwa iluncedo ngakumbi ukufunda. Ke ukuba injini engundoqo yamendu akazange ngaphaya isikali eluhlaza. Yaye isibakala sokuba kukho umahluko ka 100-300 Rev / min, ayikho kakhulu kwaye kakhulu.

isiphelo

Ngoko ke, lo tachometer i iluncedo kakhulu isixhobo sokulinganisa (nangona ayifuneki) ekhawuleza ifundeka isantya crankshaft kwaye ibonisa ezi amaxabiso kwisikali okhethekileyo.
