I-Tachometer. Ungafunda futhi usebenzise kanjani ubufakazi bakhe?

I-tachometer emotweni ayiyona igajethi ewubukhazikhazi. Iwumshini owusizo ongasetshenziswa ngezindlela eziningi ezahlukene.

Uma singabheki ukufundwa kwe-tachometer, asikwazi ukucacisa ngokunembile isivinini sokujikeleza lapho i-shaft eyinhloko yenjini yemoto yethu ihamba khona. Futhi kufanelekile ukwazi ngoba ulwazi olubaluleke kakhulu. Idrayivu ngayinye inezici zayo ezinquma ukuthi iziphatha kanjani ekusetshenzisweni kwansuku zonke. Ngokuqapha isivinini senjini, ungasebenzisa izici ukufeza izinzuzo ezithile. Ngokusekelwe kwijubane lenjini, singakwazi ukusebenzisa kahle kakhulu amandla enjini lapho sishayela ngokushesha, noma singashayela ngokuzolile nangokushelela ngangokunokwenzeka, sizuze ukusetshenziswa kukaphethiloli okuphansi kakhulu ngangokunokwenzeka.

Ukuze usebenzise i-tachometer ngokunembile, umshayeli kufanele abe nolwazi mayelana nezici zenjini. Ngaphandle kolwazi olunjalo, i-tachometer izoba yinto nje engenamsebenzi yedeshibhodi. Kubalulekile ukwazi ijika le-torque, inkambo yomdwebo wayo nokuthi yiliphi isivinini inani layo eliphezulu lenzeka. Kubalulekile futhi ukwazi ukuthi amandla enjini aphezulu avela ngasiphi i-rpm, futhi i-torque namandla emidwebo ahlangana ngamuphi umdwebo wokusebenza kwenjini.

Ekushayeleni okuguquguqukayo noma kwezemidlalo, umgomo uwukugcina isivinini senjini sisezingeni elivumela ukuthi kuthuthukiswe itorque ephezulu kakhulu. Kalula nje, i-torque inesibopho sokusheshisa, hhayi amandla aphezulu. Injini isebenza kahle kakhulu ebangeni eliphakathi kwe-RPM enetorque ephezulu kanye ne-RPM enamandla amakhulu. Lapho ububanzi bebanga, injini iguquguquka kakhulu. Ekusetshenzisweni kwansuku zonke, lokhu kusho ukuthi ungakwazi ukusheshisa ngokushesha kuleli banga ngaphandle kokushintsha izilinganiso zamagiya. Ngakho-ke, kubalulekile ukwazi nokukhumbula ibanga lejubane lapho injini inomthamo omkhulu wokuthwala umthwalo. Ukwenza kube lula ukufaka amamaki ku-tachometer. Okuhle ngesikhathi sokusheshisa okusebenza kahle kakhulu ukushintsha amagiya ngezikhathi ezithi ngemva kokushintshwa, injini iqale ukusheshisa isuka ejubaneni efika ngalo noma esondela ku-torque enkulu. Khona-ke unamandla amakhulu okunqoba ukumelana nokunyakaza okubangelwa isisindo semoto, ukungqubuzana nokumelana nomoya. Ulwazi olwengeziwe olunikezwa i-tachometer yiqiniso lokuthi injini ifinyelela ubuningi bayo, i-RPM ephephile. Lokhu kuboniswa inkambu ebomvu ekugcineni kwesikali kanye nokunqunywa ohlelweni lomjovo. Ukusebenzisa injini ngaphandle kwebanga elivumelekile le-RPM kungase kubangele umonakalo kuyunithi yokushayela. Imvamisa, ukugcwala kwenjini noma induku yokuxhuma iyaphuka.

Lapho ushayela ngokonga ugcizelele ekusetshenzisweni kukaphethiloli okuphansi kakhulu, ukwazi izici zenjini nakho kuyasiza kakhulu. Yiqiniso, abashayeli abaningi banamathela esimisweni sokuthi uma i-crankshaft ijikeleza kancane, uphethiloli omncane uzodlula emagumbini omlilo, kodwa kukhona ugibe kulo mcabango. Nokho, injini akufanele yeqe ijubane elithile egiyeni ngalinye. Inhloso ukugwema izenzakalo eziyingozi ezisheshisa kakhulu ukuguga kwe-input shaft bearings kanye nezinsimbi zokuxhuma. Ukushayela kancane kakhulu kuwuhlobo lomnotho mbumbulu. Ukushayela okuphumelelayo kungahlanganiswa ngempumelelo nokusetshenziswa kancane kukaphethiloli, kodwa lokhu kudinga i-tachometer nolwazi lwezimpawu zenjini. Okufanelekile, ukwazi izici ezigcwele zangaphandle, ngegrafu yokusetshenziswa kukaphethiloli (kulula ke ukunquma isivinini esinenzuzo kakhulu). Kodwa ngisho nangesisekelo somdwebo we-torque yamandla, kungenzeka ukunquma ububanzi bezinguquko ezinhle kakhulu mayelana nokusetshenziswa kukaphethiloli. Inani lazo licishe libe yingxenye yokuguqulwa phakathi kwe-torque ephezulu namandla amakhulu. Ngokugcina injini iseduze naleli xabiso ngokufunda i-tachometer, uzoqinisekisa ukuhamba okushelelayo kanye nokusetshenziswa okuphansi kukaphethiloli.
