Kodi mphamvu za akavalo ndi chiyani ndipo zimawerengedwa bwanji?

Zamkatimu

Mphamvu za injini zoyaka zamkati zimatchedwa "mphamvu ya akavalo". Chizindikiro ichi chimakhalapo pamayendedwe onse achifumu ndi achifumu, koma sizofanana ndendende. Chochititsa chidwi kwambiri ndikuti chizindikiro cha kilowatt (kW) chimagwiritsidwa ntchito kutanthauza izi, mwachitsanzo, ku Australia.

Mphamvu yamahatchi ndi chiyani?

Mphamvu ndiyamphamvu nthawi zonse. Chizindikiro ichi chimafotokozedwa ngati mphamvu yofunikira kukweza masekeli 75 mu sekondi imodzi mpaka kutalika kwa mita imodzi. Makompyutawa adagwiritsidwa ntchito kumayambiriro kwa kusintha kwa mafakitale, pomwe akavalo adagwiritsidwabe ntchito kutola katundu m'migodi.

Imodzi mwa nthano ndizakuti mphamvu yamahatchi idapangidwa ndi wopanga James Watt. Adawonetsa momwe ma injini ake amathandizira (mahatchi angati omwe angalowe m'malo mwake).

Fomula pakuwerengera hp

Musanawerengere mphamvu yamagalimoto, muyenera kudziwa zizindikilo zingapo:

  • Makokedwe (T). Amayezedwa ndi dynamometer pa crankshaft.
  • Zosintha pamphindi (RPM). Itha kukhazikitsidwa mwina pa bolodi (kuwerenga kwa tachometer), kapena polumikiza tachometer yamagetsi (ngati galimotoyo ndi ya m'badwo wakale).

Zizindikirozi ziyenera kuyezedwa nthawi imodzi. Mwachitsanzo, kodi makokedwe pa 6000 rpm ndi chiyani. Kenako timagwiritsa ntchito njira zotsatirazi: RPM * T / 5252 (izi ndizokhazikika). Zotsatira zake zidzakhala mphamvu zenizeni za injini pa rpm ina.

M'machitidwe achifumu omwe amagwiritsidwa ntchito ku Great Britain, mphamvu yamahatchi imayesedwa m'magulu a mahatchi aku Britain (hp). Ndi mphamvu yoyezedwa ndi dynamometer yamtundu wa mabuleki pamalo ena ake monga crankshaft, shaft yotulutsa zotengera, chitsulo chogwirizira kumbuyo, kapena mawilo.

Njira yosavuta yosinthira ma kilowatts kukhala mphamvu yakuchulukitsa ndikuchulukitsa ndi 1,36. Mu tebulo ili m'munsiyi, mutha kupezanso kuchuluka kwa mphamvu ya akavalo (hp), kilowatt (kW) ndi mahatchi aku Britain (bhp).

Mafunso ndi Mayankho:

Kodi mphamvu za akavalo zimakhudza bwanji kuthamanga? Kuthamanga kwa galimoto sikukhudzidwa ndi mphamvu ya akavalo, koma ndi chizindikiro cha torque. Kutalikirana komwe kumapezeka ma torque, ndikosavuta kuti galimoto iyambe ndikuthamanga.

Chifukwa chiyani mphamvu ya injini imayezedwa mwa akavalo? Pamene anatulukira injini za nthunzi, akavalo anali njira yaikulu yoyendera. Pofuna kuti anthu aziona mmene mayunitsiwo akuyendera mosavuta, anayerekezera ndi mmene gulu la mahatchi limachitira.

Kodi mphamvu ya kavalo wa injini imayesedwa bwanji? Ngati zolembedwa zikusonyeza mphamvu mu kilowatts, ife kuchulukitsa chiwerengero ichi ndi 1.35962 - timapeza chizindikiro ndiyamphamvu. kapena ndi chilinganizo: mphamvu = torque * crankshaft revolutions / 9549 (coefficient to convert to rpm).

Kodi kavalo amakhala ndi mphamvu zochuluka bwanji? Mwachibadwa, hatchi imodzi imakhala ndi mphamvu imodzi. Koma ngati mutagwiritsa ntchito lamulo lowerengera hp. (75 kilogalamu mu sekondi imodzi amakwera ofukula ndi 1 m), ndiye kavalo mmodzi akhoza kukula kwa 13 HP kwa nthawi yochepa.
