Menene karfin karfi kuma ta yaya ake kirga shi?

Ana kiran ƙarfin injunan konewa na ciki azaman "ikon doki". Wannan yanayin yana nan a tsarin awo da tsarin masarauta, amma ba daidai suke ba. Mafi mahimmanci sau da yawa, ana amfani da alamar kilowatt (kW) don nuna wannan ma'aunin, misali, a Ostiraliya.

Menene karfin doki?

Karfin ƙarfi yana da ƙarfi koyaushe. An bayyana wannan siga a matsayin ƙarfin da ake buƙata don ɗaga nauyin kilogram 75 a cikin dakika ɗaya zuwa tsayin mita ɗaya.

Formula don kirjin hp

Kafin kirga ikon motar, kana buƙatar ƙayyade alamomi da yawa:

• Karfin juyi (T). Ana auna shi da dynamometer a kan crankshaft.
• Juyin juya hali a minti daya (RPM). Za'a iya gyara ta ko dai a kan dashboard (karatun ƙirar mita), ko ta haɗa thometer na lantarki (idan motar ta tsohuwar tsara ce).

Dole ne a auna waɗannan alamun a lokaci guda. Misali, menene karfin juzu'i a 6000 rpm. Sannan muna amfani da tsari mai zuwa: RPM * T / 5252 (wannan kwalliya ce). Sakamakon zai zama ainihin ƙarfin injiniya a takamaiman rpm.

A tsarin mulkin mallaka da aka yi amfani da shi a Biritaniya, ana auna ƙarfin dawakai a cikin rukunin ƙarfin doki na Biritaniya (hp). Measuredarfin da aka auna ne tare da ƙarfin ƙarfin-birki mai motsi a wani takamaiman wuri kamar ƙwanƙwasawa, ƙwanƙolin fitarwa mai motsi, axle na baya, ko ƙafafu.

Hanya mafi sauƙi don juyar da kilowatts zuwa ƙarfin doki shine ninka da 1,36. A cikin teburin da ke ƙasa, zaku iya samun rabon ƙarfin dawakai (hp), kilowatts (kW) da ƙarfin dawakin Burtaniya (bhp).

Yaya ake auna ƙarfin dokin inji? Idan takardun sun nuna ikon a kilowatts, to, muna ninka wannan adadi ta 1.35962 - muna samun alamar doki. ko ta dabara: iko = juzu'i * crankshaft revolutions / 9549 (daidaitacce don canzawa zuwa rpm).

Nawa ne karfin doki? Hakika, doki ɗaya yana da ƙarfin dawaki ɗaya. Amma idan kun yi amfani da ƙa'idar don ƙididdige hp. (Kilogram 75 a cikin dakika daya yana tashi a tsaye da 1 m), sannan doki daya zai iya girma har zuwa 13 hp na ɗan gajeren lokaci.
