He aha ka horsepower a pehea e helu ai?

ʻO ka mana o nā ʻenekini kuni kūloko i kapa ʻia ʻo "horsepower". Aia kēia pae ma nā metric a me nā ʻōnaehana imperial, akā ʻaʻole like like. ʻO ka mea ʻoi aku ka liʻiliʻi o ka manawa, hoʻohana ʻia ke kilowatt (kW) e hōʻailona i kēia parameter, no ka laʻana, ma Australia.

He aha ka horsepower?

ʻO ka horsepower he horsepower mau. Hoʻomaopopo ʻia kēia palena e like me ka ikaika e pono ai e hāpai i kahi nui o 75 mau kilogram i hoʻokahi kekona i ke kiʻekiʻe o hoʻokahi mika. Ua hoʻohana ʻia kēia ʻōnaehana kamepiula i ka wanaʻao o ke kipi hana, ke hoʻohana mau ʻia nā lio e lawe i nā waiwai mai nā mines.

ʻO kekahi o nā kaʻao ka mea horsepower anakahi e hoʻomohala ʻia e James Watt. Ua hōʻike ʻo ia i ka maikaʻi o kāna ʻenekini mahu (ehia mau lio e hiki ke hoʻololi i kahi anakahi).

Kumumanaʻo no ka helu ʻana hp

Ma mua o ka helu ʻana i ka mana o ka kaʻa, pono ʻoe e hoʻoholo i kekahi mau anakuhi:

• Pūnaewele (T). Ana ʻia ia me ka dynamometer ma ka crankshaft.
• Nā Hoʻololi i kēlā me kēia minuke (RPM). Hiki ke hoʻopaʻa ʻia ma ka dashboard (heluhelu heluhelu tachometer), a i ʻole ma ka hoʻopili ʻana i kahi tachometer uila (inā ʻo ke kaʻa o ka hanauna kahiko).

Pono e ana ʻia kēia mau anakuhi i ka manawa like. ʻO kahi laʻana, he aha ka ikehu ma 6000 rpm. A laila hoʻohana mākou i kēia ʻano: RPM * T / 5252 (he mea paʻa kēia). ʻO ka hopena ka mana o ka ʻenekini maoli ma kekahi rpm.

I ka ʻōnaehana imperial i hoʻohana ʻia ma Great Britain, ana ʻia ka horsepower i nā anakahi o ka horsepower Pelekania (hp). ʻO kēia ka mana i ana ʻia me ka dynamometer type-brek i kahi kikoʻī, e like me ka crankshaft, ka puka hoʻopuka hoʻoili, axle hope, a i ʻole nā ​​huila.

ʻO ke ala maʻalahi loa e hoʻololi i nā kilowatts i ka horsepower ʻo ka hoʻonui ʻana i ka 1,36. Ma ka papa ma lalo, hiki iā ʻoe ke ʻike i ka ratio o ka horsepower (hp), kilowatts (kW) a me ka horsepower Pelekane (bhp).

Mokuna:	OHS	kw	hp
OHS	1	0,745700	101,387
kw	134,102	1	135,962
hp	0,986320	0,735499	1

Nā nīnau a me nā pane:

Pehea ka hopena o ka horsepower i ka wikiwiki? ʻAʻole pili ka wikiwiki o ke kaʻa e ka horsepower, akā ma ka hōʻailona torque. ʻOi aku ka nui o ka laulā e loaʻa ai ka torque, ʻoi aku ka maʻalahi o ke kaʻa e hoʻomaka a piʻi i ka wikiwiki.

No ke aha i ana ʻia ai ka mana ʻenekini ma ka horsepower? I ka hana ʻia ʻana o nā ʻenekini mahu, ʻo ka lio ke ala nui o ka lawe ʻana. I mea e maʻalahi ai ka loiloi ʻana o ka poʻe i ka hana o nā ʻāpana, ua hoʻohālikelike ʻia lākou me ka hana a kahi hui lio.

Pehea e ana ʻia ai ka ikaika o ka ʻenekini? Inā hōʻike ka palapala i ka mana i nā kilowatts, a laila hoʻonui mākou i kēia helu me 1.35962 - loaʻa iā mākou ka hōʻailona horsepower. a i ʻole ma ke ʻano: power \u9549d torque * crankshaft revolutions / XNUMX (kumu e hoʻololi i rpm).

Ehia ka nui o ka ikaika o ka lio? ʻO ka mea maʻamau, hoʻokahi lio ka ikaika. Akā inā pili mākou i ke kānāwai no ka helu ʻana i ka hp. (75 kilokani piʻi kū pololei ma ka 1 m i hoʻokahi kekona), a laila hiki i hoʻokahi lio ke ulu i 13 hp no ka manawa pōkole.
