Kodi pampu yamatope imapangidwa bwanji?

Makina amafuta amafuta opaka matope othamanga kwambiri amakhala ndi magawo awa:

(1) Kutha mphamvu

1. Chivundikiro cha mpope ndi chivundikiro cha mpope amapangidwa ndi mbale zachitsulo ndikuwotcherera pamodzi.

Mpando wonyamulira shaft woyendetsa ndi crankshaft ndikuponyera chitsulo chofunikira. Pambuyo pokonza, imasonkhanitsidwa ndikuwotchedwa ndi chipolopolo cha mpope. Pambuyo kuwotcherera, ndi annealed kuthetsa nkhawa yotsalira.

2. Shaft yoyendetsa

Miyeso ya magawo okulirapo kumapeto onse a shaft yoyendetsa pampu yamatope imakhala yofanana, ndipo ma pulleys akulu kapena ma sprocket amatha kukhazikitsidwa kumapeto kulikonse. Zothandizira mbali zonse ziwiri zimakhala ndi mzere umodzi wa radial stub roller.

3. Crankshaft

Imatengera shaft yomangidwa mowongoka kuphatikiza mawonekedwe a eccentric m'malo mwachikhalidwe chophatikizika chapampu chapampu zamasilinda atatu kunyumba ndi kunja. Imatembenuza kuponyedwa kukhala chopanga ndi chonse kukhala msonkhano, womwe ndi wosavuta kugwiritsa ntchito, wosavuta kupanga komanso wosavuta kukonza. Gudumu la eccentric, giya lalikulu la herringbone ndi shaft zimatengera kusokoneza.

(2) Kutha kwamadzi

1. Bokosi la vavu: chophatikizika chopangira chowongoka chokhala ndi chilolezo cha malita 7.3 okha. Ndi gulu la mpope wobowola wokhala ndi voliyumu yaying'ono kwambiri pakati pa mapampu amatope amphamvu kwambiri. Mabokosi atatu a valve amazindikira kutulutsa ndi kuyamwa kudzera muzochulukira zotulutsa komanso zochulukira. Mapeto amodzi a zotulutsa zotulutsa zimakhala ndi njira zinayi zothamanga kwambiri komanso thumba la mpweya lotayirira kale, ndipo mapeto enawo ali ndi valve yachitetezo chamtundu wa lever.

2. Cylinder liner: Gwiritsani ntchito bimetallic cylinder liner, zamkati zosanjikiza zamkati zimakhala ndi alloy yapamwamba ya chromium kuvala, kuuma kwamkati kumafunika kukhala mkati mwa 0.20, ndipo kuuma kwa mkati ndi ≥HRC60. Mafotokozedwe a cylinder liner ndi apakati 100-wapakati 100. ogwiritsa ntchito kuti asankhe.
