Chidziwitso cha fan of bulldozer Fani ya bulldozer ndiye gawo lalikulu la makina ozizira a bulldozer, omwe amagwiritsidwa ntchito kwambiri kutulutsa kutentha kuchokera kuzinthu zazikulu monga injini ndi ma hydraulic system pokakamiza kutuluka kwa mpweya, kuwonetsetsa kuti zidazo zimasunga kutentha kwanthawi zonse pakalemedwe kwambiri. Kapangidwe kake kamayenera kugwirizana ndi mphamvu yamagetsi, malo ogwirira ntchito, ndi zofunikira zowononga kutentha kwa ma bulldozers, ndipo nthawi zambiri zimakhala ndi makhalidwe monga kuchuluka kwa mpweya, kukana kuvala, ndi kugwedezeka kwamphamvu. (monga mbale zachitsulo) kapena mapulasitiki aumisiri, ndipo mawonekedwe a tsamba amakongoletsedwa ndi aerodynamics kuti apititse patsogolo kutentha kwa kutentha; Njira zoyendetsera galimoto zimagawidwa m'mitundu iwiri: makina oyendetsa (oyendetsedwa ndi crankshaft ya injini kudzera pa lamba) ndi hydraulic drive (yoyendetsedwa ndi pampu ya hydraulic, yomwe imatha kusintha liwiro). Zotsirizirazi ndizofala kwambiri m'mabulldozer akuluakulu amakono ndipo zimatha kusintha mwachangu liwiro la fan malinga ndi momwe kutentha kumafunikira kuti muchepetse kugwiritsa ntchito mphamvu.
Kugwiritsa ntchito fani ya bulldozer
Ma bulldozers, monga zida zoyambira pakumanga uinjiniya, amagwiritsidwa ntchito kwambiri mumigodi, zomangamanga, kukonzanso minda ndi zochitika zina. Kugwiritsa ntchito kwa mafani awo kumakhudza mwachindunji kudalirika komanso magwiridwe antchito a zida, zomwe zikuwonetsedwa m'magawo awa:
Kuziziritsa kwa injini
Injini ya bulldozer imapanga kutentha kwakukulu panthawi yotulutsa mphamvu zambiri. Kukupiza kumayamwa mpweya wozizira, kumayenda kudzera mu radiator ya injini, ndikutaya kutentha mu choziziritsa kumlengalenga, kupeŵa kutayika kwa mphamvu ndi kuwonongeka kwa zigawo (monga kupindika kwa pistoni, kusweka kwa silinda, ndi zina zotero) chifukwa cha kutentha kwa injini. Kumalo otentha kwambiri-(monga ntchito yapanja m'chilimwe) kapena pamene mukulemedwa kwambiri (monga kukwera ndi kukwera), kuzizira kwa mafani Agwirizane ndi zovuta zogwirira ntchito.
Ma bulldozers nthawi zambiri amagwira ntchito m'malo afumbi, amatope, okwera kapena otsika kwambiri, ndipo mawonekedwe amafanizi amayenera kukhala ndi zotsutsana ndi kuipitsidwa ndi nyengo. Mwachitsanzo, pamwamba pa ma fan blades amatha kuthandizidwa ndi -njira zoletsa dzimbiri kuteteza kukokoloka kwa matope ndi madzi; Chipangizo choyendetsa galimoto chiyenera kutsekedwa bwino kuti fumbi lisalowe ndi kusokoneza moyo wake. Kuphatikiza apo, mafani ena amatha kusintha liwiro lawo pogwiritsa ntchito njira yowongolera mwanzeru (monga kusintha molingana ndi kutentha kwa madzi a injini), kuchepetsa kugwiritsa ntchito mphamvu ndi phokoso ndikuwonetsetsa kuti kutentha kumatayika.

Bulldozer fan ndiye "chizindikiro chozizira" chomwe chimasunga magwiridwe antchito amagetsi amagetsi ndi ma hydraulic system, ndipo magwiridwe ake amakhudza mwachindunji magwiridwe antchito, kudalirika, komanso moyo wantchito wa bulldozer. Popanga makina omanga anzeru ndi mphamvu-zopulumutsa, mafani a bulldozer akuwongoleredwa kuti azitha kusintha liwiro, kugwiritsa ntchito mphamvu pang'ono, komanso kutha kusinthasintha kuti akwaniritse zosowa za kutha kwa kutentha m'malo osiyanasiyana ogwirira ntchito.
