Iphampu kawoyela iyithuluzi elivamile elisetshenziswa ukuthutha uketshezi (imvamisa uphethiloli owuketshezi noma uwoyela wokugcoba) ukusuka endaweni eyodwa ukuya kwenye.Inezinhlobonhlobo zezicelo emikhakheni eminingi, okuhlanganisa imboni yezimoto, i-aerospace, imboni yokwakha imikhumbi kanye nokukhiqizwa kwezimboni, njll.
Isimiso sokusebenza sephampu kawoyela singachazwa kalula ngokuthi: uketshezi olunyakazayo lusuka endaweni enomfutho ophansi luye endaweni enengcindezi ephezulu ngokucindezela okukhiqizwa ukunyakaza kwemishini.Okulandelayo kuzokwethula ngokuningiliziwe izimiso zokusebenza zamaphampu kawoyela amabili avamile.
1. Umgomo wokusebenza wephampu yegiya:
Iphampu yegiya iyiphampu evamile yokugudluza evumayo ehlanganisa amagiya amabili ahlanganayo.Igiya elilodwa libizwa ngegiya lokushayela kanti elinye libizwa nge-drin gear.Uma igiya lokushayela lizungeza, igiya elishayelayo nalo liyazungeza.Uketshezi lungena egunjini lokumpompa ngegebe phakathi kwamagiya bese luphushelwa lapho amagiya ezungeza.Ngenxa ye-meshing yamagiya, uketshezi lucindezelwa kancane kancane egunjini lepompo futhi luphushelwe endaweni enengcindezi ephezulu.

2. Isimiso sokusebenza sephampu yepiston
Iphampu ye-piston iyiphampu esebenzisa ipiston ukuze iphindiselele egumbini lepompo ukuze iphushe uketshezi.Iqukethe i-pistons eyodwa noma ngaphezulu, amasilinda nama-valve.Lapho i-piston iqhubekela phambili, ukucindezela ekamelweni lepompo kuyehla futhi uketshezi lungena ekamelweni lepompo nge-valve yokungena emoyeni.Njengoba i-piston ihlehla, i-valve yokungena iyavaleka, umfutho uyanda, futhi uketshezi luphushwa lubheke lapho kuphuma khona.I-valve yokuphuma ibe isivuleka futhi uketshezi ludedelwa endaweni yokucindezela okukhulu.Ukuphinda le nqubo, uketshezi luzothuthwa ngokuqhubekayo ukusuka endaweni yokucindezela okuphansi kuya endaweni yokucindezela okukhulu.
Izimiso zokusebenza zalawa maphampu kawoyela amabili asekelwe emehlukweni wengcindezi yoketshezi ukuze kuzuzwe ukuthuthwa koketshezi.Ngokuhamba kwemishini yemishini, uketshezi luyacindezelwa noma luphushwe, ngaleyo ndlela lwenze ukucindezela okuthile, okuvumela uketshezi ukuba lugeleze.Amaphampu kawoyela ngokuvamile ahlanganisa umzimba wephampu, igumbi lepompo, idivayisi yokushayela, ama-valve nezinye izakhi zokubona ukuthuthwa nokulawula uketshezi.
