Makarantu na injina suna cikin ɗayan mafi haɓakawa da rikitarwa na kayan aikin injiniya, waɗanda sune mahimman abubuwan nau'ikan famfo daban-daban, tulun kira na amsawa, injin injin turbine, injin da ke ƙarƙashin ruwa da sauransu.Ayyukan rufewarsa da rayuwar sabis sun dogara da abubuwa da yawa, kamar zaɓi, daidaitaccen na'ura, shigarwa daidai da amfani.
1. Hanyar zaɓi.
Mechanical hatimi bisa ga yanayin aiki da kuma kaddarorin matsakaici, akwai high zafin jiki resistant, resistant zuwa low zazzabi inji hatimi, inji hatimi, high matsa lamba juriya da lalata juriya na granules matsakaici inji hatimi da kuma daidaita zuwa vaporize inji hatimi na haske hydrocarbon. matsakaici, da sauransu, ya kamata ya kasance daidai da amfani da daban-daban don zaɓar tsarin daban-daban da kayan hatimin inji.
Zaɓin manyan sigogi sune: matsa lamba na hatimi (MPa), zafin jiki na ruwa (℃), saurin aiki (m / s), halayen ruwa da shigar da sarari mai inganci, da sauransu.
Ka'idodin zaɓi na asali sune:
1. Dangane da matsa lamba na ɗakin rufewa, tsarin rufewa ya ƙaddara don ɗaukar nau'in ma'auni ko rashin daidaituwa, fuska ɗaya ko fuska biyu, da dai sauransu.
2. Dangane da saurin aiki, nau'in jujjuya ko a tsaye, matsa lamba na hydrodynamic ko nau'in nau'in lamba an ƙaddara.
3. Bisa ga yawan zafin jiki da ruwa Properties, ƙayyade gogayya nau'i-nau'i da karin sealing kayan, da kuma daidai zaži inji hatimi wurare dabam dabam kariya tsarin kamar lubrication, wanka, zafi adana da sanyaya, da dai sauransu.
4. Dangane da tasiri mai tasiri na hatimin shigarwa, an tabbatar da cewa an karbi Multi-spring ko daya bazara ko raƙuman ruwa, kuma ana ɗaukar nauyin ciki ko na waje.
