Makarantun injina suna cikin ɗaya daga cikin abubuwan da suka fi dacewa kuma masu rikitarwa na kayan aikin injiniya, waɗanda sune mahimman abubuwan haɗin nau'ikan famfo daban-daban, kettle synthesis, injin turbine, injin submersible 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 kaddarorin matsakaici, akwai high zafin jiki resistant, resistant zuwa low zafin jiki inji hatimi, inji hatimi, high matsa lamba juriya da kuma lalata juriya na granules matsakaici inji hatimi da kuma daidaita zuwa vaporize da inji hatimi na haske hydrocarbon. matsakaici, da dai sauransu, ya kamata ya kasance bisa ga daban-daban amfani don zaɓar daban-daban tsari 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.
