Tare da haɓakar ƙaƙƙarfan bangon ciki na bututun ƙarfe, ƙarfin ramin da ke cikin bututun ya ragu, musamman ma a wurin fitar da bututun, galibi saboda ramin ramin da ke cikin bututun yana hawa ƙasa, ramin ramin. abin ya shafa da roughness na bango, kuma cavitation ya karye kuma ya rushe.

Tare da haɓakar ƙaƙƙarfan bangon ciki na bututun ƙarfe, ƙarfin kuzarin motsa jiki mai rikicewa a cikin bututun yana ƙaruwa, musamman a yankin ƙofar bututun, kuzarin motsa jiki shine mafi girma, galibi saboda kaifi chamfer a ƙofar bututun. bututun ƙarfe yana haɓaka ƙarfin tashin hankali a ƙofar bututun ƙarfe.

A ƙarƙashin yanayin ƙarancin alluran matsa lamba (30MPa), haɓaka ƙaƙƙarfan bangon ciki na bututun ƙarfe yana da ɗan tasiri akan yawan kwararar taro da matsakaicin saurin bugun bututun ƙarfe. Duk da haka, a karkashin yanayin high allura matsa lamba (180MPa), tare da karuwa da roughness, da taro kwarara kudi na bututun ƙarfe kanti yana ƙaruwa kadan, da matsakaita gudun kanti a hankali ragewa, yafi saboda roughness na ciki bango na ciki. bututun ƙarfe yana ƙara hasara yayin aiwatar da kwarara. Ƙarƙashin yanayin matsa lamba na jet, ƙarfin daɗaɗɗen ƙarfi a mashigin bututun ƙarfe yana ƙaruwa da sauri tare da haɓakar ƙazanta, yayin da ƙarfin tashin hankali a cikin kanti yana ƙaruwa kaɗan a ƙarƙashin ƙananan matsa lamba.

Ƙarfin tashin hankali a bakin bututun bututun yana tare da axis X daga kasan bututun zuwa bango na sama na bututun yana nuna yanayin fara ƙarami sannan kuma yana ƙaruwa, ƙarfin tashin hankali a tsakiyar yankin bututun shine mafi ƙanƙanta, da kuma tashin hankali tsanani a cikin babba bango cavitation Layer yanki na bututun ƙarfe ne babba, da kuma fragmentation na cavitation kara habaka m tashin hankali a cikin bango yankin sama da nozzle outlet, wanda hakan ke haɓaka ƙarfin tashin hankali.
