什么叫汽蝕余量？什么叫吸程？各自計(jì)量單位表示字母？
泵在工作時(shí)液體在葉輪的進(jìn)口處因一定真空壓力下會(huì)產(chǎn)生汽體，汽化的氣泡在液體質(zhì)點(diǎn)的撞擊運(yùn)動(dòng)下，對(duì)葉輪等金屬表面產(chǎn)生剝蝕，從而破壞葉輪等金屬，此時(shí)真空壓力叫汽化壓力，汽蝕余量是指在泵吸入口處單位重量液體所具有的超過(guò)汽化壓力的富余能量。l單位用米標(biāo)注，用（npsh）r。吸程即為必需汽蝕余量δh：即泵允許吸液體的真空度，亦即泵允許的安裝高度，單位用米。
吸程=標(biāo)準(zhǔn)大氣壓（10.33米）-汽蝕余量-安全量（0.5米） D12-25*5 DG12-25*5 DY12-25*5 DF12-25*5
