陶瓷渣漿泵的汽蝕余量NPSH
NPSH是汽蝕余量的一種，是指泵入口處液體所具有的總水頭與液體汽化時的壓力頭之差，單位用米（水柱）標注，用（NPSH）表示。
陶瓷渣漿泵的汽蝕余量NPSH主要目的是渣漿泵運行過程中不發生汽蝕，根據不同狀況渣漿泵汽蝕余量可分為三種：NPSHr——泵汽蝕余量，又叫必需的汽蝕余量或泵進口動壓降，越小抗汽蝕性能越好； NPSHc——臨界汽蝕余量，是指對應泵性能下降一定值的汽蝕余量； [NPSH]——許用汽蝕余量，是確定泵使用條件用的汽蝕余量，通常取 [NPSH]=（1.1～1.5）NPSHc。
NPSH of Ceramic Slurry Pump
NPSH is a type of cavitation margin, which refers to the difference between the total head of liquid at the pump inlet and the pressure head at the time of liquid vaporization, expressed in meters (water column) and (NPSH).
The main purpose of the NPSH of the ceramic slurry pump is to prevent cavitation during the operation of the slurry pump. According to different conditions, the NPSH of the slurry pump can be divided into three types: NPSHr - Pump NPSH, also known as the necessary NPSH or pump inlet dynamic pressure drop, the smaller the NPSH, the better the anti cavitation performance; NPSHc - Critical NPSH, refers to the NPSH that corresponds to a certain decrease in pump performance; [NPSH] - Permissible NPSH, which is the NPSH used to determine the operating conditions of a pump, usually taken as [NPSH]=(1.1-1.5) NPSHc.
