Suction Capability and Cavitation,se and vibrations excited and components damaged through cavitation erosion under certain conditions. When using the term “cavitation” the “cavitating flow”—i.e. the occurrence of local zones with two-phase flow—and “cavitation erosion” or cavitation damage must be well distinguished.作者: Suppository 時(shí)間: 2025-3-22 08:57

Pump Types and Performance Data, the kinetic energy at the impeller outlet is converted into static pressure. Different forms of impellers, diffusers, volutes and inlet casings are available to build radial, semi-axial or axial, single- or multistage, pumps mounted in horizontal or vertical position – as most suitable for the specific application.作者: 歡呼 時(shí)間: 2025-3-23 07:49 作者: Instrumental 時(shí)間: 2025-3-23 13:43
