“pump”的概念、定义、习题解题方法及翻译-物理辞典

单词	pump
释义	pump A device that imparts energy to a fluid in order to move it from one place or level to another or to raise its pressure (compare vacuum pump). Centrifugal pumps and turbines have rotating impellers, which increase the velocity of the fluid, part of the energy so acquired by the fluid then being converted to pressure energy. Displacement pumps act directly on the fluid, forcing it to flow against a pressure. They include piston, plunger, gear, screw, and cam pumps. See also electromagnetic pump
