Hydraulic Balancing Devicese the sum of the individual impeller thrusts. The thrust magnitude (in pounds) will be approximately equal to the product of the net pump pressure (in pounds per square inch) and the annular unbalanced area (in square inches). Actually the axial thrust turns out to be about 70 to 80 percent of this theoretical value (see Chap. 5).作者: 古董 時(shí)間: 2025-3-23 03:02 作者: 有權(quán) 時(shí)間: 2025-3-23 06:39

Classification and NomenclaturePumping can be defined as the addition of energy to a fluid to move it from one point to another. It is not, as frequently thought, the addition of pressure. Because energy is capacity to do work, adding it to a fluid causes the fluid to do work, normally flowing through a pipe or rising to a higher level.作者: Incorruptible 時(shí)間: 2025-3-28 13:09
