  济南作为山东的重要城市,工业发展迅速,其中离心风机是通过将旋转动能转化为流体流动的风动力能来输送流体的装置。旋转能量通常来自于电动机或汽轮机。离心机在工业上的应用比任何其他类型的风机都要多。

  As an important city in Shandong, Jinan has developed rapidly in industryCentrifugal pumps are devices that are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an electric motor or steam turbine (in case of turbine-driven feedwater pumps). Centrifugal pumps are used in more industrial applications than any other kind of pump. The most common centrifugal pump is the volute pump.

  离心风机通过叶轮的眼(低压区)在高速旋转。当叶轮和叶片转动时,它们会将动量传递给进料流体。流体加速地从泵的追逐和真空中向外加速。

  产生于叶轮的眼睛,不断地吸引更多的液体进入泵。当流体的速度增加时动能增加。高动能流体从叶轮区域强制进入蜗壳。在体积中,流体通过一个不断增加的交叉流动。

  In the volute of the pump fluid enters the pump axially through the eye of the impeller (low pressure area) which rotates at high speed. As the impeller and blades rotate, they transfer momentum to incoming fluid. The fluid accelerates radially outward from the pump chasing and a vacuum is created at the impellers eye that continuously draws more fluid into the pump. As the fluid’s velocity increases its kinetic energy increases. Fluid of high kinetic energy is forced out of the impeller area and enters the volute. In the volute the fluid flows through a continuously increasing cross-sectional area, where the kinetic energy is converted into fluid pressure (according the Bernoulli’s principle).

  每台离心机由数百个部件组成。有几个部件是虚拟离心泵的共同点。这些组分可细分为湿部和机械部。泵的湿部包括那些决定泵的水力性能的部件。两个主要的湿端是叶轮和机壳。在某些情况下,直接轴承可以水润滑。机械端包括在壳体内支撑叶轮的部件。泵的机械端部包括泵轴、密封、轴承和轴套,结构非常严谨。

  Centrifugal Pump-minEach centrifugal pump is made of hundreds of parts. There are a few components that virtually every centrifugal pump has in common. These components can be subdivided into the wet end and the mechanical end.

  The wet end of the pump includes those parts that determine the hydraulic performance of pump. The two primary wet ends are the impeller and casing. In some cases the first radial bearing can be water lubricated. In this case also bearing can belongs to wet ends.
