泵是工业和民用领域中不可或缺的流体输送设备，其性能和可靠性依赖于众多精心设计的零部件。
例如，叶轮作为泵的焦点部件，卖力将机械能转换为流体动能 ；而泵壳则起到� ；つ诓孔榧⒁剂魈辶鞫淖饔�。
密封件确保了泵在事情时能够避免泄漏，维持高效运作，常见的有机械密封和填料密封两种类型。
Pumps are indispensable fluid transfer devices in both industrial and civilian fields, with their performance and reliability depending on a multitude of meticulously designed components.
For instance, the impeller, as the core component of a pump, is responsible for converting mechanical energy into fluid kinetic energy;
while the pump casing protects internal components and guides fluid flow. Seals ensure that the pump can prevent leaks during operation,
maintaining efficient operation, with common types being mechanical seals and packing seals.
