泵是工業(yè)和民用領域中不可或缺的流體輸送設備，其性能和可靠性依賴于眾多精心設計的零部件。

例如，葉輪作為泵的核心部件，負責將機械能轉換為流體動能；而泵殼則起到保護內部組件并引導流體流動的作用。

密封件確保了泵在工作時能夠防止泄漏，維持高效運作，常見的有機械密封和填料密封兩種類型。

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.
