Fundamental Concepts of Pumps and Centrifugal Fans

Fundamental Concepts of Pumps and Centrifugal FansBased on their specific operating methods and overall structural design, both pumps and centrifugal fans can be categorized into several types: impeller-type (centrifugal) and positive displacement. Impeller pumps and fans are widely utilized. Pumps and centrifugal fans employed in thermal power plants and industrial/civil boiler rooms are predominantly impeller pumps and centrifugal fans. Therefore, this book focuses on energy-saving technologies for pumps and centrifugal fans. The discussion centers on the performance characteristics of impellers and fans. Impeller pumps and centrifugal fans include centrifugal fans and axial-flow fans. Due to space limitations, the following sections provide a brief overview of pumps, centrifugal fans, piping systems, and key concepts related to energy conservation.
