Centrifugal pumps are a common piece of equipment for transporting fluids across various industries. They offer advantages such as a simple structure and easy maintenance. In this article, we will explore the working principles and classifications of centrifugal pumps to help you gain a deeper understanding of them.
By utilizing the centrifugal force generated through the high-speed rotation of the impeller, mechanical energy is converted into the kinetic energy and pressure energy of the fluid, thereby achieving fluid transportation.
Types of Centrifugal Pumps
Single-stage centrifugal pump: Features only one impeller. Suitable for low-head, high-flow applications such as municipal water supply and agricultural irrigation.
Multi-stage centrifugal pump: Features two or more impellers. Suitable for high-head, low-flow applications such as water supply to high-rise buildings and boiler feed water systems.
Single-suction centrifugal pump: The impeller has only one inlet port, with liquid entering the impeller from one side, resulting in axial thrust.
Double-suction centrifugal pump: The impeller has inlet ports on both sides, with liquid entering the impeller from both sides, eliminating axial thrust and doubling the flow rate compared to single-suction pumps.
Horizontal centrifugal pump: The pump shaft is installed horizontally. Featuring a simple structure, they are easy to maintain and repair, and are widely used in industrial processes, agricultural irrigation, and similar applications.
Vertical centrifugal pump: The pump shaft is installed vertically. They have a small footprint and are suitable for space-constrained applications, such as building water supply systems and fire protection systems.
Volute Centrifugal Pump: Water exits the impeller and directly enters the spiral-shaped pump casing. Featuring a simple structure and high efficiency, it is the most widely used type.
Guide vane-type centrifugal pump: Water exits the impeller and enters guide vanes positioned externally before proceeding to the next stage or flowing into the discharge pipe. This design optimizes fluid flow conditions and is commonly employed in multistage centrifugal pumps.
Self-priming centrifugal pump: Requires no priming during startup and automatically expels air from the pump. Suitable for media containing small amounts of solid particles or gases, such as drainage and sewage treatment.
Explosion-proof centrifugal pump: Features special design and materials for safe operation in flammable and explosive environments. Suitable for hazardous locations with explosion risks, such as petroleum and natural gas facilities.
