keskipakoispumppu

Keskipakoispumppu is the Finnish term for a centrifugal pump. It is a type of rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. The fluid enters the impeller near its axis, is accelerated by the rotation, and is then discharged at the periphery. This kinetic energy is converted into pressure energy as the fluid moves through a diffuser or volute casing.

Centrifugal pumps are widely used in various applications due to their simplicity, reliability, and cost-effectiveness. They are common in domestic water supply systems, industrial processes, irrigation, wastewater treatment, and circulation systems for heating and cooling. The design of a centrifugal pump can vary significantly depending on the intended application, including factors like the type of impeller, the casing design, and the materials used.

The operation of a centrifugal pump relies on the principle of centrifugal force. As the impeller spins, it imparts velocity to the fluid. The fluid then flows outward due to centrifugal force. The casing is designed to slow down the fluid gradually, converting its kinetic energy into potential energy (pressure). The efficiency of a centrifugal pump is influenced by factors such as the flow rate, the head (pressure) it needs to generate, and the pump's design. They are typically used for pumping liquids rather than gases.
