keskupakoispumpun

Keskipakoispumpun is a Finnish term referring to a centrifugal pump. A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. The fluid enters the impeller near the axis of rotation and is thrown outward by centrifugal force as the impeller rotates. This outward motion causes the fluid to accelerate and gain kinetic energy. The fluid then enters a volute casing, which is a progressively expanding spiral-shaped chamber that surrounds the impeller. The volute converts the kinetic energy of the fluid into pressure energy.

Centrifugal pumps are widely used in many applications due to their simple design, reliability, and ability to handle a wide range of flow rates and pressures. They are commonly found in water supply systems, sewage treatment plants, industrial processes, and HVAC systems. The performance of a centrifugal pump is typically described by a pump curve, which plots flow rate against head (pressure) and efficiency. Key components of a centrifugal pump include the impeller, casing (volute), shaft, seals, and bearings. The selection of a centrifugal pump depends on factors such as the required flow rate, head, fluid properties, and operating conditions.
