The quality FSB Centrifugal Pump is widely used and is almost an indispensable equipment in the process system. The small size, simple operation and long service life of the centrifugal pump are the outstanding advantages of the centrifugal pump. If the pipeline delivery system is regarded as the vascular circulatory system of the human body, then the centrifugal pump is equivalent to the heart that transports blood.

The structure of quality FSB Centrifugal Pump:

The basic components of the quality FSB Centrifugal Pump are a high-speed rotating impeller and a fixed snail-shaped pump casing. Usually centrifugal pumps have several (usually 4-12) impellers with backward curved blades fastened to the pump shaft and driven by the motor for high-speed rotation with the pump shaft. The impeller is the energy supply device of the centrifugal pump, and it is the component that directly performs work on the liquid in the pump; the suction port in the center of the pump casing is connected with the suction pipeline, and the bottom of the suction pipeline is equipped with a one-way bottom valve; The outlet is connected to a discharge line equipped with a regulating valve.

The working principle of quality FSB Centrifugal Pump:
After the centrifugal pump is started, the pump shaft will drive the impeller to rotate together at a high speed, forcing the liquid prefilled between the blades to rotate. Under the action of inertial centrifugal force, the liquid moves radially from the center of the impeller to the outer circumference. The liquid medium will gain energy during the movement of the impeller, resulting in an increase in the static pressure energy and an increase in the flow rate.

When the liquid leaves the impeller and enters the pump casing, it decelerates due to the gradual expansion of the flow passage in the casing, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipeline along the tangential direction. When the liquid is thrown from the center of the impeller to the periphery, a low pressure area will be formed in the center of the impeller, and the liquid will be sucked into the center of the impeller under the action of the total potential energy difference between the liquid level of the storage tank and the center of the impeller. Relying on the continuous operation of the impeller, the liquid is continuously sucked and discharged. The mechanical energy obtained by the liquid in the quality FSB Centrifugal Pump is ultimately manifested as an increase in the static pressure energy.
