Oilfield  API Centrifugal pump

Oilfield API Centrifugal pump is a roto dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly  moving liquids through a piping system.

Centrifugal pumps are transporting fluids use rotational kietic energy to the hydrodynamic energy of the fluids flow. The rotational typically comes from an engine or electric motor.The centrifugal pump powered from 10HP to 1000hp. Pump size 3*2,4*3,5*4,6*5,8*6.There are different performance on pump under different voltage or frequency.

Centifuge pump process

Firstly  the centrifuge pump impeller the mud fluid enters along and near to the rotating axis .  The impeller accelerating and fluid flowing radially outward into a volute chamber .  Where it exits into the downstream piping system. Centrifugal pumps are using  large discharge through smaller heads.

Secondly  the centrifuge pump at the center of a rotating impeller and gains energy. Moving liquid to the outer diameter of the impeller.  Liquid  out of the pump by the energy ,it obtains from the rotating impeller.  Centrifugal pumps can transfer large volumes of liquid but efficiency and flow decrease rapidly as pressure and/or viscosity increases.Centrifugal pumps for solids control.An oilfield solids control system needs many centrifugal pumps to sit on or in mud tanks.

Thirdly a fluid pressure representing by lifting the fluid against gravity to a higher level. At the same time centrifuge pump transfers fluid from the mechanical rotation of the impeller to the motion and pressure of the fluid is usually described in terms of centrifugal force,.

At last cutaway view of centrifugal pump like most pumps, a centrifugal pumps converts mechanical energy from a motor to energy of a moving fluid; some of the energy goes into kinetic energy of fluid motion, and some into potential energy.especially in older sources written before the modern concept of centrifugal force. As a fictitious force in a rotating reference frame was well articulated. The concept of centrifugal force is  requiring to describe the action of the centrifugal pump.
