There must is centrifugal pump in oil drilling solids control system. Centrifugal pump is a common solids control equipment. The main work of this type of pump is to bring up fluids through the transformation of the rotational energy into another energy called hydrodynamic energy. Typically, the rotational energy source is either the turbine, electric motor or engine.
The type of centrifugal pump is used as sand pump, submersible slurry pump, shear pump, and charging pump, all of which are important solids control equipments. They are defined for their different functions, but their working principle is the same.
Centrifugal pump basic components are high speed rotating impeller and fixed snail shell shaped pump casing. With several (usually are 4 ~ 12) back curved blades fastening on pump impeller axis, and with the pump shaft driven to do high speed rotation. The pump impeller is directly liquid in the work parts, are the centrifugal pump energy device. The pump casing central suction inlet and suction piping connections, suction pipe bottom with one-way bottom valve. Outlet beside pump shell connect wih outlet piping equipped with regulating valve.
Principle of operation:
The impeller of such a pump is magnetically coupled with the motor, across a separation wall which is resistant to the fluid pumped. The motor drives a rotor carrying one or several pairs of permanent magnets, and these drag around a second pair(s) of permanent magnets attached to the pump impeller.
Most centrifugal pumps are not self-priming. In other words, the pump casing must be filled with liquid before the pump is started, or the pump will not be able to function. If the pump casing becomes filled with vapors or gases, the pump impeller becomes gas-bound and incapable of pumping. To ensure that a centrifugal pump remains primed and does not become gas-bound, most centrifugal pumps are located below the level of the source from which the pump is to take its suction. The same effect can be gained by supplying liquid to the pump suction under pressure supplied by another pump placed in the suction line.
