Drilling Fluid Centrifugal Pump in Solid Control

DRILLING FLUID CENTRIFUGAL PUMP IN SOLID CONTROL
LET US TALK ABOUT THE DRILLING FLUID CENTRIFUGAL PUMP
Drilling fluid centrifugal pump is a sub-class of dynamic axisymmetric work-absorbing turbomachinery. [1 Centrifugal pumps are used to transport liquids/fluids by the conversion of the rotational kinetic energy to the hydro dynamics energy of the liquid flow. The rotational energy typically comes from an engine or electric motor or turbine. In the typical simple case, the fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits.
THE APPLICATION OF DRILLING FLUID CENTRIFUGAL PUMP
Common uses include water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.
PRISINPLE OF OPERATION ABOUT DRILLING FLUID CENTRIFUGAL PUMP
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 magnet]]s and these drag around a second pair(s) of permanent magnets attached to the pump impeller.

DRILLING FLUID CENTRIFUGAL PUMP, HOW IT WORK?

Like most pumps, a centrifugal pump converts mechanical energy from a motor to energy of a moving fluid. A portion of the energy goes into kinetic energy of the fluid motion, and some into potential energy, represented by fluid pressure or by lifting the fluid, against gravity, to a higher altitude.

SOME TYPES OF DRILLING FLUID CENTRIFUGAL PUMP

Vertical centrifugal pumps

Vertical centrifugal pumps are also referred to as cantilever pumps. They utilize a unique shaft and bearing support configuration that allows the volute to hang in the sump while the bearings are outside of the sump.    A common application for this style of pump is in a [[parts washer]].



Froth pumps

In the mineral processing industry, or in the extraction of oilsand, froth is generated to separate the rich minerals or bitumen from the sand and clays. Froth contains air that tends to block conventional pumps and cause loss of prime. Over history, industry has developed different ways to deal with this problem. One approach consists of using vertical pumps with a tank. Another approach is to build special pumps with an impeller capable of breaking the air bubbles. In the pulp and paper industry holes are drilled in the impeller. Some pumps may feature a large eye, an inducer or recirculation of pressurized froth from the pump discharge back to the suction to break the bubbles.
Multistage centrifugal pump

A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts.


ABOUT THE PRIMING OF DRILLING FLUID CENTRIFUGAL PUMP
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.  

SOME PROBLEMS OF DRILLING FLUID CENTRIFUGAL PUMP

1. Wear of the Impeller—can be worsened by suspended solids

2. Corrosion inside the pump caused by the fluid properties

3. Overheating due to low flow

4. Leakage along rotating shaft

5. Lack of prime—centrifugal pumps must be filled (with the fluid to be pumped) in order to operate

DRILLING FLUID CENTRIFUGAL PUMP IN SOLID CONTROL

An oilfield solids control system needs many centrifugal pumps to sit on or in mud tanks. The types of centrifugal pumps used are sand pumps, submersible slurry pumps, shear pumps, and charging pumps. They are defined for their different functions, but their working principle is the same.
