Drilling fluid centrifugal pump function and features

Drilling fluid centrifugal pump is a ideal corollary equipment which provide power for desander, desilter and the jet mud mixer, it also be as the replenishment pump of slurry pump. The most of components can interchange, it has the advantages of operation and maintenance is convenience, the leakage of the shaft seal is small, the
working operation is reasonable, the using lifetime is long. Because there are a lot of solid phase particles and all kinds of chemical additive in drilling fluid, so the impellers of centrifugal pump and the shell must meet the requirements of the two phases motion law, in order to decrease the wear, resistance the corrosion.

The features of drilling fluid centrifugal pump

Now the centrifugal pump is in the oilfield, usually use the water parameter design, so the performance of the pump is influenced by the solid phase particles, density and consistence of drilling fluid. The abrasive of solid phase is accelerating the abrasion and the seal of the fluid passageway, made the performance of pump is decrease, using life is short.

Drilling fluid centrifugal pump functions

The centrifugal pump is designed by the motion law of the two phases and the pressure change rules, according the best industrial and mining parameters of the experiment pump, make it fit the motion rules of the two phases in the pump. The types of the impeller is the half open, the number of the impeller is less, the radial of impeller is small, the length of the impeller is big, the inlet angle of impeller is big, the exit angle of impeller is small, the molded lines of impeller is logarithmic spiral line, in order to prove its indrawing and the abrasive resistance is good, the efficiency is higher than circular arc line blade 6% – 10%.

The volute chamber of centrifugal pump use the quasi spiral, the volute chamber section is rectangle. In order to prove it has a good waterpower and abrasive resistance. The shaft extension of centrifugal pump is short, the rigidity is good, arc is bracket, visuality is good, it has sense of beauty.

Widely Applications used of Centrifugal Pumps

Centrifugal pumps are mainly used for pumping water in industrial and residential properties. These machines move liquids with the help of kinetic energy that is stored in the motor. Although, their main function is to move water and cause the liquid to flow, centrifugal pumps are also used in sewage, food processing plants, water treatment plants, manufacturing plants, chemical and petroleum industries and have become extremely popular down the years.

What are the components of a rig’s mud system?

Here are descriptions of some of the equipment used to circulate and monitor drilling fluid or mud:

Mud pump: A large, high-pressure reciprocating pump used to circulate the mud on a drilling rig.

Mud tanks (or mud pits): A mud tank is an open steel tank used for holding drilling fluids. Some mud tanks are used for suction to the mud pumps, settling of mud sediments and storage of reserve mud. Drilling mud is circulated through a series of open tanks to remove sand and fine sediments.

Kicker hose: A high-pressure rubber hose that connects the mud pump discharge line to the mud line.

Mud line: A high-pressure steel line that mud flows through from the kicker hose to the stand pipe (the stand pipe goes up the side of the derrick).

Shale shaker: A vibrating screen unit that is used to separate cuttings from the circulating fluid coming out of the wellbore. The separated cuttings vibrate over the end of the shakers to a shale bin, and the drilling mud falls back into the mud tanks.

Hopper: A large funnel mounted in the mud tank circulating system into which dry chemicals can be poured to mix uniformly with the drilling mud.

Submersible pumps supply from DC Machinery

Until recently, drilling rig operators typically used cast-iron waste-water submersible pumps to move the spent drilling mud in and out of the reserve pits, but these pumps experienced high failure rates. Because of the weight and high solids content of the mud, the pumps often ran dry or against closed discharges. Some failure modes included:

Broken shafts and impeller bolts
Loosened impeller keyways
Failed seals

The key components of these pumps—including the impeller, wear plate and agitator—are made of high-chrome iron to withstand abrasion, and the bearings are tough and oversized. These pumps perform better and last far longer than their standard wastewater predecessors in the harsh oilfield environment.
