The maintenance drilling mud centrifugal pump in oilfield

Centrifugal pump is used for transferring drilling mud. It can be used as feeding pump for desander, desilter or used as mixing pump for jet mud mixer. Also it can be used as trip pump, and supercharging pump for rig mud pump. But how to do if centrifugal pump breaks down in the process of mud solids control? Now we introduce some processing methods for centrifugal pump breakdown resulting from various reasons.
1. pump can not start or load too big
(1) prime mover or power is not normal. The processing method is check the power and prime mover.
(2) pump stuck. The processing method is using hand shaft coupling to check, if necessary, eliminate static and dynamic parts faults.
(3) packing gland too tight. The processing method is relaxing packing.
(4) discharge valve has not been closed. The processing method is closing discharge valve, restart.

(5) balance pipe is not unobstructed. The processing method is dredge balance pipe.
2. pump not drainage
(1) insufficient irrigation pump (or inner pump gas is not throughly exhausted). The processing method is to infuse pump.
(2) Wrong pump rotating direction. Method is to check rotating direction.
(3) Pump rotating speed is too slow. Method is check rotate speed, faster it.
(4) mesh plugging, bottom valve is ineffective. The processing method is check mesh, eliminate sundry.
(5) smoke height is too high, or suction liquid tank occurs vacuum. The processing method is to reduce suction height, Check absorb liquid tank pressure.
3. pump breaks after drainage
(1) inhaled pipeline leaks. The processing method is to check inhaled side pipe joints and packing box sealing.
(2) When filling pump, suction side gas is not over. The processing method is asked to infuse pump.
(3) inhaled side was suddenly blocked by foreign bodies. The processing method is stop the pump to handle foreign bodies.
(4) inhale amount of gas. The processing method is checking the suction whether has vortex, submerged depth whether is too shallow.

Drilling centrifugal pump used as the oilfield sand pump

Centrifugal pump is a sub-class of dynamic axisymmetric work-absorbing turbo machinery. Centrifugal pump are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. 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 (Hydraulic head) or by lifting the fluid, against gravity, to a higher altitude. The transfer of energy from the mechanical rotation of the impeller to the motion and pressure of the fluid is usually described in terms of centrifugal force, 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 not actually required to describe the action of the centrifugal pump.

Drilling centrifugal pump can be designed from 3x2 to 8x6. Selecting Drilling Centrifugal Pump is according to flow rate demand. Furthermore, the flow rate is related with motor power, head, electric system, the impeller size. Drilling Centrifugal Pump in drilling mud process system is mainly power supply.

Drilling mud centrifugal pump principle
Centrifugal pump is combined with impeller and casing. Drilling fluid will be sucked from impeller side, when impeller rotates at high speed there will be centrifugal force and gain power or pressure. Then fluid flow through impeller path will produce pressure out. The drilling mud will come out under certain pressure.
If centrifugal pump is feeding pump for hydrocyclone separator the drilling mud will flow into cones under pressure and get a screw to separate larger particles out. If the pump is only transferring pump or for mixing system the pressure will ensure the sufficient motility and flow rate

Centrifugal Pumps As Drilling Fluid Mud Pumps for Customers in Mexico

From the use of centrifugal pumps can be divided into civil and industrial pumps, from the transmission medium can be divided into clear water pump, trash pump, corrosion resistant pumps and so on.
Because of pump startup, the pump outlet pipeline not water, so there is not resistance line resistance and the lifting height, the pump is started, the pump head is low, flows, time pump motor (shaft power) Output great (according to the pump performance curve), it is easy to overload, it will cause damage to the pump motor and wiring, so start to close the valve to the pump running.
Basic Centrifugal Pumping Concepts
To better illustrate the essential principles of centrifugal pumping, it may be useful to consider a simplified version of an industrial pumping mechanism. A cylindrical can with a pair of rotary vanes along its interior can be attached to a shaft. This shaft has a pulley unit responsible for agitating the can with rotational movements. Once the can is filled with water, the pulley begins to rotate the shaft at high speed, causing the can to spin. As the water in the can rotates, centrifugal force pushes it out toward the walls of the can where it is pressed against the edges of its container.

Drilling fluid centrifugal pump is a ideal equipment transferring drilling mud

Centrifugal pump is used for transferring drilling mud. It can be used as feeding pump for desander, desilter, or used as mixing pump for Jet Mud Mixer. Also it can be used as trip pump,and supercharging pump for rig mud pump. All KOSUN centrifugal pumps use tungsten carbide mechanical seal, with famous brand Bearing. And spare parts interchangeable with most of the international Brand pump which helps customer to source spare parts easily. Open impeller design that lowers axial thrust loads, and make it easier for installation, repair and maintenance.

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 working environment of the centrifugal pump is very bad, the pump transport a large number of fluid with sand, so the seal of shaft end is very well, it is very difficult to solve it by the common pump seal method. At the same time, because the medium has the abrasiveness and corrosive, so the inner pump is often destroyed, so need to plugging the n before and after impellers between the plates. Otherwise, the matching of flow and the head of the centrifugal pump with the hrdrocyclone( desilter, desander, jet mud mixer device) must be appropriate. If not, the hydrocyclone can’t normal work.

If centrifugal pump is feeding pump for hydrocyclone separator the drilling mud will flow into cones under pressure and get a screw to separate larger particles out. If the pump is only transferring pump or for mixing system the pressure will ensure the sufficient motivity and flow rate.

KOSUN has been providing the drilling fluid solids control equipment and solids control system for more than 20 years,main solids control equipments including the shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, submersible slurry pump, shear pump,mud agitator, mud gun, drilling fluid mud cleaner, decanter centrifuge, jet mud mixer, mud tank, diesel tank, water tank, etc.
