Casting Oilfield Solids Control Centrifugal Pump Mechanical Seal

Centrifugal pump definition and general information

Oilfield Centrifugal Pump Widely Used In Drilling Fluid Solids Control. Centrifugal pump is also referred to sand pump in China. Centrifugal pump are widely used in oilfield drilling equipment and drilling mud equipment like shale shakers, desanders desilters etc.

Common centrifugal pump applications including water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pump is a fluid turbine converting potential energy of water pressure into mechanical rotational energy.

Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. 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

Technical parameters

Centrifugal pump types in solids control

Drilling fluid solids control requests many centrifugal pumps to be fit on mud tanks. According to function, we call centrifugal pumps as sand pumps, submersible slurry pumps, shear pumps, charging pumps, etc. They are defined for their different functions, but their working principle is the same

Usually in drilling fluid solids control there are horizontal centrifugal pump and vertical centrifugal pump. The difference is motor installation direction and pump feed inlet position.

To select either of installation way we need to consider the actual operation condition and general space. Presently, except installation way, there are different types pump on the seal. Mechanical sealed pump are more popular since the stable performance and reliable quality
We may face many different problem during pump operation. Please contact us for further information or support. We Aipu solids control will do come to you with optimal solutions

Application and result of centrifugal pump 

The centrifugal pump mainly used to transport drilling fluids in the solids control system. The pump can be used as charging pump for mud desander and desilter, or mixing pump for jet mud mixer. It also can be a filling pump for drilling rig mud pump.

The sand pump transports the drilling fluid containing particles at a certain pressure and flow rate to meet the feeding requirements of next equipment.

Features and benefits of centrifugal pump

¤ Semi-open impeller design, high efficiency and flow

¤ Combined seal with mechanical and packing, good perfermance and low maintenance cost

¤ Pump with high quality iron material, and impeller with high chromium alloy, long use life

¤ Stable operation and low noise

¤ Parts can be intechangeable with Mission, universal use

¤ Famous brand motor, safety and efficiency

How centrifugal pump works

Applying classical mechanics theory, assuming viscosity of the liquid equal 0 and no energy loss for the work of energy transferring from the impeller to the streamlines which means that, all separate flow will be uniforms (these approximations of physical reality to get the simpler as solid-state mechanism than a hydraulic mechanism

General explanation: Like most pumps, centrifugal pumps convert rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into the kinetic energy of the fluid. Fluid enters axially through the eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller. The doughnut-shaped diffuser, or scroll, a section of the casing decelerates the flow and further increases the pressure

In the drilling fluid solids control system, centrifugal pumps are used as a transfer pump. Mainly pump drilling fluid to desander hydro cyclone, desilter hydro cyclone. They also are combined together with mud hopper to be jet mud mixer or mud mixing pump. Pumps work as a power transition tool.
