Mechanical Seal Solids Control Centrifugal Pump For Fluids Transmit Energy

Centrifugal Pumps Used To Transmit Energy To Fluids Through The Work Of A Field Of Centrifugal Forces.

Specification of APSB series solids control centrifugal pump

Application of solids control centrifugal pump 

Drilling mud solids control Centrifugal pumps used in well drilling fluids system are mechanical seal pump. Aipu produce high quality centrifugal pumps. Centrifugal pump is also called sand pump, as the dilling fluid to be processed contain large quantity drilled solid or cuttings.

Trip Pump: Trip pump will sit at trip tank to transfer mud from trip tank into drill hole directly in special conditions. The pump normal driven by 11 or 15kw electrical motor with a 4×3 size pump. The mud flow 200 to 250GPM is enough.

Desander & desilter feeding pump: It is normally 8×6 size pump driven by 55kw motor for 1000GPM mud flow for oil and gas drilling, but 6×5 or 5×4 size pump with smaller electrical motor will be used for smaller mud flow capacity for oil & gas drilling, coal bed methan drilling, horizontal directional drilling or water well drilling.

Water pump: The water pump will set on water tank with water line supply to solids control mud tank. A diesel pump may work as standby incase of fire.

Mixing Pump: The mixing pump normally 8×6 size driven by 55kw electrical motor to supply mud to mixing hopper for new mud mixing application.

Charge Pump: 1 or 2 set charge pump will sit beside mud pump for charging application.

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
 

How solids control 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 impeller to the streamlines which means that, all separate flow will be uniforms (this approximations of physical reality to get the simpler as solid state mechanism than hydraulic mechanism

General explanation: Like most pumps, a centrifugal pumps convert rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through 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, section of the casing decelerates the flow and further increases the pressure

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

Solids control centrifugal pump types

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
