Oilfield centrifugal pumps are widely used in drilling fluid solids control. Centrifugal pumps in China, also known as sand pumps. Centrifugal pumps are widely used in oil well drilling muds and equipment devices, such as shale shaker, desander, desilter.
Common centrifugal pump applications include water, sewage, petroleum, and petrochemical pumps. The reverse centrifugal hydraulic potential energy function is converted to mechanical rotational energy of the fluid turbine.
Centrifugal pump is a subclass of the dynamic energy absorption axisymmetric turbomachinery. Centrifugal pump for delivering a fluid to kinetic energy is converted into rotational kinetic energy by the fluid flow. Typically rotational energy from the engine or an electric motor. Fluid along or near the rotating shaft into the pump impeller, accelerated by the impeller, flows radially outwardly diffuser or volute chamber (casing), and flows from there.
| Model | Flow Rate | Head | Power | Speed | Efficiency |
| APSB8x6-14 | 320 m3/h | 40m | 75KW | 1480rpm | 65% |
| APSB6x5-13 | 180 m3/h | 34m | 45KW | 1470rpm | 60% |
| APSB5x4-12 | 90 m3/h | 30m | 22KW | 1460rpm | 60% |
Application of classical mechanics theory, it is assumed viscosity of the liquid is equal to 0, and the process energy is transferred from the impeller to the flow line in no loss of energy, which means that all of the separate streams is uniform (which is the approximate physical reality, can be reduced to a solid ) Mechanism than a hydraulic mechanism
Overview: As with most pump, a centrifugal pump generally rotational energy (typically from the electric motor) is converted into movement energy of the fluid. Part of the energy is converted into the kinetic energy of the fluid. Fluid axially through the perforations into the housing, the impeller blades are captured and rotated radially outwardly and tangentially until all fluid entering the housing through the peripheral portion of the impeller portion of the diffuser. Simultaneously obtaining the fluid velocity and pressure through the impeller. Donut-shaped diffuser or volute casing portion decelerate the flow rate and further increase the pressure
Drilling fluid solids control system, as a centrifugal pump. The main drilling fluid pumped into the hydrocyclone desander, in addition to mud force cyclone. They can also be combined together with the mud bucket mixer or mud mixed slurry injection pump. Pump power as a conversion tool.
Drilling fluid solids control requests many centrifugal pumps to be fit on mud tanks. According to function, we call centrifugal pumps 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 pumps and vertical centrifugal pumps. The difference is motor installation direction and pump feed inlet position.
To select either of the installation ways we need to consider the actual operation condition and general space. Presently, except installation way, there are different types of the pump on the seal. The mechanically sealed pump is more popular since the stable performance and reliable quality
We may face many different problems during the pump operation. Please contact us for further information or support. We Aipu solids control will do come to you with optimal solutions
Trip Pump: The trip pump will sit at the trip tank to transfer mud from the trip tank into the drill hole directly in special conditions. The pump is normally driven by an 11 or 15kw electrical motor with a 4×3 size pump. The mudflow 200 to 250GPM is enough.
Desander & desilter feeding pump: It is normally an 8×6 size pump driven by 55kw motor for 1000GPM mudflow for oil and gas drilling, but a 6×5 or 5×4 size pump with the smaller electrical motor will be used for smaller mudflow capacity for oil & gas drilling, coal bed methane drilling, horizontal directional drilling or water well drilling.
Water pump: The water pump will set on a water tank with a water line supply to the solids control mud tank. A diesel pump may work as a standby in case of fire.
Mixing Pump: The mixing pump normally 8×6 size driven by a 55kw electrical motor to supply mud to the mixing hopper for new mud mixing application.
Charge Pump: 1 or 2 set charge pump will sit beside mud pump for charging application.
Centrifugal pump is well used in drilling mud process system because it’s a high efficiency, easy maintenance, and cost-effective. AIPU Solids build a complete line for drilling mud process system as well as all sizes centrifugal pump. Please contact us freely for inquiries or technical support.
