Brightway Centrifugal Pump

What is solids management centrifugal pump detail?
In solids management mud system, there have centrifugal pumps for hydrocyclones. The mud transfer pump for charging centrifuge, the lubricating substance compounding pump for configuration, and/or the cutting pump for shredding lubricating substance, the trip pump, etc. we have a tendency to can also say, there’s horizontal pump, vertical pump, screw pump, etc.

Different equipments request completely different pumps as power resource or mud provides. Meanwhile, {different|totally completely different|completely different} solids system configuration can have different pumps position, design, or types.
Detail pump in field solids management
For solids management equipments, the separated hydrocyclone separators or mud cleaner we have a tendency to should match pump as mud feeding pump. The centirfugal pump transfer lubricating substance to the cyclones body of water line for resultant method.
Usually, these pumps area unit horizontal one. They’ll be mounted on mud tanks ends or below the slant plate of shaker tank. ?When we have a tendency to set pumps below shaker tank can save abundant area. However, then it’ll be inconvenient once we repair or examine pumps.
But generally in solids system there’ll be vertical pump or submersible suspension pump rather than horizontal pumps.
We know in solids system, the lubricating substance appears blood to our physique. where as centrifugal pump are the transfer tools. They pump lubricating substance from here there between completely different lubricating substance tanks or compartments.Let’s see, once mud cleaner or hydrocyclone desilter what pumps there? affirmative, the fourth solids management equipment-Decanter centrifuge. For bottle centrifuge, we’d like pump transfer lubricating substance from desilter compartment to centrifuge input.

Oilfield solids control pumps

The drilling mud can be pumped by horizontal centrifugal pump, or the vertical centrifugal pump. We also may call it slurry submersible slurry pump. Some clients will also request the screw pump for feeding decanter centrifuge.

 

 

In fact, during communicate with clients; we’ll propose proper pumps or configuration for them. Upon their satisfaction on both technique and cost we’ll confirm the optimal solutions on pumps and every other issueThe mixing pump and shearing pump? They have similarity. Both them are combined with centrifugal pump and another part. And they both can mix / compound drilling fluid for solids control system.

 

 

The mixing pump is including the centrifugal pump and mixing hopper, which can be venture hopper or vortex hopper.?While the solids control shear pump including the centrifugal pump and over-head belt.

mud mixer hopper

Yes, another pump is the trip pump. It is also centrifugal pump. And we set it on the trip tank. It can supplement drilling fluid for shaker or the former equipments.

The Advantages and Characteristics of the Screw Pump

Single screw pump is an ideal equipment for the decanter centrifuge for plasma, not shear and mixing mud. The main components of screw shaft (rotor), screw sleeve (stator). The two part of the unique geometry, which generates an extrusion amount. Fee with the axial flow slurry flow rate, low, holding capacity, stable pressure, so as not to produce vortex and stirring.          The coupler is used to screw pump, or by a variable speed motor speed control, V triangular shaped belt drive, gear box etc.. G series screw pump accessories, compatible structure, small volume, easy maintenance, the pump rotor and stator is wearing parts, convenient replacement. The stator is made from synthetic rubber material, the fee paste transfer of high viscosity and suspension hard has special advantage over other pump.

Shear Pump

Solid Control System Constitution

Solids control system (referred to solid control system) is used to store drilling rig, configuration, fluid circulation and purify the major items of equipment. Generally consists of drilling fluid tank and mud shaker, vacuum degasser, Desanding cleaners, except mud cleaners, centrifuges and other necessary five purification equipment and overhead lines (from the wellhead to the vibrating screen), drilling pump suction line, mixing pump suction and discharge piping, water piping, drilling water pipeline, the base oil pipeline, the pressure fluid barrel Road, shear pump suction and discharge piping, pipe line bottom of the tank, supply pipes, discharge piping and other piping components. System is equipped with drilling fluid supply device, increasing the funnel, increase pump, in addition to sand pump, in addition to mud pumps, shear pumps, supply pumps, the screw pump, mixers and other auxiliary equipment. It also has a walkway, ladders, railings and other safety devices. It can effectively remove the drilling fluid is greater than 5-15 mm harmful solid phase, keep useful solid phase, to provide high quality drilling fluid.

The main configuration solid control system

Drilling conditions in order to protect the quality and quantity of drilling fluid needs, different types of rigs in solid control system is equipped with the (solid control tank volume, device configuration, process layout, etc.) are different.

In the solid control system design requirements, usually mud tank effective volume of 75% of the total volume. Mud tank design should meet the following requirements:

①   Mud tank should be able to accommodate a maximum during drilling fluid circulation;

②   Mud tanks should be able to meet the overall strength of lifting, transport and use of drilling fluid density of 2.5g/cm3 requirements;

③   The tank of the space requirements should be based on process, and set the overflow outlet pipe communicating with the bottom of the valve;

④   Each compartment shall be provided with clean sand mouth, opening the lower edge should be flush with the bottom of the tank below the bottom of the tank;

⑤   All seals needed to meet oil, acid, alkali H2S, can satisfy the requirements of a variety of drilling fluids.

In the solid control system design requirements, the need to configure the mud handling equipment, solids control equipment selection need to follow the following principles:

①   Shale shaker: drilling pump capacity shall be 100% of the maximum total displacement to 125%;

②   Vacuum degasser: drilling pump capacity shall be 100% of the maximum total displacement to 125%;

③   Desander: drilling pump capacity shall be 100% of the maximum total displacement to 125%; configuration sand pump and motor should satisfy the above capabilities;

④   Desilter: drilling pump capacity shall be 100% of the maximum total displacement to 125%, sand pump and motor should be configured to meet the above capacity;

⑤   Decanter Centrifuge: the drilling process is usually the maximum displacement of the 5% to 10%;
