Coupling for solids control rotating equipment

Meaning of Coupling for solids control rotating equipment

Coupling for solids control rotating devices are utilized for the bond of two axes (the driving shaft and also the driven shaft), allow the 2 axis rotating together and also to transfer torque. Within the transmission of high-speed and high load rotating system, the coupling have purpose of buffer, damping and enhance the dynamic performance from the shaft. Coupling includes two parts, correspondingly associated with the driving shaft and driven shaft. The majority of the general energy machine by way of coupling using the work machine connected.

Solids control equipment with coupling design

Normally, the rotating speed with shaft or axis will require Coupling, like

1) Mud agitator: It's lower speed rotating equipment. Normally, the rate is just around 60 or 70 revolutions per minute. It's use to agitating the drilling liquids in tank and eliminates the mud from settle lower. Per different tank inner dimension, the mud agitator motor energy differs from 5.5hp ~30hp. In some instances, to be able to have more compact design, coupler may also be not used.

2) High-speed/low speed decanter centrifuge: It's high-speed rotating equipment with speed around ~4000 revolutions per minute. Decanter centrifuge is use high-speed to create high G pressure, and utilize our prime G pressure to split up the fine solids from drilling liquids. Is dependent on several centrifuge model, the separation point is between 2~5 microns or 5~7 microns.

3) Different model pumps: centrifugal pump, submersible slurry pump, screw pump, and so forth.

4) Screw conveyer for drilling cuttings transfer.

Along with other rotating equipment.

Classification of coupling for solids control rotating equipment

You will find many different types of coupling use for solids control rotating equipment, here is the standard model be utilized.

1) Flexible coupling

2) Teeth-shaft coupling

3) Universal Joint

The choice of dimension for Mud Tanks

Mud tanks are the base of a drilling mud system, regardless of oil and gas drilling mud solids control systems, or HDD or CBM or TBM, or whatever.  When there's drilling and there mud can be used, it's important to possess mud tanks.

It's not a difficult job for an engineer to create a mud tank using the modern soft-wares like AutoCAD or three dimensional drawing tools, but exactly how to assist the client to obtain an ideal tank in the beginning time? May be the asked for storage capacity of tank enough for design? GN Solids Control shares some suggestions.

1. When the first is requesting a solids control system for oil and gas drilling, this means the drilling mud comes from the well hole directly. Within this situation, we have to consider the weir height of shale shaker when selecting the peak of mud tanks. If the entire height of shaker weir and tank height is simply too large, it's possible that the mud can't fall in the pipelines from well mouth. This tip is particularly for workover rigs. For meeting customers’ different demands, GN has designed its shale shakers to supply several optional weir types.

2. Throughout transportation, what equipment within this system might be taken apart, while which equipment has to be fixed on tank and moved together? Actually, mud agitators will always be on mud tank, while shale shakers and mud cleansers will always be removed temporary.

3. Can there be any legal requirement in the users’ local for that biggest width or biggest height? This should be taken care.

4. just in case of worldwide business, the machine have to be shipped by ocean. What type of ocean shipment will the consumer accept?

Obviously, the storage capacity can be the fundamental requirement which needs to be meeting in the beginning stage. GN always believes to supply the clients with best and appropriate solution.
