GN Nodig Mud Recycling System

In Solids Control equipment, centrifuge is the highest tech equipment, espacially comparing with shale shaker, mud cleaner, etc. So there are always something you need to know before you purchase, or before the operation, to make yourself more confident on explaining, or running.

1) Explain the centrifuge each components and function.
The centrifuge including collection box, bowl, screw conveyor, motors, control panel etc.
The most advanced material of centrifuge so far is the SS2205, duplex material. For bearings, we all know SKF one, but need to be the real SKF one. As heard of, the real SKF also have different class, made in China, made in Australia, and made in EU.

The screw conveyor can also rotate through gearbox input speed. Another end of gearbox is fixed by bolts, no rotating.

The differential speed calculation formula: N= (N1- N2) / 57

N1: means bowl speed

N2: means screw conveyor speed. In this centrifuge, it is 0.
57: means gearbox differential speed ratio.

2) The function of the rotation button. How to adjust the button to increase or decrease the bowl speed?
3) Preparation of the test; how to connect the centrifuge, VFD control panel and feed pump?
4) Check what is feeding into
5) Know the result you want, and what you are expecting to get from the centrifuge

The last but also one of the most important thing
6) Know more about your supplier
Who are they?
How they manufacture the centrifuge? As a solids control equipment supplier, GN Solids Control is the only one who have the double column CNC machine, which can do the manufacturing from 5 sides of each piece.
How can the manufacturers assure the centrifuge accuracy?

This is just a reference questions list, can not help you figure out everything, but if all sorted, will not be too bad. And contact GN Solids Control if any questions.

Drilling mud serve as lubricant that keep the drilling bit operate smooth.  The consequence of drill bit overworked by temperature heading up will lead to hard work of engine and transmission that lead to breakdown and halt the whole operation.  It is a very costly operation halt that leads cost of extra ten thousand of dollars and more. Plus, the drilling fluid is also a very costly lubricant and to keep the drilling cost under control, solids control machinery is need for filter the debris that contain in the drilling mud for many times of cycle of use the drilling mud.  The 5 filtration machineries that will completely perform filter the solids from the drilling mud are shale shaker, vacuum degasser, Mud Gas Separator, desander, desilter and decanter centrifuge.

The filter step goes in below:

Shale shaker

The drilling mud feed enter the feeding box of shale shaker.  The mud contains various size of the solids return to the ground surface and shale shaker is filtering the biggest solid by use high G force of shaking.  The box of shale shaker contain panels of mesh screen that is different number of mesh depend on solids contents analyze by drilling mud engineer

Vacuum degasser

. The muds that return to ground surface not only contain solids but also gas from the earth core.  This gas that change density of drilling mud leads result change the viscosity of drilling mud. Vacuum degasser removes the gas in the drilling mud to keep the mud in balance and continue the future solids filter process.

Desander

The drilling fluids now that contain medium size solids enter the liquid feeding pump and enter the desander, which contain large hydrocyclone(s).  The solids diameter above 40-60um will be filtered and bottom of desander is pair with shale shaker contain finer mesh compare with first shale shaker to complete the filtering.  T

Desilter

This machinery’s function of work is just as same like desander in last step before. It contains multiple smaller hydrocyclones that can remove solids that measure diameter above 15-40um.  It is also pair with shale shaker like desander and completes this step of filtering.

Decanter Centrifuge

The drilling fluid feed through centrifugal pump that feed into decanter centrifuge that rotate in High speed of G force.  The rotating bowl will separate solids from the mud and exit in one for solids and other one is for filtered mud.  The drilling mud now will feed back to the rig for next cycle of usage.

As a top manufacture of Solids Control Equipment, GN Solids
Control has been constantly expanding its business & influence in global
market.

As 1 of the core products of GN Solids Control, the Decanter
Centrifuge is one of the most popular products for global customers. As we all
know, the decanter centrifuge is usually for separating the very fine solids
particles from slurry or mud at high speed, which is widely used in the
drilling field, industrial application, etc. But duo to its complexity and high
requirement for the manufacture process, especially for the high speed decanter
centrifuge, to some extent it belongs to a high-tech product and was under
control by companies from America, Switzerland, etc.

 

Since GN Solids Control was established in 2007, GN Solids
Control has focused on researching & manufacturing the high-speed decanter
centrifuge. By through the constant research and improvement, because of its
