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.

GN Solids Control is The far east leading brand of solids control equipment supplier with basic in Beijing, Houston and also Russia. And each month all of us export lots of mud devices for solids control as well as drilling waste management or even mud system to in a different country client and domestic consumers. Recently our company is fully entertained because of lots of project tools are ready for dispatch.

1) Several centrifugal pump for Nigeria client
Nigeria have a lot of oil drilling rigs in addition to oil blocks. Oil sources is rich there and have lots of clients coming from Nigeria who bought decanter centrifuge, drilling waste management straight cuttings dryer, solids control shale shaker, replacement shaker screen etc . from each of our company—GN Solids Control. Just lately, we got some small get from Nigeria who wants to change their old centrifugal sends. And we sell some models of good pump and mud agitator to them.

2) several sets of mud agitator for Egypt clients
The consumer bought this agitator is actually GN old client who have already bought 2 models 500gpm mud cleaning system for their HDD drilling. These are really happy about the mud system high quality and the dependable working performance. The 500gpm mud system is equipped with some panel shale shaker in addition to 4 panel mud cleaner. The shaker screen is actually composite material shaker screen, replacement for Swaco Mongoose shaker screen, with much better performing performance, longer lifetime and fewer maintenance. We also have additional treating capacity mud system for option. Like 200gpm mud system, 800gpm mud system and 1000gpm mud system

3) 2 models shale shaker for UAE client
Good maintenance can help you lots of cost, than shopping for new products. We give train to be able to client and let them to utilize GN equipment to greatest. And recently, we have 1 client wanting to replace the previous shakers for about 3 years. Which is really good. The shale shaker is to update the mud system the client already have over 2 years. The client buy two sets new shale shaker to update their older mud cleaning system and this is usually relative lower cost to continuing the new project. Because of the lower market, many clients want to take budget, save cost is to do more project. We highly recommend client to renew the mud system with new tools, new shaker, new centrifugal pump, new mud cleaner and new agitator. Commonly, the mud tanks last longer time if the regular maintenance is doing each time soon after use.

Composite stuff shaker screen is a kind of shale shaker screen with material material as basic shape, and use a special form of plasticmaterial to fulfill the structure.
