GN Solids Control Equipments in Houston Warehouse
GN Solids Control is a company located in Beijing, which is 40 minutes drive from Beijing airport. In the year of 2013, GN Solids Control registered GN Solids America LLC in Houston which owns the warehouse of about 700,000 SF.
During this two years fast development, GN is getting to known by more and more oil and gas companies in USA, Canada and Mexico. GN is keeping to attend the OTC since 2011, for the customers goes to the OTC will notice GN has two booth this year: one is for GN Solids Control Co., the other is for GN Solids America.
Although GN Solids America is a very new company in USA, experienced GN engineers and manufactures in Beijing headquarter are spare no efforts to supporting the development of GN Solids America. During these two years, GN has shipped many sets of shale shakers, mud cleaners, decanter centrifuges and cuttings dryers from Chinese factory to Houston warehouse. Some spare parts such as hydro cyclones, bearings, motors, shaker screens have been send here too. For clients we keep contact for long time cooperation, we make the storage plan for them. Whenever they need our solids control equipments, we can arrange the delivery immediately. All of the solids control equipments are storage step by step.

Now GN has 3 sets of mud cleaners, 8 sets of shale shakers, 3 sets of decanter centrifuges as well as some other spare parts in our Houston warehouse. Welcome to have a look when you have time. Yesterday, we just send out one mini decanter centrifuge 223, screw pump and spare parts to our customer’s work site. And now we have one variable speed decanter centrifuge is rented working for OBM separation.
For the American market, GN can provide our solids control equipments with rental service. Customers are welcomed to buy the machine after they do the testing working and satisfied with the working performance. If you are interested with our solids control equipments, please feel free to contact us at thomas@gnsolidcontrol.com.

Several notices to use GN decanter centrifuge
As more and more GN decanter centrifuges are using in the oil and gas industries for the drilling fluids management and water recycling, GN decanter centrifuges are helping more and more clients to protecting the environment.
Now GN Solids Control is manufacturing about 250 sets to 300 sets every year, most of these decanter centrifuges are using over abroad. In order to fulfill customers’ demands, GN usually sends out our engineers for the after sales service. 

There are several things that the operators need to know:
1. The wire connections need to be fully correct. Any wrong connections may lead to the damage of decanter centrifuge, and the separation work can not be reached.
2. The liquid discharge port should not be changed without allowance. For uncertain situations, we recommend to place a catching tank in the bottom of the liquid discharge port. Once the pipe connected with liquid discharge port is too small, fluids will be flooded from the small end and the VFD control panel will give a stop signal to the main motor for protection.
3. The initial feeding capacity should be too large. Although GN decanter centrifuge can deal with 130 GPM, different OBM or WBM has different density so the treating capacity is not always the same. For the clients have no idea about the feeding capacity, we recommend to give a relative small feeding capacity at first. If the solids discharged from the solids port is pretty dry, the feeding capacity can be increased. On the other side, if the solids with too much oil or water after being treating by decanter centrifuge, the operator should decrease the feeding capacity a little bit.
4. Clean the decanter centrifuge thoroughly after you finish the separation work every day. Keeping feeding some clean water into the centrifuge, some solids left in the collection box will be cleaned. And after the cleaning, spin the centrifuge manually to let the inside water come out.  

The Operation of GN Variable Decanter Centrifuge
GN Solids Control has been working on designing and manufacturing decanter centrifuge for many years. Now there are about 250 to 300 sets decanter centrifuges are provided by GN to over 60 countries.
GN has upgraded their decanter centrifuges to the third version; all the modifications and upgrade are all made carefully by the experiences gained in the worksite. GN technicians are devoted to give the best solutions for worldwide clients. Until now, GN is the first Chinese manufacture that can provide decanter centrifuge and cuttings dryer together. With many years and thousands successful projects, GN are providing the more and more perfect solids control equipments (shale shaker, mud cleaner, decanter centrifuge, cuttings dryer etc).
In order to use GN decanter centrifuge well, today we would like to share you some info on how to operate it.
Before testing running, the operators need to disassemble the fix belts and supporting brackets on the bowl. All the belts and brackets are used for safety transporting. GN provide stand to support the whole decanter centrifuge in a proper height. Operators need to find a good locate the decanter centrifuge with stand. 

All the wires that connected to the VFD control cabinet is using air plug, and the four inside ports are used for connecting the power lines and ground line with the VFD control cabinet. Make sure to put the four ports in a right direction first. 

After read the decanter centrifuge carefully, you can run it according to the instruction. Check the rotating direction of the two motors, and make sure they are running the same direction as the red arrow showed on the case of the motors.
For the second version decanter centrifuge, you need to flush the rotating bowl and propeller some time after finishing the separation every day. Generally speaking, most of the decanter centrifuge broke down are caused by solids blocked in the bowl.  
Lubricate the necessary parts as the instruction says. A good maintenance can help to expand the life span.
Whenever you have problems, feel free to contact with GN immediately.

Thepurpose of decanter centrifuge is performing separation ofsolids from liquid.
For various reasons, liquid often contaminating with many solids objects
and some type of solids objects are harmful.
The decanter centrifuge use principle
of gravitational force through continues rotation in
vertical, horizontal and conveyor centrifuges.
Depending the RPM of the decanter centrifuge motor, it can produce the
rotation force in 1000 times and beyond on normal gravitational force. The separation time need it from minutes to
hours. The bowl tube that equip with
internal conveyor rotate in extreme high speed that moves in same direction but
at different velocity to achieve solids separation from liquid.

Many
industrial job use decanter centrifuge to perform separation and purification
purpose, some examples are environmental, medical, chemical, food, oil and gas
industry are commonly use this method for different purpose but achieve same
goal: the separation of solids from liquid. In fact, without this step of process, these
industries will not achieve more specific tasks because it is the most the
first step of process.

These
are steps of how decanter centrifuge separate solids from liquid:

1.      
The mud is enter the centrifuge
from connection of pipe

2.      
By an internal feed space, the conveyor push the
mud through a nozzle into the bowl

3.      
The rotation of bowl in high speed that makes
gravitational forces

4.      
High rotation speed separate solids from mud in
times

5.      
The conveyor makes solids upward and discharged

6.      
Solids removed
and clear water released from different output

The ability to purify
a liquid makes decanter centrifuges ideal for waste water treatment facilities.
However, there are varieties of industries for which such centrifuges play an
important role. Similar to other decanter equipment, centrifuges are simple to
install or use as stand-alone machinery that do not need permanent mount.

GN takes necessary measures for transporting protectionGN Solids Control has one branch company in Houston, TX. Some solids control equipments such as GN Shakers, GN mud cleaners and GN decanter centrifuges as well as some other spare parts such as GN shaker screens, GN mud guns, GN mud agitators are also stored.Experienced engineers have been sent to Houston branch for the after sales service and training work. GN is trying to provide excellent after sales service in the America market.Now all the solids control equipments are manufactured in Chinese factory in advance, then they are shipped to Houston warehouse. In GN Solids America warehouse, GN engineers will do some assemble work and test running work, every equipment will be fully tested before they are transported to our clients’ worksite. 

As many parts are quite vulnerable in transporting without some protecting measures. The principle of GN solids control is providing the brand new equipments with best quality. So GN engineers will take some necessary measures to keep solids control equipments in a very good condition.
Take GN decanter centrifuge as an example, due to the rotating bowl is quite heavy the two supporting bearings will be destroyed when its keep rotating on the way. So GN engineers will use two cloth belts to tighten the rotating bowl, and two steel bows are supporting the bowl and lighten the heavy load for the two bearings.
The Cover of the decanter centrifuges will be locked with bolts before transport. In order to move the decanter centrifuge conveniently, GN engineers fixed it on a wooden pallet. Some parts will be fixed on the pallet such as discharging port. VFD control panel will be located on a wooden pallet just like the decanter centrifuge.
Some other equipments such as shale shakers, they will be fixed tightly with large bolts in case they are vibrating during transporting.
