GN Jet Mud Mixer for Trenchless Project
As we know, at the begin of GN funding , we main serve the oil gas industry, and made the solids control equipment to treat the drilling mud for oil well drilling company. As the the company development and the technology accumulation, we upgrade our equipment to adapt different project. Such as the trenchless project ,tunnel boring, horizontal direction drilling and some other municipal engineering. Trenchless and TBM both most time also will use the mud to improve the drilling efficiency. Last week we provide 3 set mud jet mixer for treachless project.
These equipment used for China domestic project. Form the photo we can see, it include mud hopper,centrifuge pump , mud tank and electrical control panel. This is one mini mud mixing system, this design is convenient to transfer to different project site, especially when we work on city. The mud hopper used to dump mud material like cement, barite etc... it has a venturi design to generate the suck pressure to make sure the material can feed into tank and mix with water quickly. The second main equipment is centrifuge pump. GN centrifuge pump casting used ductileiron to anti wear and keep the long lifetime, the pump parts are 100% interchangeable with Mission pump. This is also convenient for our client to buy the replaced part in local market.
When the mud mixer working, the centrifuge pump suck the liquid from tank, then dump mud material into mud hopper ,material will mix with liquid through venturi ,and back into tank. There is also equipped mud agitator, the agitator can prevent the solids settle on bottom and keep the mud property. This system capacity is about 90m3/hour, and the tank volume is 6 m3,for some small project, which is enough as a mud buffer tank.
For most trenchless project, which do not need explosion proof ,but we do can provide Atex, IECex ,CNEX these different ex proof standard. If you have demand on these equipment, welcome to contact us for more information.
GN Disc Centrifuge and Decanter Centrifuge Delivery to China Client
As we all know GN has been in solids control industry for more than 15 years, and we have 3 facility more than 40，000 sq meters. Our new factory will put into production in 2021,which 60% use the robot to improve productivity and get more stable quality. We do become a leader in solids control industry, not only in global market,but also in China domestic market. In solids control and separation industry, the core equipment is Decanter centrifuge and disc centrifuge. Last week we delivered one unit Decanter centrifuge and one unit disc centrifuge for China client.
Both Decanter centrifuge and disc centrifuge utilize the separated force to separate the solids and liquid. When the machine in the high rotate speed,which will generate separated force, the bigger density material will bear bigger G force, which will lead to the bigger density material settle down the bottom and reach the separation target. As usually, the speed of Decanter centrifuge is between 2500 to 4000rpm, and the max G force can reach 3000G. The max G force of disc centrifuge can be more than 1000G. So we can see. The disc centrifuge is more widely used to extract some chemical material, bio material, or oil-liquid separation etc. And we can get more clear liquid.
When we use decanter and disc centrifuge. Usually we suggest the solids content not over 10% before feeding into decanter centrifuge ,and solids content less than 3% when feed into disc centrifuge. Other with the solids will stuck machine and affect the separate effect. In most project,we will use Decanter first to remove out more solids, and the feed into the disc centrifuge to get more clean liquid.
Both decanter centrifuge and disc centrifuge can make the 3 phase separation, separate one kind solids and 2 kinds liquid in same time. Decanter centrifuge and disc centrifuge are equipment that have high requirement to machining precision, when we choose supplier , it is necessary to choose the reliable manufacture to make sure the sable quality and technical support.
3 Sets GN Dewatering System for European Client
After more than 15 years development, GN has accumulated much experience on the separation industry. At the primary of GN history, we main focus on providing equipment for solids control equipment for oil gas company. Our equipment main used to treat the drilling mud and built long terms cooperation with some top global energy company with good feedback from them. However, we are not limited on the solids control industry for now. We developed some models especially used for waste water treatment. Last week ,GN delivered 3 sets sludge dewatering system to European client.
As you know, Europe has the most strict requirement. After several times inspect to GN company, client finalized to use GN technical solution for the water treatment. From the picture you can see, the system combined with 2 parts. Part 1 is chemical dosing unit, which is used to feed flocculant to mix with slurry. The part 2 is a mud tank and installed with feeding pump and GN 224EP Decanter centrifuge.
Client require to remove out the particle smaller than 5 micron as much as possible ,it is hard to reach this target if we just take mechanical separation, so the flocculant iso necessary to combine the tiny solids into big to easy separate by Decanter centrifuge. The chemical dosing unit can feed medicine to 3 Decanter in same time. And it can be controlled separately.
We are required by client to design the mud tank as small as we can. GN224 series Decanter is the smallest model with 9 inch diameter of centrifugal bowl. The special design of cone angel will keep the discharged solids dryer enough. Small size decanter will allow us to use a tiny mud tank to install it. All the system is full automatic and continuous work, which will save much cost of labor for client. The stable quality will make sure the less cost of maintenance. Simply operation, stable quality, automatic are the features of GN equipment. If you have demand,please feel free to contact us.
