Drilling fluid centrifuge machine to give out heat when running because the machine needs to turn  the electricity to electric energy can be turn the rotator of drilling fluid centrifuge. A portion of the energy is converted into heat, which make the components of centrifuge generate heat. But if the centrifuge components are too hot, it can be seen that the electricity is translated too much into the heat and will cause some damage.

  1. The load of centrifuge larger the electric current, the rated power is greater than the actual power, that over part turn into so operating the centrifuge is overheating.
  1. The giving electric power is too high, and the actual need of power is fixed, the over part run off and transformed into electrical energy.
  1. The set up or starting device have issue of centrifuge, the power conversion rate of the centrifuge is low when started. If the centrifuge is set RPM too fast or starting device has issues, it can raise the power of the centrifuge.  Yet the low energy conversion rate which will make it overheating. The overheating of the centrifuge parts can greatly shorten the service life of the centrifuge by damage the bearing. Should find out the fault reason and handle it timely, or contact the centrifuge manufacturers, to carry out the technical support for the centrifuge fault processing.

GN Solids America now improve its two-phase decanter centrifuge to three-phase (liquid-oil-solids separation). It’s new development will broadly serve more industry.

  • Decanter centrifuge work reliable, long service life. The composers of the propellers -with thick plate, exterior wear resisting layer to ensure centrifuge use long life.
  • The main bearing imported SKF brand to ensure maximum time usage of machinery.
  • Centrifuge vibration is produce very low noise .By improving the rotational pars machining accuracy and the dynamic balance accuracy of the vibration.

Solids-liquid separation centrifuge have the  parts of roller, roller screw conveyor, and connection that link the drum and screw conveyor transmission composition. The roller rotate at high speed in the range of 1500 – 3500rpm depends on weight of the drum and the power of the motor. The solid-liquid  process of separation is carried out in the drum. The end part of the cylinder is provided with an overflow ports. The screw conveyor drum to both ends of the roller is conveying of solids and liquid.  It linked the differential and screw conveyer, which rotates in the same direction, and there is a certain RPM difference. Roller and conveyor speed ratio is generally 80:79, namely the roller conveyor turn to 80, turn to 79. When the drum speed is 1800r/min, the relative 22.5r/min of the roller conveyor speed difference.

Drilling fluid centrifuge is driven by two explosive-proof motors. The main motor through a belt driven drum and the outer case of the differential device rotation.  The auxiliary motor that drive the screw.  The drum and screw rotation in the same direction, and has a RPM difference. By centrifugal sedimentation separation of drilling suspension principle, the suspension is composed of a feeding pipe by screw pusher the liquid in hole of the drum.  The centrifugal force of solid particles pushed the inner wall of the drum, the spiral push feeder of the blade to push the narrow- end of the drum exit opening, while the liquid phase through the overflow hole of the drum overflow for achieve the purpose of continuous solid-liquid separation.

Comparing with other solids control equipment like the shale shaker, desander, desilter and other equipment, the decanter centrifuge clearly need more attention and more care during operation in order to make sure a good performance, especially on the 24*7 running jobsites.
As the leading manufacturer of solids control and waste management manufacturer in China, GN has been producing hundreds of decanter centrifuges and GN centrifuges are working all over the world, GN has following tips to share with the decanter centrifuge owners or operators.

a good choice of centrifuge

GN decanter centrifuge

1. Before confirming the model, collect as much as information including the those points: the jobsite condition, like the temperature, the end users’ special request like the EX standard (ExdIIBT4? IEC EX? ATEX or Gost?), the allowable max electric current, and electric specification of the jobsite(380V, 50HZ? 460V, 60HZ? 415V, 50HZ or others?). And try to collect as much information of the material to be treated, the largest particle size, the solids contents before treatment, and the allowable largest particle size and solids content after treatment. A right choice of decanter centrifuge is the precondition of its good performance. Those are GN Centrifuge Models for your reference.
2. Before installing and commissioning of the decanter centrifuge, read the user’s manual carefully and get a general idea of the specific model of decanter centrifuge and the control panel. Normally, the VFD controlled decanter centrifuge is more complicated to operate, the operator need to have both mechanical and electric knowledge to handle it, at least for operate it.
3. Assign a specific professional engineer or operator for each decanter centrifuge. His work is to observe the condition of the decanter centrifuge and discover any problem at the first time and solve it. Because the centrifuge is high speed running machine, and when the mud condition changed a bit, it affect the performance and the centrifuge service life.
4. Lubricate the centrifuge on time, especially the bearings. Like GNLW363CG decanter centrifuge, the bearings are original SKF bearing. Good bearings ensure a longer service life on basic that you maintenance them carefully. Per manual’s instruction, some points of decanter centrifuge need to be lubricated every shaft and some need to be lubricated after running some hours.
5. A standard equipment is designed for common conditions, but not for all. In some cases, the end user need to make the jobsite condition to suit the equipment, like to make some isolation for keeping the equipment warm or cool, sometimes, the end users even put the decanter centrifuge in a air conditioned room or container to get an ideal performance.
May you have more questions or need more information, welcome to contact GN freely.

Two weeks ago, GN sales team members and GN top management were back from Houston, USA. They went to Houston for the yearly oil and gas festival, the OTC Oil Show. This OTC was a success for GN. Most of GN’s equipments in stock in Houston warehouse were sold out and GN Solids Control’s name was better spread among the oil drilling and oil service companies.

After the OTC Oil Show, GN staff in USA branch has to be busy for a while for packaging the equipments and deliver them to the buyers.

GN Solids Control in OTC

GN GOT BIG SUCCESS IN OTC

This OTC, GN has two stands, one is in Chinese companies’ area. Even before GN set up the branch with name of GN Solids America in USA, GN’s brand was known to many companies in the world. Now this brand becomes more and more famous.

Of course, this is not only because of the Oil Show, the more important reason is that GN’s products are of high quality and good performance. What are GN’s core products and which are the best sellers?

  1. GNLW363CG Decanter Centrifuge. Decanter centrifuge is not only used in solids control, but also, more widely used in waste management systems. unless other solids control equipments, centrifuge shows more about a company’s producing ability. It could be used for solids control, drilling cuttings waste management equipment after the VG dryer or the high-G shaker, and also plays as dewatering centrifuge for drilling fluids.
  2. GNCD series vertical cuttings dryers. Comparing with decanter centrifuge, it is a new product. It is designed originally for the oil based mud drilling cuttings waste management. But as some GN clients are using it in water based mud also, GN now designed the 5th generation with new material in order to deal with the water based mud. Now more than 50 sets of GN vertical cuttings dryers are working in many countries in the world and the feedbacks are better than OK.
  3. GN shale shakers and high G shakers. The shakers, solids control shakers and high G shakers for waste management systems are both important, they are used to separate out most of drilling cuttings.

4. GN shaker screens. GN make high quality of shaker screens for both GN’s own shaker and other brands’        replacement shaker screens.

In the past CIPPE 2016, GN Solids Control brought its centrifuge family to the show, all the centrifuges from the 9 inch baby centrifuge to the 22 inch big brother centrifuge, standing in a row and visited by many visitors and end users.

Especially the GNLW363 Decanter centrifuge, both the old look one and the new design were shown in CIPPE 2016, and the new one was positioned on a skid. What’s the differences between each generations GNLW363’s?

1, first generation GNLW363, the original design for 14 inch decanter centrifuge, with the two motors on each side of the centrifuge. although the material used is better than others, the centrifuge is still an old looking one.

2, second generation GNLW363B, it is more international looking, as GN Solids Control has been selling its products to many countries and regions in the world, and GN’s products design became more and more international, GNLW363B decanter centrifuge’s motors are located on same side of the centrifuge, it allowed the operators to have more space for operation.

  1. third generation GNLW363C decanter centrifuge, for outlook, it is similar to GNLW363B, with two motors on one side. But there are more small but useful changes on GNLW363C, because the centrifuge was used for many applications since then, like the oily sludge separation, the dewatering unit and etc, with feedback from jobsites, GN re-designed it and better it a lot.

4, forth generation GNLW363D, the inside design is similar with GNLW363C, but the outlook is quite different, as the structure is more compact and total weight is less, easy for air shipment in case of urgent use.

For the same model of GNLW363D/C decanter centrifuges, GN has optional control panels like fixed speed control panel, VFD control panel of normal one, and the positive pressurized control panel with PLC smart touching screen.
