Dual voltage drill mud treatment equipment

Many customers are interested in dual voltage equipment, they prefer dual voltage mud agitator, dual voltage shale shaker, dual voltage decanter centrifuge, dual voltage sand pump, dual voltage slurry pump. And dual voltage motor starters. In this case, they can use the same equipment for different power system project in case they need it.

Mostly in China the solids Control and drilling waste management equipment are designed for single voltage power system. As the dual voltage motor is not popular in China. Few companies can make dual voltage motors. It is hardly to find the reliable suppliers. There are some European and U.S brand offers dual voltages motors, but price is much higher. Normally, it is 2 or 3 times higher than the normal Chinese brand single voltage motors. It will be more cost effective for clients to buy another set of motors as backup.

decanter centrifuge and shale shaker 

If clients really want the equipment suit for dual voltage and suits for both 50hz and 60hz power system, GN Solids Control will recommend them to buy equipment per 60hz power system. In case they use the 60hz motor in 50hz power system, like for both 460V/60HZ and 380V/50HZ. The equipment rotating speed will be lower from 60hz to 50hz. Theoretically the lifetime of the 60hz motor running at 50hz will a little bit shorten the lifetime. But it will not shorten much. Compared with the big price margin on dual voltage motors, it is much more cost effective.

But the 50hz motor equipment is forbidden to use for 60hz system to avoid over speed and damage the equipment, or to cause dangerous.

For motor starter (electrical control panel), it is not problem to make it for dual voltage, like to suit for both 460V/60HZ and 380V/50HZ . The control panel will suit for both 50hz / 60hz. So you can use the agitator for 380V/50HZ. There will be a transformer on the control panel. And there will be a switch on the panel. Operators will shift the control between 50hz and 60hz by moving the switches.

How to order the right screens for shale shakers

There are many different types of shale shaker models. Every shaker has its own design for shale shaker screens. Even for the same shale shaker brand, they may have different screen design for different serial shale shakers. And the screens are not interchangeable in most cases. How to ensure that you order the right screens for your shale shaker?

1) Firstly, you have to ensure your shale shaker screens are hook type or frame type. Like all Derrick shale shaker screens are hook type. While Mi-Swaco, NOV Brandt and Fluids System shale shaker screens are frame type. For the popular shale shaker models, once you mentioned your shale shaker model, the screen supplier should know what is the right replacement screens for your shale shaker, like for Derrick FLC serials shale shaker, MI-Swaco Mongoose serials shakers, Brandt Cobra shakers, GNZS594 shakers.

2) Secondly, there are flat type screens and Pyramid screens. Pyramid screen is an old fashion. During that time, the manufacturing technology is very limited. So people been told that the Pyramid screens can offer more usable screen areas. So in many case, Pyramid seems popular. But actually, the pyramid screen lifetime is normally not as reliable as flat screen. And in fact, mostly the drilling fluids cannot go up to the top of the screen pyramid. So PMD screens cannot enlarge much screen usable areas. Now with the development of screen manufacturing technology, the composite flat screen can offer a bigger usable screen area compared with the old processing.

3) After you confirm which screen models you need for your shale shaker, it means the screen dimension are confirmed. It ensures the screens can fix for your shale shaker. Then you have to choose the right screen opening for your applications. API size is the most popular and the international standard to definite screen opening. For different screen manufacturers, the same API size screen means the same screen opening range, it is interchangeable.
Sometimes, people may mention mesh size for screen, But it is not actual. Mesh relates to a piece of woven wirecloth, is a measure of the number of holes in a linear inch (such as 100 mesh) or in a linear inch in each direction (such as 100 x 60 mesh). It has no meaning to the screen openings.

MI Swaco Screen Pulse VS GN Solids ViST Vacuum Shaker Screen

MI Swaco Screen Pulse system and GN Solids ViST Vacuum Shaker screen are both designed for enhance the performance of the shale shaker to recovery drilling fluids. Generally speaking, the function of the two system is same, the working principle and process is different. MI Swaco has it’s own patent and GN Solids ViST also has it’s own patent design.

Both system can be used for oil based mud, water based mud and SBM.

About the MI Swaco Screen Pulse Technology
The MI Swaco SCREEN PULSE fluid and cuttings separator is a vacuum system to enhance shale shaker performance by creating a suction effect under the screen surface, reaping all the benefits of ultra-fine screen separation efficiency. A catch pan will be installed as a drop-in, within the shaker bed underneath the last screen on the shaker; an air valve mechanism is attached to the catch pan and creates vacuum suction force, pulling all the residual drilling fluid from the drilling cuttings surface as they travel towards the discharge end of the shaker.

About GN Solids ViST Vacuum Shaker Screen

ViST is Vacuum Screen Technology is to work with shale shaker to reduce drilling waste and recycle drilling fluids.
ViST was pending patent design developed by GN Solids Control from June, 2017. In May, 2018, GN tested ViST with drilling fluids. It proved to be very efficient for recycling drilling fluids.
The ViST Pan is installed under the last screen or mounted externally. And a suction hose is connected to ViST vacuum unit. The compressed air from air compressor or the rig air supply is required to create suction on the last screen surface, pulling additional fluid off the cuttings. It can reduce the liquid on the cuttings by 30-50%.

Main difference between MI Swaco Screen Pulse and GN Solids ViST Vacuum Shaker Screen .

Firstly, the Mi Swaco Screen Pulse System utilize a special valve mechanism to create vacuum for the catch pan. But GN ViST vacuum shaker screen use a vacuum pump unit to create vacuum for the catch pan.

Secondly, the Mi Swaco screen pulse system collect the drilling fluids and discharged directly to the mud tank by the valve mechanism. But GN ViST vacuum shaker screen collect the drilling fluids and sent to a vacuum unit, and pushed out by the compressed air.
