For more information of CIPPE 2018, pls check : http://www.gnsolidscontrol.com/drilling-fluids/welcome-to-gn-booth-for-the-2018-cippe-beijing-oil-show


We welcome you to visit GN at CIPPE 2018 in Beijing and visit GN factory where is 30km from the exhibition center during the oil exhibition.
OTC 2018 general information: for more information, pls visit their website: http://2018.otcnet.org/
Show Time & Location: 30 April – 3 May, 2018. NRG Park, Houston, Texas, USA
Booth No. 1: NRG Center 1369-1 (GN China)
Booth No. 2: NRG Arena 8000 (GN America)
What equipments will GN show at OTC？


Decanter centrifuge GNLW363C, this is the best sold model decanter centrifuge among all the decanter centrifuge models.
Shale shaker: GNZS594F-HB, we have many sets of shale shaker and mud cleaner in stock in Houston warehouse for immediate shipment, we install Martin brand vibration motor made in USA and assembly in our warehouse.
Sludge Vacuum pump:GNSP-20A, this is our new products in 2018, we have sold GNSP-40A vacuum pump for drilling cuttings transfer and dredging slurry transfer for dredging slurry separation system, sometimes the vacuum pump may not be suitable to transfer the oil sludge based on the sludge density and viscosity and the depth. GNSP-10A & GNSP-20A vacuum pump is the new designed model to meet the client’s requirement for smaller treating capacity.


Mud cleaner: GNZS594E-2S12N
Centrifugal pump, the installation dimension, outer dimension and spare parts are all interchangeable with Mission Magnum centrifugal pump.

Sources and Sizes of Drill Mud Solids

There are 2 main sources of drill solids
particles are the chemical additives and formal drilling cuttings, the drilling
cuttings are containments that degrade the performance of drilling mud. The
drilling particles will be ground into smaller and smaller and become more and
more difficult to remove from drilling mud if the drilling cuttings that not removed as per guide. Most of the
formal drill solids will be able to be removed by mechanical ways by drill
solids separate equipment and small drill particle will be very difficult to
remove and will have a great effect on drilling mud properties than the very
larger drill solids particles . The solids particle size in drilling mud
incorporated into drill mud will be range from 1 to 250 microns.

 The clay, colloidal and bentonizte will be
size between 1 to 5 microns, silt, barites and fine cement dust will be 6 to 44
microns, fine sand will be between 44 to 74 microns, API sand will be 105 to
149 microns, coarse sand can be 500 – 1000 microns, coarse that larger than
2000 microns, there will be colloidal that bellow 2 microns.

Drilling solids particles are the main contaminant
in the drilling mud, so the control of the importance of the good solids
control including increased the penetration rate and reduce mud cost, reduce
water requirement, reduce mixing problem, reduce differential striking, etc.
The drilling solids removal is important to keep drilling mud recycling and re-use.
The
main equipment for drill solids removal are shale shaker , desander, desilter, decanter centrifuge and there will be other
machine assistant to meet separation application including mud tank, centrifugal pump, valve and pipeline.

GN Centrifugal Pump to Deliver Drilling Fluids

GN solids control distinguishes
itself from other China’s manufacturers by its cost-effective product with
competitive price to USA/EUEOPE brand but with fine and stable performance.
Beside supplying solids control equipments such as shale shaker, desander, desilter, mud cleaner, and decanter centrifuge, GN solids
control also supplies centrifugal pumps to deliver drilling fluid.

With stable performance and long service
life, GN SB series centrifugal pump is designed to deliver abrasive, viscous,
corrosive media, especially drilling fluids and industrial slurry. The pump can
handle large volume flow up to 320m3/h, withstand high temperature, and
remarkably save energy, but is easy to maintain. Currently, GN centrifugal
pumps are operating widely both on onland and offshore drilling rigs around the
world. Taking drilling fluids’ condition into consideration, we are committed
to offer the best solution to our customers.

The housing of GN centrifugal pump is thicker,
heavier and solider because of the special strength when compared with
conventional pumps, thus enjoying a more durable and longer service life.

The annular flow channel inside the housing
will eliminate turbulence and cavitation, also reduce radial load on the
bearing. The housing gasket is recessed to prevent fluids from leaving the
impeller. In oil and gas field, centrifugal pumps are mainly used as feeding
pumps to desander, desilter or mud cleaner, mud mixing pump, and supercharging
pump to mud pump. Regarding to the first application, the liquids discharged
from shale shaker will be delivered to the desander, desilter or mud cleaner by
the centrifugal pump, always horizontally installed on the skid of mud tanks.
To the second, the chemical will be added when the centrifugal pump discharges
the fluids out, usually fixed below the mud mixing hopper, also on the skid of
tank. For the third, the centrifugal pump will be used as supercharging pump
for mud pumps.

Centrifugal pump Mechanical seal

There mainly 3 sealing types for centrifugal pumps, like shearing pump, sand pump , slurry pump, etc…

1) Asbestos packing

2) Arid seal

3) Mechanical seal

Mechanical seal is the greatest and many costive sealing types. It’s reliable with an extended lifetime.

The fundamental meaning of Centrifugal pump Mechanical seal

Mechanical seal is the seal device for rotary machines. Like centrifugal pumps, centrifuges, reactor along with a compressor equipment. Since the transmission shaft goes through within the inside and outdoors from the equipment, so, the presence of a circumferential clearance between your shaft and also the equipment, equipment of medium leakage outwards with the gap, when the equipment within the pressure is gloomier compared to atmospheric pressure, air towards the equipment inside leakage, and for that reason it has to possess a package to avoid leakage from the shaft. Many seal species, because of mechanical seal has the benefits of little bit of leakage and lengthy service existence and so forth, so in present day world, mechanical seal is sealed within the primary shaft from the equipment. Mechanical seal can also be known as the face area seal, within the relevant standards from the condition is understood to be: “by a minimum of a set of finish faces vertical with respect towards the axis of rotation within the fluid pressure and also the elasticity of compensation organizations (or magnetic) device function and coordination of auxiliary closes to help keep integrating carefully relative sliding form to avoid fluid leakage.

Review of concepts on Centrifugal pump Mechanical seal

Mechanical seal is as simple as a set of or number around the vertical axis for finish face relative sliding within the fluid pressure and also the compensation mechanism of elastic (or magnetic) under the act of coupled with keep adhering auxiliary sealing and leakage potential to deal with seal device.

Common mechanical seal structure comprises an immobile ring (static ring) 1, rotating ring (dynamic ring) 2, 3 elastic components, a spring chair 4, fastening screw 5, a rotating ring auxiliary seal ring 6, and also the static ring auxiliary seal ring 8 along with other components, anti rotation pin 7 is bound around the cover 9 to avoid static the rotation from the ring.

Rotating ring and also the stationary ring is frequently may also based on when they have been the axial compensation capacity and it is known as the compensation loop or non compensation ring.
