GN Solids America LLC's desilter

The desilter is the third step control equipment of the whole solid control system. Desilter function is to deal with the solid debris with diameter of 15-44um, and to ensure a proper treatment of the processed drilling mud in the next step.

Initial preparation of the desilter

Put the desilter base horizontally and use four pressing plates to fix the base on a suitable place of the tank. Take a note that the outlet of screen box should be 20-30mm out of the tank.
Connect the inlet and outlet holes by hose or steel tube. The inlet pipe needs to be fit with outlet pipe.

Loose four vibration bolts. When transport, the bolt need to be secure.
Check there is any bolts that are loose. Check the vibration rotating axis is moving smooth. If there is any fault noise, the problem should be solved at that time. After all the initial check that all things are function properly, the equipment can be starting to work. 
Connect the belt with motor and turn on the power, check whether the rotating direction of motor is correct.

The operation of desilter

Start with the shale shaker first, then turn on the desilter. Check whether the exhaust pressure can match the requirements and check the results of separating, check whether there is any possible of leaking.
Check the rotating direction of motor is consistent toward to the arrowhead on the shield.
Check the pressure gage works properly in an allowed pressure range.
Adjust the bottom flow nuts to make the bottom flow jets shoot the mud out smoothly.
When stop the operation, the drilling fluid should be cleaned out to avoid solidification. Clean the shaker screen with water and check each part.

The maintenance of desilter

Check and confirm the connection and sealed parts.
Check the cyclone cylinder to see the jet situation and pressure.
Repair or change the damaged, leaking or abraded cyclone cylinder.
Check whether the jet nozzle is broken. Check the inside of the cyclone cylinder and if need, change the damaged parts.
Clean the feed head.
When stop using for period of the long time, every part that contains drilling fluid should be cleaned through, avoid stockpile of sand inside the equipment.
The lubricating grease should be injected into the vibration motor every 1500-2500 hours. The volume to be injected each time is 5-10ml.
When stop using, the shaker screen should be cleaned with water to avoid solidification to ensure max useful screen life.


GN Solids America LLC's shear pump's function in the whole drilling mud recycle system

Shear pump contain following parts: impeller, vortex shell, transmission shaft, belt pulley, belts, motor and bearing.  The impeller of the shear pump is totally different compare with other pumps due to its function, shearing the objects.  The impeller which contain high cutting efficiency that have 5 structure parts: axial flow turbine, reservoir, wheel for pump, plenum chamber and cutting plates. The whole parts structure in stainless steel that has compact structure for it. 

The flow axial turbine is for fluid with displacement and for pump and the tank. 

The fluid flow through the pump wheel is discharged into the vortex shell, and the half of fluid is absorbed by reservoir. The fluid flowing through the pump wheel is parallel to the shear plate flow and has a high flow rate.

The fluid mixed with the shear pump wheel in a higher flow rate, and the high speed rotation of the shear plate is serrated, and the fluid that contain solid is sheared. By this way of process, the fluid flowing through the impeller, subjected to multiple shear.

The seal of the Shear pump with a very reliable mechanical and to make sure no leakage.

The pump turbine is mounted on a specific base plate and is move by a belt pulley. A  V belt in narrow design drive an IEC explosion proof certified motor, and a mixing hopper with a size suitable for use with the shear pump is composed of a completed shear and hydration system.

GN Solids America LLC's JQB series shear pump with specific purpose of whole solids control system that can meet all system operators drilling fluid preparing for well drilling. It can makes the mud to obtain good rheological properties and reduce the cost of drilling as much as possible.  

Oil Sludge Separation System to Kuwait

Oil sludge separation system is ready to deliver to Kuwait. It is used as the 1st stage of an oil recovery project of KOC for which a local service company makes the purchase from GN.

Component of the oil sludge separation system are listed below:

1 ea x GNCD930 Vertical cuttings dryer

4 ea x GNZS703D double deck shale shaker

5 ea x V-hopper with screw conveyor assembly at the bottom

10 ea x various pumps: shear pump, centrifugal pump, submersible slurry pump

To prevent cold weather in winter, the systems are combined with steam lines.
