Screw conveyor is also called Auger which is used to collect and transfer the drill cuttings from the shale shaker to vertical cuttings dryer or cuttings collection box for further treatment. For better operation and maintenance of GN screw conveyor, the following instructions should be followed up:

1 GN standard screw conveyor is composed of 12ft length each section, 2 section, 3 sections or 4 sections for choice. At the end of each auger, there are 2 bearings, which should be lubricated regularly. There is suspension bearing at the end of each section, which should be added grease every 2 weeks.

GN provide options of screw diameters for 12inch, 14inch, 16inch and 18inch.

2 Gearbox is installed at the end of the screw conveyor, it should be lubricated every 6 months according to the operation instructions.

3 The screw conveyor should be installed properly and carefully when it arrived at the jobsite, then placed correctly and tighten the anchor bolts.

Fixed speed centrifuge is popular with some customer in tight budget. This kinds of centrifuge is not that easily to use when you shift between different projects with different material property, or when the treating material property change and require centrifuge working with different speed. Why say like that?  Because it takes some time to change belt pulley to get different bowl speed. If the user is familiar with the process on belt pulley change, it may only takes 2-3 hours; However, if the user is not familiar with process on belt pulley change and lacking of some necessary tools, things may be harder and it may takes some days to find the necessary tools first and then, you can done the job.

1) What we need to change belt pulley for GN fixed speed decanter centrifuge

In order to service the customer better, GN Solids Control will offer one tools box containing some necessary tools for centrifuge operation and belt pulley change. The tools including but not limited to below items:

Spanner/Wrench, Grease gun, Screw nuts and screw pine, Tape, Pine wrench, Puller, Drilling Waste Management System, Arm crane Etc.

 

2) The process to change the belt pulley

 

Firstly, we need to release the main motor and put it close to the auxiliary motor;

Secondly, we need to disconnect the rubber connection between auxiliary motor and conveyor;

Thirdly, we need to remove the belt pulley with the coupling;

Fourthly, we need to disconnect the belt pulley from coupling;

Fifthly, we need to put the new belt pulley on the coupling

Sixthly, we need to put back the belt pulley with coupling back to the main motor.

Then, reverse the process one step by one step.

 

The best way is to learn the process from the manufacturer. Different manufacture with different design of centrifuge; GN Solids Control can offer jobsite service if customer request. And also, the customer can come to GN factory to learn about it.

Check power voltage to see if normal before turn the motor on.
Check all the bolts are properly tighten before turn the motor on.
Check all the shaker screen are properly secure with wedge block.
Check if  there is any foreign objects on the shale shaker.
When the cleaner operate at normal condition , there should be minimum  noise and  the operation should be smooth and steady, if there is any unusual noise, stop and check the equipment immediately.
If the connection cable between vibration motor and the control panel has been changed because of maintenance or changing motor, the cleaner will not  work effectively. It needs take off the shield at the end of the vibration motor, connect the power and observe whether the rotation directions of the two vibration motors are opposite direction. If not, then it needs adjust to be opposite direction.
When change the vibration motor, adjust the rotate  blocks on the two vibration motors to be consistent.
After tighten the bolts of vibration motor, have a check every 8 hours, if there is any loosen, tighten it.
When the vibration used for about 500 hours, inject some of specific lubricant grease(about 80g).
The control switch is explosion-proof, do not open if not necessary. If need to check for issue,  it needs turn off the power first. When check the equipment for possible issue, do not be neglected details or wrong installed, to guarantee the explosion-proof.
The wedge of shaker screen should be checked each 8 hour, if there is any issue of loosen, tighten it on time.
With compact the shaker screen, the tension force of each bolt is 5KN.
When the cleaner is used for 1000 hours, some lubricating grease should be injected into the grease box.
If the springs damaged, change the springs as soon as possible. When changing the springs, the screen box should be raised, and put the springs on the spring bases, then ease-down the screen box.

Recently, one of GN Solids America Singapore customer came to GN to inspect the mud system with a dosing system to flocculate small solids into larger ones for treatment in solids control. And in last essay, the whole system is generally introduced, and also GN solids America is introduced. In this essay, I will introduce the dosing system which plays an important role in this Drilling Waste Management, without which it may fail to separate solids in the use mud strictly in compliance with the customer’s requirements.

Dosing is define as the below in Wikipadia. Generally, dosing means to feed chemical or medicines into a process fluid in small quantity, or to living being at intervals , or to atmosphere at intervals to give sufficient time for the chemical or medicine to react or show the results. For this system, the first feeding to fluid is adopted, and show the final result of small solids being flocculated larger ones for easy separates.

The whole dosing system is divided into 2 tanks(www.watertanks.com). The flocculant in them is fed into the decanter centrifuge through a screw pump in turn, at the same time ,the mud after processed by desander is fed into the decanter centrifuge through the other screw pump. With the flocculant, the ultro fine solids become larger ones which are more easily to be separated out. This dosing system is totally automatic controlled. Once the required concentration is set by man, the dosing system will works with the automatic controlled chemical feeding and water feeding. After the one tank is filled, the valve will be closed automatic, and then the other tank will open.

With this dosing system, ultra fine solids will be consolidated larger ones, which can be removed out from the mud through a GN decanter centrifuge.

Abu Dhabi Oil Show is one of the most important oil shows in world, GN Solids America, since its establishment by year 2007, has attended to this event for several times, always took with them the most popular equipments. Some GN customer got to know GN in Abu Dhabi and later visited GN company for further cooperation.

 

This year, for year 2014, GN also have a booth there, and this time, GN is planning to bring the most popular model GNLW363 Decanter Centrifuge, fixed speed decanter centrifuge with a high speed.

 

Comparing with VFD Control GNLW363, which shares same series model as the one for oil show, the fixed speed one has its common points and its own features.

They are in common in those features:

1. Same bowl diameter: 14 inch diameter, most popular size world widely.
2. SKF bearings original Sweden. GN always choose best parts for its mud cleaner.
3. Same bowl material SS2205 for main part of bowl and SS316 for other bowl parts.
4. Tungsten carbide tiles for impeller protection, better for wearing and easier for later dynamic balancing
5. Tungsten carbide tiles for solids discharge ports.
6. Easily adjustable liquid discharge ports
7. High speed it could reach about 3200RPM.
8. Able to separate out 2-5microns particles.

……..whatsoever, both fixed speeded and VFD control GNLW363 has exactly same main body of centrifuges.

 

Why choose fixed speed GNLW363?

A shaker screen is easy to transport and installation. The fixed speed control panel is installed on same frame of the centrifuge. Comparing with the one with a VFD control panel, this one occupies less space.

If the site condition and mud composition is stable and operator clearly knows which speed is more frequently used, it is better for one to choose a fixed speeded model. It also saves the cost for purchasing and later maintenance.

 

GN Solids America has available several options for this model, and the one for the Abu Dhabi Oil Show will be on sale to customers with sea freight to Abu Dhabi free of charge.
