Maintenance highlights of decanter centrifuge

While
operating well drilling, the drilling
fluid centrifuge machinery is one of the central
equipment that is often used, its purpose is mainly used for separating fine
solid debris whose diameter size are 2-7 μm from the drilling fluid.   By using the drilling fluid centrifuge to
remove solid debris, it can effectively well lubricate and protected the drill bit;
it also has a very important role of improving drilling bit speed. With the oil
drilling industry ways and the technologies are getting mature; the drilling
fluid centrifuge manufacturing technology has been greatly improved as well.
However, there are some inherent mechanical issues if not solved it will give
the operators many function issues.

We as
manufacturer often have seen operators encounter issues below:

1. Bowl fault.
2. Consumable parts (inlet pipe, shockproof strip) problem.
3. Excessive vibration wile machine is currently working.
4. Outlet blocking by solids wish to remove from fluid.
5. Explosion-proof plug damage.
6. Centrifuge scroll damage.
7. Bearings failure while process of operation.
8. Drilling fluid centrifuge hoses damage.

We as
manufacturer suggest below if such issues operators encounter:

Operators
must understand that regular maintenance on the centrifuge such as regular
cleaning the inlet and outlet by filling water or diesel depends what kind of
fluid it needs process.  It is also
crucial that add grease to the bearing parts to ensure proper lubrication.

Operators
needs regularly inspect often- damaged parts on the drilling fluid centrifuge,
such like hoses. In order to ensure the process in the use of these parts in
normal way this influences the production. Finally, electronic parts of the
centrifuge are working the best by running certain period of time frame (like
none-stop for hours). It needs, reduce the rapid turn on and off of the
centrifuge. If properly operate the centrifuge like mention above, then
operators will find out centrifuge failure rate will be greatly reduced during process
the drilling fluid.

Why Choose GN’s 4 Panel Shale Shaker for Solids Control

Shale shaker is a type of very common
drilling mud solids control in all kinds of drilling projects. As a leading
manufacturer of solids control equipment, GN could provide the shale
shaker and other mud recycling equipment for oil gas
drilling, horizontal directional drilling, water well drilling, tunneling and
piling projects.

The capacities of GN’s shale shaker are
200GPM, 500GPM and 600GPM under the mud condition of density 1.2g per cubic
centimeter, viscosity 45s measured by Marsh funnel viscosimeter and screen of
API 40.

GN Solids Control has a 4-panel screens
shale shaker which is the largest model in GN’s shale shaker product line. This
model could be used at the oil rig site for primary solids control. At the
consideration of easy operation and maintenance as well as the widely accepted
treating capacity, GN made the model of GNZS594E-HB shale shaker to fully
meet the market request.

So, what are the advantages of this model?
Or we say what the features are?

1. Simple structure design of the shaker
deck, the operator could observe the work performance easily. The added extra
horizontal square steel strips at both sides of the deck make the deck much stronger.  

2. The 2 vibrators located vertically with
the beam makes there is a longer connecting face which could distribute the G
force uniformly to the whole shaker deck.

3. Hidden design of the lead screw beneath
the shaker deck makes it available to adjust the shaker deck angle while the
shaker is running. The operator only need a ratchet wrench to adjust the deck
angle from one side of the lead screw, the other side would be adjusted at the
same time.

4. To ensure the better sealing
performance, the screen frame was installed a type embedded rubber sealing.
This rubber sealing will not be taken off with the exception of manually
disassembling.

5. Wedge blocks are used to fasten the
screen panels is also a popular method. This makes the exchanging of the screen
easier.

6. Sometimes the shale shaker could be used
as a under shaker of the mud cleaner unit. All GN’s shale shaker will have the
pre cut installation holes to install the cyclone frame. Which means GN’s
cyclone frame for mud cleaner is removable. All cyclone frame, no matter what
capacity, the installation location would be the same.

7. By changing hopper feeder, GN’s 4-panel
shale shaker could be used as a drying shaker for waste cutting management. The
G force is up to 8.
