Shale Shaker Maintenance

The first line of defense for a properly designed solids control system has been and will continue to be, the shale shaker. Without proper screening of the drilling fluid during this initial removal step, reduced efficiency and effectiveness of all downstream solids control equipmentin the system is assured. The downstream hydrocyclones will simply be overloaded beyond their designed capacity.

The first line of defense for a properly designed solids control system

The shale shaker, in various forums has played a prominent role in china solid control system for several decades. The two main shale shakers utilized in the utility industry are:

Shale Shaker Maintenance
Because of their greater efficiency & complexity the use of finer mesh screens is essential. This requires more attention than the standard scalping shale shaker screen.

Besides periodic lubrication, fine screen use requires the following care:

1. Wash down screens with power washer regularly

2. Check screens for tear or rips

3. Make sure screens are properly mounted

4. Make sure shaker is at proper angle

5. Check wiring or a regular basis high speed shakers tend to wear through wiring insulation

In addition, frequent checks must be made for plugging or blinding screens. The shale shaker angle can be increased or decreased to help eliminate this problem. For blinding screens a more coarse or finer screen may be installed to help solve the problem.

Remember your shale shaker is your first line of defense in your solids control system, Choose a shale shaker that is correct for your application and have rig personnel learn to use it correctly.

Drilling mud decanter centrifuge in Libya

There are multiple types of decanter centrifuge, which can be classified by intended use or by rotor design. Types by rotor design:
1. Fixed-angle centrifuges are designed to hold the sample containers at a constant angle relative to the central axis.
2. Swinging head (or swinging bucket) centrifuges, in contrast to fixed-angle centrifuges, have a hinge where the sample containers are attached to the central rotor. This allows the samples to swing outwards as the centrifuge is spun.
3. Continuous tubular centrifuges don’t have individual sample vessels and are used for high volume applications.

centrifugal force causes the material to separate

Decanter centrifuges are used to extract (dewater) solid materials from liquids when they are mixed together in slurry. Decanter centrifuge is used in many industrial applications such as:Oil /solids separation ,Industrial and biological wastewater treatment, food processing,Fish processing, Chemical slurry.

A main drive motor supplies power to turn the centrifuge. AC drives are commonly used to power the main drive motor. There are several different types of decanter centrifuges, such as: Vertical, horizontal, or scroll (conveyor).

Decanter centrifuge design consists of a solid container, called a bowl, which rotates at high speed. Inside the bowl tube, a screen conveyor rotates in the same direction, but at a slightly different speed. A differential gear is typically used to adjust speed.

Decanter centrifuges are used to extract solid materials

1. The decanter centrifuge slurry is fed through a stationary pipe, which is inside a hollow shaft connected to a screw conveyor or scroll.
2. The slurry enters a feed compartment located inside of the conveyor and is forced through discharge nozzles to the bowl section.
3. Once inside the bowl, centrifugal force causes the material to separate.
4. The screw conveyor moves the solids to the tapered end where they are discharged.
5. Clear fluid flows out the other end.

This type of centrifuge is common in the wastewater treatment plants. It is considered a continuous flow machine because it will run hours at a time.

Some decanter centrifuges are powered by a motor and gearbox combination. The gearbox provided the correct speed and torque to drive the solid control centrifuge. Since this is a mechanical type of configuration, it is subject to frequent preventive maintenance and mechanical failures. An AC drive can provide the required torque with greater efficiency and reliability.

What is the application of centrifugal pump

What is a centrifugal pump? Centrifugal pumps are a popular choice for low viscosity (thin) liquids that need to be pumped at high flow rates. Centrifugal pumps are often used in many industrial, municipal and commercial applications and are usually quick to install and easy to repair.

Centrifugal pumps use one or more impellers that rotate on a shaft. The rotating impeller moves the fluid along the spinning vanes, which increases the velocity of the fluid. The fluid then leaves the impeller vanes and moves into the pump volute where the velocity of the fluid is converted into high pressure through a diffusion process. Then the fluid is sent through the discharge port of the centrifugal pump and into the piping system.
There are dozens of centrifugal pump types available, including: end suction pumps, booster pumps, regenerative turbine pumps, fire pumps, grinder pumps, jet pumps, mag drive pumps, submersible pumps, trash pumps and many more.

Centrifugal pump is a subclass of turbomachinery technology

Centrifugal pump is a subclass of turbomachinery technology. The main work of this type of pump is to bring up fluids through the transformation of the rotational energy into another energy called hydrodynamic energy. Typically, the rotational energy source is either the turbine, electric motor or engine. 

The term centrifugal force pertains description of the movement of energy that is from the impeller's mechanical rotational phase to the fluid's pressure and motion. However, the term centrifugal force is not always required to be used in describing the working mechanism of a particular centrifugal pump. Much like the other pumps, centrifugal pumps are indeed useful despite some criticisms and controversies. 

The cantilever pumps or vertical centrifugal pumps are likewise known in many industries. The main feature of this quality pump is the utilization of a special type of shaft and bearing configuration which permit the hanging up of volute just in the sump. Also, this pump model uses throttle bushing, instead of stuffing box in sealing the shaft. In most "parts washer," cantilever pumps are often used. 

Also, the forth pumps are widely used in oil and mineral industries. The issue concerning the use of this type of pump has something to do with the air content of froth, which blocks conventional pumping force. This problem was vigorously addressed by the oil industry through different approaches. The first approach involved the use of vertical pump with a built-in tank; the second approach involved the creation of a pump that has a built-in impeller capable of tearing air bubbles into pieces. 

Looking at the paper and pulp industry, holes are mainly done on the pump's impeller. The mechanism is simple: While the air goes out at the rear side of the impeller, an expeller discharges it back to the pump's suction tank. The vanes--either secondary vanes or split vanes--may be incorporated in the impeller. 

Regarding the mechanism of a multi-stage centrifugal pump, usually the impellers are mounted either on different shafts or on a single shaft. It is called multi-stage simply because the device has more than one impellers. In addition, for the device to produce higher rate of flow output, the impellers may be adjoined in a parallel manner; and to generate higher level of pressure at the device' outlet, the impellers may be adjoined in series. Often, multi-stage centrifugal pumps are used in boiler feed-water pumps and other similar pumping needs.
