How does Decanter Centrifuge Work?

Decanter Centrifuge

Introduction: Decanter centrifuge is a very common equipment that is often found in an oil or gas drilling site. A decanter centrifuge is a very important machine for oil and gas drillers. A decanter centrifuge is basically used to dilute the underground fluids and liquids.

The main job of a decanter centrifuge is to rotate the drilling fluids and in doing so breaking the concentration of those fluids. The whole working functions of any decanter centrifuges is pretty much complex. Here is a discussion given below about how a decanter centrifuge works.

The way a decanter centrifuge works:  As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually,  decanter centrifuges depend on sedimentation, differential speed and G force to perform its job. A decanter centrifuge needs a centrifugal force in order to loosen the fluid.

The sedimentation rate is an important feature for the centrifugal process. If the G force or centrifugal force is very high, the separation process becomes very easy and effective. The size and shape of particles and their level of concentration determine the sedimentation rate of any decanter centrifuge.

The sedimentation rate also depends on the centrifugal force. Another important issue for the functionality of decanter centrifuges is the differential speeds. In a centrifuge two different parts rotate simultaneously. The first part that rotates is the exterior bowl and the second part that rotates is scroll conveyor. Sedimentation is gathered in the centrifugal cylinder as the result of varying speed of the two above mentioned separate parts.

If the differential speed of decanter centrifuges is too high, a little time is required to loosen up the concentration of waste fluids. So, it is very important to keep the differential speed of a decanter centrifuge minimal. Thus, a decanter centrifuge operates its functionalities.

Decanter Centrifuge Defined Meaning

Introduction: Modern gas and oil drilling sites are just a rigid manifestation of multi layered complex mechanism. Several gigantic equipments are set and operated in a single oil or gas drilling sites. The mechanisms of these equipments are very complex and very subtle. A very common equipment that is seen in an oil and gas drilling site is a decanter centrifuge.

A decanter centrifuge is a very useful equipment for any drilling site. Here in this article, we will try to provide a brief description about what a  really it is.

A brief description of a decanter centrifuges: A decanter centrifuge is a device that can create a very fast rotation that is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible. In order to thin up the extracted fluids, a decanter centrifuge is used. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid.

There are three basic designs of decanter centrifuges:

The first one is vertically oriented decanter centrifuges.
The second one is horizontally oriented decanter centrifuges.
The third one is conveyor or scroll decanter centrifuges.

In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically. Vertical decanter centrifuges are very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuges gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.

Operation and Maintenance of Decanter Centrifuges

Decanter Centrifuge

Introduction: A decanter centrifuge is very important machine for any oil or gas drillers. It enables them to perform drilling activities in a certain site. So, the operation and maintenance of a decanter centrifuge is a major issue for any drilling companies. In order to get the most of the benefit from a decanter centrifuge,   it should be maintained and operated well. Here is a brief discussion about how decanter centrifuges should be operated and maintained.

The operating and maintaining process of a decanter centrifuge: The first thing that should be done to maintain a decanter centrifuge is to replace any hydraulic suction filter and replace hydraulic returns filter. It is a very important step for the oil and gas drillers. As when the oil or gas drilling goes on both the hydraulic suction filter and the hydraulic returns filter undergo an extensive pressure.  So, there is a huge possibility of both of them to be worn out. So in that sense, both of the filters must be checked regularly and be replaced when it is necessary. Another important thing that is required to do in order to maintain a decanter centrifuge is greasing the machine.

It is very important. As decanter centrifuge is basically used in a heavy working areas, the machine can easily be stuck or jammed off. In order to avoid that, greasing is very important. Oil lubricated gear box greasing and recirculating oil greasing are two very effective methods for greasing. A very significant task for managing decanter centrifuges are adjusting speed sensor to it. It is very important just because adjusting a speed sensor enables drillers to control the differential speed. Beside these above mentioned activities replacing hydraulic motor sensor, bowl belt replacement, scroll belt replacement and regulating the weir plate are some of the steps that should be taken to maintain a decanter centrifuge.
