There can be many types of compressor systems, and they are used in various fields of work. One of them is the liquid ring compressor system that belongs to the family of the positive displacement compressors. Replacing the metallic pistons, this type of compressors uses a fluid that is centrifuged in the main casing that has a specific shape. The fluid that is used in a liquid compressor can be anything such as water, acids, crude oil, gasoline, etc. Be it any fluid but the only thing that has to be taken care of is that the fluid should not react with the gas which needs to be compressed.
Theoretically, this type of compressors are maintenance free, and therefore the metallic parts do not wear and tear rapidly, and hence the efficiency of the liquid ring compressor system is enhanced to a great extent when compared with other types of compressor systems.
The Usage
If one is wondering as to where these types of compressors are used, well the answer is that they can and are generally used in diverse industrial processes. And these include the fermenting industry, the place where agitating tanks for liquids are needed, for feeding gas or air to the burners, the aerating tanks used in the process of fermentation or to compress the gas or air for use in a variety of activates that requires high speed and pressure of the flow. They are also used in operations where drying and vacuum are needed.
The Working Principle
The casing of the liquid ring compressor system is filled with the required fluid, and it is known as the seal fluid. The liquid is filled up to the level of the rotor centerline. The process gas is allowed to enter the compressor through the conical distributor fixed on the front cover of the compressor unit. When the compressor starts the fluid or the seal liquid is centrifuged by the impeller rotation inside the compressor. There are two discharge and two suction ports in the conical distributor each aligned in the opposite direction.
During the first phase of rotation, gas is sucked into both chambers inside the casing and in the next phase; the gas gets compressed and is pushed out of the discharge port. This action continues with the third, and the fourth phases of rotation and the radial forces that originate due to the rotation of the impeller and the compression of the gas due to suction and discharge allow the liquid ring compressor system to work in a balanced manner.
The Advantages Of Using Liquid Ring Compressor System
The liquid ring compressor system has many benefits. They are built with the best technology that can produce a steady flow of gas with a minimum fall in the pressure. It functions smoothly without any glitches and making any noise.
The liquid ring compressor system is very compact in design and the capacity to weight ratio is evenly balanced. They are lightweight and easy to move from one place to another. The working of the compressor is unique as the full load, and part load performances are proportionate and reasonably good when compared with other types of compressors. The maintenance of these compressors is quite effortless as they are typically designed with the back pullout system.
Conclusion
With so many advantages over other types of compressors and a proven working principle, liquid ring compressor system is being adopted by many industries, and their popularity is increasing day by day. One should always stay updated using new technology to get better performance on the shop floor.
