Mobile applications have three basic styles of compressors. These are:
- Reciprocating Compressors
- Rotary Screw Compressors
- Rotary Vane Compressors
A reciprocating or piston ring compressor is classified as a positive-displacement compressor. Its name is derived from the operation of its mechanicals. A crankshaft drives the pistons to deliver gases at high-pressure levels.
Among the different types of industrial compressors, the piston is the oldest. It is also the most common. Like other types, the piston ring compressors are available in diverse kinds. They are single or double-acting. They are oil-free or oil-lubricated. The oil-free variation usually possesses rings made from carbon or polytetrafluoroethylene (PTFE).
Piston Ring Compressors feature a different number of cylinders arranged in diverse configurations. However, in most cases, small compressors are found in V configurations while larger, double-acting ones generally have an L-configuration.
Benefits of Piston or Reciprocating Compressors
In mobile applications, it is more likely to find a reciprocating compressor over the other two major types. The reasons for installing one vary but are generally based on the following perceived benefits:
- Cost: Of the three types listed above, the reciprocating compressor is the least expensive
- Functionality: A piston ring compressor is able to produce both high power and high pressure as well as provide a continuous flow
- Maintenance and repair on site: The simplicity of the design of a piston compressor allows for easy and fast repair and/or facile rebuild in the field using only the most basic hand tools
These are some of the reasons they are very popular among the oil and gas industry.
Piston Ring Compressor
Reciprocating or piston ring compressors are among the oldest types used for industrial applications. They remain popular because of their low initial cost, simplicity, and functionality. While other types of compressors are available, the piston ring compressor is still favored for use in gas pipelines and oil refineries.
