Reciprocating Compressors Manufacture in Coimbatore

A reciprocating air compressor is a positive-displacement machine that uses a piston to compress a gas and deliver it at high pressure.
They are often some of the most critical and expensive systems at a production facility, and deserve special attention. Gas transmission pipelines, petrochemical plants, refineries and many other industries all depend on this type of equipment.
Various compressors are found in almost every industrial facility. Types of gases compressed include the following:
1.Air for compressed tool and instrument air systems
2.Hydrogen, oxygen, etc. for chemical processing
3.Light hydrocarbon fractions in refining
4.Various gases for storage or transmission
5.Other applications
There are two primary classifications of industrial compressors: intermittent flow (positive displacement), including reciprocating and rotary types; and continuous flow, including centrifugal and axial flow types.
Reciprocating compressors are typically used where high compression ratios (ratio of discharge to suction pressures) are required per stage without high flow rates, and the process fluid is relatively dry.
Wet gas compressors tend to be centrifugal types. High flow, low compression ratio applications are best served by axial flow compressors. Rotary types are primarily specified in compressed air applications, though other types of compressors are also found in air service.
A piston is driven in a reciprocating action to compress the gas. Arrangements may be of single-or dual-acting design. (In the dual-acting design, compression occurs on both sides of the piston during both the advancing and retreating stroke.)
Some dual-acting cylinders in high-pressure applications will have a piston rod on both sides of the piston to provide equal surface area and balance loads. Tandem cylinder arrangements help minimize dynamic loads by locating cylinders in pairs, connected to a common crankshaft, so that the movements of the pistons oppose each other.
Gas pressure is sealed and wear of expensive components is minimized through the use of disposable piston rings and rider bands respectively. These are formed from comparatively soft metals relative to piston and cylinder/liner metallurgy or materials such as polytetrafluoroethylene (PTFE).
