A reciprocating compressor is a positive-displacement machine that increases the pressure of a gas by reducing its volume. It is an active mechanical device that compresses the gas by doing work on it. It consists of a cylinder, piston, connecting rods, and a crankshaft. The cylinder contains the gas, and the piston compresses it as it moves back and forth inside the cylinder.
The main purpose of a reciprocating compressor is to compress a gas from a lower pressure to higher pressure. They are widely used in a variety of industries, including air conditioning, refrigeration, and petroleum processing. Power generated from reciprocating compressors is often used to achieve a desired temperature and pressure for a given space.
Reciprocating compressors are relatively simple in operation and design and are less expensive than other types of compressors. They are also commonly used in fuel gases and toxic gases due to their robust design and low maintenance and environmental footprint.
Unlike centrifugal compressors, which rely heavily on rotating mechanical parts, most reciprocating compressors require minimal maintenance because they have fewer moving parts and no rotating components. The only wear-and-tear parts are the piston seals and crankshaft bearing, which need to be periodically checked and replaced. This preventive maintenance, along with proper lubrication, will ensure the compressor has a longer life and safer, more reliable performance.
A reciprocating compressor is an ideal choice for applications that require a high level of flow capacity for a given pressure ratio. Examples include apropane compressor for a pressure washer, an air compressor for a nail gun, or a gas booster compressor for a gas turbine.
Reciprocating compressors also have higher efficiency than rotary compressors, making them a more cost-effective choice for many industries. Additionally, because the flow rate is relatively constant and the pressure ratios are low, their capital costs are also low.
In summary, a reciprocating compressor is an ideal choice for many industries due to its low cost and high efficiency. Their compact size and minimal maintenance requirements also make them attractive for many applications. For larger applications, they are an ideal choice because they can reach higher compression ratios with fewer rotating parts.
