Reciprocating compressor

Device used to pump gases at high pressure

For more detailed information, please visit our website SUNCENTER.

A reciprocating compressor or piston compressor is a type of positive-displacement compressor that utilizes pistons operated by a crankshaft to compress gases at high pressures. These compressors are capable of generating pressures up to 5,000 psig, typical for multistage units.

The process begins with gas entering the suction manifold, subsequently flowing into the compression cylinder. Here, the gas is compressed by a piston that moves in a reciprocating fashion, powered by a crankshaft, before it is discharged. They are widely used across various industries, including railway and road vehicle air brake systems, oil refineries, gas pipelines, oil and gas production, air and nitrogen injection, offshore platforms, chemical plants, and even for refrigeration and air conditioning. One specialized application includes the blowing of plastic bottles made from polyethylene terephthalate (PET).

Recent innovations like the ionic liquid piston compressor have eliminated many seals and bearings, as the ionic liquid does not mix with the gas. This design approach offers a service life that is about ten times longer than conventional diaphragm compressors, along with significant maintenance reductions and up to 20% lower energy costs. Furthermore, traditional heat exchangers are omitted since heat is managed within the cylinder itself, ensuring that nearly all energy input into the process is effectively utilized with minimal waste as reject heat.

Reciprocating compressors are notable for their exceptionally high maximum discharge pressures. When considering a purchase, you should reflect on several key factors:

• Is the output air required to be clean, dry, or free from oil?
• What is the expected operating time for the compressor annually?
• Will the compressor be in continuous use throughout the day, or will it have shifts?
• Is there fluctuating demand for compressed air during daily operations?
• Are there plans for expansion that may alter future requirements?

The decision-maker for the purchase can also significantly influence the selection process.

Engineers often make choices that benefit the overall project rather than focusing solely on the compressor's specific application, influenced by technical, commercial, scheduling factors, along with future expectations.

Several non-technical considerations must also be acknowledged:

• Operating conditions (both current and anticipated)
• Brand quality and reputation
• Availability of skilled maintenance personnel
• Staff familiarity with the equipment
• Possibility for automation and digital controls
• Access to replacement parts
• Delivery timelines
• Purchase price and total life-cycle cost

The choice of the right reciprocating compressor is indeed multifaceted.

Understanding your precise requirements or identifying inefficiencies is the first crucial step.
