Crucial Air Compressor Parts That Impact Performance

Air compressors used in industrial processes such as petrochemical, gas, or chemical units are made up of several components. Each part strives to offer a degree of support to the machine. Reciprocating or piston air compressors can reach high PSI levels, and this feature makes reciprocating air compressors a valuable manufacturing tool. 

The air compressor parts play a vital role in managing heat, helping in rotational activities, boosting the machine's durability, minimizing gas flow, etc. However, each of the components differs from the other, and listed below are some crucial parts that need to work efficiently to guarantee zero downtimes and optimal daily performance.

Key Parts of Reciprocating Air Compressors

  • Frame: This is the house of the entire machine. The frame often has a square or rectangular shape. Most air compressor frames rarely receive any performance-degrading damage as they offer support to the crankshaft.
  • Distance Piece: This part separates the compressor cylinder of the frame. It can have a single, double, or extended compartment to let pistons enter the frame with proper spacing. Distance piece is classified into type A, type B, type C, and type D.
  • Cylinders: Cylinders are an essential part of a reciprocating air compressor's air chambers. Cylinders reduce the working temperature by removing hot air through cool air in-flow using its fins.
  • Piston: Pistons are significant air compressor parts that must have enough strength and weight and be compatible with compressing the gas. Most pistons use aluminum or cast iron. Its force and power provide air compressors with air pressure, and its movement brings about the compression and suction of the refrigerant.
  • Piston Rings: These come in contact with a cylinder's walls to ensure it passes all air within its chamber. Piston rings are smooth enough to pass through cylinder chambers. However, operators always have replacements handy because of their rapid wear and tear.
  • Crankshaft: The crankshaft is the primary driver of the piston, piston rod, and connecting rod as the shaft revolves around the frame axis. Most air compressors use motorized crankshafts. AC-powered air compressors connect directly to the crankshaft. Alternatively, some electric motors can use a belt and pulley connective system.
  • Crosshead: A crosshead allows pistons to insert into the cylinder bore. This is one of those air compressor parts that enable a compressor to have longer strokes by using a narrow piston and generate higher efficiency.
  • Connecting Rod: This is the link between a piston and a crankshaft. This rod is required to promote the rotary motion of the crankshaft and also helps the translation of the piston within the cylinder.
  • Bearings: You can find these in different areas of the air compressor. These air compressor parts can be found throughout their frame. They help ensure that all air compressor components are accurately positioned axially and radially.
  • Valve: A valve controls airflow inside an air compressor. Most air compressors are placed at each operating end of a cylinder, and they use either a ring, poppet, or a plate-type valve.
