Air Compressors

Piston Compressors Overview

The piston compressor is a type of displacement compressor that is one of the oldest industrial compressor types in the market. Most industries utilizing piston compressors use them because of their performance, affordability, and easier functionality. The piston compressors use displacement as a basic working principle, but there’s more to these compressors that you should learn. The piston compressors are now available in various designs to meet industry requirements accordingly. The system usually has low-pressure and high-pressure cylinder systems that compresses the air inside for air-operated tools.

Piston Compressors: Understanding the Working

The piston compressors use a valve system consisting of two valve disks and the standard air drawing method. The piston moves downward, allowing air to enter the system. The atmosphere makes the largest disk flex in the arrangement and folds downward, allowing more air to pass through. The large disk moves again, which seals the valve seat. The compressed air forces through the hole in the valve seat and reaches the end process location. Thus, it is safe to say that piston compressors are a positive displacement air pump that operates using crankshaft via cylinders and pistons. Air compression reduces the volume of air present inside, building pressure and density, without altering its state of matter.

Here’s a step-by-step breakdown of the process for better understanding.

  1. The air/gas enters the piston compressor through the intake valve.
  2. The piston moves from its resting position, allowing the gas/air to pass into the cylinders.
  3. The compressor pump gathers power from the crankshaft, comping the air with a single power stroke.
  4. With the two-stage piston compressors, the gas reaches the second cylinder using an additional power stroke. The second stroke provides a power stroke option of 175 psi.
  5. The compressed air finally reaches the storage tank for use.

Thus, the working of the piston compressors is simple yet functional.

What can you use Piston Compressors for?

The piston compressors are positive displacement pumps, best for industrial applications. They use a reciprocating mechanism, allowing two or more pistons to compress air. Once the gas compresses, it forces the valves to collect the gas for use. The versatile use of these compressors makes them ideal for heavy-duty or industrial tasks.

Refrigeration Cycle

The piston compressors assist in the refrigeration process due to their efficiency. It helps compress and propagate the compressed coolant through the system to maintain temperatures.

Oil Refineries

Oil refries process viscous liquids such as crude oil through air-operated tools. The air operated-tools require a balanced air supply that piston compression systems can easily supply to the users.  

Gas Pipes

The piston compression pumps are also suitable for gas pipes, especially for natural gas processing systems. It helps blow consistent pressure into the system, which is why professionals utilize it in chemical plants too. For example, chemical plants may use it in complicated techniques such as the Haber-Bosh Process.

Bottom Line

Investing in a piston compressor can make it easier for industrial units to get affordable and consistent performance. The piston compressor is a positive displacement pump, allowing superior air pressure production and storage. The piston compressors are especially good since they require less lower maintenance.
