Structure
Distance pieces are components in air compressors that serve as spacers between various parts of the compressor, often separating the crankcase from the compression cylinder. These pieces play a crucial role in ensuring the proper alignment and spacing of the compressor's internal components, thereby maintaining the efficiency and integrity of the machine.

Material
Distance pieces are typically made from robust materials that can withstand high pressures and temperatures, such as:
Steel: Known for its strength and durability.
Aluminum: Offers good strength-to-weight ratio and resistance to corrosion.
Cast Iron: Provides excellent wear resistance and strength.
The choice of material depends on the specific application and operating conditions of the air compressor.
Applications
Distance pieces are used in various types of air compressors, including:
Reciprocating Compressors:
Separates the crankcase from the compression cylinder.
Prevents oil contamination in the compression chamber by providing a barrier.
Rotary Compressors:
Ensures proper alignment and spacing between rotating elements and stationary components.
Centrifugal Compressors:
Used to align the stages of the compressor and maintain the structural integrity of the assembly.
Specific Uses
Oil-Free Compressors: Distance pieces are essential in oil-free compressors to ensure that the oil used in the crankcase does not reach the compression chamber, which is critical for applications requiring contaminant-free air.
High-Pressure Compressors: In high-pressure applications, distance pieces help manage the high stress and strain on the compressor's internal components by providing a stable structure.
Industrial Applications: Used in compressors for manufacturing, automotive, and aerospace industries where precise and reliable air compression is necessary.
Summary
Distance pieces in air compressors are vital for maintaining proper spacing, alignment, and separation of various internal components. Constructed from materials like steel, aluminum, and cast iron, these pieces are designed to endure high pressures and temperatures. Their applications span across various types of compressors, ensuring efficient and reliable operation in industrial, automotive, and aerospace applications.
