All types of Compressors & Spares

Types of Compressors

1. Reciprocating Compressors

• Function: Use pistons driven by a crankshaft to deliver gases at high pressure.
• Applications: Industrial plants, gas pipelines, refrigeration, air conditioning.

2. Rotary Screw Compressors

• Function: Use two meshing helical screws to compress the gas.
• Applications: Continuous operation in manufacturing, automotive, and other industries.

3. Centrifugal Compressors

• Function: Use a rotating impeller to add velocity to the gas and convert it to pressure.
• Applications: Large-scale industrial applications, HVAC systems, gas turbines.

4. Axial Compressors

• Function: Use a series of rotor and stator stages to progressively compress the gas.
• Applications: Aircraft engines, large industrial plants.

5. Scroll Compressors

• Function: Use two interleaved spiral scrolls to compress the gas.
• Applications: Air conditioning, refrigeration, and small-scale industrial applications.

6. Rotary Vane Compressors

• Function: Use a rotor with vanes that slide in and out to compress the gas.
• Applications: Medium-duty industrial applications, automotive industry.

Common Spare Parts for Compressors

1. Reciprocating Compressors

• Pistons and Rings: Essential for the compression process.
• Crankshaft: Converts rotational motion into reciprocating motion.
• Valves: Control the intake and discharge of gas.
• Bearings: Support rotating parts and reduce friction.
• Gaskets and Seals: Prevent leaks and maintain pressure.
• Connecting Rods: Transfer motion from the crankshaft to the pistons.
• Cylinders: House the pistons and maintain the path for gas compression.

2. Rotary Screw Compressors

• Screw Elements: The main components that compress the gas.
• Bearings: Ensure smooth rotation of the screws.
• Seals: Prevent oil and air leaks.
• Oil Filters: Maintain the quality of lubrication oil.
