What is compressor and its types PDF?
The two most common types of compressors are positive displacement and dynamic. Positive displacement compressors use screws, sliding vanes, lobes, gears, or pistons for compression. Positive displacement compressors include reciprocating and rotary compressors.
What is application of compressor?
Compressors are used throughout industry to provide shop or instrument air; to power air tools, paint sprayers, and abrasive blast equipment; to phase shift refrigerants for air conditioning and refrigeration; to propel gas through pipelines; etc.
What is main component in compressor?
The basic components of the air compressor are the electric motor, pump, and receiver. The receivers can be vertical or horizontal and have different size and capacity. An electric Motor powers the compressor pump.
What are parts of a compressors?
- Cylinder Head,
- Suction/ Intake valve,
- Delivery valve,
- Cylinder liner/ Wall/ cooling water jacket,
- Compressor casing,
- Crank case,
- Connecting rod,
What is compressor efficiency?
The compression efficiency is the ratio of the work required to adiabatically compress a gas to the work actually done within the compressor cylinder as shown by indicator cards (Figures 18-12 and 18-16). The heat generated during compression adds to the work that must be done in the cylinder.
What is compressor capacity?
Capacity is the quantity of air at which the compressor will operate at a specific discharge pressure. For all industrial compressors, capacity is rated at the conditions of pressure, temperature and moisture content existing at the compressor inlet flange.
Does temperature change in a compressor?
Pressure multiplied by volume divided by temperature equals a constant. The combination law explains what happens to air when it’s compressed into a smaller volume. It tells us that when air is compressed, the pressure and temperature of the air increases, as the volume of the space containing air decreases.
What is the unit of compressor?
The power of a compressor is measured in HP (horsepower) and CFM (cubic feet per minute of intake air).
What are the principles on which compressors work?
By- AdityA ShArmABy- AdityA ShArmA 2. Principles on which compressors work: A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
What are the factors affecting the performance of a compressor?
FACTORS AFFECTING COMPRESSOR PERFORMANCE 7.1 Inlet air temperature 7.2 Dust inlet in air 7.3 Dryness of inlet air 7.4 Altitude/elevation 7.5 Performance of inter-stage & after coolers 7.6 Delivery pressure setting 7.7 Pressure drop in flow through pipes 7.8 Bends & fitting losses 88
How do air compressors work?
10. 1.3 Compressors and their working principle An air compressor is basically a device that converts power (usually from an electric motor, a diesel engine or a gasoline engine) into kinetic energy by compressing and pressurizing air. This compressed air can be stored, or can be released in quick bursts, on command.
What are the characteristics of reciprocating compressor?
4. In a reciprocating compressor, a volume of gas is drawn into a cylinder, it is trapped, and compressed by piston and then discharged into the discharge line. The cylinder valves control the flow of gas through the cylinder; these valves act as check valves. Reciprocating compressors can be Single acting or double acting.
