air compressor types slideshare

PRESENATION ON…. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Types of rotary compressor: Screw compressors, Vane type compressors, Lobe and scroll compressors and other types. They take advantage of the principle of positive displacement. 8 Screw compressor • Rotors instead of pistons: continuous discharge • Benefits: low cost, compact, low weight, easy to maintain • Sizes between 30 – 200 hp • Types • Lobe compressor • Screw compressor • Rotary vane / Slide vane Rotary Compressor Types of Compressors 9. Its function is to cool and lubricate the compressor element's moving parts, to cool the air being compressed internally, and to reduce the return leakage to the inlet. The air is then compressed as the piston moves upwards. See our Privacy Policy and User Agreement for details. Compressors may be characterized in several different ways, but are commonly divided into types based on the functional method used to generate the compressed air or gas. You can change your ad preferences anytime. The engineering unit may be small or big, everyone uses an air compressor to perform various tasks as per the requirement.. For different kind of requirements, different types of the compressor have to be used..

The most common rotary air compressor is the single stage helical or spiral lobe oil flooded screw air compressor. An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. single stage air compressor :When the piston moves down inside the cylinder, the air enters the space above thanks to the difference between the atmospheric pr… 4 Primary Types of Rotary Compressors: Rotary Screw Sliding Vane Lobe Centrifugal Axial flow 21. 1. Compressors supply the air flow for all equipment in a system. TYPES OF AIR By Pramod A. Before tackling air compressor troubleshooting or maintenance, you need to first understand the air compressor basics in this tutorial. – Type : • Variable intake guide vanes • Variable stator vanes • Compressor bleed valve 18. two stage air compressor : Two-stage compressors take the air in from the atmosphere just like single-stage units, but as you can see on the picture they have two cylinders instead of one. See our Privacy Policy and User Agreement for details. A rotary-screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism.They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications such as chillers, or to operate high-power air tools such as jackhammers and impact wrenches. Air compressors work in two phases: the compression operation and the release operation. ... slide out by centrifugal force until they seal against a thin film of lubricant coating the stator wall. See our User Agreement and Privacy Policy. In liquid-injected screw compressors, a liquid is injected into the compression chamber and often into the compressor bearings. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. multi stage air compressor :The intake of air in the first stage gets compressed and then it is passed over a cooler to achieve a temperature very close to ambient air.

With the right air tools, you can accomplish a lot just with a standard compressor. TYPES OF COMPRESSORS 2.1 Classification basis • 2.1.1 Positive displacement compressors o Reciprocating compressors o Rotary compressors • 2.1.2 Dynamic compressors o Centrifugal compressors o Axial compressors 2.2 Selection criteria for compressors 2.3 Comparison of compressors … A vent or valve to release pressure or to allow air to move freely around something. See our User Agreement and Privacy Policy. Introduction • The machine which takes in air or any other gas at low pressure and compresses it to high pressure are called compressors. Positive displacement compressors cab be further divided into Reciprocating and rotary compressors. Reciprocating Compressor has piston, cylinder, inlet valve, exit valve, connecting rod, crank, piston pin, crank pin and crank shaft. .AIR COMPRESSOR. piston air compressor and rotary screw air compressor. into potential energy stored in pressurized air (i.e., compressed air).By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. COMPRESSOR Besides inflating tires, cleaning, and painting, drilling, air compressors are capable of doing so much more. Rotary air compressors are positive displacement compressors.
