3. INTRODUCTION A Compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Vane compressor is positive displacement rotary type compressor. It used in multi level industrial applications . Figure 01 : Types of Compressors

4. Vane Compressor is also known as Rotary Vane Compressor or Sliding Vane compressor. Vane Compressor was invented by Charles C. Barnes of Canada. He patented it on 16 June 1874 . These vanes are made of steel or synthetic fibrous material. If the compressor is oil-lubricated, there will be a thin layer of oil in between the vane and housing. High pressure ratio requires large number of vanes ( 20 – 30 ). For a given pressure ratio, cane compressor requires less work input than that for roots blower.

5. This is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. The rotor is positioned eccentrically within a cylindrical housing. The vane-type compressor consists of a cylindrical rotor with longitudinal slots in which radial sliding vanes are fitted. The spaces between adjacent vanes form pockets of decreasing volume from a fixed inlet port to a fixed discharge port. Larger the number of vanes smaller the leakage of air due to small pressure difference prevailing between the adjacent spaces around the rotor.

6. Air is drawn in through the intake valve. Air is contained between the rotor and casing. Air is compressed by decreasing volume. Lubricant is continually injected to cool, seal and lubricate. Compressed Air moves to the Outlet and vanes were released. The rotor continuously rotate and Produce high Pressure Air. OPERATION METHOD Most of the modern compressors has Air filter system and cooling system for vane compressor. Figure 05 : Basic Structure of Vane compressor

7. Operation Method…

8. They are used in agriculture for operating farm equipment, material conveying, etc. Used in the auto body paint shop for paint pump operation. Used in tire and wheel shop for tire inflation. Used in dry cleaning. Used in the operation of air knives for cutting and peeling. It is used in welding operations and air-operated metal and wood working tools. APPLICATIONS Figure 06 : Application of Vane compressor Figure 07 : Application of Vane compressor

9. It creates a good vacuum for suction. Vane Compressor works well for continuous air supplied. High pressure and high-power compression are possible with vane compressor. Vane compressors have a longer life expectancy. They are ideally suited for moderate pressure using applications.

10. The vibration happens during the reciprocation of the cylinder. Because of more number of moving parts maintenance cost is high. DISADVANTAGES Figure 13 : Vibration monitor report of Vane compressor Figure 14 : Maintenance of Vane compressor
