WELCOME

FRICTIONLESS COMPRESSOR TECHNOLOGY GUIDED BY Mr HARISANKAR ASSISTANT PROFESSOR DEPT OF MECHANICAL RIET

PRESENTED BY VISHNU VIJAYAN REG NO:-12428066 DEPT OF MECHANICAL RIET

INTRODUCTION • Compressor is a device used for creating high pressure. • Conventional type of compressor works with roller bearing and hydrodynamic bearing • Therefore they require lubrication • The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor • Permanent magnet brushless synchronous motor has permanent magnet instead of copper windings.

HOW ARE THEY DIFFERENT? They Are Different because:* Magnetic bearings. * Oil-free design. * VFD control. * Smaller and lighter than conventional compressors.

MAGNETIC BEARINGS • No friction. This can improve energy efficiency by 2-4%. • Run at high speeds (up to 48,000 RPM) and give good speed control. • Magnetic-bearing compressors offer economic, energy and environmental benefits.

OIL FREE DESIGN • The biggest benefit to eliminating oil from the system is that it eliminates the need for a lubrication system. • It reduces the maintenance cost of compressor by 50 percent

VFD CONTROL • Variable Frequency Drive provides good speed control, allowing the system to run up to 48,000 RPM.

SMALLER AND LIGHTER • Using permanent magnets will reduces the weight and size. • They are one-fifth of the weight and half the size of an equivalent conventional compressor.

ADVANTAGES • Reduced maintenance costs. • Easier and quicker installation. • Sound level less than 70 decibel(dB).

DISADVANTAGE • Price is 50-70% more than normal Compressor. • Power of permanent magnet will decrease.

CONCLUSION • Magnetic-bearing compressors offer economic, energy, and environmental benefits. • Chief among them are increased energy efficiency, the elimination of oil and oil management, and • Considerably less weight, noise, and vibration.
