Frictionless Compressor Published on Jan 10, References 24 25 26 10 9 1. With the help of digital control system the controlling and monitoring of work is very easy. Within the compressor, efficienc is affected by the y Compressor isentropic efficienc the efficienc of the wheels the motor, and the bearings. The stator windings found conventional induction motors are replaced with a permanent-magnet rotor.
Often, one of the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid or gas between the scrolls.
Important status and control information is available at a glance or a touch. The motor and key electronic components are internally refrigerant cooled, so no specialcooling is required for the VFD or the motor. With the help of digital control system the controlling and monitoring of work is very easy.
They are used where there is a requirement for a high flows or a compact design. The variable-speed centrifugal compression and digital electronic technologies enables the frictionless compressors nominal ton capacity range to achieve the highest compressor efficiencies, cost effectively, for middle-market, water-cooled, evaporative cooled and air-cooled HVACR applications.
Low maintenance costs as there are no wearing parts. Compressors that require higher shaft speeds tend to use gears.
Choose Type of service. Types of compressors 1. If you need this or any other sample, we can send it to you via email. The convergence of aerospace and industrially proven magnetic bearings, variable-speed centrifugal compression and digital electronic technologies enables the frictionless compressors nominal ton capacity range to achieve the highest firctionless efficiencies, cost effectively, for middle-market, water-cooled, vaporativecooled technollogy air-cooled HVACR applications.
While gears are a proven technology, they create noise and vibration, consume power, and require lubrication. Their application can be from 3 hp 2.
With suitable port connections, the devices may be either a compressor or a vacuum pump. This article describes this new compressor technology and its first use in an ARI-certified chiller design. It rotates on a levitated magnetic cushion Figure 1. Learn how your comment data is compressr. Soft start and Ramp up.
With the help of digital control system the controlling and monitoring of work is very easy. In fact, the only required regular maintenance of the compressor is the quarterly tightening of the terminal screws, the annual blowing off of dust and cleaning of the boards, and the changing of the capacitors every five years.

Many large snow-making operations like ski resorts use froctionless type of compressor. Beyond about 5 stages or a 4: Haven’t found the Essay Seminag Want? This is initial mid-range package offers centrifugal compression efficiencies previously reserved for large tonnage systems only. Department of Mechanical Engineering for their valuable advices at crucial times.

Application 1 Water-cooled chiller applications 2 Rooftop and packaged system applications 3 Air-cooled chiller applications 4 Multiple compressor applications References 1.
It can use the same power wiring with a single control. Dry vane machines are used at relatively low pressures e. A ll IPLVs are weighted for standard operating conditions and fricfionless time spent at those conditions.
Seminar On Frictionless Compressor Technology- Mechanical Seminar Topic
Magnetic bearings eliminate the need for these systems hechnology oil management in general. Chief among them are increased energy efficiency, the elimination of oil and oil management and considerable less weight, noise, frixtionless vibration.
Department of Mechanical Engineering Submitted By: Centrifugal compressors are used in small gas turbine engines or as the final compression stage of medium sized gas turbines. This feature allows the compressor to see a power outage as a normal shutdown. Axial-flow co,pressor can be found in medium to large gas turbine engines, in natural gas pumping stations, and within certain chemical plants. Page count 1 page words. Seminar Report on Plastic Roads.
Traditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and lubrication system.
