FLYWHEEL: FUNCTION, TYPES , DUALMASS FLYWHEEL, AND APPLICATIONS
What is flywheel?
A flywheel is an overwhelming pivoting body which goes about as a store of vitality. It goes about as a bank of vitality between the vitality source and hardware.
Vitality put away in a flywheel is as dynamic vitality.
Elements of flywheel
- It is utilized to store vitality when accessible and supply it when required.
- To decreases speed vacillations.
- To decrease control limit of electric engine or motor.
Utilizations of the flywheel can be comprehensively isolated into two sections dependent on wellspring of intensity accessible and the sort of driven hardware.
Work of flywheel
- At the point when the power accessible at variable rate however is required at uniform rate. For e.g. the apparatus driven by responding inward burning motor.
- At the point when the power is accessible at uniform rate however we require it at non-uniform rate. For e.g. control required in punching press. For this situation we require sudden power at punching stroke.
Sorts of flywheels
Based on precise speed, flywheels can be isolated into two kinds.
- High Velocity Flywheel
The rakish speed of these kind of Flywheels divides 30000 rpm to 60000 rpm which may even be balanced upto 100,000 rpm. They contain attractive levitation orientation and need less support. They are lighter in weight whenever thought about size/limit insightful to low speed flywheels. They are expensive in contrast with Low speed Flywheels.
- Low Velocity Flywheel
The precise speed of these sort of Flywheels comes up to 10000 rpm. They are massive and overwhelming whenever contrasted with high speed Fly wheels. They require intermittent support and does not utilize attractive levitation direction. Their establishment needs uncommon solid development to help its weight. They are less expensive in contrast with high speed Fly wheels.
Double Mass Flywheel, and What Does It Do?
A double mass flywheel, or DMF, acts a similar way a traditional flywheel acts. There are a few preferences, and drawbacks to utilizing this plan. This is what you have to think about the motivation behind a double mass flywheel.
The double mass flywheel is essentially intended to diminish commotion and vibration. The DMF is kind of a mechanical “wipe”, where vibrations and cruelty in the driveline are hosed by two flywheel masses that are associated with each other by a progression of high quality springs. Any harshness is assimilated (at any rate incompletely) by the springs between the flywheel masses.
It might think about a double mass flywheel as a safeguard: every flywheel is a strong association, yet between there is a “delicate” spring that removes a portion of the shock from increasing velocities, outfit changes, and so on.
Difference between flywheel and governor
Numerous individuals befuddle among flywheel and senator, however they are absolutely two distinct things. Here are a few contrasts between a them.
A flywheel is utilized to moderate cyclic vacillations in accessible vitality yet a senator is utilized to change the supply of fuel according to the heap.
The vitality put away in inaccessible flywheel is dynamic which is 100% accessible however senator instrument includes rubbing.
Flywheel isn’t utilized when cyclic variance of vitality is little or irrelevant. While a senator is essential for every one of the sorts of motors since it confines the fuel supply according to request.
If we have steady load then representative will stay inert yet because of cyclic changes in vitality accessible, flywheel will dependably work.
Governor has no impact in cyclic vacillations in vitality and flywheel has no effect on the mean speed of motor.
Governor controls mean speed of the motor and flywheel controls cyclic vacillations in vitality.
Advantages of flywheel
- Less by and large expense
- High vitality stockpiling limit
- High power yield
- They are sheltered, solid, vitality productive, tough
- It is free of working temperatures
- Low and economical upkeep
- High vitality thickness
Disavantages of flywheel
- They can take a great deal of room
- They are costly to produce building material is dependably a constraint for it
Uses of Flywheels
- In responding inner ignition motors
- In wind turbines
- In train drive framework
- In satellites to control bearings
- In Mechanical workshops
- In punching machines
