What is the difference between turbine turning gear and barring gear?
both are same using for rotating the turbine initially
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
Comparison between fluid coupling and torque converter?
They are of similar design, but a fluid coupling simply transmits torque (with some frictional loss), while a torque converter amplifies torque, similar to a reduction gear.
What are the types of coupling in software engineering?
control coupling content coupling common coupling data coupling external coupling message coupling
What are types of mechanical coupling?
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
What type of coupling used in alternator to align a turbine?
TRIVENI turbine TDPS ALTERNATOR [10 MW] COUPLING
Which type coupling used in steam turbine?
Membrane-type flexible coupling is used in steam turbines.
What is the difference between turbine turning gear and barring gear?
both are same using for rotating the turbine initially
What is scoop coupling?
Scoop coupling is nothing but a fluid coupling works based on the hydro dynamic principle. Scooping is the collecting the oil from the working chamber(space between pump wheel and turbine wheel) which will effects the transmission.
What is turbine rated speed and What is maximum speed rise of steam turbine?
Turbine rated speed varies mainaly on the factors of Generating frequency and means of coupling to generator (viz trough a gear box or directly coupled and no.poles in generator). For exmple a 50hz generting frequency and a bi-pole genarator the turbine speed is 3000RPM. The allowed speed rise also depends on turbine design and generator operational range. Generaly the speed rise is restricted to Maximum of 10% of the rated speed.
What does a gear box on a wind turbine do?
The gear box increaces the rotational speed from about 30-60. The gear box is very costly and heavy.
What is catenary in steam turbine?
generally more than three shafts contact by coupling together in steam turbine. the shaft is heavry and will be sag. in order to reduce the bend force on coupling and bend force on bearing, the engienering calclated the shaft and simulated when its in operation condition. so, the catenary curve and bearing elevation data have been provided for steam turbine installation.
What analogy is used to describe the gear system of a wind turbine?
Newton's third law governs in the turning of gears. Basically a torque is formed due to a coupling force. Now a large gear is joined with the pivoted point of the blades. When the blade turns the gear turns too turning other gears as well. Now why i said a large gear turning small gears is that for one rotation of a large gear a small gear does more rotation. So a small gust of wind turning the large gear to 1/100 th rotation turns the smaller gears to maybe 5 rotations. Now to the amazing part. Getting to produce the electricity. The gears turning is connected to a dynamo. The dynamo is responsible for producing the required electricity. And that is the total analogy of a wind turbine.
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
What is wrong with my BMW 325e It is shaking and making noise when accelerating in first and second gear?
propshaft coupling is damaged
What is a turbine barring gear?
When a large turbine rotor stops it will still be hot and will tend to bend in the middle if left to cool normally. To prevent this the barring gear will turn the rotor slightly at given intervals during the cool down period.
How does a wind turbine operate?
The Wind Turbine Generator (WTG) is broadly divided into three parts. • Tower • Nacelle • Rotor The tower of wind turbine generator supports the nacelle and the rotor. The nacelle contains the key components of the wind turbine, including the gear box, the electrical generator, control panels etc. The rotor blades convert the kinetic energy of the wind to electrical energy through gear box and generator. The hub of the rotor is attached to the gear box. The gear box has a low speed shaft for its input. The high-speed shaft of gear box rotates at approximately 1500 revolutions per minute (RPM) to drive the electrical generator system. The heart of the wind turbine is its controller, which is responsible for the operation of the whole turbine. The embedded software in the controller monitors the various inputs and other condition and controls/actuates the outputs accordingly.
