The Francis turbine is an inward flow turbine that is the most efficient and widely used water turbine in the world today. It works best in higher head (pressure) applications, and hydroelectric power plants at big dams use these guys to make lots of watt-hours.. The term "inward flow" means that t…he turbine itself (the thing with the blades that the water "presses on" to make the thing turn) has the water directed from the outside of the turbine wheel in onto the blades, and through them to a "center area" for the water to exit. The unit is darn efficient. Pictures are a mouse click away. Use the link to surf on over to our friends at Wikipedia (from which some of the data here was gathered) for more information and the cool pics that really show a viewer how the unit works.

A turbine is an engine that uses energy from the flow of liquid.Turbines can be found in jet engines, the engines of aircraft, andare responsible for most of the electricity produced on our planet…. A turbine is a machine with a shaft or drum with bladesattached. When the turbine turns energy is extracted from what everis making the turbine turn, for example wind or water or steam. Theturning of the turbine is used to generate electricity ( Full Answer )
It is an engine. A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around… the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine. ( Full Answer )
Turbines are attache to either alternator or generator which converts mechanical energy to electric energy. Turbines convert the kinetic energy into mechanical energy. (Eg. steam turbine is a prime-mover in which te potential energy of the steam is transformed into kinetic energy and latter in its t…urn is transformed into the mechanical energy of the rotation of the turbine shaft) ( Full Answer )

(n.) A form of steam engine analogous in construction and action to the water turbine. There are practically only two distinct kinds, and they are typified in the de Laval and the Parsons and Curtis turbines. The de Laval turbine is an impulse turbine, in which steam impinges upon revolving blades …from a flared nozzle. The flare of the nozzle causes expansion of the steam, and hence changes its pressure energy into kinetic energy. An enormous velocity (30,000 revolutions per minute in the 5 H. P. size) is requisite for high efficiency, and the machine has therefore to be geared down to be of practical use. Some recent development of this type include turbines formed of several de Laval elements compounded as in the ordinary expansion engine. The Parsons turbine is an impulse-and-reaction turbine, usually of the axial type. The steam is constrained to pass successively through alternate rows of fixed and moving blades, being expanded down to a condenser pressure of about 1 lb. per square inch absolute. The Curtis turbine is somewhat simpler than the Parsons, and consists of elements each of which has at least two rows of moving blades and one row of stationary. The bucket velocity is lowered by fractional velocity reduction. Both the Parsons and Curtis turbines are suitable for driving dynamos and steamships directly. In efficiency, lightness, and bulk for a given power, they compare favorably with reciprocating engines. . (n.) A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel.

How does increase in VAR cause increases in bearing damage caused by shaft vibration in the shaft connecting turbine to generator in a 210 MW turbine-generator set?
Another answer which was given to this question is now in the Discussion Area. It gives advice about running small domestic motor-generator sets but does not address the actual question here which is about the kind of turbine-alternator set used in a major power station capable of generating up to 2…10 MegaWatts of power.. Because of the highly technical details given in the question it is clear that it is probably from an exam in electrical engineering and not one on electrical wiring.. The full answer to this question would take a chapter in a heavy book about the design of turbine-alternator sets, the kind usually held in an engineering/technical library! Whilst the student should really use his recommended course materials, for those who may be interested this may be a possible part-answer:. VAR means "VoltAmps Reactive". . In the ideal world there would only be purely resistive loads so that there would be no large currents out of phase with the generated voltage taken by loads having high power factors. . Such out of phase currents can easily lead to shaft vibrations between the alternator and the turbine and, if no steps are taken to improve the power factors of the loads which are causing the problem, such vibrations could quickly wreck the turbine/alternator shaft's bearings. . Real-world alternators have to handle out of phase currents but, for the reason implied by this exam question, such currents must always be minimized. . Electric power utility companies always monitor their output for the appearance of any new heavy out of phase current loads. If they see any they take strong action to enforce their supply contract terms to make the consumers who are responsible disconnect their damaging loads until the appropriate power factor correction equipment has been installed. . To view or take part in the Discussion click on the View Discussion button below.. . Important Note: To find out how it should be done in a safe and legal manner, before you try to connect a generator to your home electricity circuits you would be very wise to read the answer to the Related Question shown below: "How would you connect a generator when the power is off?".. ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING - ELECTRICAL SERVICE PANEL, BREAKERS, CABLES OR OUTLETS - ON ANY ELECTRICAL POWER CIRCUITS . IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. . If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use an electrician's test meter having metal-tipped probes (not a simple proximity voltage indicator) to insure the circuit is, in fact, de-energized..

Water traels thru a pipe called a penstock then hits a turbine and the force makes the turbine spin. The energy created travels thru copper coil and goes to the generator. the water meanwhile goes to the river
Wind turbines are for catching the kinetic energy of the wind and transforming it into electricity.
A turbine trip is an automatic shutdoen to protect the wquipment from over-speed damage. It is similar to blowing a fuse on an electrical system die to a short circuit. ------------------------------------------------------------------------------------------- Any device which will instantly shut… down the turbine. There are high vibration trips, overspeed trips, high bearing temperature trips, low lube oil pressure trips, eccentricity trips, axial position trips, and for generating units: out of phase trips, low voltage trips, high voltage trips, reverse power trips, power to ground trips, and a few others.

A turbine is most commonly connected to a generator to produce electricity. The turbine may be turned by water falling into it, and a generator produces electricity by turning through a magnetic field.
Should be spelled "tidal". It is a mechanical device that converts the energy from tides (ocean tides) into electricity.
Any moving fluid can power a turbine. This includes air, water, steam, burning fuel etc. When the fluid strikes the blades of the turbime it transfers energy to the blade causing the blade to move.
If there were no operating clearance the clutch release bearing would constantly be in contact with the spring diaphragm causing wear on both the diaphragm and the bearing itself, also the bearing pushing on the diaphragm could cause the clutch friction plate to not be fully engaged and slip.
Turbine Helios comes with a ripcord. There are two L shaped holes in his wings. Put the ripcord through the left hole (teeth facing Helios's back). Pull the ripcord really hard and release immediately. Turbine Helios starts spinning and lands on the metal gate card. Sometimes, it keeps spinning… when it lands on the card. So basically, Turbine Helios spins. There is also a Turbine Hades. ( Full Answer )
There is no simple formula to calculate the metal bearingclearance. Manufacturers must specify the clearance for eachindividual bearing.
An electric turbine in a large machine that has the ability toextract raw energy through wind, water, or other such naturalsource and convert it into a workable form of energy. One exampleof electric turbines at work can be seen with windmills.
Bearing clearance is the distance between the crankshaft journal and the bearing surface. It is usually referred to as oil clearance, as that's what is occupying the space.
Quite simply, a turbine is any device that converts fluid motion into usable energy. The first turbine would either be the aeolipile (ca. 100 BCE), which was two opposite vents that created thrust in one direction using steam, or naturally powered machines such as windmills and water wheels.
Why is it important to have an operating clearance between the clutch release bearing and spring diaphragm?
in order to prevent continuous rotation of the release bearing. This prevents premature wear of the bearing. To ensure that the full spring pressure and clamping force is applied at the clutch contact faces. This prevents clutch slip.
The thrust pads will be there at the front or non drive end of the turbine side....These are usually used to limit the axial displacement of the rotor( Means to minimize the movement of rotor axially in order to maintain the axial clearance between the moving blades and the fixed blades of steam tur…bine rotor).....

Why is it necessary to wipe dry bearing and journal before using a plastigauge when measuring bearing clearance?
You wouldn't want oil to be taking up part of your clearance and give a false reading with the plastigage.
Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burner
A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work. The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades, or the blades react to the flow, so that they move and… impart rotational energy to the rotor. Early turbine examples are windmills and water wheels Gas, steam, and water turbines usually have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to the British Engineer Sir Charles Parsons (1854-1931), for invention of the reaction turbine and to Swedish Engineer Gustaf de Laval (1845-1913), for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. A device similar to a turbine but operating in reverse, i.e., driven, is a compressor or pump. The axial compressor in many gas turbine engines is a common example. Here again, both reaction and impulse are employed and again, in modern axial compressors, the degree of reaction and impulse will typically vary from the blade root to its periphery. ( Full Answer )

Can Steam Turbine Thrust Bearing temperature protection device be considered a similar protection for the Steam Turbine Rotor Position protection device?
No these are two different sensors. The thrust bearing temperature trip device measures either the metal temperature of the bearing, or the oil temperature exiting the bearing, or both. If this temperature exceeds recommended temperatures by 10 to 15% the turbine will trip to avoid damaging the bea…rings or shaft. The rotor position sensor is a proximity cell that monitors the axial position of the turbine rotor, often there is four such sensors mounted at the end of the rotor, if the distance between the sensors and the rotors exceeds a specific distance ( often 15-30 mils) the sensors indicate a failure, if two or three sensors indicate failure the turbine will trip.

To keep from damaging the thrust bearing if the lubrication system fails to cool it sufficiently. The surfaces of thrust and journal bearings is a metal called babbit. Babbit metal is an alloy of tin, lead, copper and antimony, typically. This metal has a high "lubricity" value (meaning it is slippe…ry) and oil is used to create a wedge or film, to stabilize the shaft in position, which decreases as the oil gets hotter. Babbit will also melt at low temperatures, so temperature trips are in place on each bearing to prevent damaging them. ( Full Answer )

Type your answer here... If your looking in a book then you need to find rod bearing clearance SPECS. for your year and engine SIZE.
Thrust bearings are mounted on turbines at or near the end of the shaft, closest to the steam chest (or inlet). This is to maintain the shaft in position with the casing of the turbine, allowing the casing and the shaft to expand evenly together toward the drive end of the turbine.
It is oil used to lubricate the bearings on the turbine. Typically designated AW32 oil, it is a high purity clear amber 300 ssu viscosity mineral oil with anti-wear additives. It is also used to operate the turbine's controls, such as the governor, trip mechanisms and admission valves.
