What is steam turbine governor valve?
In large turbines, a valve controls steam flow to groups of nozzles. The number of open valves controls the number of nozzles in use according to the load. A bar-lift or cam arrangement operated by the governor opens and closes these valves in sequence. Such a device is a multi-port valve. Using nozzles at full steam pressure is more efficient than throttling the steam.
Can you tell how emergency stop valve of turbine operates?
Unless it is an electronic governor on the turbine, there is a mechanical overspeed trip device which closes the trip valve (or trip throttle valve [TTV] on small turbines). This device is a spring loaded weighted pin set into the turbine shaft. At a particular set speed (110% of maximum operating speed, typically) the pin overcomes the force of the spring, flying part way out of the shaft and striking the trip mechanism linkage. This linkage up to that point was holding the trip valve open, now with the release of the linkage the spring on the trip valve instantly closes the valve stopping all flow of steam to the turbine. On electronic governors, when the set point on the turbine speed is reached it opens a solenoid valve (which requires a manual reset) which dumps all hydraulic pressure from the trip valve, allowing it to close.
How working the governor during steam turbine operate?
governor senses the speed of spindle of engine and controls the mechanism of opening and closing of throttle valve
What is critical speed of turbine?
SPEED OF TURBINE IS DEPEND ON THE WATER PRESSUR(7BAR)
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.
Where is the Turbine Shaft Speed Sensor located on a 1998 Explorer?
The turbine shaft speed (TSS) sensor is located inside the automatic transmission.
Where is the turbine shaft speed sensor on a 1996 Ford Ranger?
This engine has no turbine or turbo. Although the 1996 Ford Ranger does not have a turbine or turbo, it does have a turbine shaft speed (TSS) sensor. It is located inside the automatic transmission.
What is Runaway Speed of hydraulic Turbine and how it is calculated?
The runaway speed of a water turbine is its speed at full flow, and no shaft load. The turbine will be designed to survive the mechanical forces of this speed. The manufacturer will supply the runaway speed rating.

What is the Mercury Cougar Turbine Shaft Speed Sensor for?
are you sure it is not tail shaft sensor. This would be for your speedometer
Where is the input shaft speed sensor turbine located on a Mercedes cls 500?

What happens inside a wind turbine?
usually an wind turbine consists of large gears at its shaft point which produces slow speed to high speed to run the generator coupled to it
What du you understand by the term governing of steam engine?
A governor is a speed control device. It can be mechanical, hydraulic, pneumatic or electronic. It maintains a specific speed of rotation of the flywheel of the engine, or the shaft of a turbine, which is set by the operator. Governing an engine is just that, controlling the speed of the engine.
What is critical speed of steam turbin?
Answer:Turbine shaft material has its own natural frequency, when turbine rotates on such a speed that frequency of shaft become close to its natural frequency, machine causes noise & high vibrations because of resonance due to matching of frequency. Running of Steam "TURBINE" on this speed is avoided & this is called Critical speed. A turbine may have more then one critical speed, which may depend upon number of couplings.A second critical speed is when the Turbine blade tips approach the speed of sound. This effectively limits the speed of a turbine and explains why power plants tend to have turbines of the same capacity.Critical speed of the turbine is the rotor speed at which natural frequency of the assembled rotor (rotor shaft with discs, blades, shrouding strips etc in assembled condition) becomes equal to the operating speed. This is usually a expressed as a range (critical speed range).There are multiple critical speeds. However, the operating speed of the turbine may be above or below the first / lowest critical speed. Accordingly it is called as a flexible or a rigid rotor.Venkatesh
What does the input turbine speed sensor malfunctioning in a ford escort mean?
it controls the overdrive function and shift timing relative to speed
