why we are maintain vacuum in steam turbine at steam outlet or exhaust side
Vacuum cleaners are a good example of suction cups.
Neither of them are simple machines. A vaccum cleaner is composed of several simple machine, (I don't really know what) and a bicycle is composed of a wheel and axle (the two wheels), pulleys (the gears), and levers (Brake handles and pedals).
Oh, dude, let me blow your mind - vacuums use a simple machine called a "suction pump" to suck up all those crumbs you drop while binge-watching Netflix. It's like a magical vortex that just slurps up all your mess without you having to lift a finger. So next time you're vacuuming, just remember you're basically operating a mini ghostbusters trap.
A rupture disc or blow out panel is a non-reclosing pressure relief device that protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions. Rupture discs are commonly used in petrochemical, aerospace, aviation, defense, medical, railroad,nuclear, chemical, pharmaceutical, food processing and oilfield applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the rupture disc will burst. Rupture discs are very often used in combination with safety relief valves, isolating the valves from the process, thereby saving on valve maintenance and creating a leak-tight pressure relief solution.
Well, darling, the only simple machine that starts with the letter "v" is the wedge. It's like a little slice of heaven for splitting things apart. So, if you're looking to make a clean break, just remember: "V" is for wedge.
Think of a solid state triode vacuum tube, the mathematical model is almost identical.
A gland condenser on a steam turbine is a component designed to manage the exhaust steam and maintain a vacuum in the turbine's sealing system. It collects steam that leaks from the turbine's gland seals, condensing it back into water to reduce steam loss and improve overall efficiency. By maintaining a vacuum, the gland condenser helps optimize turbine performance and prevents air ingress, which can reduce efficiency and increase operational issues.
it is mainly provided to save the difram of lp turbine, it is initially use to seal d vacuum's.
A vacuum breaker is a check valve installed on the exhaust casing of a turbine. It opens to prevent the collapse of the exhaust hood when the turbine cools and the condensing steam produces a vacuum.
A kenotometer is an instrument used in steam turbine condensers to measure the vacuum in the steam space of the condenser. The vacuum achieved by the condenser has significant influence on the efficiency of the steam turbine.
Vacuum dropping in a steam turbine can be caused by air leakage into the system, inadequate steam supply, malfunctioning condenser or cooling system, or excessive steam flow rate. This drop in vacuum can reduce the efficiency of the turbine and impact its performance. Regular monitoring and maintenance of the system are essential to prevent issues leading to vacuum drop.
yes that is centrifugal pump because the turbine pump creates a vacuum pressure on pipe.
It is important to maintain a vacuum in a condenser if you want it to work well.
If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).
For increasing steam turbine efficiency. if vacuum is not maintained then, uncondensable gases and air in condenser will increase the condenser pressure.
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
The barometric leg in a barometric condenser is required to create a seal that prevents the ingress of air into the condenser. This seal helps maintain a vacuum within the condenser, which is essential for efficient steam turbine operation. The barometric leg allows air and non-condensable gases to be removed from the system to maintain the desired vacuum level.
