Turbine Main Shaft Seal Leakage: Understanding the Problem,
01-11-2010· Excessive leakage from the turbine main shaft seal wastes water that could be used for generation and can cause damage to the plant, including corrosion of the surrounding equipment. At this facility, the cumulative losses involved equate to about a 1% reduction in unit efficiency. The owners of this facility are now evaluating the situation,

Power Plant Electrical Distribution Systems Gary W Castleberry, PE 2008 PDH Center 2410 Dakota Lakes Drive Herndon, VA 20171-2995 Phone: 703-478-6833, This shaft connects to the main turbine shaft and rotates at the same rotational speed as the turbine. The field winding is located in slots machined into the rotor.
Shaft generators for low speed main engines
6 Shaft generators for low speed main engines Numerous designs exist for shaft generator systems, which MAN ES categorises in two subgroups: engine-to-generator and generator-to-grid. The engine-to-generator subgroup is related to the position of the shaft gen-erator and the connection between the engine and the shaft generator system.
How a Wind Turbine Works - Text Version | Department of Energy
How a Wind Turbine Works. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates,
Wind Turbine Parts and Functions | Electrical Academia
A major turbine part among these components is the generator and the turbine shaft that transfers the harvested power from wind to the generator through a gearbox. The gearbox is a vital component of wind turbines; it resides in the nacelle. A gearbox increases the main shaft speed from around 12–25 rpm* (for most of today’s turbines) to a,
What is Gearbox? Types, Parts, Working [Images & PDF]
10-03-2021· The main shaft turns with the clutch shaft and a gear ratio of 1:1 is obtained. The differential reduction produces a gear ratio of about 4:1 between the engine crankshaft and the wheels. Reverse Gear. Reverse gear, by operating the crankshaft lever, the larger gear of the main shaft meshes with the reverse idler gear.
What is Gearbox? Main components of Gearbox explained,
Main components of gearbox-1.Clutch shaft. Clutch shaft OR driving shaft is a shaft which takes power from engine to further supply to other shafts. As the name suggests, the driving shaft is connected via clutch & when the clutch is engaged, the driving shaft also rotates. The clutch shaft has only one gear fixed on it and it rotates with same speed as engine crankshaft.
2. GYRATORY CRUSHERS
short-shaft and the long-shaft with the short-shaft (Fig. 22) being the modern design. The short-shaft gyratories are distinguished by having the eccentric located above the bevel gear. The main frame has two sections, the upper shell supports the concaves while the lower shell contains the eccentric and the pinion shaft. The bevel

Hydro-Turbine Main Shaft Axial Seals of Elastic Polymer,
The main shaft seal in a hydro-turbine is one of the key components of the turbine system. Ideally, the seal should seal completely but due the size of typical units such an arrangement is prohibitively expensive. The main shaft seal therefore functions not to eliminate leakage but more to control the leakage to an acceptable amount.
