In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring. When operating, lifting geometry in the rotating ring generates a fluid-dynamic lifting force causing the stationary ring to separate and create a gap between the two rings.
The heart of the rotary union is the seal. The seal prevents the medium from leaking outside the rotary union while in operation. Seal types can vary from pusher-type end face mechanical seal, non-pusher type end face mechanical seal, lip seals, and o-ring seals. Most rotary unions have more than one seal. [6]
The Falkirk Wheel A timelapse of the wheel rotation. This video covers a time period of 10 minutes A timelapse from inside a boat. The Falkirk Wheel (Scottish Gaelic: Cuibhle na h-Eaglaise Brice) is a rotating boat lift in Tamfourhill, Falkirk, in central Scotland, connecting the Forth and Clyde Canal with the Union Canal.
After his mother's death, Antonio (nicknamed Tottòi in Sardinian language) and his father move to Sardinia, where Tottòi's father grew up as a boy.Tottòi's adventures begin when he sees a monk seal, despite the common belief that they had long since died out.
Klum gave birth to daughter Leni in May 2004, and Seal adopted the little one five years later. The singer and Klum went on to welcome Henry, Jonah and Lou in 2005, 2006 and 2009, respectively ...
Ferrofluid-based seals used in industrial and scientific applications are most often packaged in mechanical seal assemblies called rotary feed-throughs, which also contain a central shaft, ball bearings, and outer housing. The ball bearings provide two functions: maintaining the shaft's centering within the seal gap and supporting external loads.
The Main rotor attach nut, or "Jesus nut", from a Bell 222U, shown in hand for size perspective (left) and installed with locking key (right). Jesus nut is a slang term for the main rotor retaining nut [1] or mast nut, which holds the main rotor to the mast of some helicopters.
