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.
This image shows the components needed to make a rotary union; a shaft, housing, bearings, seals and retaining clip. The independent shaft and housing allow for continuous rotation of either component. This is an example of a two passage rotary union with independent channels that allow both liquids and gases to transfer simultaneously. [1]
Air cylinders are available in a variety of sizes and can typically range from a small 2.5 mm (1 ⁄ 10 in) air cylinder, which might be used for picking up a small transistor or other electronic component, to 400 mm (16 in) diameter air cylinders which would impart enough force to lift a car. Some pneumatic cylinders reach 1,000 mm (39 in) in ...
