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 ...
A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap ( faucet ) where the gland is usually packed with string which has been soaked in tallow or similar grease.
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
A cable gland (more often known in the U.S. as a cord grip, cable strain relief, cable connector or cable fitting) is a device designed to attach and secure the end of an electrical cable to the equipment. [1]
The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump. Eccentric reducers exhibit a unique design with one side having a larger diameter and the other side being smaller and offset from the centerline.
Inside of a 231 New Process Gear transfer case. Part-time/Manual, shift on the fly Part-time/Manual, shift on the fly A transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive , all-wheel-drive , and other multi-axled on- and off-road machines.
A concentric reducer is used to join pipe sections or tube sections on the same axis. [1] The concentric reducer is cone -shaped, and is used when there is a shift in diameter between pipes. [ 1 ] For example, when a 1" pipe transitions into a 3/4" pipe and the top or bottom of the pipe doesn't need to remain level. [ 2 ]
Piston water pump, with a scotch yoke connection to its flywheel. This setup is most commonly used in control valve actuators in high-pressure oil and gas pipelines.. Although not a common metalworking machine nowadays, crude shapers can use Scotch yokes.
