The aft pressure bulkhead is the white circular component; its web-like structure led a NASA technician to attach a large model spider to it for comedic effect. The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [ 1 ]
A sound stuffing box installation is critical to safety because failure can admit a catastrophic volume of water into the boat. In a common type of stuffing box, rings of braided fiber, known as shaft packing or gland packing, form a seal between the shaft and the stuffing box.
A JIC bulkhead adapter, which converts National Pipe Thread (NPT) on the left to JIC on the right. The angled seating surface is clearly visible on the far right. JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface.
Radial shaft seal of Romo washing machine pump. Radial shaft seals, also known as lip seals, are used to seal rotary elements, such as a shaft or rotating bore.Common examples include strut seals, hydraulic pump seals, axle seals, power steering seals, and valve stem seals.
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads.It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged.
Most passenger vehicles and some freight vehicles will have a bulkhead which separates the engine compartment from the passenger compartment or cab; [11] the automotive use is analogous to the nautical term in that the bulkhead is an internal wall which separates different parts of the vehicle. Some passenger vehicles (particularly sedan/saloon ...
The tunnel is made up of separate elements, each prefabricated in a manageable length, then having the ends sealed with bulkheads so they can be floated. [1] At the same time, the corresponding parts of the path of the tunnel are prepared, with a trench on the bottom of the channel being dredged and graded to fine tolerances to support the elements.
A rocker cover, (UK), or valve cover (elsewhere) is a cover that encloses the rocker arm in an internal combustion engine, bolting with a gasket seal to the engine head. Engines with more than one head (such as a V8 ) will have multiple rocker covers.
