A bilge pump is a water pump used to remove bilge water. Since fuel can be present in the bilge, electric bilge pumps are designed to not cause sparks. Electric bilge pumps are often fitted with float switches which turn on the pump when the bilge fills to a set level. Since bilge pumps can fail, use of a backup pump is often advised. The ...
The water ladder was built as an alternative to the paddle wheel to get around the problem that to lift water to a greater height, a bigger wheel is needed. [1] Despite the emergence of new pumps that operate on other principles, the water ladder remains an important tool as some of its other benefits are that they can be built and repaired easily at a very low cost.
The most prevalent hydraulic pump used in maritime situations in ancient Rome was the bilge pump, which functioned to siphon collected water out of a ship's hull (Oleson 1984). The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps.
Bilge compartment in a steel hulled ship (looking down) Bilge compartment and pump. The bilge / b ɪ l dʒ / of a ship or boat is the part of the hull that would rest on the ground if the vessel were unsupported by water. The "turn of the bilge" is the transition from the bottom of a hull to the sides of a hull.
The ladders are made by threading and fixing a series of hardwood, machined steps, each not more than 400 mm × 115 mm × 25 mm (15.75 in × 4.53 in × 0.98 in), onto two pairs of minimum 18 mm (0.71 in) diameter manila ropes, and binding each step to the ropes at 310 mm (12 in) (+- 5 mm, 0.20 in) intervals.
The automatic lubrication system is connected to a control system via switchs. The control system may involve human input or may be computerised (computer numerical control or CNC). [2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The ...
Person on the 1837 man engine at the Samson Pit in Lower Saxony, Germany Bottom of the man engine at the Dolcoath Mine, Cornwall. The earliest known examples of this device were from the first half of the nineteenth century in the silver mining area of the Harz mountains, Germany, where they were driven by cranks connected to water wheels, although bucket hoists ("Hakenkunst") using the same ...
A quintuple combination pumper or quint is a fire-fighting apparatus that serves the dual purpose of an engine and a ladder truck. “Quintuple” refers to the five functions that a quint provides: pump, water tank, fire hose, aerial device, and ground ladders. [1] Tillers and tractor-drawn aerials also have quint features, and are dubbed ...
