Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]
In October of 2024 the Day Peckinpaugh was sold at auction by the New York State Education Department. They were the then owners but could no longer afford the $20,000.00 to $30,000.00 a year cost to just keep the Day Peckinpaugh from sinking. Pumps running constantly were keeping the boat afloat. The minimum bid level was $5,000.00.
The key distinguishing feature of a narrowboat is its width, which must be less than 7 feet (2.13 m) to navigate British narrow canals. Some old boats are very close to this limit (often built 7 feet 1 + 1 ⁄ 2 inches or 2.17 metres or slightly wider), and can have trouble using certain narrow locks whose width has been reduced over time because of subsidence.
The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps. Invented around the early 3rd century BCE, the most primitive design of a force pump consisted of a piston pushing water out of a tube, constructed by soldering individual bronze elements (Stein 246).
The caisson lock is a type of canal lock in which a narrowboat is floated into a sealed watertight box and raised or lowered between two different canal water levels. It was invented in the late 18th century as a solution to the problem posed by the excessive demand for water when conventional locks were used to raise and lower canal boats ...
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
Like all rudders, the main effect of a Schilling rudder is to deflect the flow of water generated by the propeller.Schilling rudders are most commonly used on ships that are difficult to maneuver, particularly large ships such as container ships and oil tankers, slow-moving ships and boats, longer and narrower ships, or boats with slow-moving propellers.
In 1859, after establishing a pump-manufacturing plant in New York, he perfected his duplex steam feed pump (patent No. 24,838) and in the following year built the first water-works engine of this kind. In the duplex system one engine actuated the steam valves of the other, and a pause of the pistons at the end of the stroke permitted the water ...
