With the advent of the gasoline-powered outboard motor, the use of electric power on boats declined from the 1920s. However, in a few situations, the use of electric boats has persisted from the early 20th century to the present day. One of these is on the Königssee lake, near Berchtesgaden in south-eastern Germany. Here the lake is considered ...
[c] These are supplementary pumps and do not replace the main, mechanical, oil pump. Electric pump as a main engine pump again will require big electric motors and it may be simply cheaper to drive directly from the engine. For e.g. BMW S65 engine's oil pump delivers ca. 45 LPM (Litres Per Minute) of oil at 5.5 bar pressure. [5]
A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
Membrane pump on an oil tanker deck, to evacuate any leak down to the slops tanks. One of the firefighting pumps on the salvage tug Abeille Bourbon Electrical motors for ballast water pumps — on the oil tanker Algrave. A Marine pump is a pump which is used on board a vessel or an offshore platform.
Despite the large expenditures, OMC's decision to focus on boatbuilding proved to be a good one. OMC was able to pair boats with appropriately powered outboards and sales of boat packages doubled within a one-year timeframe. Smaller and quieter V-6s were introduced in 1991 in the form of the Evinrude Spitfire and the Johnson Silver-Star series.
Among the products making their debut are two new electric outboard motors, part of the Avator line of electric outboards. Outboard motors are better suited for electric power, since they are used ...
Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...
