Marine Hydraulic Systems

 Hydraulic Systems Hydraulic systems have the ability to multiply torque or amove machinery at a distance from the engine. Hydraulic applies force in a simple way. Mechanical systems would require an intricate system of gears, chains, pulleys, and levers, systems, however, can transmit force from a force engine to the place where it needs to be in order to do the work simply by stringing hydraulic hoses between the two. Hydraulic Fluid, Pipes & Hoses Fluids transmit force effectively because they do not compress. The force that is applied at one end of a hydraulic hose travels to the opposite end of the hose with little loss of power. Changes in the size of hoses along the way can increase or decrease the force applied at the opposite end. Why Hydraulic? Because it can't be compressed, a confined fluid is incredibly strong, can be minutely adjusted in any direction, yet is still easily controlled. Most marine applications use small, easily installed components, with hydraulic l...

The Most Common Engine Cooling System

  Raw Water-Cooling Systems Raw water-cooling systems draw water from outside the boat (seawater or lake water). Water is pumped from the source to the engine block then the engine circulation pump forces the raw water thru the engine block and the water is expelled thru the exhaust. On larger engines and inboard engines, the raw water pump is located inside the boat and is driven by a v-belt or directly off of the crankshaft. There are hidden dangers that can accumulate over time causing you to spend big Dollars on repairs. The danger is using salt water as a coolant in your engine. Salt water can be highly corrosive. Get here the Marine Diesel Engines Book where you can find all the information on this and many other topics. Get the book Raw Water Pumps This pump sucks water from the sea. It typically goes through a strainer as it is sucked towards the pump. Saltwater Pump and Impeller Kit: A flexible impeller pump provides an efficient solution to most raw water pumping needs. T...
