The diesel engine is better than all other engines in terms of flexibility, performance, emissions and sustainability, particularly in the context of the current debate of CO2. The intensive search for alternative propulsion concepts, such as hybrid or pure electric drives, the indispensability of diesel engines for the cost-effectiveness, demonstrating

Learning to understand your cooling system marine diesel is a necessary part of the basic maintenance of marine diesel engines.



flexible impeller pump provides an effective solution for most of the water must be pumped. The main advantage of flexible impeller pumps is that they are self-priming, which means that when the blades of the turbine are depressed and recreation, they create their own vacuum, the liquid in the pump means. A dry pump can lift water up to as much as three meters. Such a centrifugal pump used for cooling the engine should not be initiated manually or below the waterline. An additional feature includes a flexible impeller pump is large enough that they clog without damage or pass through the pump. This reduces the need for liquid filtration entrants.

For general applications or fresh water, uses a standard wheel-resistant neoprene rubber.

A general feature of all flexible impeller pumps is that they are not allowed to run, be sober for more than 30 seconds. Both the turbine and the joints of water for lubrication and burn soon, if run dry. Parts that are beginning to bear are easily replaceable and service kits are readily available for most models.



traffic from the inside, closed circuit fresh water cooling system, it is customary to use a pump soft rubber, if it is on the cold side of the system (max. 55 ° C). Other types of belt centrifugal pumps are also used. The closed circuit normally transfers the heat from the engine heat exchanger. The liquid used is water and />

The required capacity of the type of engine cooling pump and size, and not the size of the heat exchanger and a system exhaust. This is true both for fresh and raw water systems, water handling.



thermostats are usually located in the socket at the top of the cylinder head to prevent movement of the coolant in the tank to motor the boat reached operating temperature is almost.

There are different types of thermostats, the most common being the wax pellet type. The capsule on the bottom of the thermostat (to increase the thermal conductivity), a mixture of wax and copper sealed in it. As the temperature of the coolant increases, the wax expands and forces the stem to the valve plate in the top of the thermostat, which leaves open the coolant circulates.

To test your thermostat, cook a pot with water and lower the thermostat. (The water should be 100 degrees Celsius -. The thermostat usually opens at 85 degrees Celsius) when the thermostat opens, it's okay. If it does not open, replace or clean it thoroughly, as it became sticky with inserts. Yanmar thermostats can and should be maintained regularly. Some thermostats can not be exploited. If the thermostat does not work, do not remove it and run the engine without it, the engine is cold and dense. You can drill a series of 1 / 4 inch? Holes flow rate equivalent to a type thermostats open. It will be at home, but you must be replaced. To adjust the thermostat on the head. Thermostat housing often corroded and need replacing. Some can be produced. The cooling system should be checked after 100 hours, or at least once a year for leaks, debris, etc. The thermostat can be removed from the box on the front of the engine. The core heat exchanger must be removed every six months for cleaning and inspection. Many heat exchangers are equipped with anodes to protect the core price. Check regularly. Regularly check all hoses and clamps.

The turbine is made of neoprene and can be damaged by water shortages, for example, when the sea water intake must be blocked. The shooting guide wheel problem will be helpful in identifying problems turbine. The turbine pump seawater is amended as follows:

Remove the pump seawater Note that there is a risk of water in the boat. Use two screwdrivers to tighten the shaft with the wheel housing to the extent necessary to reach the screws of the wheel. Put some kind of protection under the screwdriver to avoid damaging the casing of the wheel. Alternatively, channel-lock pliers with the jaws slide between the blades of the turbine to rotate and retire. Pull the wheel shaft. Clean the inside of the casing and adapt to the new turbine. Always have a spare wheel on board. Check that the clutch of the pump is not damaged by trying to turn the turbine. Replace the cover with the original seal, which has the right thickness.
