Marine Diesel generator set

Fuel system has adopted the A type injection pump and closed multi-hole nozzle. First grade fuel filter is supplemented before the original fuel filter, which has guaranteed the fuel cleaness and prolonged the life of the injection pump.

Fuel system                    

Power output from the front and can meet the needs of driving the seawater pump, generator, steel wheel pump, fish bet elevator and other appliance. And there are many kinds of belt wheel given for the choice.

Crankshaft front and output

There are these kinds of flywheel shell for choice: SAE, SAE, 6135C.

Flywheel and flywheel shell

226B series marine diesel engine equips with the advanced YD901 or YD908 series diesel engine monitor. The monitors are all PC controlled. The car measure and display automatically the diesel engine speed cooling water temperature, oil temperature and speed, cooling water temperature.

Apparatus monitoring system

Structure : specialized exhaust pipe is designed for marine diesel engine. The exhaust pipe is cooled by sea water through sea water and fresh water exchanger or inner cooler. This tructure can reduce the surface temperature of exhaust pipe to below 60.

Structure : the surface of the exhaust pipe is smeared with special warm-proof by special technology, which has lowered the temperature in the engine room. Steel cover is added to the exhaust pipe to prevent people from scalding by the protruding tighten bolts.

The intake and exhaust system has been improved more to adapt the special circumstance for the ships to haul fishnets.

Intake and exhaust system

The type of cooling system is still closed and compelled cooling. According to the circumstance(tropics, semi-tropics, temperature-zone and etc), people can choose 55, 75 and 85 after the circulation. Cooling pipes of the seawater-freshwater exchanger are made of brass pipe, and its cooling is assembled by the advanced expanding-connection technology.

Fresh water cooling system

Impeller shaft of seawater pump is made of stainless steel. Impeller and sealing ring are made of brass that is eroding-resistant and can prolong their life greatly. In addition to this, there are other kinds of seawater pump and double-suck seawater pumps that have more rate of flow and higher life for the customer.
