Sinooutput Marine Diesel generator sets

What is the marine generator function for the ships?

1. Providing power to ships. All electrical equipment on ships require power support, such as lighting, air conditioning, ship communication systems, satellite navigation systems, etc. The normal operation of these equipment requires power from marine generators.
2. Maintain ship safety. Some important equipment on ships, such as radars, navigation equipment, communication equipment, etc., all require power support. If the power is unstable or malfunctions, it will pose a great threat to the safety of the ship.
3. Improve navigation efficiency The use of marine generators can not only improve the efficiency of ship operation, but also reduce possible failures and downtime during navigation and ensure the stable operation of the ship.

In recent years, diesel engine generator sets have been increasingly used on ships. In addition to being used as a conventional unit to provide ship power, it is also increasingly used for electric propulsion. Due to its unique advantages, the use of full or semi-electric propulsion has become a development trend for propulsion systems for ships with thousands of tons or more, especially military ships. Diesel engines are mainly used as the prime mover of generator sets on ships. The fuel cooler is crucial for cooling the diesel oil of the diesel engine. The diesel engine cools the fuel through seawater to achieve the performance required by the diesel engine.

Sinooutput mainly supply the marine generator combined by the aux. Diesel engine brand such as Weichai, Deutz, Cummins, Yuchai, Sinotruk, Perkins, and the alternator brand such as Siemens, Marathon, Stamford etc. With the power range 3-2000KW/unit for the sea vessels and pleasure yachts with open and silent type.

For cost saving, we do suggest customers if your generator can work on deck, then by water and air cooled will be more economical than in the engine room by sea water cooling type, many customers tested them, the results is very good.

Marine generator Vibration problem and its reasons:

(1) Insufficient connection stiffness The base of the unit is thin and the support strength is not enough: the gasket connection between the base and the machine base is not good, the screws are loose, and the structural rigidity of the machine base is insufficient.

foot.

(2) The machine itself has defects. Due to long-term use and lack of maintenance, the gap between the moving pairs is too large, the moving parts are damaged, and unbalanced mass is generated.

produce unbalanced forces.

(3) Coupling defects: When the gear coupling is run for a long time, the gears will have uneven tooth thickness and tooth gap due to wear, and the tooth surface contact is poor; when the elastic pin coupling is run for a long time, the elastic rubber will be aged, deformed, and worn Falling off, the connecting rubber seat hole is worn and deformed, and the connecting screw is fatigued and broken. The rigid coupling has large plane runout, and the end face is not perpendicular to the shaft center, etc.

(4) The accuracy of repair and installation is poor. During the repair, the quality and clearance of moving parts are not considered when replacing moving parts: the center line adjustment of the motor and diesel engine is not up to standard.

The use of gaskets at the center line is unreasonable, etc.

Its harm:

Mechanical vibration often leads to excessive wear of bearings, the formation of cracks in mechanical parts, loose fasteners, structural and mechanical damage, frequent maintenance of mechanical equipment, and the resulting excessive costs, circuit failures caused by cracked solder joints, Short circuit caused by wear of insulating materials, etc. Workers will feel pain and discomfort in a vibrating environment for a long time, and their work efficiency will be low.
