Daily maintenance and maintenance of marine diesel generator sets? Marine 50Hz or 60Hz AC generators are mostly three-phase synchronous generators. According to the generator set, it can be divided into three types: gas generator, steam turbine generator and diesel generator. In some large ships and some ships, steam turbine generators or gas turbine generators are used. Generally, ships use medium-speed diesel generator sets. Other ships use low-speed shaft generators, mostly of medium capacity.

General maintenance:

For the generator to work normally, there should be no water, oil and dirt accumulation around it, and no corrosive gas, so as not to damage the generator winding insulation.

While preventing moisture and dust, pay attention not to affect the normal ventilation and cooling of the generator. Always clean the dust and dirt in the vents and keep them unobstructed. The temperature of the cooling air should not be too low to avoid condensation on the windings and other conductive parts.

For generators that stop running for a short time for some reason, the slip ring does not need to be wrapped for protection, but insulating cardboard, paraffin paper or asphalt paper should be placed between the brush and the slip ring to prevent the brush from being brushed on the surface of the slip ring— Spots are formed on the surface.

If the machined surface of marine diesel generator sets is rusted due to oil or paint peeling off, it should be derusted in time and painted with anti-rust paint.
