The marine generator set is affected by multiple environmental climates, so the diesel generator set and the supporting radiator must meet the requirements of marine regulations before use, otherwise it will cause safety hazards and use problems.

dition, marine units are divided into main engines and auxiliary engines, and in most cases, multiple machines are required to be connected in parallel. Land units are relatively simple depending on the specific situation, and the usage conditions of the two are also different. Marine generator sets are operated and used on inland rivers or oceans, so there are mandatory requirements for waterproof, moisture-proof, salt alkali resistant, impact resistant, and bumpy resistance.

The following four environmental factors will be considered in the manufacturing of general marine diesel generator sets and supporting radiators:

 

1、 Moisture can cause damage to the insulation and other accessories of the generator winding, especially rust. The water tank body should be protected from rust.

 

2、 The vibration and turbulence of the ship have a significant impact on the overall performance of the unit, especially the radiator structure.

 

3、 Saline alkali corrosion in the marine environment (due to the alkalinity of seawater) severely corrodes the unit windings and radiator cores.

 

4、 The marine environment causes inconvenience in maintenance.

The onshore diesel generator set and supporting radiator will not be designed specifically for the above four aspects, while the marine unit must use the three prevention water tank in consideration of the above factors, otherwise, once the unit is used, it will inevitably lead to early corrosion, perforation, basic inability to repair and difficulty in replacement. The state also explicitly stipulates that the marine unit and components must have the three inspection certificate, and the unit that passes the inspection can be used normally on board, The above requirements are also applicable to island units in similar environments.
