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.

此外，船用機組分主機和輔機，大多數(shù)情況要求多機并聯(lián)，陸用機組視具體情況相對簡單，兩者使用條件也不一樣，船用發(fā)電機組是在內(nèi)陸河流或海洋上運行使用，因此防水、防潮、防鹽堿、抗沖擊、抗顛簸的能力有強制要求。

In addition, 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.

一般船用柴油發(fā)電機組及配套散熱器在制造時會考慮以下四項環(huán)境因素：

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

一、潮濕對發(fā)電機繞組絕緣及其他配件的損壞，特別是生銹問題，水箱箱體需防止銹蝕。

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.

二、船體振動顛簸對機組整體性能尤其是散熱器結(jié)構(gòu)影響大。

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

三、海洋環(huán)境中鹽堿腐蝕（因海水是堿性）對機組繞組及散熱器芯體腐蝕嚴重。

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

四、海上環(huán)境造成維修的不便。

4、 The marine environment causes inconvenience in maintenance.

陸用柴油發(fā)電機組及配套散熱器并不會專門針對以上四個方面去設(shè)計，而船用機組則考慮到以上因素，必須選用三防水箱，否則機組一旦使用必然會造成早期腐蝕、穿孔，基本無法維修且更換困難，國家也明文規(guī)定船用機組及部件必須要有三檢證書，檢驗合格的機組才允許在船上正常使用，處于類似環(huán)境的海島用機組也適用以上要求。

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.
