按照动力来源划分：

Divided by power source:

有柴油发电机组、燃气发电机组、汽油发电机组、风力发电机组、太阳能发电机组、水力发电机组、燃煤发电机组等

There are diesel generating sets, Gas-fired power plant sets, gasoline generating sets, wind generating sets, solar generating sets, hydro generating sets, coal-fired generating sets, etc

电能方式

Electric energy method

按转换的电能方式可分为交流发电机和直流发电机两大类。

According to the conversion method of electrical energy, it can be divided into two categories: AC generators and DC generators.

交流发电机又分为同步发电机和异步发电机两种。同步发电机又分为隐极式同步发电机和凸极式同步发电机两种。现代发电站中更常用的是同步发电机，异步发电机很少用。

Alternators are divided into two types: synchronous generators and asynchronous generators. Synchronous generators are divided into two types: hidden pole synchronous generators and salient pole synchronous generators. The most commonly used in modern power plants is synchronous generators, while asynchronous generators are rarely used.

不同用途以及使用环境适用于不同类型的机组，用户要根据具体的情况选择！

Different uses and usage environments are suitable for different types of units, and users should choose according to specific situations!

在采购发电机组的时候，一定要对它的具体设置时间以及用途进行一个全面的了解，如果是采购二手的就要向销售人员询问以前有没有发生过故障的情况有没有更换过什么零件，这样才可以对采购的设备有一个详细又全面的了解以便更好的估计发电机组的价值。

When purchasing a generator set, it is necessary to have a comprehensive understanding of its specific setting time and purpose. If purchasing a second-hand one, it is necessary to ask the sales personnel if there have been any previous malfunctions or replacement parts, so as to have a detailed and comprehensive understanding of the purchased equipment and better estimate the value of the generator set.

因为发电机组的市场利润是非常的大的，所以有很多无良商家为了得到更大的利益都用老的机组来代替新的出售，这种情况没有什么经验的新手都会受骗。

Because the market profit of generator sets is very large, many unscrupulous merchants use old units to replace new ones for greater profits. In this situation, inexperienced beginners will be deceived.

当这些基本的检查都做好了就可以进入下一步的试机，比如，摇转曲轴，如果发出的声音比较清脆，那么就表明发电机组的喷油嘴以及柱塞副的性能还是比较好的，而且还要看看飞轮上下扳动的时候是否有声响，有的话就说明它的曲轴主轴茎和轴瓦之间空隙比较大，通过系统化的检查可以有效的看出发电机组是否运作正常，另外还要看看起动机器，起动后如果排出的是无色的油烟，也没有杂音的话，那么就证明柴油机的技术状况是好的。

Once these basic checks are completed, the next test run can be carried out, such as shaking the crankshaft. If the sound emitted is relatively clear, it indicates that the performance of the fuel injection nozzle and plunger pair of the generator set is still good, and it is also necessary to check whether there is a sound when the flywheel is pulled up and down. If so, it indicates that the gap between the crankshaft main shaft and the bearing shell is relatively large, Through systematic inspection, it can be effectively seen whether the generator set is operating normally. In addition, it is also necessary to check the starting machine. If there is colorless oil smoke and no noise emitted after starting, it proves that the technical condition of the diesel engine is good.
