发电机组作为平时工业生产中使用较为常见的发电设备，在使用的过程中也不可避免地会发生故障。但是为了能够避免故障，在使用的过程中不影响其使用效率，保证正常运行那么还是有必要了解一些使用技巧以及故障诊断知识。下面焦化发电机组厂家就从材料选择上为您讲解。

As a common generating equipment used in industrial production at ordinary times, generator sets will inevitably fail in the process of use. However, in order to avoid faults, not affect its efficiency in use, and ensure normal operation, it is necessary to know some skills and fault diagnosis knowledge. The coking generator set manufacturer will explain the selection of materials for you.

出现故障的原因

Cause of failure

在材料的选择上，或许是使用了一些不符合规定的零配件，经过长期使用也发生了较为明显的破损变形老化等现象。此外还有化学现象，也就是金属材料受到了腐蚀，以及受力过大导致出现变形，而油料当中所含有的酸性物质也会起到严重的腐蚀作用。比如发动机水套在高温的作用下气缸外套壁容易形成大量的水垢，其结果就会导致影响其冷却效果。

In terms of material selection, it may be that some unqualified spare parts have been used, and obvious damage, deformation, aging and other phenomena have occurred after long-term use. In addition, there are chemical phenomena, that is, the metal materials are corroded and deformed due to excessive stress, and the acid substances contained in the oil will also play a serious role in corrosion. For example, under the action of high temperature, the engine water jacket is easy to form a large amount of scale on the cylinder outer wall, which will affect its cooling effect.

外部原因

External causes

操作人员并没有按照正常的操作规范进行使用，比如经常出现低速运转，没有暖机的情况下就迅速增加负荷，这样就会导致机件的磨损速度会加快，此外超期负荷运行也容易导致零件过早损坏以及在平时使用过程中，没有按照相关技术要求规范进行维护保养，这样也容易导致相关零配件磨损速度加快。

The operator did not use it according to the normal operating specifications. For example, low speed operation often occurs, and the load is rapidly increased without warming up, which will lead to faster wear of the parts. In addition, the operation with overdue load is also likely to lead to premature damage of the parts, and the maintenance is not carried out according to the relevant technical requirements and specifications during normal use, which is also likely to lead to faster wear of relevant parts.

还有维修过程中存在技术不达标导致装配式没有清洁干净以及零配件配合间隙配合不大，那么也容易加速机件的损坏。还有柴油发电机，三相负荷电流不稳定，从而增加了额外的损耗，容易导致部分重要部件过热，也容易引发相关故障。

In addition, if the assembly type is not clean and the fitting clearance between parts is not large due to the substandard technology in the maintenance process, it is also easy to accelerate the damage of parts. There is also the diesel generator. The three-phase load current is unstable, which increases the additional loss, easily leads to overheating of some important components, and also easily leads to related failures.
