發電機組作為平時工業生產中使用較為常見的發電設備，在使用的過程中也不可避免地會發生故障。但是為了能夠避免故障，在使用的過程中不影響其使用效率，保證正常運行那么還是有必要了解一些使用技巧以及故障診斷知識。下面焦化發電機組廠家就從材料選擇上為您講解。

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.

出現故障的原因

Cause of failure

在材料的選擇上，或許是使用了一些不符合規定的零配件，經過長期使用也發生了較為明顯的破損變形老化等現象。此外還有化學現象，也就是金屬材料受到了腐蝕，以及受力過大導致出現變形，而油料當中所含有的酸性物質也會起到嚴重的腐蝕作用。比如發動機水套在高溫的作用下氣缸外套壁容易形成大量的水垢，其結果就會導致影響其冷卻效果。

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

操作人員并沒有按照正常的操作規范進行使用，比如經常出現低速運轉，沒有暖機的情況下就迅速增加負荷，這樣就會導致機件的磨損速度會加快，此外超期負荷運行也容易導致零件過早損壞以及在平時使用過程中，沒有按照相關技術要求規范進行維護保養，這樣也容易導致相關零配件磨損速度加快。

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.

還有維修過程中存在技術不達標導致裝配式沒有清潔干凈以及零配件配合間隙配合不大，那么也容易加速機件的損壞。還有柴油發電機，三相負荷電流不穩定，從而增加了額外的損耗，容易導致部分重要部件過熱，也容易引發相關故障。

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.
