燃气发电机组运行过程安全环保，有效降低了污染物的排放，运行时须采取有效的措施予以防范，并做到发生故障及时处理与解决，尽量避免发电机组出现故障问题，下面来看看它的故障的诊断及防范建议。

The gas-fired generator unit is safe and environmentally friendly during operation, effectively reducing the emission of pollutants. Effective measures must be taken to prevent the operation, and timely handle and solve the failure, so as to avoid the failure of the generator unit as much as possible. Let's take a look at its fault diagnosis and prevention suggestions.

故障诊断的方法

Methods of fault diagnosis

（1）部分停止法。停止疑似造成故障部位的工作看故障是否消失以验证判断是否正确。

(1) Partial stop method. Stop the work of the part suspected of causing the fault to see if the fault disappears to verify whether the judgment is correct.

（2）比较法。更换可能造成故障的部件，然后对更换前后的故障现象进行比较，以确定或排除判断。

(2) Comparative method. Replace the components that may cause the fault, and then compare the fault phenomena before and after the replacement to determine or eliminate the judgment.

（3）试探法。改变某些系统的技术状态观察故障情况是否发生变化。

(3) Heuristics. Change the technical status of some systems and observe whether the fault condition changes.

（4）拆检法。对可能造成故障部位或部件拆卸检查，分析产生故障的具体原因。

(4) Disassembly and inspection method. Disassemble and inspect the parts or components that may cause the fault, and analyze the specific causes of the fault.

故障的防范建议

Fault prevention suggestions

除了每日的巡检以外，还要对机组的参数进行检测，检查机组水温及机组负荷是否正常一旦发生无法满负荷运行的现象，必须及时进行原因分析，排查进气系统是否存在堵塞现象，并对计量阀旁通阀等进行检测，根据运行参数合理进行检测与判断如机组负荷超范围摆动，应检查此现象是否由单缸或多缸的点火存在问题引起的，及时发现安全隐患并予以合理解决。

In addition to daily patrol inspection, the parameters of the unit shall also be inspected to check whether the water temperature and load of the unit are normal. Once the phenomenon that the unit cannot operate at full load occurs, the cause analysis must be carried out in time to check whether the air intake system is blocked, and the bypass valve of the metering valve shall be inspected. The detection and judgment shall be carried out reasonably according to the operating parameters. If the unit load swings beyond the range, It is necessary to check whether this phenomenon is caused by the ignition problems of single cylinder or multi cylinder, and timely find out and reasonably solve the safety hazards.

机组能否正常運行取决于故障的排除与解决速度如果检修人员不了解机组结构及运行原理，故障排查时思想混乱，都会导致无法及时解决故障维修人员应对常见的故障及发生原因进行分析与汇总，明确具体的诊断方法及解决方案，及早解决故障，减少故障机组的停机时间。

The normal operation of the unit depends on the speed of troubleshooting and solution. If the maintenance personnel do not understand the structure and operation principle of the unit and have confused thoughts during troubleshooting, they will not be able to solve the fault in time. The maintenance personnel shall analyze and summarize the common faults and their causes, identify the specific diagnosis methods and solutions, solve the faults as soon as possible and reduce the downtime of the faulty unit.

机组运行每超过一千小时必须进行保养对气门间隙以及过桥进行调整，清洗曲轴箱的呼吸器，及时进行充电机及皮带的检查，检测各个水泵水油管路系统及排气系统，还要对电气系统进行保养，及时发现安全隐患。

The unit must be maintained every 1000 hours of operation, the valve clearance and the bridge must be adjusted, the respirator of the crankcase should be cleaned, the charger and belt should be inspected in time, the water and oil pipeline system and exhaust system of each water pump should be tested, and the electrical system should be maintained to find out the potential safety hazards in time.

只有对燃气发电机常见的故障即产生的原因做到全面深入了解，一旦机组出现故障能够快速查明原因并及时排除才能保证机组的正常运行。您有问题或者需求就来我们网站//www.gz-yanye.com咨询查看了解吧！
