判断燃气发电机组故障有三种方式:

There are three ways to judge a gas turbine fault:

天然气发电机组故障的时候,要注意自行诊断。一方面看天然气发电机组的故障范围,一方面究其原因,因症施治。不可能设计出一种自诊断系统对其所有可能产生的故障都能进行诊断,因此,以直观诊断方法为主进行检查和判断的工作在任何时候对任何系统来说,都是不可替代的。通过看、听、试等方式掌握天然气发电机组的故障特点。

Pay attention to self diagnosis when the gas generator sets are out of order. On the one hand, the fault scope of natural gas generator sets is investigated. On the one hand, the reasons are discussed. It is impossible to create a diagnosis, self diagnosis system can all of its possible fault so the inspection and judgment in an intuitive diagnosis method based work at any time on any system, are irreplaceable. Mastering the fault characteristics of natural gas generator sets by means of watching, listening and testing.

1、看:看天然气发电机组系统类型、机型等等,判断具体的故障根源。检查真空软管是否老化、破裂或挤坏,并检查真空软管经过的途径和接头是否良好。检查控系统线束的连接状况,如传感器、执行器的电器是否良好,线束间的连接是否松动或断开,电线是否有磨破或线间短路现象,电连接器的插头和插座有无腐蚀现象等。

1: look at the natural gas generator system type, type, etc., to determine the specific root cause of the failure. Check whether the vacuum hose is aging, broken or squeezed, and check the way the vacuum hose passes and whether the joint is good or not. Check the connection status of control system of wire harness, such as sensors and actuators of the electric wire harness is good, whether the connection between loose or broken wires are worn or short line, plug and socket connector has no corrosion phenomenon.

2、听:主要是听机组工作时的声音,有无爆震,有无敲缸,有无失速,各个不同部件的不同工作噪声有无异常等。这需要长期的经验累积才能准确判断。

2: Listen: mainly listen to the work of the unit when the sound, whether or not knock, whether knock cylinder, whether stall, different parts of the different work noise, such as abnormal. This requires long-term experience to accumulate to be able to judge accurately.

3、试:主要是根据前述检查,有针对性的试机,以便进异步确定故障。

3, test: mainly in accordance with the foregoing inspection, targeted testing machine, in order to enter the asynchronous to determine the failure.
