实际上受制于气源以及使用环境的变化，瓦斯发电机组在使用过程中经常会出现故障，这些故障主要可分为：

In fact, due to the change of gas source and use environment, gas generator sets often have faults during use. These faults can be divided into:

1、气源故障：瓦斯气的浓度、流量过低,还有因瓦斯输送管道上气液分离器、干式阻火器堵塞造成气体流通不畅,输送管道漏气等,机组供气不足的现象统称为气源故障。

1. Gas source failure: the concentration and flow of gas are too low, the gas flow is blocked due to the blockage of gas-liquid separator and dry flame arrester on the gas transmission pipeline, and the transmission pipeline leaks. The phenomenon of insufficient gas supply of the unit is collectively referred to as gas source failure.

2、机组故障：机组故障主要包括机组本体零部件损坏。如润滑系统漏油、进气阀和排气阀损坏等。

2. Unit failure: the unit failure mainly includes the damage of the unit body parts. Such as oil leakage of the lubricating system, damage of the inlet valve and exhaust valve, etc.

3、电气故障：电气故障主要包括点火系统不点、电压低、二次线连接触不良、开关损坏等。

3. Electrical fault: electrical fault mainly includes ignition system spotless, low voltage, poor contact of secondary line connection, switch damage, etc.

在上述三类故障中，其中尤以机组故障尤为突出，其约占总体故障的70％左右，且发生故障后，导致的后果为严重。

Among the above three types of failures, the unit failure is particularly prominent, accounting for about 70% of the total failures, and the consequences caused by the failure are serious.

启动系统故障主要由以下原因造成：

The starting system failure is mainly caused by the following reasons:

1、启动电磁阀是否良好,电流、电压是否正常。由于电磁阀内接线空间较小,接线时很容易造成导线断线,又不易被发现,运行一段时间由于导线或端子氧化等造成接触不良,均会造成电磁阀无法启动；

1. Check whether the starting solenoid valve is in good condition and whether the current and voltage are normal. Due to the small wiring space in the solenoid valve, it is easy to cause wire breakage during wiring, and it is not easy to be found. The solenoid valve cannot be started due to poor contact caused by oxidation of wires or terminals during operation for a period of time;

2、压缩空气压力是否正常,空气屏内是否有积水和杂质、脏物造成主启动阀堵塞,无法开启；

2. Whether the pressure of compressed air is normal, and whether there is water, impurities and dirt in the air screen that cause the main starting valve to be blocked and cannot be opened;

3、空气分配器工作是否良好,由于机组运行时振动较大、油质较脏,空气分配器内滑块边缘易磨损,造成密封不严漏气,此时机组也会因启动压力不足,无法启动。

3. Whether the air distributor works well. Due to the large vibration and dirty oil during the operation of the unit, the edge of the sliding block in the air distributor is easy to wear, resulting in poor sealing and air leakage. At this time, the unit cannot be started due to insufficient starting pressure.

因此，针对机组故障的实时监测，对故障的预警具有重要意义。您只有提前多去了解多去做预防措施，才能让故障少出现，即便是出现了也能快速解决。关注我们http://www.huannengpower.com，了解更多！
