受制于气源及使用环境的变化瓦斯发电机出现故障

返回 2022.06.20 来源:http://www.huannengpower.com
瓦斯发电机组系统是集气体-热力-机械-电气为一体的设备整体,利用煤矿的废弃瓦斯进行发电,不但可以变废为宝,满足煤矿的部分用电要求,还可以减少温室气体的排放,提升煤矿井下的安全系数。但是,受制于气源以及使用环境的变化,瓦斯发电机在使用过程中经常会出现故障,这些故障主要可分为:
The gas generator set system is a whole set of equipment integrating gas, heat, machinery and electricity. Using the waste gas of the coal mine for power generation can not only turn waste into treasure, meet some power requirements of the coal mine, but also reduce greenhouse gas emissions and improve the safety factor of the coal mine. However, subject to the changes of gas source and operating environment, gas generators often have faults during operation. These faults can be mainly 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 gas leakage of the transmission pipeline. 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 fault: the unit fault mainly includes the damage of unit body parts. Such as oil leakage of lubrication system, damage of 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 failure, low voltage, poor connection of secondary line, 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,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。本发明针对机组故障中常见的启动故障,设计了一种多特征量采集系统,配合判据理论,实现对发电机组启动故障的的诊断。
Among the above three types of faults, the unit fault is particularly prominent, accounting for about 70% of the total faults, and the consequences are serious after the fault occurs. Therefore, the real-time monitoring of the unit fault is of great significance to the early warning of the fault. The invention designs a multi characteristic quantity acquisition system for common startup faults in unit faults, and realizes the diagnosis of generator unit startup faults in cooperation with the criterion theory.
瓦斯发电机组
瓦斯发电机组厂家认为启动系统故障主要由以下原因造成:
The manufacturer of gas generator set believes that the starting system fault 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. 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. After a period of operation, the solenoid valve cannot be started due to poor contact caused by oxidation of wires or terminals;
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 compressed air pressure is normal, and whether there is water, impurities and dirt in the air screen, which causes 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 sliding block edge in the air distributor is easy to be worn, resulting in loose sealing and air leakage. At this time, the unit can not be started due to insufficient starting pressure.
