The gas generator unit should strictly follow the operating procedures of the gas generator unit, using clean, alkaline, and softened water as cooling water to avoid the deposition of scale, sediment, and other contaminants in the water chamber of the cylinder head, affecting the cooling effect, and even causing cracks in the cylinder head. Through inspection and adjustment of valve clearance, it is necessary to understand and master the damage and subsidence of intake and exhaust valves of each cylinder through diesel engine maintenance.

低温环境下启动发电机组时，要先将发电机组冷却水和机油加热至20℃以上。另外，瓦斯发电机组启动前应人力盘转主轴12周，无异样状况后方可起动。使用过程中怠速运转时间不宣过长。因为发电机组长久低温怠速运转时，机油会产生一种胶状物附着在气门与气门导管壁上，使气门运动受阻，停车后气门往往被粘住，此时若再起动发电机组，气门系统就要出事故。这种现象在气温低或机油质量较差时易出现。

When starting a generator set in a low temperature environment, it is necessary to first heat the cooling water and oil of the generator set to above 20 ℃. In addition, before starting the gas generator unit, the main shaft should be manually rotated for 12 cycles, and it can only be started if there are no abnormal conditions. The idle running time should not be too long during use. "When the generator set operates at low temperature and idle speed for a long time, the engine oil will produce a colloidal substance that adheres to the valve and valve guide wall, blocking the movement of the valve. After parking, the valve is often stuck. At this time, if the generator set is restarted, the valve system will have an accident.". This phenomenon is prone to occur when the air temperature is low or the oil quality is poor.

瓦斯发电机组有缸盖罩壳，进行检查：如个别汽缸工作异常或刚修理、更换过汽缸盖，也应打开缸盖罩壳，进行验看：作业正常的汽缸通常无需此项察看。

The gas generator set has a cylinder head cover, which should be inspected: If individual cylinders work abnormally or have just been repaired or replaced, the cylinder head cover should also be opened for inspection: cylinders that operate normally do not usually require this inspection.

瓦斯发电机组发电机组起动前预供油时，打开气缸盖上罩壳，观察摇臂衬套处是否有机油流出。若发现不上油时，应立即拆检。观察缸盖下罩壳内机油积存量的大小，正常时不应有积存，如有，说明缸盖回油道堵塞，应及时清理，保持回油道畅通。具体可验看：瓦斯发电机组对气体的要求以及运行指南。

When pre supplying oil before starting the gas generator set, open the upper cover of the cylinder head and observe whether there is oil flowing out at the rocker arm bushing. If it is found that the oil is not applied, it should be immediately disassembled for inspection. Observe the amount of oil accumulated in the lower cover of the cylinder head. Normally, there should be no accumulation. If there is any, it indicates that the oil return passage of the cylinder head is blocked, and it should be cleaned in a timely manner to keep the oil return passage unblocked. For details, please refer to the requirements for gas in gas generating units and professional guidelines for operation.

瓦斯发电机组的维保也很重要，只有对瓦斯发电机组的维护和维护到位，瓦斯发电机组才能很好的正常作业，而且一个好的维修维保是确保瓦斯发电机组长寿的关键，那么怎样来进行瓦斯发电机组的保养维保呢。

The maintenance of gas generator units is also very important. Only when the maintenance and repair of gas generator units are in place can the gas generator units operate well and normally. Moreover, a good maintenance and repair is the key to ensuring the longevity of gas generator units. So how to carry out the maintenance and repair of gas generator units.

1、首先瓦斯发电机组应保持清洗，不可让液体，例如燃油或润滑油积在内或外的任何表面，也不可在任何吸音的物质上面，下面或周围。

1. First of all, the gas generator unit should be kept clean, and liquids such as fuel or lubricating oil should not accumulate on any surface inside or outside, nor on, under, or around any sound absorbing material.

2、瓦斯发电机组清洗，工业用水溶济来清洗机器的表面，不可用可燃性的溶液作清洗用，如吸音物质的保护有被撕裂或刺穿时，需马上更换以避免液体或油类渗入积聚在物质上。

2. For the cleaning of gas generator sets, industrial water is used to clean the surface of the machine. Combustible solutions cannot be used for cleaning. If the protection of sound-absorbing substances is torn or punctured, it is necessary to immediately replace them to prevent liquid or oil from seeping into and accumulating on the substances.

答：a) 市网未停电，其市网电源与自备发电机电源出现非同期并联，必毁坏机组。若自备发电机功率较大，还会使市网出现震荡。 b) 市网已停电正在检验，其自备发电机倒送电。则会使供电部门检修人员触电身亡。

Answer: a) The power supply of the municipal network is not powered off, and there is asynchronous parallel connection between the municipal network power supply and the self-contained generator power supply, which will inevitably damage the unit. If the power of the self-provided generator is large, it will also cause fluctuations in the urban network. b) The municipal power grid has been cut off and is undergoing inspection, with its own generator being switched on. It may cause electric shock to the maintenance personnel of the power supply department.
