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.

低溫環境下啟動發電機組時，要先將發電機組冷卻水和機油加熱至20℃以上。另外，瓦斯發電機組啟動前應人力盤轉主軸12周，無異樣狀況后方可起動。使用過程中怠速運轉時間不宣過長。因為發電機組長久低溫怠速運轉時，機油會產生一種膠狀物附著在氣門與氣門導管壁上，使氣門運動受阻，停車后氣門往往被粘住，此時若再起動發電機組，氣門系統就要出事故。這種現象在氣溫低或機油質量較差時易出現。

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.

瓦斯發電機組有缸蓋罩殼，進行檢查：如個別汽缸工作異常或剛修理、更換過汽缸蓋，也應打開缸蓋罩殼，進行驗看：作業正常的汽缸通常無需此項察看。

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.

瓦斯發電機組發電機組起動前預供油時，打開氣缸蓋上罩殼，觀察搖臂襯套處是否有機油流出。若發現不上油時，應立即拆檢。觀察缸蓋下罩殼內機油積存量的大小，正常時不應有積存，如有，說明缸蓋回油道堵塞，應及時清理，保持回油道暢通。具體可驗看：瓦斯發電機組對氣體的要求以及運行指南。

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.

瓦斯發電機組的維保也很重要，只有對瓦斯發電機組的維護和維護到位，瓦斯發電機組才能很好的正常作業，而且一個好的維修維保是確保瓦斯發電機組長壽的關鍵，那么怎樣來進行瓦斯發電機組的保養維保呢。

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、首先瓦斯發電機組應保持清洗，不可讓液體，例如燃油或潤滑油積在內或外的任何表面，也不可在任何吸音的物質上面，下面或周圍。

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、瓦斯發電機組清洗，工業用水溶濟來清洗機器的表面，不可用可燃性的溶液作清洗用，如吸音物質的保護有被撕裂或刺穿時，需馬上更換以避免液體或油類滲入積聚在物質上。

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) 市網未停電，其市網電源與自備發電機電源出現非同期并聯，必毀壞機組。若自備發電機功率較大，還會使市網出現震蕩。 b) 市網已停電正在檢驗，其自備發電機倒送電。則會使供電部門檢修人員觸電身亡。

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.
