瓦斯發(fā)電機組使用中要注意什么?
瓦斯發(fā)電機組應嚴格按瓦斯發(fā)電機組操作程序,使用清洗、呈堿性的清潔的軟化水做冷卻水,以免氣缸蓋水腔內沉積水垢、泥沙等污物,影響冷卻效果,甚至造成氣缸蓋裂痕。應通過(guò)驗查與調節氣門(mén)間隙,領(lǐng)悟、柴油機維修掌握各氣缸進(jìn)、排氣門(mén)的損傷、下陷情況。
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(huán)境下啟動(dòng)發(fā)電機組時(shí),要先將發(fā)電機組冷卻水和機油加熱至20℃以上。另外,瓦斯發(fā)電機組啟動(dòng)前應人力盤(pán)轉主軸12周,無(wú)異樣狀況后方可起動(dòng)。使用過(guò)程中怠速運轉時(shí)間不宣過(guò)長(cháng)。因為發(fā)電機組長(cháng)久低溫怠速運轉時(shí),機油會(huì )產(chǎn)生一種膠狀物附著(zhù)在氣門(mén)與氣門(mén)導管壁上,使氣門(mén)運動(dòng)受阻,停車(chē)后氣門(mén)往往被粘住,此時(shí)若再起動(dòng)發(fā)電機組,氣門(mén)系統就要出事故。這種現象在氣溫低或機油質(zhì)量較差時(shí)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(fā)電機組有缸蓋罩殼,進(jìn)行檢查:如個(gè)別汽缸工作異?;騽傂蘩?、更換過(guò)汽缸蓋,也應打開(kāi)缸蓋罩殼,進(jìn)行驗看:作業(yè)正常的汽缸通常無(wú)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(fā)電機組發(fā)電機組起動(dòng)前預供油時(shí),打開(kāi)氣缸蓋上罩殼,觀(guān)察搖臂襯套處是否有機油流出。若發(fā)現不上油時(shí),應立即拆檢。觀(guān)察缸蓋下罩殼內機油積存量的大小,正常時(shí)不應有積存,如有,說(shuō)明缸蓋回油道堵塞,應及時(shí)清理,保持回油道暢通。具體可驗看:瓦斯發(fā)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(fā)電機組的維保也很重要,只有對瓦斯發(fā)電機組的維護和維護到位,瓦斯發(fā)電機組才能很好的正常作業(yè),而且一個(gè)好的維修維保是確保瓦斯發(fā)電機組長(cháng)壽的關(guān)鍵,那么怎樣來(lái)進(jìn)行瓦斯發(fā)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(fā)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(zhì)上面,下面或周?chē)?/div>
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(fā)電機組清洗,工業(yè)用水溶濟來(lái)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(zhì)的保護有被撕裂或刺穿時(shí),需馬上更換以避免液體或油類(lèi)滲入積聚在物質(zhì)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(wǎng)未停電,其市網(wǎng)電源與自備發(fā)電機電源出現非同期并聯(lián),必毀壞機組。若自備發(fā)電機功率較大,還會(huì )使市網(wǎng)出現震蕩。 b) 市網(wǎng)已停電正在檢驗,其自備發(fā)電機倒送電。則會(huì )使供電部門(mén)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.
