发电机使用的过程中有那些误区是大家须避开的呢？如果操作不当又会引发哪些问题呢？关于上述两个问题瓦斯发电机组厂家将带大家详细的了解一下。

What are the misunderstandings we should avoid in the process of using the generator? What problems will be caused if the operation is improper? The manufacturer of gas generator set will give you a detailed understanding of the above two issues.

1、突然卸除负荷后立刻停机或带负荷急停机

1. Immediate shutdown or emergency shutdown with load after sudden unloading

发电机熄火后冷却系水的循环停止，散热能力急剧降低，受热件失去冷却，易造成气缸盖、气缸套、气缸体等机件过热，产生裂纹，或使活塞过度膨胀卡死在缸套内。另一方面，发电机停机时未经怠速降温，会使摩擦面含油不足，当机再次启动时会因润滑不良而加剧磨损。因此，发电机熄火前应卸除负荷，并逐渐降低转速、空载运转几分钟。

After the generator flameout, the circulation of cooling system water stops, the heat dissipation capacity decreases sharply, and the heating parts lose cooling, which is easy to cause the cylinder head, cylinder liner, cylinder block and other parts to overheat, produce cracks, or cause the piston to expand excessively and get stuck in the cylinder liner. On the other hand, if the generator is not cooled at idle speed when it is stopped, the oil content of the friction surface will be insufficient. When the generator is restarted, the wear will be aggravated due to poor lubrication. Therefore, before the generator flameout, the load shall be removed, and the speed shall be gradually reduced and the generator shall be operated for several minutes without load.

2、在冷却水量不足或冷却水、机油温度过高的情况下运转

2. Operate under the condition of insufficient cooling water or high temperature of cooling water and oil

发电机冷却水量不足会降低其冷却效果，机因得不到有效的冷却而过热；冷却水、机油的油温过高，也会引起机过热。此时发电机气缸盖、气缸套、活塞组件及气门等主要受热负荷大，其机械性能如强度、韧性等急剧下降，使零件变形增加，减小了零件间的配合间隙，加速机件磨损，严重时还会产生裂纹、机件卡住的故障。发电机过热还会恶化机燃烧过程，使喷油器工作失常，雾化不良，积炭增多。

Insufficient cooling water of the generator will reduce its cooling effect, and the machine will overheat due to lack of effective cooling; If the oil temperature of cooling water and engine oil is too high, the engine will also overheat. At this time, the main heating loads of the generator cylinder head, cylinder sleeve, piston assembly and valve are large, and their mechanical properties, such as strength and toughness, are sharply reduced, resulting in increased deformation of the parts, reduced the fit clearance between the parts, accelerated the wear of the parts, and in serious cases, cracks and stuck parts will also occur. Overheating of the generator will also worsen the combustion process of the engine, make the fuel injector work abnormally, atomize poorly, and accumulate more carbon.

3、机冷启动后猛轰油门

3. Bang the throttle after cold start

发电机冷启后若猛轰油门，则发电机转速急剧升高，会造成机上的有些摩擦面因产生干摩擦而剧烈磨损。另外，轰油门时活塞、连杆和曲轴受理力变化大，引起剧烈撞击，易损坏机件。

If the throttle is slammed after the cold start of the generator, the speed of the generator will rise sharply, which will cause severe wear of some friction surfaces on the generator due to dry friction. In addition, the acceptance force of piston, connecting rod and crankshaft changes greatly when the throttle is slammed, causing severe impact and easy to damage the parts.

4、冷启动后未暖机就带负荷运转

4. Operate with load without warming up after cold start

发电机冷机启动时，由于机油黏度大、流动性差，是机油泵供油不足，机器摩擦面因缺油润滑不良，造成急剧磨损，甚至发生拉缸、烧瓦等故障。因此，机冷却启动后应怠速运转升温，待机油温度达到40℃以上时再带负荷运转；机器起步应挂低速挡，并循序在每一挡位行驶一段里程，直到油温正常、供油充分后，方可转为正常行驶。

When the generator cold engine is started, due to the high viscosity and poor fluidity of the oil, the oil supply of the oil pump is insufficient, and the friction surface of the machine is badly lubricated due to the lack of oil, resulting in sharp wear, and even cylinder pulling, tile burning and other faults. Therefore, after the engine cools down and starts, it should run at idle speed and warm up, and then run with load when the oil temperature reaches above 40 ℃; The machine should be put into low gear when starting, and drive for a certain mileage in each gear in sequence until the oil temperature is normal and the oil supply is sufficient.

5、机在机油不足时运转

5. The engine runs when the oil is insufficient

此时会因机油供给不足而造成各摩擦副表面供油不足，导致异常磨损或烧伤。为此，发电机起步前和机运转过程中要保证机油充足，防止由于缺油而引起拉缸、烧瓦故障。

At this time, the oil supply on the surface of each friction pair will be insufficient due to insufficient oil supply, resulting in abnormal wear or burn. Therefore, before starting and during the operation of the generator, it is necessary to ensure that the engine oil is sufficient to prevent cylinder pulling and tile burning due to lack of oil.
