大型焦化发电机组错误操作会严重影响焦化发电机组运用寿命，关于焦化发电机组的一些常见错误操作就让小编来讲讲吧。

The wrong operation of large coking generator unit will seriously affect the service life of coking generator unit. Let's talk about some common wrong operations of coking generator unit.

1、焦化发电机在机油缺乏时运

1. Coking generator operates in case of oil shortage

焦化发电机在机油缺乏时运转，会因机油供给缺乏而构成各摩擦副表面供油缺乏，招致异常磨损或烧伤。因此，焦化发电机起步前和焦化机运转过程中要保证机油充足，防止由于缺油而惹起拉缸、烧瓦缺点。发电机组保养

When the coking generator runs in the absence of engine oil, the lack of engine oil supply will cause the lack of oil supply on the friction pair surfaces, resulting in abnormal wear or burns. Therefore, before starting the coking generator and during the operation of the coking machine, it is necessary to ensure that the oil is sufficient to prevent cylinder scuffing and bush burning due to lack of oil.

2、带负荷急停机或突然卸除负荷后立刻停机

2. Emergency shutdown with load or immediate shutdown after sudden load removal

焦化机发电机熄火后冷却系水的循环中止，散热才干急剧降低，受热件失去冷却，易构成气缸盖、气缸套、气缸体等机件过热，产生裂纹，或使活塞过度收缩卡死在缸套内。另一方面，焦化发电机停机时未经怠速降温，会使摩擦面含油缺乏，当焦化机再次启动时会因润滑不良而加剧磨损。因此，焦化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 coker generator is shut down, the circulation of cooling water stops, the ability to dissipate heat decreases sharply, and the heated parts lose their cooling, which is easy to cause overheating of cylinder head, cylinder liner, cylinder block and other parts, resulting in cracks, or make the piston shrink excessively and get stuck in the cylinder liner. On the other hand, when the coking generator is shut down without cooling at idle speed, the friction surface will be lack of oil. When the coking machine is started again, the wear will be aggravated due to poor lubrication. Therefore, the load of the coking generator shall be removed before the shutdown, and the speed shall be gradually reduced and the generator shall run for several minutes without load.

3、焦化发电机冷机启动

3. Coking generator chiller start

焦化发电机冷机启动时由于机油黏度大、活动性差，是机油泵供油缺乏，机器摩擦面因缺油润滑不良，构成急剧磨损，以致发作拉缸、烧瓦等缺点。因此，焦化机冷却启动后应怠速运转升温，待机油温度抵达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 cold engine of the coking generator starts, due to the high viscosity and poor mobility of the oil, it is the lack of oil supply from the oil pump, and the lack of oil and poor lubrication on the friction surface of the machine, resulting in sharp wear, which leads to cylinder scuffing, bush burning and other defects. Therefore, the coker shall be operated at idle speed and heated up after cooling and starting, and then operated with load when the oil temperature reaches above 40 ℃; When starting, the machine should be put into low gear and driven for a certain mileage at each gear in sequence until the oil temperature is normal and the oil supply is sufficient.

4、焦化机冷启动后猛轰油门

4. After cold start of coking machine, slam the accelerator

若猛轰油门，则焦化发电机转速急剧升高，会构成机上的有些摩擦面因产生干摩擦而猛烈磨损。另外，轰油门时活塞、连杆和曲轴受理力变化大，惹起猛烈撞击，易损坏机件。

If the accelerator is slammed, the speed of the coking generator will rise sharply, and some friction surfaces on the machine will be severely worn due to dry friction. In addition, the acceptance force of the piston, connecting rod and crankshaft changes greatly when the accelerator is slammed, causing violent impact and easy to damage the parts.

此外要知道焦化发电机过热还会恶化焦化机熄灭过程，使喷油器工作失常，雾化不良，积炭增加，要避免此问题的出现，更多相关事项就来我们的网站//www.gz-yanye.com咨询吧！

In addition, it should be known that overheating of the coking generator will also worsen the quenching process of the coking machine, resulting in abnormal operation of the fuel injector, poor atomization, and increased carbon deposition.
