使用天燃气发电机组应该注意什么呢?

正值冬季,天气气温低,在使用天然气发电机组的时候容易出现机组汽缸盖易裂缝漏水的故障,其主要原因时什么?在冬季用户使用天然气发电机组的时候应该怎样预防气缸的开裂呢?
It is winter and the weather and temperature are low. When using the natural gas generator unit, it is easy to crack and leak the cylinder head of the unit. What are the main reasons? How to prevent cylinder cracking when users use natural gas generator sets in winter?
1.天然气发电机组运转时,冷却水不足或水箱开锅机温过高,突然加入冷却水。
1. When the natural gas generator unit is running, the cooling water is insufficient or the boiling machine temperature in the water tank is too high, and the cooling water is suddenly added.
2.起动后我们才加入冷却水,天然气发电机组起动后,机内的温度就会越来越高,如果这时加入冷却水,汽缸体与汽缸盖急剧冷却,就会因冷缩而裂缝。
2. We only add cooling water after starting. After the natural gas generator set is started, the temperature in the machine will be higher and higher. If cooling water is added at this time, the cylinder block and cylinder head will cool sharply, and cracks will be caused by cold shrinkage.
3.天然气发电机组长时间运转,机内温度高,停车后立即放掉高温水。会导致高温零件骤遇冷空气而开裂。
3. The natural gas generator runs for a long time and the temperature in the generator is high. Drain the high-temperature water immediately after shutdown. It will cause high-temperature parts to crack suddenly when encountering cold air.
4.停机后,没有放冷却水。机内水冻结成冰,体积增大,发生汽缸体和汽缸盖胀裂。
4. No cooling water was discharged after shutdown. The water in the machine freezes into ice, the volume increases, and the cylinder block and cylinder head expand and crack.
5.使用减压机停机,使高温的气缸盖突然遇到寒冷空气而导致开裂。
5. Shut down the pressure reducer to make the high-temperature cylinder head suddenly encounter cold air and cause cracking.
防止各类汽缸体和汽缸盖开裂有以下方法:
There are the following methods to prevent cracking of various cylinder blocks and cylinder heads:
1.起动天然气发电机组前,应先给水箱加入温热水,严冬季节要灌注热水2~3次,待放水阀中流出的水约30~50℃时起动为佳。
1. Before starting the natural gas generator set, warm hot water shall be added to the water tank. In severe winter, hot water shall be injected 2 ~ 3 times. It is better to start when the water flowing out of the drain valve is about 30 ~ 50 ℃.
2.发动机运转时间较长时,停机后应等待半个小时左右,机温下降到40~50℃时再放冷却水。放完水后用细铁丝捅通放水阀开关,防止沉淀物堵塞放水阀。
2. When the engine runs for a long time, wait for about half an hour after shutdown, and drain the cooling water when the engine temperature drops to 40 ~ 50 ℃. After draining, poke the drain valve switch with a fine iron wire to prevent sediment from blocking the drain valve.
3.天然气发电机组运转过热严重缺水时,应让柴油机低速空转10~15分钟,然后再慢慢加入冷却水。
3. When the natural gas generator set is overheated and seriously short of water, let the diesel engine idle at low speed for 10 ~ 15 minutes, and then slowly add cooling water.
