  天然气发电机组气缸开裂原因有哪些呢?下面小编为您讲解一下:

  What are the causes of cracking of natural gas generator sets? The following Xiaobian for you to explain:

  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。汽缸体和汽缸盖过冷收缩也会引起开裂。

  1, the operation of natural gas generating unit, cooling water shortage or boil water tank machine temperature is too high, sudden cooling water. The cylinder body and the cylinder cover are also caused by cold shrinkage cracking.

  2、起动后才加冷却水。天然气发电机组起动后,机内温度立即升高,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, after the start of cooling water. The starting of natural gas generating unit, the internal temperature increased immediately, if added to the cooling water, the cylinder body and the cylinder cover will be due to rapid cooling, cold shrink and crack.

  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, natural gas generator long time operation, high temperature inside the machine, let the hot water immediately after parking. The cold air will lead to high temperature parts and cracking.

  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, shutdown, no cooling water. The water is frozen into ice machine, the volume increased, occurrence of the cylinder block and cylinder head cracking.

  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, the use of pressure reducing machine shutdown, so that the high temperature cylinder head suddenly encountered cold air and lead to cracking.
