  天然氣發電機組氣缸開裂原因有哪些呢?下面小編為您講解一下:

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

  1、天然氣發電機組運轉時,冷卻水不足或水箱開鍋機溫過高,突然加入冷卻水。汽缸體和汽缸蓋過冷收縮也會引起開裂。

D88尊龙  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、起動后才加冷卻水。天然氣發電機組起動后,機內溫度立即升高,如果這時加入冷卻水,汽缸體與汽缸蓋急劇冷卻,就會因冷縮而裂縫。

D88尊龙  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、天然氣發電機組長時間運轉,機內溫度高,停車后立即放掉高溫水。會導致高溫零件驟遇冷空氣而開裂。

  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、停機后,沒有放冷卻水。機內水凍結成冰,體積增大,發生汽缸體和汽缸蓋脹裂。

D88尊龙  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、使用減壓機停機,使高溫的氣缸蓋突然遇到寒冷空氣而導致開裂。

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