  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。
    1. When the natural gas generator set is running, the cooling water is insufficient or the temperature of the water tank boiler is too high, and the cooling water is suddenly added.
    2.起動后我們才加入冷卻水,天然氣發電機組起動后,機內的溫度就會越來越高,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。
    2. After starting, we add cooling water. After starting, the temperature in the machine will be higher and higher. If the cooling water is added, the cylinder block and cylinder head will be cooled sharply, and the cracks will be caused by cold shrinkage.
    D88尊龙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. the natural gas generator group operates for a long time with high temperature inside the machine and immediately releases high temperature water after parking. It will cause high temperature parts to crack in cold air.
    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。
    4. after shutdown, no cooling water was put on. The water inside the machine is frozen into ice, the volume increases, and the cylinder body and the cylinder head crack.
    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. use the pressure reducing machine to stop, causing the high temperature cylinder head to suddenly encounter cold air and cause cracking.
    防止各類汽缸體和汽缸蓋開裂有以下方法:
    To prevent cracking of various cylinder blocks and cylinder heads, the following methods are adopted:
    1.起動天然氣發電機組前,應先給水箱加入溫熱水,嚴冬季節要灌注熱水2~3次,待放水閥中流出的水約30~50℃時起動為佳。
    1. Before starting a natural gas generator set, warm water should be added to the water tank. In severe winter, hot water should be poured 2-3 times. Starting is preferable when the water from the drain valve is about 30-50 degrees Celsius.
    2.發動機運轉時間較長時,停機后應等待半個小時左右,機溫下降到40~50℃時再放冷卻水。放完水后好用細鐵絲捅通放水閥開關,防止沉淀物堵塞放水閥。
    2. When the engine runs for a long time, it should wait for about half an hour after shutdown, and then put the cooling water when the engine temperature drops to 40-50 degrees Celsius. After the water is put off, it is best to use the thin wire to poke through the drain valve switch to prevent the sediment from blocking the drain valve.
    3.天然氣發電機組運轉過熱嚴重缺水時,應讓柴油機低速空轉10~15分鐘,然后再慢慢加入冷卻水。
    D88尊龙3. When the natural gas generating set is running overheated and seriously short of water, the diesel engine should idle for 10-15 minutes at low speed, and then slowly add cooling water.
