1. Causes of serious wear of cylinder liner of natural gas generator set

活塞在缸套內壁高速運動，不可避免地會造成缸套的磨損。若氣缸套在裝配時的位置誤差較大，或活塞環在裝配時不符合技術要求，氣缸套會很快出現嚴重磨損。

The high-speed movement of piston in the inner wall of cylinder liner will inevitably cause the wear of cylinder liner. If the position error of the cylinder liner is large during assembly, or the piston ring does not meet the technical requirements during assembly, the cylinder liner will be seriously worn soon.

2、氣缸套發生裂紋的原因

2. Causes of cylinder liner crack

如廠家在鑄造時存在缺陷，或是操作人員使用保養不當，在缸套外壁經過冷熱突變、長時間超負荷運轉或缸套外壁結冰時，都會造成缸套裂紋；若氣缸套裝配不正確，會造成氣缸套和氣缸體之間的配合間隙發生變化，導致氣缸套在氣缸體中產生歪斜現象。

If the manufacturer has defects in casting, or the operator does not use and maintain properly, the cylinder liner cracks will be caused when the outer wall of the cylinder liner goes through cold and hot mutation, long-time overload operation or the outer wall of the cylinder liner freezes; if the cylinder liner is not matched correctly, the matching gap between the cylinder liner and the cylinder block will change, resulting in the cylinder liner skew in the cylinder block.

 

3、天然氣好色先生在线观看氣缸套發生拉缸的原因

3. Causes of cylinder liner pulling of natural gas generator set

一般地，發生拉缸的原因有五種，一是活塞與氣缸套之間的間隙較小；二是磨合期的保養沒有按技術要求進行;三是裝配的活塞環切口間隙過小；四是潤滑油內固體顆粒較多；五是操作者在沒有潤滑油壓力或潤滑油壓力較低時，快速地提高柴油好色先生在线观看轉速。

Generally, there are five reasons for cylinder pulling: the first is that the clearance between piston and cylinder liner is small; the second is that the maintenance during running in period is not carried out according to the technical requirements; the third is that the clearance of piston ring notch is too small; the fourth is that there are more solid particles in lubricating oil; the fifth is that the operator can quickly increase the speed of diesel generator set when there is no lubricating oil pressure or the lubricating oil pressure is low.

4、氣缸套產生穴蝕的原因

4. Causes of cavitation erosion in cylinder liner

氣缸套發生穴蝕的原因一般有以下三種。一是廠家在鑄造時存在缺陷；二是缸套與活塞間的配合間隙過大；三是缸套與氣缸體之間的配合間隙過大。

There are three reasons for cavitation of cylinder liner. The first is that there are defects in casting; the second is that the fit clearance between cylinder liner and piston is too large; the third is that the fit clearance between cylinder liner and cylinder block is too large.

天然氣好色先生在线观看氣缸套易產生的故障

Trouble of cylinder liner of natural gas generator set

天然氣好色先生在线观看的氣缸套在長期的使用過程中，由於受到高溫高壓、冷卻液的穴蝕破壞和機械應力的作用，易產生嚴重磨損、裂紋、穴蝕和拉缸等故障。當氣缸套出現嚴重磨損後，會導致氣缸內部壓縮壓力下降、功率降低等。

During the long-term use of the cylinder liner of natural gas generator set, due to the high temperature and high pressure, cavitation damage of coolant and mechanical stress, it is easy to cause serious wear, crack, cavitation and cylinder pulling. When the cylinder liner is seriously worn, the compression pressure and power in the cylinder will decrease.

若用一字旋具在飛輪監視孔撥動柴油好色先生在线观看飛輪齒圈，還會昕見漏氣聲；缸套出現裂紋或穴蝕後，氣缸套可能會漏氣，油底殼內部潤滑油會進入冷卻液。如果裂紋或穴蝕位置在活塞上止點以上，柴油好色先生在线观看起動後還會出現水箱(或散熱器)向外反水的現象；柴油好色先生在线观看出現拉缸後的明顯特征是轉速下降、功率降低、潤滑油溫度升高和排煙增多等。

If you move the flywheel ring gear of diesel generator set with a straight bit in the flywheel monitoring hole, you will hear the sound of air leakage; after the cylinder liner cracks or cavitation, the cylinder liner may leak, and the lubricating oil in the oil pan will enter the coolant. If the crack or cavitation is located above the top dead center of the piston, the water tank (or radiator) will return to the outside after the start of the diesel generator set; the obvious characteristics of the diesel generator set after the cylinder pulling are the decrease of speed, the decrease of power, the increase of lubricating oil temperature and the increase of smoke exhaust.
