天然气发电机组活塞与气缸

  天然气发电机组活塞要用优质的。一些厂家生产的劣质活塞装上天然气发电机组后会出现各种各样的故障,不能正常使用。比如说有一种进口牌号的活塞装上柴油机后不久,活塞的形状就发生变化,无法再继续使用下去。活塞质量的劣质从感官上一般不好判断,建议使用正规厂家的产品。

  Gas generator set,The piston with high quality. Some inferior piston manufacturer production on all kinds of fault will be shown after the natural gas generator set, can't normal use. Such as a kind of imported brands on diesel engine piston, shortly after the shape of the piston is changing, unable to continue to use. Piston quality inferior generally bad judgment from the senses, it is recommended to use normal manufacturer brand products.

  众所周知,缸套有一般干式缸套和湿式缸套两种,现在多数柴油机缸体用的是干式缸套。虽然,康明斯6BT 柴油机缸体所镶的也是干式缸套,但它不是像传统的那样拉出旧缸套后压入新缸套就行了,而是要先按规定尺寸镗缸体底孔并留下止口,然后采取下述工艺压装:

  As is known to all, cylinder liner is generally dry cylinder liner and wet cylinder liner, now most of the diesel engine cylinder block using dry cylinder liner. Although, cummins 6 bt diesel engine cylinder block set is also dry cylinder liner, but it is not like the traditional pull out after the old cylinder pressure into the new cylinder liner went, but to first base hole boring cylinder size according to the rules and leave seam allowance, and then take the following process being connected:

  如果压装气缸套时不采取上述工艺,而是先按规定尺寸镗好缸体底孔后直接把气缸套压入,结果造成气缸套不同程度地缩变,有一些天然气发电机组使用后不久气缸套就在缸体底孔内串动,致使气缸套和缸体底孔之间形成间隙并导致柴油机冷却不良。当然,这也是造成康明斯6BT 柴油机按传统方法大修后,3万km以内就出现缸体早期异常磨损的主要原因之一。

  If you do not take the above process when pressed cylinder liner, but a good boring cylinder body bottom hole size according to the rules before the cylinder casing pressure directly into, resulting in cylinder liner shrinkage change in different degrees, there are some natural gas generator set using cylinder liner inside the cylinder bottom intake string shortly after, the gap formed between cylinder liner and the cylinder bottom intake and leads to poor diesel engine cooling. , of course, this is also caused by cummins 6 bt diesel engine according to the traditional method for overhaul, within 30000 km is one of the main causes of early abnormal wear of cylinder body.

  换缸体时应注意的问题。市场上康明斯6BT柴油机的缸体也有伪劣产品,更换缸体时一定要注意。虽然无法从材质上判断其质量优劣,但是可以通过测量其气缸筒和凸轮轴座孔等有关孔径的形状公差是否符合要求来判断其质量是否合格。

  Problems that should be paid attention to when change the cylinder body. On the market of cummins 6 bt diesel engine cylinder body are false and inferior product, replacing cylinder must pay attention to. Although unable to judge its quality from the material, but can be by measuring the cylinder barrel and camshaft hole and the shape of the aperture of tolerance is in line with the requirements to determine whether the quality qualified.
