天然氣發電機組活塞與氣缸

D88尊龙  天然氣發電機組活塞要用優質的。一些廠家生產的劣質活塞裝上天然氣發電機組后會出現各種各樣的故障,不能正常使用。比如說有一種進口牌號的活塞裝上柴油機后不久,活塞的形狀就發生變化,無法再繼續使用下去。活塞質量的劣質從感官上一般不好判斷,建議使用正規廠家的產品。

  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.

D88尊龙  眾所周知,缸套有一般干式缸套和濕式缸套兩種,現在多數柴油機缸體用的是干式缸套。雖然,康明斯6BT 柴油機缸體所鑲的也是干式缸套,但它不是像傳統的那樣拉出舊缸套后壓入新缸套就行了,而是要先按規定尺寸鏜缸體底孔并留下止口,然后采取下述工藝壓裝:

  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:

  如果壓裝氣缸套時不采取上述工藝,而是先按規定尺寸鏜好缸體底孔后直接把氣缸套壓入,結果造成氣缸套不同程度地縮變,有一些天然氣發電機組使用后不久氣缸套就在缸體底孔內串動,致使氣缸套和缸體底孔之間形成間隙并導致柴油機冷卻不良。當然,這也是造成康明斯6BT 柴油機按傳統方法大修后,3萬km以內就出現缸體早期異常磨損的主要原因之一。

D88尊龙  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.

D88尊龙  換缸體時應注意的問題。市場上康明斯6BT柴油機的缸體也有偽劣產品,更換缸體時一定要注意。雖然無法從材質上判斷其質量優劣,但是可以通過測量其氣缸筒和凸輪軸座孔等有關孔徑的形狀公差是否符合要求來判斷其質量是否合格。

  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.
