The powerful Nd∶YAG laser was used to harden the surface of prison ring groove of nodular iron,the width of piston ring groove only was 4mm,the width of hardening layer should be 5~7mm,the methods of single scanning and tilted irradiation was used.

使用大功率Nd∶YAG激光,对模拟球墨铸铁活塞环槽的试样进行了表面相变硬化,试样环槽的宽度只有4mm,硬化层宽度要求达到5~7mm,采用了单道扫描和斜入射的工艺方法,最终得到了符合要求的硬化层形貌和指标。

The abrasion between the locomotive engine piston ring groove and piston ring is one of the mostly abrasion in the firebox of locomotive engine.

本文针对这一状况,选用了表面淬火、盐浴软氮化、阴极弧表面生成TiN薄膜手段,对活塞环槽表面进行强化耐磨处理,并利用等离子硫化的手段对活塞环进行处理,从中选择最优的方式来改善活塞环槽表面磨损状况。

The grooves into which they fit are called ring grooves.

安装活塞环的凹槽称为活塞环槽。

Most pistons have three ring grooves at the top.

大多数活塞的顶部有3个活塞环槽。

"Sometimes, all that is required is to free up the rings in the ring grooves by cleaning out carbon."

有时,所要做的仅仅是清除积碳,使活塞环在活塞环槽中活动自如。

Be sure that you do not remove metal when cleaning ring grooves or oil slots.

清洁活塞环槽或油环开缝,绝对不能损伤金属部分。

"Thus, piston rings must be used to provide the necessary seal. The rings are installed in grooves in the piston. Actually, there are two types of rings, compression rings and oil-control rings."

所以活塞环就用来提供必要的密封。活塞环装在活塞的凹槽中。事实上有两种活塞环,气环和油环。

Piston Ring Groove Depth – #1&2

活塞环凹槽深度– #1&2

) The inside surface of the ring fits in the groove on the piston.

)些环的内表面和活塞上的凹槽相配合。

In simplest terms, piston rings are thin, circular pieces of metal that fit into grooves in the tops of the pistons.

简单地讲，活塞环就是装在活塞顶部的凹槽里的薄，圆的金属。

"Then, when pressure is applied to the tool handles, the ring is sprung enough that it can be lifted out of the ring groove and off the piston sprung enough that it can be lifted out of the ring groove and off the piston."

然后用力压住工具手柄,使活塞环足以弹起,即可使之从环槽中脱出,而将其从活塞上取下。

The rings have joints (they are split) so that they can be expanded and slipped over the piston head and into the recessed grooves cut in the piston.

活塞环有接口(也就是有一缝隙)．这样可以使端部扩张并滑人活塞上的凹槽中。
