活塞头

Often the displacer piston head itself acts as a low efficiency regenerator without any additional design features.

往往置换活塞头本身作为一个低效率的再生没有任何额外的设计特点。

The piston pin fits through one side of the piston, through the small end of the rod, and then through the other side of the piston.

活塞销贯穿活塞，把连杆小头与活塞连在一起，并将连杆保持在活塞中心的适当位置处。

This paper gives the repairing technology of processing to retread piston head including the repairing course and items to pay attention by analizing the causes leading to the main engine damaged.

文章通过对一起船舶主机机损事故的原因分析，阐明了活塞头翻新后机加工的修理工艺和注意事项，并详尽介绍了机损事故的修复过程，可供同行参考。

Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder.

因为液压是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。

When the pressure is low, the role of Poppet head pressure sufficient to overcome the pressure regulator spring force, Poppet Head is closed at this time there is no pressure on the oil through the damping holes on the balance of the piston movement, so a balance piston, the next two cavity pressure equal, balanced piston under the action of the spring force gently on the top of the seat, pressure port and overflow port unreasonable.

当压力较低时，作用在提动头上的压力不足以克服调压弹簧力，提动头处于关闭状态，此时没有压力油通过平衡活塞上的阻尼孔流动，故平衡活塞上、下两腔压力相等，平衡活塞在弹簧力的作用下轻轻地顶在阀座上，压力口和溢流口不通。

When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.

当流经平衡活塞上阻尼孔的流量增加时，平衡活塞上、下两侧的压差增加，平衡活塞上升距离增加，反之则减小；又因为弹簧的刚度很小，使平衡活塞上移所需压差变化很小，所以通过提动头的流量变化也不大，因此提动头的开口变化很小，提动头开启的压力可以说是不变的，亦即当先导阀的弹簧一经设定后，提动头被打开时的平衡活塞上腔的压力基本保持不变。

The connecting rod main part processes a surface being that head hole and both ends big or small are weak, more important faying face and bolt hole locating surface being the connecting rod body and cover treating /outside.

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
