氦气填充的压力减震器的密封检测台

 

为了供油管内的压力脉冲减震,椭圆形管道内填加了氦气。这种压力减震器的成分最终检测就是密封检测。

此密封检测台做为半自动化机器配有4组件的圆形转台。由操作者手动上料。零件放置后通过双手同时操作开始自动化检测。借助一个粗略密封检测工位,零件被预选,这样能避免造成泄漏探测器UL200不必要的污染。然后在同一个检测工位上接着检测压力减震器的泄漏。一个气动的升降铸印机标注所有检测合格的零件。

 

供油管的氦气密封检测台

 

供油管所有组装件在完成组装后会做一个氦气密封检测。氦气通过氦气探测器可查明管的密封性。为了保持较低的氦气损耗,重新获得尽可能多的检测所需的氦气。检测台可产生210bar的最大氦气压力。为了尽可能保证高安全性,检测台可自身借助一个校准件检测功能性。检测台会持续被抽吸,为了排除受污染的氦气,避免测量错误。在检测结束后,检测件只要在允许的误差范围内,都会做标记。

 

Helium Leakage Test of GDI Pumps

This machine is used for leak verification with helium gas of laser welded fuel pump units.
The work piece will be put into one of the 6 pump carriers of the rotary table (3 carriers for each pump type) and following automatically moved into the leak test station.
First, the pump unit will be identified by reading the data matrix code. After this, a gross leak test will be performed, in order to sort out early enough parts with obvious manufacturing faults. Following the helium leak test will be done. If this is finished and after turning the rotary table again, the tested part can be taken out of the machine by the operator. He puts it to the right place according the test status. The discard of a failed part is verified by the machine.
It is possible to run two mechanically different pump types. The change-over for this is done automatically after selecting it in the user software. It is not needed to do any mechanical modification for this.


 

密封检测台

此检测台用于激光焊接后波纹管部件的密封检测。除此之外还可以确定波纹管长度和弹性率。此部件输送到机器的工作台上,在那自动分隔成6块,放置在配有双工件槽的转盘上。接下来波纹管会做一个粗略密封检测以便零件预先做一个产品错误整理。在接下来用氦气做一个精准密封检测。最后波纹管长度和弹性率会被控制,在零件从转盘上取出之前。并按照检测结果放置到合格与不合格件箱中。

Helium Leak Test Machine

The test bench is used for helium leak verification of laser welded metal bellows. It is also possible to compress and strain bellows for adjusting the correct length. Different bellow types can be tested/adjusted. The parameter change-over is simply done by selecting the type in the user software. 
Leak test station:
The work piece will be loaded manually into one of 4 fixtures (two double stations). First, a gross leak test will be performed in order to sort out parts with obvious manufacturing faults. Afterwards the helium leak test will be done.
Compression station:
Up to 4 bellows can be loaded manually into the station. The parts will be compressed and strained in order to achieve the final length. If necessary, this cycle can be repeated several times automatically by parameter setup.
