The machine is used for hydraulic leak testing of rails for diesel injection in combustion engines.
There are two test stations available. The loading and unloading is done manually, the test sequence automatically.
Two different rail types are checked. The mechanical changeover is easy to implement by exchange of pallets.
The test is performed in alternation, so that loading and unloading are not significant.
After the start of the test sequence, depending on the type, there is a pressure drop test of rails with air (check the sealing element of a valve).
After a positive test, the rail is hydraulically filled and flushed.
Subsequently, the pressure increases up to 3000bar and after a defined measurement time, the gradient of the pressure drop is
determined and evaluated. After the test, the rail is drained and blown out before the unload follows by the operator.
Highlights
- Short changeover time with interchangeable devices (2 per rail type)
- Hydraulic pressure drop test to 3000bar
- Integration of the hydraulic unit into the machine (to save space)
- Windows-based PC user interface for machine control and process parameterization
- Graphical representation of all analog signals
- Full data communication to customer production server
Technical data
- Hydraulical purge pressure up to 200bar
- Hydraulical test pressure up to 3000bar
- Pneumatic leak test up to 10bar
