Impulse Test Rig: 1000 / 2000 Bar

Product Details

As in the high pressure range of up to 6,000 bar, the standard impulse test stands are also operated with a hydraulic pressure of 330 bar. This is produced by a hydraulic power unit and drives the pressure booster via a regulator valve. The pressure booster has a constant pressure ratio and produces high pressure through its linear movements. We also use high-dynamic servo-regulator valves for our standard systems, which guarantee a precise repeatability even at very high test frequencies.

The pressure control of the system is realized by means of a pressure transducer. The test medium is hydraulic oil. A perfectly-tuned cooling system keeps the temperature at the pressure booster and in the hydraulics in equilibrium. The cooling is realized by a very efficient water-cooling system.

In order to be able to assess the quality of the tests, the test pressure profile is measured by the pressure transducer already mentioned and is accordingly stored in the system as a data record. The visualization and evaluation of the test sequence is carried out via a PC. The operation is menu-driven and enables special software configurations.

If necessary, it is possible to equip our standard impulse test stands in such a way that it is possible to switch to a different pressure range without great effort.
