Pressure, impulse, pressure fatigue

Similar to the high-pressure range of up to 6,000 bar, the hydraulic pressure used to run conventional impulse test stands is 330 bar. The energy generated by the hydraulic power unit powers the pressure booster via a regulator valve. The pressure booster’s linear movements provide a high pressure while maintaining a constant ratio. We also use high-dynamic servo-regulator valves in our standard systems to provide exact repeatability even at high test frequencies. The system’s pressure is regulated using a pressure transducer.

Hydraulic oil is used as the test medium. A carefully calibrated cooling system keeps the temperature at the pressure booster and in the hydraulics in balance. The cooling is accomplished by a very effective water-cooling system.

To assess the quality of the tests, the test pressure profile is measured using the previously specified pressure transducer and stored in the system as a data record.

The test sequence is visualized and evaluated using a PC. The operation is menu-driven and supports custom software setups. If necessary, we may adapt our conventional impulse test stands so that they can easily transition to a new pressure range.
