Impulse test stands up to 6,000 bar – Poppe + Potthoff systems

The Poppe + Potthoff impulse test stands test the operating or fatigue strength of various metal and plastic components. The endurance test in our high-pressure test systems simulates the life-cycle under varying loads. The failure tests thus show the potential weaknesses of the components with respect to design and material. The pressure is optionally modulated as a sine wave, trapezoid curve or needle pulse. Our test stands are characterized by a special ergonomics and are designed by Poppe + Potthoff machine design. Due to our flexible modular design, our machines are very variable, so that the pressure and volume range is designed according to the customer’s requirements. Of course, our systems are UL or CE compliant as required. In addition, we offer you service and support directly on-site.

Varying pressure
The pressure can be controlled very precisely by means of servo hydraulic pressure boosters that are optimally designed for the test area desired by the customer. It can vary depending on the frequency and impulse volume, or it can remain constant for long-term tests or can be increased to bursting point.

Applications

  • Impulses from 0 to 6,000 bar at a frequency of up to 30 Hz
  • Testing the operating and fatigue strength of high-pressure components
  • Stress tests in research and development, as well as on a series-basis
  • Sine and trapezoidal test curves
  • Needle pulses in 5ms

Services
In general, we also offer pulse testing in the relevant pressure and frequency ranges as a service. Whether for research and development or for once-in-a-lifetime tests, please contact us with your test requirements for a non-binding offer.

The impulse pressure is generated by a pressure booster with a hydraulic drive. A hydraulic power unit generates a constant hydraulic pressure of 350 bar. This pressure drives the pressure booster via a regulator valve. The pressure booster has a constant pressure boosting ratio and produces the high pressure due to its linear movements. A highly dynamic servo regulator valve is used as the regulator valve, which allows very high test frequencies with precise repeatability. The test pressure profile is measured and stored with a pressure transducer. These records allow the quality of the test to be assessed later. The pressure-control system of the plant also operates via this pressure sensor. The test medium is hydraulic oil. A perfectly tuned cooling system keeps the temperature at the pressure booster and in the hydraulics in equilibrium. Cooling is a very efficient water cooling system. Visualization of the test sequence is carried out via a PC. The operation is menu-driven and enables special software configurations. The system is self-monitoring. Possible faults are displayed on the monitor and lead to the system being switched off. Test failure is detected via an oil mist sensor. If an automatic shutdown occurs, an info message about telecommunication is sent to a mobile phone. All data relevant to the test is preserved, of course, and is automatically saved.

Performance data:

  • Pressure booster for additional supply
  • Temperature-controlled head-cooling
  • Easy access to pressure booster
  • can be converted to various pressure ranges (600 bar, 1,500 bar, 3,000 bar, 4,500 bar, 6,000 bar)
  • Digital communication within the system
  • Camera-monitoring of the test object and the cables
  • LabVIEW application is self-extensible
  • Separate controller parameters for each part of the load group
  • Separate recording of statistical data of the upper and lower actual values

Application areas:

  • Research and Development
  • Accompanying endurance test of serial parts
  • Automotive suppliers
  • Optimization of assemblies

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.
