Pressure impulse test stand PPM

pressurefatiguedurability

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
