The Test Bench GDI High Pressure Pump has been designed for testing of gasoline high pressure pumps. Their characteristics are essentially defined by the integrated analog and digital volume control valve (VCV). The test bench measures the flow capacity and the operating pressure of the pump depending on the supply pressure, rotation speed, test fuel temperature, high-pressure and the adjusted VCV current or rather the time control of the digital VCV according to the bottom dead center.
The test bench has got two similar stations.
The stations have got separate and individual fluid circles.
This test bench is a semi-automatic machine with automatic test and manual loading and off-loading.
The test bench must be filled with Exxsol.
Highlights
- Automatic test process set up by flexible test plans. There is also the possibility to perform manual tests.
- Comfortable, individually adapted control software based on MS Windows 7.
- Sonplas touch screen control panel.
- Graphic display of measured values.
- Continuous record of the measurement values up to 100 Hz.
- All operating points of the high-pressure pumps can be freely adjusted and measured by the test bench.
- Power signal generating with Sonplas USD-output stage for digital VCV.
- True rms current regulation with Sonplas VCV-output stage for analog VCV.
- Water-cooled motors with accurate rotation speed regulation. Rotation speed measurement via incremental encoder (2048 increments).
- Test socket to measure all signals externally.
- Lube oil temperature regulation for CamBox.
