Product Description
DB2000 Series Fuel Injection Pump Test Bench
Features of the test bench
DB2000 series fuel injection pump test stands, patented products created by Tsinghua University and our factory, are equipped with various kinds of sensors such as magnetic, hall effect, pressure, temperature, and use high-quality industrial computer, advanced inverter, color CRT as its parts. The test stand can be easily operated through the control panel. It is advanced in now world and its features appear clearly as followed.
1. Preset speed and measure times without error freely.
2. Auto-measure advanced angle of advanced device at any speed.
3. Auto-measure VE-pump oil-returning quantity and temperature.
4. High precision 0~0.5MPa & 0~-30KPa adjustable positive & negative air source.
5. Directive current supply 12V, 24V, 2A.
6. Reference for various pump tested.
7. Alarming for filter blocked and heating error.
8. Printer and internet web can be connected with the test stand (Please book it before produced)
