Technical Parameters

Main Characters and Functions

1. Adopting the industry computer. The High-speed acquisition and control board, and the 17 inch or 19 inch LCD.

2. Adopting the imported famous transduter,which has the accurate controlment and low noise.

3. The sensor collects the oil distribution and the oil return and all the data is displayed in the screen.

4. The system can automatically testing and judging errors according to the presetting programmes.

5. Can be connected to the net and up data the data base with the function of soft upgrading and expansion.

6. The CR pump load and rail pressure are adjusted by setting the duty cycle of the pump driving signal.

7. Rail pressure IS monitored on the LCD screen.

8. Checking of the Common Rail pump’s pressure regulator valve performance.

9. Checking of the rail pressure sensor performance.

10. Checking of the safety pressure regulator valve performance.

11. Checking the oil distribution of the Common Rail Injector.

12. Checking the oil return of the Common Rail Injector.

13. Checking the uniformity of the Common Rail Injector.

14. Short circuit protection for the output circuitry of solenoid driving signal.

15. Has the over load protection function,when the rail pressure reached 1600bar, it will stop automatically.

16. Checking the output oil efficiency of the common rail pump.
