EUI/EUP Tester Cambox with computer
Ⅰ. Main Functions and Scope of Application
The unit pump control box is suitable for testing electronically controlled unit pumps and pump nozzles.
The main function:
1. Speed display
2. Editing of driving parameters
3. Single or double valve test
4. BIP display settings
5. Fuel injection delay display (optional)
6. Driving feature editing
Ⅱ. Test Preparation
1. Unit pump Clamping and Fixing
The unit pump cam box is clamped on the test bench for testing, fixed on the guide rail, and the injector to be inspected is clamped.
2. Control Box Wiring
The rear panel of the unit pump control box is shown in Figure 2.1.
Please connect the patch cord on the rear panel of the control box as shown in the figure. Connect the power socket to the AC 220V power supply and turn on the power switch.
3. Test Bench Wiring
After the line at the rear of the control box is connected, the line of the main motor driving control box is connected. Finally, the main power line is connected according to the corresponding power distribution of the test rig. Make sure there is no error, the test can be started.
Ⅲ. EUP/EUI Test Preparation
1. Test Bench Power Supply
Open the main switch on the test bench side and prepare the main motor.
2. EUI/EUP Test instructions：
A. Check the ohmic value of the injector solenoid valve.
B. Move the main drive disc by hand to ensure that the camshaft rotates 360° without jamming.
Adjust the injector to run the maximum stroke on the cam box and keep the same ejector height for the same set of injectors.
C. Test the oil pump motor start button, the oil pump starts the oil supply, and the same group fuel injector uses the same oil supply pressure.
D. Call out the control box test data and keep the same test plan for the same group of injectors.
E. Start the main motor to test the oil quantity and find out the products with inconsistent oil output for maintenance.
3. Main motor operation
Set the appropriate speed on the main motor drive control box and run the main motor
