Main function of 12PSDW diesel pump test bench:
1.Measurement of each cylinder delivery at any speed.
2. Test point and interval angle of oil supply of injection pump.
3. Checking and adjust the mechanical governor.
4. Checking and adjusting the distributor pump.
5. .Experiment and adjusting of behavior of supercharging and compensatory device.
6. Measurement of oil return of distributing pump
7. Testing of the electromagnetic valve of distributor pump.(12V/24V)
8. Measurement of the internal pressure of distributor pump.
9. Checking of the advance angle of advance device.(on request)
10. Checking the sealing of injection pump body
11. Install tube of auto-sucking oil supply can check on oil supply pump(including VE pump.)
