Fuel injection parts - Test Bench
1.Imported international advanced technology,use original packing imported converter,the test stand has wide speed scope and good dynamic performance. 2.Direct output of main motor,start up with low voltage,save energy,small value of reduction of speed,high measurement accuracy,good reliability,and complete automatic protection function.
3.Clockwise or anticlockwise rotation speed is 0-4000r/min.It adopts WZ-I full-function digital controller and displays seven shifts preset of speed, rotate speed, count, fuel oil temperature. And equipped with systems such as air supply positive and negative pressure,VE pump inner pressure, reture oil amount, direct current electric power source and so on. It has full functions
4.Controlled by industry computer and equipped with digital display. It can be used normally even if the computer is not start. It is really reliable and high cost performance.
5.The computer in the test bench has large-scale data base,more than 2000 technical parameters of fuel pump can be referred easily.

Main Technical Parameter of Fuel Injection Pump Test Bench
The test benaches are used for testing injection nozzle opening pressure, leakage Spray pattern, atomisation & chatter characteristic tests.
The test benches are suitable for wide range of fuel injection pumps including rotary and distributor types and covers every possible requirement for testing the full range of pumps. Very high precision indeed is demanded for the fuel delivery, port closing and speed control of modern diesel fuel injection systems-primarily so that optimum fuel consumption/power output ratios can be achieved.
