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.
