By employing high performance/low noise inverter and using Bosch advanced techniques Our testbench has had more and more advantages, such as, wide range of adjustment speed, stable speed, large torque outputting, frequency control, digital display and automatic temperature control technology easy operating and so on. This test bench used digital indicators to display speed, counting, test oil temperature, pressure/vacuum and advance angles.
The test bench of 12PSB series in it’s 12 cylinders with 5.5/7.5/11/15/18.5/22kw motor, can start and test both in-line and rotary fuel injection pumps, for example, Ⅰ, Ⅱ, Ⅲ, A, B, P, Z, VE pumps and so on, by employing the suitable accessories.
