The product is a pulse generator test bench,which is mainly used to detect the parameters of the pump, main valve and control valve. After the pump is tested and adjusted to a certain pressure, the pump displacement is up to > 1.45l/min; the control valve is tested to reach the voltage of 9V, the valve is opened to pass the oil, and the voltage of 14V, the valve is closed to block the oil flow; under the set conditions, the time for the main valve to pass the oil to 50ml is between 6-10s, and the time for 1L is between 14-21s.
