On the premise of ensuring good air and electricity, press the start button to start the solenoid valve and open the control air. Under the action of the control air, the drive shaft meshes with the diesel engine flywheel, and then the control air further opens the axial start valve, allowing the starting air to enter the starting motor and drive the turbine to rotate at high speed. The high-speed rotating turbine drives the drive shaft to rotate together through the differential gearbox, thereby driving the diesel engine to rotate to the specified speed. At this time, the starting solenoid valve automatically loses power, cuts off the control air, and resets the drive shaft and stops the starting motor.
