[0038] The motor independent simulation test principle and process: press the start button 3, and after obtaining the start instruction, the first starting valve 1 (electromagnetic valve) is powered on. High-pressure air enters the air motor 7 through the first starting valve 1 and the control air inlet pipe 13, and pushes the motor pinion outward. When the motor pinion extends to a certain length, the internal air passage of the air motor 7 is opened, high-pressure air enters the second starting valve 10 through the control air return pipe 14. The second starting valve 10 opens the main air pipe 11 under the action of high-pressure air, and high-pressure air enters the air motor 7 through the main air pipe 11, driving the air motor 7 to rotate at high speed.

[0039] Four sets of pressure sensors 12 are added to the starting system to record the control air inlet pipe pressure before and after the first starting valve 1 (electromagnetic valve), the control air return pipe pressure, and the main air pipe pressure, and the pressure is recorded and displayed through the recording display instrument 4.

A safety electromagnetic valve 6 is added to the control air return pipe 14, which is opened to release pressure when the air pressure is too high or too low, preventing damage to the motor caused by excessively high or low starting air pressure.

[0040] The motor independent simulation test content: (a) simulate the pressure detection after the electromagnetic valve is disconnected, and judge whether the motor pinion has the possibility of sudden extension by the control pipeline pressure.

[0041] (b) air pressure test simulating the extension length of the motor pinion, respectively detecting the minimum pressure required for the motor pinion to extend, start rotating, and rotate stably, and determining the pressure value required for the starting valve to normally open according to the minimum pressure at which the motor pinion rotates stably.

[0042] (c) air leakage test simulating internal failure of the electromagnetic valve, verifying whether the failure of the electromagnetic valve will cause the pressure in the control pipeline from the electromagnetic valve to the motor to increase, and judging whether the motor pinion has the possibility of sudden extension according to the leakage pressure.

The motor parameter monitoring system monitors and records the starting working parameters of the motor.

[0046] The motor and engine combined simulation test principle and process: press the start button 3, after obtaining the starting instruction, the first starting valve 1 (electromagnetic valve) is powered on. High-pressure air enters the air motor 7 through the first starting valve 1 and the control air inlet pipe 13, and pushes the motor pinion outward. When the motor pinion extends to a certain length and fully engages with the diesel engine flywheel 16, the air passage in the air motor 7 is opened, and high-pressure air enters the second starting valve 10 through the control air return pipe 14. The second starting valve 10 opens the main air pipe 11 under the action of high-pressure air, and high-pressure air enters the air motor 7 through the main air pipe 11, drives the air motor to rotate at high speed, and synchronously drives the diesel engine to operate. When the diesel engine speed reaches the ignition speed or the starting time exceeds the specified time, the first starting valve 1 is closed, and the motor pinion is disengaged from the flywheel ring under the action of spring force, and the starting is completed.

[0047] The motor and engine combined test mainly performs the starting performance test, and through the starting condition, the diesel engine ignition time, and the pressure change before and after starting, the running state of the motor can be further verified.
