Why is the flywheel when the diesel generator set is turned on?

Diesel generator setsSometimes, when it is turned on, it can hear the motion sound of the electromagnetic switch and the high speed rotation of the drive gear, but the flywheel of the diesel engine does not rotate. This is usually caused because the drive gear and the flywheel ring gear do not mesh or the starter drive gear slip is caused. The following starlight is to analyze the causes and solutions of this phenomenon.
1. If the flywheel does not move, the second or even the third boot start. If it is not excluded, the pitched screwdriver is applied to adjust the adjustment screw on the lower end of the upper end of the start of the starter, so that the drive gear and the flywheel ring gear mesh. If the failure is still not excluded according to the above adjustment, the parts such as drive gears in the starter should be disassembled for inspection.
2. If inspected, the driving gear of the starter generator is intact, and the startup cannot be engaged together at startup, the starter still occurs, and there is a metal collision sound, and the starter should be decomposed. If the distance between the cutting blocks is too large after the decomposition, the drive mechanism cannot be dial in place, the application is pressed to reduce the distance between the two bumps. When the bumps are worn by the bumps or the bumps while the bumps are damaged, the method can be treated with a method of welding.
3. If the coding distance is appropriate, the drive gear can also mesh with the flywheel ring gear, but when the starter still has a high-speed rotation, apply one hand to the armature to rotate the drive gear. If the clockwise can rotate and counterclockwise cannot rotate. It will illustrate that the motor mechanism works well; if it is rotatable when the clockwise and counterclockwise can be rotated, the drive mechanism is damaged and the new piece should be replaced.
