What causes mechanical failure of the crankshaft of the generator set?

Some users reported that when pressingGenerator setAfter the switch is turned on, the unit itself reacts but the crankshaft cannot rotate, causing the entire unit to fail to start. Haixing reminds everyone that at this time, you need to consider whether it is caused by a mechanical failure of the crankshaft.

There are many reasons for crankshaft failure, and there are three main reasons. You can compare them to find out the root cause.

1. There is poor meshing between the unit and the flywheel teeth. The ring gear and starter gear will collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth in a row are damaged or severely worn, it will be difficult for the starter gear and ring gear teeth to mesh.

2. Sticky cylinder. When the engine temperature is too high, the engine stalls and the heat is difficult to dissipate. The piston rings at high temperatures adhere to the cylinder and cannot be started after cooling.

3. The crankshaft is locked. Due to a failure in the lubrication system or a lack of engine oil, the sliding bearing causes dry friction, causing the crankshaft to lock and unable to start.

If the unit cannot start after you press the start switch, do not press the switch fiercely. If you find a crankshaft mechanical failure, you need to investigate the causes one by one and find out the problem and solve it as soon as possible to avoid affecting the entire work process.
