Why is the running Dongguan generator suddenly stopped after continuous operation?
1 The lubricating oil pressure is low, and the bearing and the bearing bush cannot be fully lubricated. When the diesel engine is running at a high speed, the temperature of the Dongguan generator bearing bush will quickly rise, forming serious dry friction, and dissolving the bearing bush wear-resistant alloy.
2 The radial clearance between the bearing and the journal is too large, which reduces the contact arc between the journal and the bearing pad. This will increase the pressure load on the oil film, and will also increase the fatigue of the bearing pad. It will also increase the vibration and impact of the crankshaft, and the lubricant will be squeezed out Go out and lose the buoyancy of the oil film causing the tile to burn.
3Diesel engine is overloaded for a long time or is frequently started. The oil film of the generator in Dongguan is damaged, which will easily cause friction and wear, and eventually cause tile burning.
4 Improper assembly of the bearing pad. If the surface of the bearing pad and the bearing seat hole are sticky and poor during assembly, or if a sheet of paper is placed between the bearing pad hole and the bearing seat hole, the internal heat dissipation conditions of the bearing pad are not good.
