Overheating fault is called overheating when the temperature exceeds the specified value at the friction between the crankshaft and the bearing, the crosshead and the sliding plate, the packing and the piston rod, etc. The consequences of overheating: one is to accelerate the wear between the friction pairs, and the other is the continuous accumulation of excessive heat, which directly burns the friction surface and causes major accidents of the machine. The main reasons for the overheating of the bearing are: uneven adhesion between the bearing and the journal or the contact area is too small; the bearing is skewed and the crankshaft is bent, the lubricating oil viscosity is too small, the oil circuit is blocked, the oil pump is faulty and the oil is cut off, etc.; there is no leveling during installation, The gap is not found, the main shaft and the motor shaft are not aligned, and the two shafts are inclined.
