Causes of compressor overheating

Causes of compressor overheating

(Summary description)Overheating fault In the friction between the crankshaft and the bearing, the crosshead and the sliding plate, the packing and the piston rod, the temperature exceeds the specified value, which is called overheating. Consequences of overheating: one is to speed up the wear between the friction pairs, and the other is that the overheating heat continues to accumulate until the friction surface is burned, causing a major accident of the machine. The main reasons for bearing overheating are: uneven fit between the bearing and the journal or too small contact area; the bearing is skewed, the crankshaft is bent, the viscosity of the lubricating oil 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 spindle and the motor shaft are not aligned, the two axes are inclined, etc.
