Analysis and Resolution of Common Faults in Compressors 3
Thread Content
Reasons for broken rod-piston rod connection: ① The rod bolt is tightened too much. ②The split pin has broken off, the nut is loose, and there is excessive wear on the thrust washer. ③The bolt is over-fatigued. ④The clearance is too small, causing the piston rod to bend. ⑤The piston is stuck. Treatment: Carry out treatment after parking for maintenance.
1: Lack of lubricant, 2: Quality issue with spare parts
The pressure is extremely high, and there is a foreign object inside the cylinder.
There are dead points inside the cylinder, the clearance between the upper and lower bearings is incorrect, and the material of the connecting rod is of poor quality
The operating cycle is too long, the piston rod and connecting rods become overly fatigued, the pressure is too high, and the packing burns, resulting in damage to the piston rod.
Assembly quality, component quality, main pressures under operating conditions, as well as oil supply and oil quality in the lubrication system
