Knowledge of piston rod forgings
Many people for the piston rod this part or relatively understand, but we did not carefully understand the relevant knowledge of the piston rod, so the next main related knowledge is, the processing technology of the piston rod, the use of the piston rod product and the related causes of the piston rod overheating.

Processing technology of piston rod:

The piston rod forgings are processed by rolling, so as to improve the corrosion resistance of the surface and delay the generation or expansion of fatigue cracks, so as to improve the fatigue strength of the cylinder rod. Through ROLLING FORMING, a cold hardening layer IS formed ON the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, so as to improve the wear resistance of the cylinder rod surface and avoid the burn caused by grinding. After rolling, the surface roughness decreases and the mating properties are improved. At the same time, the friction damage to the seal ring or seal during piston movement of the cylinder rod is reduced, and the overall service life of the cylinder is improved. Rolling technology is a kind of high efficiency and high quality technology measure.

Product use of piston rod:

Piston rod FORgings are mainly used in hydraulic pneumatic, construction machinery, automotive manufacturing piston rod, plastic machinery guide column, packaging machinery, printing machinery roller, textile machinery, transmission machinery axis, linear motion with the straight axis.

Causes of overheating of piston rod forgings:

when the piston rod and stuffing box assembly is skewed, causing local friction, should be adjusted in time;

the sealing ring holding spring is too tight, the friction force is large, should be adjusted appropriately;

 If the axial clearance of the sealing ring is too small, the axial clearance should be adjusted according to the requirements;

The amount of oil is insufficient, and the amount of oil should be increased appropriately;

the piston rod and sealing ring run-in is not good, should strengthen the run-in when matching research;

 Gas and oil mixed with impurities, should be cleaned and kept clean.

The above is the relevant knowledge of the piston rod, I hope you can understand the piston rod more, but also hope that this article can help you.
