What are the causes of the oil cylinder strain of the stretching hydraulic press?

Causes of short-term strain on oil cylinder of tensile hydraulic press:

First, severe overload;

Second, the slider hole is seriously not perpendicular to the surface;

Third, there are more than 2mm hard sharp angle particles in the oil cylinder;

Causes of long-term strain on oil cylinder of tensile hydraulic press:

First, the abrasion of the guide sleeve of the column causes the oil cylinder to be protected without sliding block,

Second, the slider face is weak and not vertical;

Third, the accumulation of tiny particles on the upper part of the piston;

Several major factors causing the oil cylinder strain of hydraulic press are:

First, the slider hole surface is not vertical;

Second, the pipeline has rust and iron slag;

Third, cylinder deformation;

Fourth, partial load (the slide hole surface is not vertical equivalent to the partial load state);

Fifth, the oil cylinder cannot be cleaned up;

Sixth, the filter filtering accuracy is not enough.
