press machine hydraulic cylinder are widely used in Poland，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed press machine hydraulic cylinder for customers from Poland.

Introduction to press machine hydraulic cylinder:

When producing oil press machine hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

If the press machine hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

The piston rod and guide sleeve function of the press machine hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular press machine hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about press machine hydraulic cylinder:

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
