During the operation of the hydraulic press, maintaining the normal temperature in the oil tank is the premise of the normal operation of the hydraulic press. Hydraulic machine temperature rise is too high will cause a series of hazards such as mechanical thermal deformation, rubber seal deformation, accelerated aging failure, reduce sealing performance and make...

In many systems, we maintain strict requirements for the pressure of the 630-ton hydraulic cylinder. If the pressure does not meet the standard, it will inevitably affect the actual work effect, so we must deal with the problem of pressure failure as soon as possible. Today, Shandong Tengzhou public...

There are several problems of pressure loss: 1. Pressure loss along the way. The pressure loss caused by viscous friction when the oil flows in the straight pipe of equal diameter becomes the pressure loss along the way. 2, local pressure loss hydraulic oil flow through the pipe elbow, joints, mutation...

At present, the sliding block of hydraulic press is guided by 45 inclined guide rail fixed on the fuselage pillar. In order to improve the wear resistance and facilitate the maintenance, bronze plate is usually inlaid on the sliding block guide rail surface. The fuselage rail is made of wear-resistant cast iron or hardened steel. in precision punch...
