How does the hydraulic machinery manufacturer answer the 630 ton hydraulic press to improve the guiding accuracy?

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...

What are the effects of pressure disorders on a 630-ton hydraulic press? How to deal with it?

Pressure is a necessary condition for the normal operation of the 630-ton hydraulic press. If the pressure is insufficient, it will cause defective parts. The abnormal working pressure of the hydraulic system is manifested as: the pressure regulating valve fails when the hydraulic system is adjusted, the system pressure cannot be established, or there is no pressure at all...

Why does cavitation occur in the hydraulic cylinder of a 630-ton hydraulic press?

The four-column hydraulic press is an oil pump that delivers hydraulic oil to an integrated cartridge valve block. The hydraulic oil is distributed to the upper or lower chamber of the cylinder through each check valve and safety valve. A hydraulic press is a device that uses liquid to transmit pressure. when the liquid in closed capacity...

How does the 630 ton hydraulic press enter the air? What to do after entering?

The reason why the hydraulic press is easy to mix with air 1. The new hydraulic cylinder, the repaired hydraulic cylinder or the cylinder with too long downtime of the equipment, there is air in the cylinder or the exhaust in the hydraulic cylinder pipeline is not discharged; 2. Negative pressure is formed inside the cylinder. Inhale air from the outside; 3, from the cylinder...
