What Should I Do If 100 Tons of Hydraulic Press Are Suddenly Lost?

Reduce the Storage Capacity of Liquid Elastic Energy. The Elastic Energy of Liquid Storage Is Proportional to the Height of Liquid in the Working Cylinder. Therefore, the Backing Plate Can Be Thickened between the Four-Column Hydraulic Press Workbench and the Lower Mold to Move the Working Stroke of the Movable Beam up, to Reduce the Height of the Liquid Column of the Working Cylinder. There Is Also a Movable Pad between the Piston of the Working Cylinder and the Movable Beam, That Is, When the Four Columns Are Hydraulic Press Idle Stroke Downward, the Piston and the Beam Fall Together. after Contacting the Workpiece, before Pressurizing, the Piston Returns and Rises First. at This Time, It Assists the Hydraulic Cylinder to Move the Movable Pad into the Piston and the Movable Beam. Reducing the Pressure of the Working Medium Can Also Reduce the Energy Stored by the Liquid.

Other Ways to Release Energy. That Is to Say, at the Moment When the 100-Ton Four-Column Hydraulic Press Is Suddenly out of Load, Part of the High-Pressure Liquid in the Working Cylinder Is Quickly Leaked to Reduce the Energy to Be Released. This Method Is More Effective When the Liquid Pressure Is High, but Requires the Sensitivity of the Corresponding Electro-Hydraulic Control Valve to Be Relatively High, and at the Same Time, It Should Not Cause Large Vibration of the Side Drain Pipe.

Absorb Energy to Shock Absorption. Set Hydraulic Press in the Lower Part of 100 Tons of Crash Pad, Adjust to the Material Is about to Cut off, at the Moment of Cutting off, the Movement Part of the Contact Crash Pad, So as to Consume Part of the Energy on the Compression Crash Pad. Crash Pad Can Be Hydraulic Buffer Or Gas-Liquid Buffer.
