How to deal with sudden load loss of hydraulic press

The sudden loss of load of the hydraulic press is similar to the loss of load of other equipment. Since the oil with huge energy has been stored in the hydraulic cylinder, it will cause a loss of load once it is suddenly released. This is a very serious fault for hydraulic presses. How does the manufacturer deal with this?

On the one hand, it can increase the storage capacity of liquid elastic energy for the hydraulic press. Generally speaking, the height of the oil in the hydraulic cylinder is inversely proportional to the elastic potential energy stored in it. A backing plate is added between the gaps of the mold to make the working stroke of the beam move up, thereby reducing the height of the oil in the cylinder.

Or add a movable pad in the gap between the hydraulic cylinder piston and the beam, when the machine moves downward, the piston and the beam can fall synchronously. However, after pressurization, the piston will rise first due to the action of the pad, which increases the storage capacity of the elastic potential energy of the liquid. It is precisely because the height of the hydraulic oil is lowered that the energy is not released suddenly, and the problem of loss of load can be alleviated.

In order to solve the problem of the sudden loss of load of the hydraulic press, the energy can also be released from the other doors, so that the high and low pressure liquid in the hydraulic cylinder can be quickly discharged from the side. Although this treatment method is effective, it requires the operator to be more sensitive to the machine to avoid damage to the machine.

In addition, if a buffer pad can be added under the hydraulic press, it is also very beneficial for the machine. Because it can buffer the machine and reduce the vibration of the machine when the machine suddenly loses load and discharges the energy, and part of the energy is also consumed on the buffer pad, which effectively reduces the damage to the machine.

If you master these three methods, it is enough to deal with the sudden loss of load of the hydraulic press, and fully protect the machine, which is helpful for the normal progress of the follow-up work.
