How to deal with the loss of load of hydraulic press

by:WORLD     2022-10-01
What should we do when the hydraulic press loses load? Today, the Shanghai WORLD Press Machine of WORLD Press Machine will discuss this issue with you. Readers who have different solutions can leave a message below.

On the one hand, it can be considered that the hydraulic press adds the storage capacity of the liquid bomb function. 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, so that the working stroke of the beam is moved up, and then the height of the oil in the cylinder is lowered.

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 effect of the spacer, which has the effect of adding 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 will not be released suddenly, and the problem of loss of load can be alleviated.

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

A buffer pad is added under the hydraulic press, which can buffer the machine and reduce the vibration of the machine, and some energy will be consumed on the buffer pad, which can effectively reduce the damage to the machine.
