How to avoid non-return for four-column hydraulic press

- Jun 17, 2020-

Four-column hydraulic press, which is a common and commonly used type of hydraulic press, and for all of us, it is also important to familiarize and understand, because it is a website product and keyword, so based on this, the next step is to carry out this type of hydraulic press Explain the relevant knowledge so that everyone has learning objects and learning content.

1. What are the up and down speeds of the four-column hydraulic press? How to ensure that the problem of non-return does not occur?

The up and down speed of the four-column hydraulic machine is mainly related to the flow rate of the pump. If the pump cannot meet the flow rate, then the pump that can meet the flow rate needs to be replaced to ensure that the hydraulic machine can work normally. And to ensure that there is no problem of non-return on the hydraulic machine, one is to ensure that the cylinder has good sealing performance and sealing effect, and the other is to ensure that the solenoid valve can work normally, so as to achieve the goal.

2. What are the instructions in the four-column hydraulic press?

Four-column hydraulic press, this is a specific model of the four-column hydraulic press. In the instruction manual, it is necessary to include the general outline of the product and the use and characteristics of the product. These contents are indispensable. The specific use of this kind of hydraulic press is to press plastic materials and plastic products. In the pressing process, there can be stamping, bending, flanging, and stretching.

3. Pressure and down speed in a four-column hydraulic press

Generally speaking, the slider will enter a normal state when it drops through its own weight, so its downward speed is related to the pressure of the master cylinder. When the upper mold and the lower mold are in contact, it has a great influence on the downward speed, but when the mold has a bottom dead center, the slider will stop. If it is an overflow of the overflow valve, the phenomenon of deceleration will occur. In addition, some four-column hydraulic presses use switched reluctance servo motors to start the hydraulic pumps to achieve intelligent control, making the hydraulic press easy to operate and reliable to use.

4. Is the hydraulic cylinder in the four-column hydraulic press important? What constitutes it?

The hydraulic cylinder in the four-column hydraulic press is a key and important component, and it is an indispensable component. It is composed of cylinder barrels, cylinder heads, pistons, piston rods, and other components. In the device, it is There are sealing devices, buffer devices, and exhaust devices.
