What are the three control methods of the hydraulic press

When we use the hydraulic press, there are no more control methods, of course, the control method here is not manual, automatic control method oh, but the control system of the hydraulic press, it mainly has three control methods, relay control, programmable controller and industrial control machine control, then we will introduce the three control methods of the hydraulic press.

1. Relay control mode

The relay control mode is relatively a more traditional control mode, the circuit is relatively simple, the technical requirements for the operator of the hydraulic press are not too high, the cost is relatively low, and its control function is relatively simple. The main thing is to work with a single machine, processing some products that are not very high in terms of product accuracy, such as kitchen supplies. However, the hydraulic opportunity of the relay control mode is limited by the circuit, and the stability is relatively poor, resulting in the relay control can only form a simple production line.

Second, programmable controller

Programmable control is developed on the basis of relay control, slowly developed into a microprocessor as the core, with automation technology, computer technology and other advanced technology integration into a new type of hydraulic press, now has been used by various industries, the development of programmable controller of hydraulic press is also rapidly developing, In the past, the programmable controller can only carry out some simple operation control in the function, but now with the development and development of technology, it has gradually developed into a microprocessor central processor, which strengthens the control function of the controller.

Third, industrial control machine control mode

The industrial control type of hydraulic press is a high-tech control mode developed after the computer control technology is relatively mature, which uses a single chip microcomputer or a single board machine as the main control unit, through the external interface device to achieve the control of the hydraulic system, but also the use of various sensors to achieve a closed loop to help the four-column hydraulic press to carry out accurate control.
