The function and characteristic of solenoid valve of four-column hydraulic press are introduced

What are the functional characteristics of the solenoid valve in the four-column hydraulic press we are using? Do you know that? Do not understand the small partner with Xiaobian to understand the function of the four-column hydraulic press solenoid valve. ,

First, with reversing reliability, after the electromagnet is energized, the first thing is to see in the state of electromagnetic force, can the solenoid valve safely ensure that it can be reversed at any time, if the electromagnet is disconnected from the power supply, the solenoid valve can be successfully reset in the case of spring force, want to effectively deal with the reliability of the solenoid valve reversing, It is necessary to pay attention to the quality of the product and the purity of the hydraulic oil in the manufacturing process, rationally plan the solenoid valve, and ensure that the valve body hole and the valve core (under the valve body) and other components have accurate processing, so as to improve the reversing reliability of the solenoid valve.

Two, with pressure loss. The pressure loss of the solenoid valve of the four-column hydraulic press is caused by the loss of activity and the loss of throttling, but because the opening of the solenoid valve is small, the loss of throttling is relatively large.

Three, with commutation and reset time. Under normal circumstances, after the solenoid of the large hydraulic press is powered on, the time to the spool (belonging to the valve body) reversing cutoff is 5 to 7 seconds, and the moment from the power failure to the spool returning to the original position is the moment when the solenoid valve is reset.

Four, with the electromagnetic reversing valve flow ability

The hydraulic power of the four-column hydraulic press will increase with the increase of the flow rate (unit: cubic meters per second), and the thrust of the electromagnet itself is limited, so the overflow of the magnet valve will be limited, and the difference between the valve core (under the valve body) machine is also related.
