Functional characteristics of four-column hydraulic press solenoid valve

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 economy, but because the opening of the solenoid valve is small, the loss of economy is relatively large.

Commutation and reset times

Under normal circumstances, after the electromagnet of the regular four-column hydraulic press is powered on, the time until the spool reversal is cut off is 5 to 7 seconds, and the time from the power off to the spool returning to the initial position is the time for the solenoid valve to reset.

Maximum overcurrent of solenoid directional valve

The hydraulic power of the four-column hydraulic press will increase with the increase of the flow rate, and the thrust of the electromagnet itself is limited, so the maximum overcurrent capability of the solenoid valve will be limited, which is also related to the difference with the spool machine.

Commutation reliability

After the electromagnet is energized, the first thing for a four-column hydraulic press is to see if the solenoid valve can be reversed in the presence of electromagnetic force. Reset, if you want to effectively handle the reliability of the solenoid valve reversing, you need to pay attention to the quality of the product and the purity of the hydraulic oil during the manufacturing process, and plan the solenoid valve reasonably to ensure the valve body hole and valve of the solenoid valve of the four-column hydraulic press. Components such as cores are processed with precision to improve the commutation reliability of the solenoid valve.
