Automatic cutting machine abnormal high pressure processing.

Reducing hydraulic shock is an important step for hydraulic cutting machine manufacturers to deal with abnormal high pressure. Usually, the electro-hydraulic directional valve and the electromagnetic directional valve change direction at the same time, and then the opening of the flow valve slowly opens to make the motor move slowly. Because of inertia, the pressure in the cylinder rises, and the relief valve can prevent abnormal high pressure. Circuit to prevent abnormal high voltage caused by component failure of hydraulic cutting machine.

When cylinder 2 descends, if balance valve 1 fails to work and abnormally high pressure is generated on the piston rod side, relief valve 3 can prevent this situation.

Circuit to prevent abnormal high voltage when stopping. When the hydraulic motor 2 drives the load with large inertia and the directional valve 1 returns to the neutral position, a large hydraulic impact will be generated. The brake valve 3 can release the compressed high-pressure oil, and at the same time, the oil can be sucked out of the oil tank through the check valve to fill the vacuum in the oil pipe on the other side, so as to prevent cavitation.

High temperature of CNC cutting machine is a common mechanical failure, so it is very important to correctly understand and learn the maintenance knowledge of four column hydraulic machine. Pay attention to whether there is strange noise, smoke, abnormal temperature rise, etc. In the process of hydraulic cutting machine operation, timely detection and repair can prevent major failures and continuous damage to the press components.
