1. Proximity switch: The proximity switch not only controls the stroke of the 500-ton auto parts hydraulic press, but also plays a protective role. The proximity switch has almost no problem even if we use it normally.
2. Relays: There are many small relays in the electrical equipment box of the 500-ton auto parts hydraulic press, and all the action relays of the 500-ton auto parts hydraulic press work.
3. The electromagnetic coil of the electromagnetic cartridge valve: The electromagnetic coil of the electromagnetic cartridge valve is used for the action of the 500-ton auto parts hydraulic press. The damage or failure of the magnetic ring is generally caused by voltage instability.
4. Button insensitive: New equipment with insensitive buttons usually does not appear, because the 500-ton auto parts hydraulic press will be debugged in the factory, and button insensitivity will generally appear on old equipment.
5. The pressure holding time is useless: the pressure holding time of the 500-ton auto parts hydraulic press can be adjusted, but if the pressure holding time of the 500-ton auto parts hydraulic press does not reach the time we set or does not maintain the pressure, it depends on whether the time relay of the electric box is still working.
