MORSØ Notch Cutting Machine
Model NXLEH
Description of the Hydraulic System
All automatic movements are carried out by means of the hydraulic system.
All the functions of the hydraulic system are adjusted from the factory. This must not be
changed as it can lead to disturbances in the process.
After starting the machine, wait about 1 second before the cutting is started. During this
period the oil pressure for the process is built up.
The hydraulic pump (2) driven by an electric motor (1) gives the hydraulic pressure
necessary to be used in the hydraulic cylinders (3), (4) + (5) for the conveying and the
movements of the knife block and clamping cylinders.
The hydraulic pump (2) draws the oil through a suction filter out of the tank (7) and to the
valves. After the pulse release the electronic control regulates the opening and the closing,
respectively, of the valves (8) so that the controlled cylinders are provided with oil.
Please note: If the hydraulic pump breaks, it cannot be repaired, but must be replaced
by a new pump.
The oil that is not used for the process goes back to the tank through the return filter (9).
WARNING
The built in hydraulic system must not be covered up and must be kept free of waste as
these things can cause extreme heating resulting in the worst damages.
