Werkstattpresse mit elektrischer Pumpe “WP60EEC”
SAFETY PREVENTIVE ACTIONS AGAINST OTHER RISKS
™ Risk due to power supply: The machine is equipped with the fuse and a thermo-magnetic switch for its protection.
™ Risk due to hydraulic power: The hydraulic pump is equipped with an internal security valve in the tank, out of operator's control and rated at 70
MPa , as well as with a pressure relief valve on the tank cover adjustable by the operator from 0 to 70 MPa. The hydraulic cylinder is also
furnisher with a pressure relief valve, rated at 70 MPa, which prevents the retraction chamber of the cylinder from overpressures in case of
obstruction of the return way.
™ All the maintenance operations must be performed while the machine is stopped, thus avoiding this way any potentially dangerous situation.
™ A poor maintenance program of the press does not increase the risk, but obviously will revert in a lower performance.
™ The hydraulic pump is mounted in the frame and access is very easy. To disassemble the pump, unscrew the bolts in the tap cover. In order to
disassemble the cylinder it is required to first disassemble the piping.
™ Isolation of the power supply: Release the terminal wiring to disconnect the power supply. Previously you should unplug the pin.
™ Handling by the operator: The machine is designed to assure that all maintenance tasks are performed by the operator in an easy and safe way.
All the components that would require any maintenance operation are easy accessible.
™ In the valve, you can find several marks depending on the position of the lever:
•
"A" for extension of the cylinder piston.
•
"B" for holding the pressure without piston movement.
•
"C" fir retraction of the cylinder piston.
The press, the cylinder and the electric pump have their corresponding serial numbers marked on them. In addition to it, you can find a sticker label
showing the commercial reference, capacity, working pressure, name and address of the manufacturer.
4. TRANSPORT UND AUFBAU
The machine is delivered properly packed in a wooden ballet. For it’s handling, it is recommended to use a forklift truck or a crane. In the last case, it is
necessary to make the slings trespass the arc of the frame. When doing this operation, you should be cautious and prevent the flexible hoses and
couplings from any damage.
The machine is stable enough to operate without fixing, but if is placed in an area commonly operated by mobile machinery (cranes, lifting
equipment…) it is strongly recommended to fix it to the desired place by drilling the supporting plates.
Bear in mind the voltage indicated in the terminal box of the motor. Assure that the directional distributor valve’s command is in position “C”.
Check that the motor rotates in the sense of the arrow labelled in the electrical motor. In opposite case, change the position of two cables between
themselves in the terminal and try again. This operation will be made with the equipment depressurized.
SUBSTITUTION OF THE TRANSPORT PLUG
Replace the plug of transport located in the cover of the tank, by the pressurized plug given with the press. (Plastic bag on the lever of the valve).
INSTALLING THE GAUGE
1-Replace the threaded tap at the top of the cylinder by the gauge. (Supplied separately).
2-Tighten the gauge cone to the gauge adaptor seat by using a flan wrench size 22.
3-Hold the gauge screen by hand during threading process and after reaching a comfortable reading position set the gauge screen free so that it turns
the last quarter solidary with the thread.
4- The hydraulic system also includes a gauge adaptor with 3/8 “BSP thread.
CHECKING THE RIGHT OPERATION OF ALL DEVICES AND MECHANISM
1. Switch the black ON/OFF Switch on the electric box to position “1”.
2. Switch the distributor valve’s command to position “C”, push the green push button of the remote control and do not stop pushing it.
3. Check the rotate of the motor.
4. If the rotate sense is the opposite of the labelled arrow in the motor, change the phases of the electrical connection. Disconnect the
equipment for this operation.
5. Switch the distributor valves command to “A” position. The cylinder’s piston advances, familiarize with the speed.
6. Guide the piston to the end of the stroke and submit to pressure, check the reading of the gauge and that there is not oil leaks.
7. Switch the distributor valves command to “C” position to assure that the cylinder maintains the pressure.
8. Switch the distributor valves command to “B” position to return the piston, familiarize with the speed.
9. Stop pushing the green button on the remote control, to stop the motor. Move the command from “A” position to “B” position to depressurize
the cylinder and finally let the distributor valve’s command in “C” position.
10. Switch the black ON/OFF Switch on the electric box to position “0”.
