Maximum Pressure Valve
As a safety measure to guarantee the operator's safety and to safeguard the machine, a maximum pressure valve is installed inside the hydraulic control unit on all hydraulic presses produced by LIVAMACH.
The maximum pressure valve has the function of regulating the maximum pressure in the hydraulic circuit.
It is used to protect the pump and the other components of the system from excessive pressure and therefore to keep the level inside the hydraulic circuit constant.
It is a normally closed valve capable of opening when a predetermined pressure is reached and discharging the flow rate necessary to keep the circuit pressurized.
In fact, in the event of a malfunction of the hydraulic circuit, this safety valve prevents an excessive quantity of oil from reaching the cylinder, thus preventing the risk of overpressure.
Lever Protection
As a safety measure, the operating lever is protected by a metal guard.
This measure is used to ensure that the lever can only be moved with the use of the fingertips and that it cannot therefore be operated through an involuntary impact or a fall of the operator.
Furthermore, as a further form of safety, the operation of LIVAMACH presses requires that the lever, when pushed forward, raises the cylinder, while if it is pushed towards the operator, the cylinder descends.
This means that even in the event of the operator accidentally falling and involuntarily hitting the lever, the latter would be pushed forward and raise the cylinder and not the other way around.
In fact it is clear that only the descent of the cylinder is dangerous, while its ascent never involves risks for the user.
Anchoring Electrical Cables
The tubes for the passage of the electrical cables are anchored to the press frame by means of special collars.
Unlike many competitors who use simple plastic ties that are destined to dry out and break quickly, these collars are made of highly resistant material and are screwed to the structure of the press.
Anchoring Hydraulic Pipes
As a safety measure the hydraulic hoses of all the presses produced by LIVAMACH are firmly fixed to the machine frame using special collars which prevent any movement of the hydraulic hose.
These collars have the base welded to the frame, while the upper part is screwed.
Stopflex Anchor
All the presses produced by LIVAMACH include safety systems for anchoring the hydraulic pipes.
In fact, the force released by a flexible hose under pressure, in the event of the fitting slipping out, would be very dangerous for things or people nearby.
It is for this reason that the hydraulic tubes of all the presses produced by LIVAMACH are fixed using the Stopflex retention system, which was designed to stop the stroke of the pulled tube and prevent the force released inside it from triggering a fearful " whip effect” and at the same time flood the working environment with hydraulic oil.
Thanks to this system, in fact, the flexible hose is anchored to the system via a rope, thus guaranteeing full protection of the operators and the protection of the press and the workshop.
Current Transformer
The press works with a three-phase electrical system with a 400V power supply.
As a safety measure there is a transformer inside the electrical panel which reduces the current from 400V up to 24V, that is, up to a voltage that is not dangerous for human health.
In fact, in the event of a system malfunction, the current could propagate to the electrical panel, with the risk that the operator could suffer an electric shock when he presses one of the buttons on it.
