Component description:
•
Return flow system:
(Fig.4.2.1)
Description -
The return system is a kind of safety device. The operating principle of this system is regulated by the pressure
control valve. If the set pressure is reached and / or exceeded, the excess injection material is transported back into the
material container via a connecting line.
Advantages:
•
Overload protection for the drive
•
Injection material remains in motion (recirculation)
•
Pressure measuring uni
- this is used for pressure control.
(Fig.4.2.2)
Description
- The special feature of this valve is its design. This was selected so that the
respective injection material has no direct contact with the pressure gauge. In the pressure
measuring unit there are two areas separated by a diaphragm. The resulting operating pressure
(shown in red)
presses the diaphragm upwards; the oil filling above the diaphragm
(shown in green)
is thus compressed and the resulting pressure is transmitted directly to the pressure gauge and
displayed accurately.
Advantages:
•
Pressure fluctuations and pressure deflections are strongly minimised
•
Long service life of the pressure gauge
Fig.4.2.2
•
Pressure regulating valve
- this serves for pressure setting
(Fig.4.2.3)
Fig.4.2.3 (Pressure regulating valve)
Description
–
On reaching the operating pressure, the pressure control
valve opens and the excess pressure is fed back into the material container
via the return flow.
ATTENTION:
The pressure control valve is a safety component. The
adjustable pressure is fixed at the factory; subsequent
adjustment by the operator is prohibited.
4.3 Technical specification
Design -230V-
The sound pressure level of this machine at a
distance of 1m is between
78 dB and 89 dB
(A)
and thus under
80 dB
(A).
Appropriate soundproofing agents should still be
used.
The sound pressure level was determined
according to EN ISO 11200 (using basic
standard 11203
The sound pressure level at the respective place of
operation can significantly exceed the sound pressure level
of the machine.!!!
