Fitters and setters of machine tools. They
have to be familiar with the handling of
hydraulic components.
The hydraulic intensifer has been
designed for the use in clamping fixtures
to increase the hydraulic pressure.
Pressure intensification is effected in
intensification ratio i.
!Swarf or contamination in the hydraulic
oil lead to damage of the intensifier.
!Insert filter 10µ for continuous
functioning.
!Use hydraulic oil as per data sheet
A0.100.
!If the intensifier will be used on
uncoupled systems (no connection to
the pressure generator), a pilot-
controlled check valve should be
mounted at the high-pressure side to
guarantee a safe holding of the load
(data sheet C 2.9511).
The hydraulic intensifer increases the
pressure at the input side to a higher
pressure in the indicated intensification
ratio i (see chart page 2).
The intensifer allows a high flow rate at
low pressure and switches automatically
to pressure intensification in case of
increasing counter pressure.
!Hydraulic connection.
!For pressure built-up line Rto the
reservoir has to be discharged.
!Pressurise port IN (pressure will be built
up in line H).
!Pressure intensification will be
automatically activated.
!To retract the cylinder line Rhas to be
pressurised and line IN to the reservoir
discharged.
!Connect hydraulic lines to qualifying
standards, pay attention to scrupulous
cleanness! See also Roemheld data
sheets A0.100, F9.300, F9.310 and
F9.360.
!Use only fittings "screwed plug B" as
per DIN 3852 (ISO 1179).
!Do not use sealing tape, copper rings or
coned fittings.
!Check sealing of the hydraulic
connections!
!Connection at mounting thread (1) (see
drawing page 2).
!The hydraulic intensifier can be directly
screwed into the fixture.

Target group of this
document
Provided use
Material damage
With hydraulic pressure very high
forces are generated. The fixture
or machine must be in the position
to compensate these forces.
Instructions for safe
operation
Material damage
Do not exceed maximum operating
pressure and maximum flow rate!
Pressure spikes have to be
avoided.
Function
Troubles of functioning
During operation there is a leakage;
therefore use in cycling mode is not
possible.
