58/78 Installation
Bosch Rexroth AG, Control block SB24/34, RE 66170-B/2019-05-15
7.6.5 Hydraulic connection of the control block/control block segment
CAUTION
Dangerous movements of the hydraulic consumers!
Risk of injury due to incorrect pin assignments or mixed up cable connectors
because of inadvertent consumer movement!
▶
Make sure that all the pipes and/or hoses have been attached to the correct
ports and have not been mixed up under any circumstances.
▶
After connection is completed, make sure that the cable connectors are
correctly assigned to the respective solenoid.
NOTICE
Damage due to improper installation!
When installing hydraulic lines and hoses under mechanical stress, they are
exposed to additional mechanical forces during operation which reduce the
service life of the control block/control block segment and the entire machine.
▶
Install hydraulic lines and hoses without mechanical stress.
The machine/system manufacturer is responsible for dimensioning of the lines. The
control block/control block segment must be connected to the rest of the hydraulic
system in accordance with the hydraulic circuit diagram of the machine/system
manufacturer.
The ports and mounting threads are designed for the maximum pressure specified
in the data sheet. The machine/system manufacturer is required to ensure that the
connecting elements and lines correspond to the specified application conditions
(pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.
Only connect hydraulic lines that are suitable for the port of the control block/
control block segment (pressure level, size, system of units).
Observe the following information when routing hydraulic lines.
• Lines and hoses must be installed without pre-charge pressure so that no further
mechanical forces are applied during operation that will reduce the service life of
the control block/control block segment and possibly of the entire machine.
• Only use original Rexroth seals.
• When routing the lines, always ensure that the control block/control block segment
is filled with hydraulic fluid and not discharged even during long standstill.
For an overview of line connections, refer to the respective data sheet and the offer
drawing.
• Fittings with seal:
– O-ring ISO 6149-1
– Cutting edge
DIN 3852-1 or DIN 3852-2
• Lightly grease the fitting and tighten clockwise.
