26/60 Installation
Bosch Rexroth AG
, A10VGT Series 11, RE 92770-01-B/11.2016
7 Installation
Prior to installation, the following documents must be to hand:
•
Installation drawing for axial piston unit (can be obtained from your contact
at Bosch Rexroth)
•
Hydraulic circuit diagram for the axial piston unit (in the installation drawing)
•
Hydraulic circuit diagram for the machine/system (available from the machine/
system manufacturer)
•
Order confirmation (contains the order-related technical data for your axial
piston unit)
•
Data sheet for the axial piston unit (contains the permissible technical data)
7.1 Unpacking
The axial piston unit is delivered in a corrosion protection film made of polyethylene
material (PE).
CAUTIOn!
Danger from parts falling out!
Improperly opening the packaging can result in parts falling out, which can be damaged
or cause injury.
▶
Place the packaging on a level, solid surface.
▶
Only open the packaging from the top.
▶
Remove the packaging from the axial piston unit.
▶
Check the axial piston unit for transport damage and completeness, see Chapter 4
“Scope of delivery” on page 18.
▶
Dispose of the packaging material according to the national regulations in your
country.
7.2 Installation conditions
The installation location and position of the axial piston unit essentially determine
the procedures during installation and commissioning (such as when filling and air
bleeding the axial piston unit).
▶
Fix the axial piston unit so that the expected forces and torques can be transferred
without any danger. The machine/system manufacturer is responsible for
dimensioning the fasteners.
▶
Observe the permissible radial forces on the drive shaft when transferring
input/output drive with radial load (belt drives). If necessary, the belt pulley
must be stored separately.
▶
Make sure that the axial piston unit is air bled and filled with hydraulic fluid
during commissioning and operation. Do this also after relatively long standstill
periods, since the axial piston unit may drain through the hydraulic lines.
▶
The leakage in the housing area must be directed to the reservoir via the highest
drain port. Use the line size which is appropriate for the port.
▶
Avoid using a check valve in the drain line.
▶
To keep noise down, decouple all connecting lines from all vibration-capable
components (e.g. reservoir) using elastic elements.
▶
Make certain that the suction, drain, and return lines flow into the reservoir
below the minimum fluid level in all operating conditions. This will prevent air
from being drawn in and foam from being formed.
