7.5 Mounting the servo-hydraulic actuator
7.5.1 Preparing the installation
1. Check the scope of delivery for completeness and damage in transit.
2. Compare the material number with the details in the order confirmation.
If the material numbers or denominations of the servo-hydraulic actuator and of
the drive controller do not correspond to those given in the order confirmation,
contact Bosch Rexroth Service for clarification, see
⮫
Chapter 16.1 “Service
and support” on page 77.
7.5.2 Mechanical mounting
WARNING
Improper mounting! Insufficient fixation or insufficient
stability may cause the servo-hydraulic actuator to
become loose and fall down. Consequently, hydraulic
fluid may leak and lead to personal injuries and/or
damage to property. Heavy servo-hydraulic actuators may
cause bruises or fatal injury.
−
Install the servo-hydraulic actuator completely
according to the mounting instructions by means of
suitable mounting aids.
WARNING
Accidental movement of the servo-hydraulic actuator
while it is being installed! Risk of injury! Danger of
crushing! Damage to property!
−
Keep the servo-hydraulic actuator in a stable and
secured position until it is fixedly mounted to the
mounting face provided at the customer’s end.
−
Be careful when installing the actuator.
NOTICE
Improper mounting of the servo-hydraulic actuator to the
customer’s equipment! Damage to property!
−
Mount the servo-hydraulic actuator so that the cyl-
inder piston rod, which is connected to the custom-
er’s equipment, is aligned and that there is no axial
offset.
−
Prevent transverse forces on the cylinder piston rod
and on the customer’s equipment.
The servo-hydraulic actuator has to be installed so that it is free from trans-
verse forces as far as possible. Any transverse forces have to be eliminated by
the customer by providing guides and making corresponding adjustments.
The piston rod and the customer valve have to be mounted in alignment.
Stroke length, loading and mounting have to be taken into account in order to
keep bending and buckling to a minimum in any stroke position.
●
Mount the servo-hydraulic actuator so that the load acts axially on the
center line of the cylinder.
●
The mounting faces and fastening elements on the customer equipment
have to be capable of absorbing the forces that occur.
The servo-hydraulic actuator should be installed complying with the mounting
and setting instructions of the customer.
●
Work carefully.
●
Check that the machine element, to which the servo-hydraulic actuator is
mounted, is secured against tilting.
●
Check whether the connection bores fit.
