Installation instructions General:
During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This must also be observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines.
Particularly in the installation position "drive shaft upwards" filling and air bleeding must be carried out completely as there is, for example, a danger of dry running.
The case drain fluid in the housing must be directed to the reservoir via the highest available drain port (T1,T2).
If a shared drain line is used for several units, make sure that the respective case pressure is not exceeded. The shared drain line must be dimensioned to ensure that the maximum permissible case pressure of all connected units is not exceeded in any operating conditions, specifically on cold start. If this is not possible, separate reservoir lines must be laid as required.
To achieve favorable noise values, all connecting lines should be decoupled by using elastic elements and above-reservoir installation is to be avoided.
In all operating conditions, the suction and drain lines must lead into the reservoir below the minimum fluid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 800 mm. The minimum suction pressure at port S must also not fall below 0,8 bar absolute during operation and during cold start.
When designing the reservoir, ensure adequate space between the suction line and the drain line.This provides a slow-down and desgasification of the fluid and prevents that heated return flow is being drawn directly back into the suction line.
Installation position
See the following examples 1 to 8.
Further installation positions are possible upon request. Recommended installation position: 1 and 2.
Below-tank installation (standard)
Below-tank installation is at hand if the axial piston unit is installed below the minimum liquid level outside the tank.
Above-reservoir installation:
Above-reservoir installation means that the axial piston unit is installed above the minimum fluid level of the reservoir.
Recommendation for installation position 8 (drive shaft upward): A check valve in the drain line (cracking pressure 0,5 bar) can prevent draining of the pump housing.
General project planning notes:
The axial piston unit is designed to be used in open circuits.
The project planning, installation and commissioning of the axial piston unit require the involvement of qualified skilled personnel.
Before using the axial piston unit, please read the corresponding instruction manual completely and thoroughly. If necessary, request it from Bosch Rexroth.
Before finalizing your design, request a binding installation drawing.
The specified datas and notes must be observed.
