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 hSmax = 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.
