Table 15: Axial piston unit malfunction table
Malfunction Possible cause Remedy
No orinsufficient flow Insufficient air bleeding ofthehydraulic system Fill the axial piston unit, suction line for the
hydraulic pump and the reservoir
Completely air bleed the axial piston unit and
hydraulic system
Faulty mechanical drive (e.g.defective coupling) Contact machine/system manufacturer
Drive speed too low Contact machine/system manufacturer
Insufficient suction conditions, e.g.insufficient
dimensioning ofthesuction line, viscosity
ofthehydraulic fluid too high, suction height
too high, suction pressure too low, foreign
particles inthe suction line, impermissible filter
inthe suction line
Machine/system manufacturer: Check the
system, e.g.optimize inlet conditions, use
suitable hydraulic fluid
Fill the suction line with hydraulic fluid
Remove foreign particles from the suction line
Hydraulic fluid not inoptimal viscosity range Machine/system manufacturer:
Check temperature range and use suitable
hydr
aulic fluid
Insufficient pilot pressure orcontrol pressure Check pilot pressure orcontrol pressure
