10 Maintenance and repair
Maintenance tasks (inspection, maintenance, repair) must be defined according
to system-specific requirements, operating conditions (pressures, temperatures,
environmental conditions) and the operating life (duty cycle, cycle times, shift
operation).
The declarations made in this chapter are based on climate conditions in Central
Europe and common environments in the metal-processing industry.
A negative trend of test parameters like hydraulic fluid temperature, short
replacement intervals of filter elements or noise indicate changes. The
troubleshooting matrix in chapter 15, table 11, provides support for the
identification of issues.
Slow increase in temperature and/or shorter filter replacement intervals indicate
potential wear at the pump, seals as well as aging of hydraulic fluid and should
initiate inspection of all relevant components.
Immediate strong increases in temperature are alarming and require immediate
inspection of the machine/system.
For further information on the scope and time intervals for maintenance and
repair of the overall machinery/system, please refer to the operating instructions
of the machine/system manufacturer.
10.1 Cleaning and care
For cleaning and care of the hydraulic power unit, observe the following:
▶
Make sure that all seals and electric plug-in connections are firmly fitted to
prevent the penetration of cleaning agents and/or humidity into the hydraulic
power unit.
▶
Do not use aggressive cleaning agents for cleaning. Clean the hydraulic power
unit using a suitable cleaning liquid.
▶
Do not use a high-pressure washer.
▶
Do not use compressed air for the cleaning at functional interfaces.
▶
Remove external coarse dirt and keep sensitive and important parts like electrical
connections clean.
▶
For the cleaning, use a damp, non-linting cloth or residue-free industrial wipes.
