Rexroth IndraDyn A
Application Notes
9-9
Coolants
MAF motors
must
always
be operated with an external cooling system.
The energy losses of the motor, P(v), are dissipated through the cooling
system. Accordingly, MAF motors may only be operated if proper coolant
flow is ensured. The cooling system has to be rated by the machine
manufacturer in such a way that all requirements regarding flow,
pressure, purity, temperature gradient etc. are maintained at all times.
CAUTION
Impairment or loss of motor, machine or
cooling system!
⇒
Consider absolutely the motor data and the
explanations and conceptions of the cooling systems
in the documentation ”Liquid cooling, dimensioning,
selection”, MNR R911265836.
⇒
Consider the manufacturer instructions at
construction and operation of cooling systems.
⇒
Do not use any lubricants or cutting lubricants from
operating processes.
All details and technical data refer to water as a coolant. When using
other coolants, these data are no longer valid and must be recalculated.
Cooling using tap water is not recommended. Hard water can cause
deposits or corrosion and damage the motor and the cooling system.
For corrosion protection and for chemical stabilization, the cooling water
must have an additive which is suitable for mixed-installations with the
materials acc. to Fig. 9-13.
The utilization of aggressive coolants, additives, or cooling lubricants can
cause irreparable motor damages.
⇒
Use a recirculating system with a fine filter
≤
100 µm.
⇒
Consider the environmental protection and waste disposal
instructions at the place of installation when selecting the coolant.
Aqueous solutions ensure a reliable corrosion protection without
significant changes to the physical property of the water. The
recommended additives contain no harmful materials to water.
Corrosion protection oils for coolant systems contain emulsifiers which
ensure a fine allocation of the oil in the water. The oily components of the
emulsion protect the metal surface of the coolant duct against corrosion
and cavitation. Herewith, an oil content of 0.5 – 2% by volume has proved
itself.
If the corrosion protection oil must not only provide corrosion protection
also provide lubrication of the cooling pump, then the oil content of 5% by
volume is necessary.
⇒
Note the regulations of the pumping manufacturer!
