3.7.3.2 Mounted oil supply system with water-oil cooler
Introduction
Depending on the order specification, an oil supply system with water-oil cooler can be used.
This oil cooling system is mounted on the gear unit.
Principle of operation
The water-oil cooler is used to cool the gear unit oil; water is used as coolant.
For certain applications, a motor pump can be used instead of a flange pump.
A mounted oil supply system with water-oil cooler can include the following components:
● Water-oil cooler
● Flange pump
● Oil filter (double change-over filter)
● Pressure monitor
● Piping
The operating company must establish the cooling water connection required.
Note
Observe the flow direction of the pump
When connecting the valves, observe the flow direction of the pump.
Refer to the pump operating instructions in the complete gear unit documentation to ascertain
whether the flow direction of the pump used depends on the direction of rotation.
Improper use can damage the gear unit. Be sure to take the following precautions:
● Ensure that the cooling water pressure is a maximum of 8 bar.
● Maintain the specified flow direction of the water-oil cooler so that an optimum cooling power
is achieved. Do not interchange the cooling water intake and outlet.
● If there is a risk of freezing temperatures, drain the cooling water out of the coil and blow the
coil out with compressed air to remove any water residue.
WARNING
Risk of eye injury from compressed air
Water residue and dirt particles can cause damage to eyes.
Wear suitable safety goggles.
