Carrier hydraulic oil
2155E STD
Note: We strongly recommend the use of different hydraulic oils in the summer and
in the winter if there is an average temperature difference of more than 35 °C (63
°F). The correct hydraulic oil viscosity is thus ensured.
SPECIAL OILS
In some cases special oils (for example biological oils and non-inflammable oils)
can be used with hydraulic hammers. Observe the following aspects when
considering the use of special oils:
■
The viscosity range in the special oil must be in the given range (20-1000 cSt)
■
The lubrication properties must be sufficient
■
The corrosion resistance properties must be good enough
Note: Although a special oil could be used in the carrier, always check its suitability
with the hammer due to high piston speed of the hammer. Contact the oil
manufacturer or your local dealer for more information about special oils.
2.2 OIL COOLER
The correct place to connect the hammer return line is between the oil cooler and
the main filters. The hammer return line should not be connected before the oil
cooler. Routing the hammer return flow through the cooler, might damage either the
cooler, due to pulsating flow, or the hammer, due to increased back pressure.
The carrier hydraulic system must be able to maintain the temperature within an
acceptable level during the hammer operation. This is for two reasons.
1. Seals, wipers, membranes and other parts manufactured from the corresponding
materials can normally stand temperatures up to 80 °C (176 °F).
2. The higher the temperature is, the less viscous the oil gets thus losing its
capability to lubricate.
■
The hammer circuit pressure relief valve is not open when the hammer is
operated.
■
The hammer circuit pressure drops are reasonable. Less than 10 bar (145 psi) in
the pressure line and less than 5 bar (75 psi) in the return line.
■
Hydraulic pumps, valves, cylinders, motors etc. and hammer do not have
internal leakages.
If all of the above mentioned things are in order, and the temperature of the
hydraulic oil still tends to be too high, extra cooling capacity is needed. Consult the
carrier manufacturer or dealer for details.
