Desired Reservoir Temperature
Return Line Cooling: Desired temperature is the oil temperature leaving the
cooler. This will be the same temperature that will be found in the reservoir.
Off-Line Recirculation Cooling Loop: Desired temperature is the oil
temperature entering the cooler. In this case, the oil temperature change
must be determined so that the actual oil leaving temperature can be found.
Calculate the oil temperature change (oil T) with this formula:
Oil T = (BTU’s/Hr.) / (GPM Oil Flow x 210).
To calculate the oil leaving temperature from the cooler, use this formula:
Oil Leaving Temp. = Oil Entering Temp – Oil T.
This formula may also be used in any application where the only temperature
available is the entering oil temperature.
Oil Pressure Drop: Most systems can tolerate a pressure drop through the
heat exchanger of 20 to 30 PSI. Excessive pressure drop should be avoided.
Care should be taken to limit pressure drop to 5 PSI or less for case drain
applications where high back pressure may damage the pump shaft seals.
Oil Temperature
Typical operating temperature ranges are:
Hydraulic Motor Oil
110° - 130°F
Hydrostatic Drive Oil
130° - 180°F
Bearing Lube Oil
120° - 160°F
Lube Oil Circuits
110° - 130°F
