Even when an oil analysis is returned with unsatisfactory results, it is not always necessary – or even desirable – to replace the oil. As long as the oil has not lost viscosity and has not been damaged by overheating, it can be reclaimed by flushing the system. When the oil in the reservoir is merely replaced, several gallons of bad oil are left in the lines and components – as much as

Troubleshoot Hot Hydraulics - Efficient Plant

When a hydraulic system is designed, the reservoir and heat exchangers are sized to remove that heat—some of which is allowed to dissipate through the reservoir walls to the atmosphere. “Heat exchangers, if properly sized,” Smiley noted, “should remove the balance of the heat and allow the system to operate at approximately 120 F.”
