What’s the most common problem with hydraulics?
Overheating,
It’s a simple problem really. If you understand percentages – and I know you do, then overheating problems are easy to get a handle on.
You see, it’s a balancing act between the percentage of input power lost to heat and the percentage of heat dissipated by the system – mainly the heat exchanger.
Take a system with an input power of 100 kilowatts.
If it’s 80 percent efficient, it’s creating 20 kilowatts of heat load.
If the exchanger is dissipating 20 kilowatts of heat then a stable operating temperature will be maintained.
If the system starts to overheat, then either:
- The system is no longer 80 percent efficient; or
- The exchanger is no longer dissipating 20 kW of heat.
It’s that simple.
