Oil Temperature and Heat Loss
Flow through a pressure drop produces heat. Examine both heat generation and cooling to understand oil temperature.
What is happening technically?
Yaklaşık kısıcı kaybı P(kW) = Δp(bar) × Q(L/dk) / 600. Sürekli 30 bar farkla 20 L/dk geçen kısıcı yaklaşık 1 kW ısı üretir.
In practice
Continuous flow through a relief valve in standby can heat the oil even when the machine is not moving.

If movement, pressure or temperature changes, first identify the conditions in which the symptom occurs. Record existing gauge readings. Base maintenance or circuit examination on causes confirmed by measurements.
