OPERATING OIL TEMPERATURE CONTROLLER FOR HYDRAULIC DRIVE DEVICE |
摘要 |
<p>A control unit for controlling a flow rate control valve includes a first computing unit for determining an energy component that heats hydraulic oil, a first setting unit for setting a second relationship between a flow rate through an oil cooler and the energy component based on an experimentally or empirically known, first relationship between flow rate through the oil cooler and an amount of oil cooler heat radiation as derived by replacing the amount of oil cooler heat radiation in the first relationship to the energy component, and a second computing unit for determining the flow rate through the oil cooler based on the energy component determined by the first computing unit and the second relationship. The control unit controls the flow rate control valve according to the flow rate determined by the second computing unit.</p> |
