Temperature based power control for pump |
摘要 |
<p>In a construction machine according to the present invention wherein there is made an engine speed sensing control to control a pump horsepower in accordance with an engine speed of an engine. there is performed, in a low temperature condition with hydraulic oil temperature not reaching a preset temperature, a low temperature horsepower control involving setting the pump horsepower lower than at room temperature which is not lower than the preset temperature to lighten a burden on the engine. With this control, it is possible to prevent the occurrence of engine overtorque and hunting at a low temperature. <IMAGE></p> |
