START IMPROVING SYSTEM WITH LOW TEMPERATURE FOR A SMALL EXCAVATOR |
摘要 |
PURPOSE: A start-up improvement system with low temperature for a small excavator is provided to prevent start-up from becoming uncontrollable when an engine is started by restoring oil to a tank. CONSTITUTION: A start-up improvement system with low temperature for a small excavator comprises a hydraulic pump(P), a drive motor(410), and a second valve(430). The hydraulic pump flows in oil accepted in an oil tank(T) using the power of an engine(E) and supplies the hydraulic oil to the drive motor. The drive motor is rotated by receiving the hydraulic oil. The second valve is formed in a driving path(400) where the hydraulic oil flows from the hydraulic pump to the drive motor and opens and closes the driving path. |
