Hydraulic independent heat dissipation electric control system of excavator and heat dissipation method of hydraulic independent heat dissipation electric control system
The invention relates to a hydraulic independent heat dissipation electric control system of an excavator. The motor is suitable for driving the fan to rotate; the oil inlet pipe and the oil outlet pipe are connected with the motor and the oil tank; the gear pump is arranged on the oil inlet pipe; the reversing valve is connected with an outlet of the oil inlet pipe and an inlet of the oil outlet pipe and is suitable for controlling the motor to rotate forwards and backwards; the proportional valve is arranged on the oil inlet pipe; the first branch is connected with the oil inlet pipe and the oil outlet pipe, and a reversing overflow valve is arranged on the first branch; the temperature sensor is arranged at an outlet of the oil outlet pipe; the hydraulic independent heat dissipation system of the excavator is simple in structure, good in effect and low in cost, it is guaranteed that the temperature of oil can be kept at a safe numerical value when the system is at different engine rotating speeds, and reverse rotation of the fan can be achieved without stopping the engine; and through the cooperation of the compensation valve and the hydraulic control valve, the rotating speed of the fan motor is stable, and the energy-saving performance and the starting and stopping smoothness of the motor are achieved.
本发明是一种挖掘机液压独立散热电控系统，包括：油箱；马达，其适于驱动风扇转动；进油管、出油管，其连接所述马达、油箱；齿轮泵，其设置在所述进油管上；换向阀，其连接所述进油管出口、出油管入口处，其适于控制所述马达正反转；比例阀，其设置在所述进油管上；第一支路，其连接所述进油管、出油管，其上设置有换向溢流阀；温度传感器，其设置在所述出油管出口处；本装置结构简单、效果良好、成本低廉的挖掘机液压独立散热系统，保证了系统在不同的发动机转速下，都能使油液温度保持在一个安全的数值，并且能实现发动机不停机风扇反转；并且通过补偿阀和液控阀的配合，使风扇马达转速平稳，兼具节能性和马达启停的平顺性。
