Automatic circulation temperature rising and cooling system of excavator and control method thereof
The invention discloses an automatic circulation temperature rising and cooling system of an excavator and a control method thereof, and belongs to the technical field of engineering machinery. The cooling system overcomes the defects that a traditional cooling system of the excavator in the prior art is low in efficiency caused by low labor intensity of a driver and long heating process time. The main body structure of the system comprises a temperature sensor, a main pump unit, a main control valve unit, a controller, a circulation temperature rise unit, a power compensation unit, an auxiliary cooling unit, a return oil distribution unit and a circulation cooling unit, the oil suction end of the main pump unit is connected with a hydraulic oil tank, and the oil outlet end of the main pump unit is connected with the oil inlet end of the main control valve unit, the circulation temperature rise unit and the auxiliary cooling unit. The oil return end of the main control valve unit is connected with an oil inlet of the oil return distribution unit, an oil outlet of the oil return distribution unit is connected with the circulating cooling unit, the auxiliary cooling unit supplies stored energy to the circulating cooling unit, and an oil outlet of the circulating cooling unit is connected with a hydraulic oil tank. The invention is mainly applied to engineering machinery such as excavators.
