Abstract

The invention provides an engineering machinery full hydraulic automatic air cooling system which is capable of achieving multipoint simultaneous control. The engineering machinery full hydraulic automatic air cooling system comprises a motor, a hydraulic oil pump, a hydraulic connection pipeline, a hydraulic motor, a fan, radiators, a plurality of groups of temperature control valves connected with each other in series, a hydraulic oil tank and circulatory systems, wherein the motor is connected with the hydraulic oil pump and drives the hydraulic oil pump, the oil tank is connected with an input end of the hydraulic oil pump through the connection pipeline, an output end of the hydraulic oil pump is connected with the hydraulic motor and input ends of the temperature control valves through the connection pipeline, the hydraulic motor and the temperature control valves are connected with the oil tank, a power output shaft of the hydraulic motor is connected with the fan, the fan rotates to conduct forced cooling of a radiator I of a circulatory system IV, a radiator II of a circulatory system V, and a radiator III of a system VI, and the circulatory system IV, the circulatory system V, and the system VI need cooling. The engineering machinery full hydraulic automatic air cooling system has the advantages of being simple in structure, low in volume, low in cost, high in cooling efficiency and capable of ensuring that each working system of an engineering machinery works well.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery cooling equipment, in particular to a fully hydraulic automatic air cooling system for engineering machinery. Background technique [0002] Due to energy shortage and environmental pollution, energy conservation and emission reduction have become the main concept and technical pursuit of the current manufacturing industry. Construction machinery is powered by diesel engines to complete driving and operations. Then the power system of the engine, the hydraulic transmission system of engineering operations, and the pitch changer The variable speed walking system, etc. must operate at a reasonable operating temperature in order to convert the minimum input energy into the maximum output efficiency, so as to achieve energy saving and emission reduction. The task of the automatic cooling system of construction machinery is to ensure that the fans of each working system do not rotate when ...
