Hydraulic heat dissipation controlling system, method, device and equipment and engineering machine

Abstract

The invention provides a hydraulic heat dissipation controlling system, method, device and equipment and an engineering machine and relates to the technical field of engineering machines. The hydraulic heat dissipation controlling system comprises a hydraulic oil tank, a hydraulic oil radiator, a pressure sensor, a control unit, a first back pressure valve and an oil return block. The oil inlet end of the hydraulic oil radiator is provided with the pressure sensor, and the oil inlet end communicates with one end of the first back pressure valve. The other end of the first back pressure valve communicates with the first end of the oil return block. The second end of the oil return block communicates with a second oil return port of the hydraulic oil tank, and the third end of the oil returnblock communicates with the return oil output end of at least one hydraulic actuating mechanism. The pressure sensor is in communication connection with the control unit, and transmits the collectedpressure value of the oil inlet end of the hydraulic oil radiator to the control unit. The control unit is in communication connection with the first back pressure valve, and adjusts the first back pressure valve according to the pressure value. According to the hydraulic heat dissipation controlling system, method, device and equipment and the engineering machine, the pressure at the inlet end ofthe hydraulic oil radiator can be controlled, so that the heat dissipation efficiency of the hydraulic heat dissipation control system is improved, and the working efficiency of the engineering machinery is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hydraulic heat dissipation control system, method, device, equipment and construction machinery. Background technique [0002] In order to effectively avoid the engine "stall" caused by the impact of overload and impact load due to the abnormal sudden change of its working environment, the existing construction machinery generally adopts the technical scheme of hydraulic drive. At the same time, in order to effectively reduce the temperature of the oil circulated by the hydraulic system to ensure its normal operation, a hydraulic system radiator is generally used that combines the cooling part of the steering mechanism and the cooling part of the torque conversion mechanism. [0003] At present, the heat dissipation of the hydraulic system in construction machinery generally uses cold air to dissipate heat from the hydraulic oil radiator, and its hydraulic oil ra...
