Abstract

The invention belongs to the field of mechanical manufacturing and discloses an independent hydraulic oil grading cooling system and engineering machinery. The independent hydraulic oil grading cooling system comprises a radiator 1, cooling fans 2, hydraulic motors 3 and a controller 4, wherein the cooling fans 2 comprise a first cooling fan 5 and a second cooling fan 6; a cooling surface matched with the first cooling fan 5 and the second cooling fan 6 is arranged on the radiator 1; the cooling surface comprises a first temperature area and a second temperature area which are respectively matched with the first cooling fan 5 and the second cooling fan 6; the first cooling fan 5 and the second cooling fan 6 are respectively arranged on one sides of the first temperature area and the second temperature area, and are positioned on the same side of the radiator 1; the first cooling fan 5 and the second cooling fan 6 are respectively connected with the controller 4 through the hydraulic motors 3. According to the technical scheme provided by the invention, since an area partitioning and grading method is adopted for cooling the radiator, the mounting space is fully utilized, the cooling air loss is reduced, the ventilation and heat dissipation efficiency is improved, the service power of the fans is reduced, and the energy-conservation control is realized.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a cooling system, in particular to an independent hydraulic oil graded cooling system and engineering machinery. Background technique [0002] Large-scale construction machinery is the key equipment of large-scale open-pit mines or large-scale hydropower engineering sites. The quality of construction machinery depends on the heat dissipation performance of key components such as hydraulic systems and engines. In order to meet the heat dissipation requirements of large-scale construction machinery, it is necessary to add an independent hydraulic oil cooling system including radiators, cooling fans and drive control systems. [0003] Existing technical problems: [0004] In order to enhance the heat dissipation effect, the general hydraulic oil cooling device needs to arrange and combine several radiators and cooling fans. [0005] The existing cooling system has a...
