Problems solved by technology

[0003] In the traditional cooling system, the cooling fan is usually installed on the engine. The change of the fan speed is corresponding to the change of the engine speed. The cooling effect is directly related to the engine speed. Therefore, the cooling system cannot meet all the working conditions of the system. Heat exchange requirements often cause overheating or overcooling of construction machinery engines, intercoolers, hydraulic operating systems, torque converters, etc.
Especially when the engine is under low-speed and high-torque conditions, due to the slow speed of the cooling fan and poor cooling effect, it often causes overheating; when the engine starts idling and the ambient temperature is low, it will cause overcooling
It cannot guarantee that the system will always work at the optimal operating temperature. In addition, when the engine speed is high, the fan speed is also high, which causes problems such as excessive noise caused by the fan. Therefore, it is necessary to improve

Abstract

The invention discloses an engineering machinery cooling system. The engineering machinery cooling system comprises a display, a controller, a sensor, a pump, a motor, a fan and a heat dissipating module, wherein an input end of the controller is connected with the sensor, and an output end is connected with the display and the pump; the display and the sensor are connected with the controller through circuits; the pump is connected with the controller by a pump speed adjusting signal; the motor is connected with the pump through a hydraulic pipe; the fan is arranged at the output shaft end of the motor; and the heat dissipating module is forcedly cooled by the fan. The engineering machinery cooling system can enable equipment to locate at the optimal working temperature, and has the advantages of energy conservation, emission reduction and noise reduction.

Description

technical field [0001] The invention relates to the technical field of construction machinery, and more specifically relates to a cooling system for construction machinery. Background technique [0002] Construction machinery is the general term for construction machinery used in engineering construction. It is widely used in engineering fields such as construction, water conservancy, electric power, roads, mines, ports, and national defense. During use, the engine, hydraulic operating system, torque-variable speed control system, booster system, etc. of construction machinery will generate a lot of heat. In order to ensure the normal operation of system equipment, cooling system or thermal system equipment must be used. [0003] In the traditional cooling system, the cooling fan is usually installed on the engine. The change of the fan speed is corresponding to the change of the engine speed. The cooling effect is directly related to the engine speed. Therefore, the cooling...
