Abstract

The invention relates to the field of engineering machinery, in particular to an engineering machinery radiator system temperature regulation and control method, which comprises the following steps of: 1, setting a preset value T0 in a controller; 2, the temperature sensor collects oil temperature data T of the radiator core and sends the data T to the controller; 3, the controller compares the oil temperature data T sent by the temperature sensor with a preset value T0; if T is greater than T0, executing the step 4, and if T is greater than T0, executing the step 5; 4, the fan blade adjusting angle theta is calculated, the fan blade inclination angle is reduced according to the theta, and the step 2 is executed again after the next work cycle; 5, the fan blade adjusting angle theta is calculated, the fan blade inclination angle is increased according to the theta, and the step 2 is returned to wait for the next work cycle. According to the adjusting and controlling method, the fan blade inclination angle is adjusted according to the oil temperature and the water temperature in the radiator, so that the heat dissipation requirements of the radiator in different environments are met; and normal operation of the vehicle is ensured.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a temperature control method for a radiator system of construction machinery. Background technique [0002] Construction machinery such as excavators and loaders are widely used in civil construction, water conservancy projects and other basic constructions. Due to the complex movements of excavators and the huge power consumption during vehicle operation, the cooling system of the equipment is particularly important. [0003] The radiator is an important part of the cooling system. The existing radiator uses a cooling fan to accelerate heat dissipation. The cooling fan can speed up the air flow near the radiator, so that the heat in the radiator is released quickly. Therefore, the air flow near the radiator The faster the temperature, the higher the heat dissipation efficiency of the radiator. [0004] However, due to the wide range of application fields of excavators and ...
