Example 1
Fig. 1 is a flowchart of an excavator intake grid control method provided in embodiment 1 of the present invention, where the method is applied to an excavator provided with an intake grid of a motor opening and closing structure, where the intake grid is used for supplying air to a hydraulic oil radiator, and the method includes the following steps:
step S11: the method comprises the steps of obtaining the hydraulic oil temperature of the excavator, and judging whether the hydraulic oil temperature is within a preset temperature range.
The embodiment of the invention is mainly applied to the excavator provided with the air inlet grid and the hydraulic oil radiator, wherein the air inlet grid is mainly used for supplying air to the hydraulic oil radiator in the excavator, so that the radiator can exchange heat with the outside and transmit the heat to the outside of the excavator, and the effect of radiating the hydraulic oil is achieved. The temperature of the hydraulic oil of excavator can influence the work efficiency of excavator, wherein, at the beginning of the start-up of excavator, because the hydraulic oil temperature is lower, the oil return resistance can be greater than the opening pressure of oil filter core bypass valve, makes the bypass valve constantly open and leads to during the outside pollutant gets into hydraulic oil to when the hydraulic oil temperature is lower, can make the viscosity increase of hydraulic oil, lead to hydraulic system's energy loss great. The temperature of the radiator in the excavator can be controlled by controlling the air inlet grid, so that the temperature of the hydraulic oil is controlled within a proper range, the energy efficiency of the excavator is improved, and the pollution of the hydraulic oil is reduced.
In the embodiment of the invention, the excavator is provided with the oil temperature collector, and the hydraulic oil temperature is collected through the oil temperature collector, wherein the oil temperature collector is provided with a plurality of oil temperature collectors, for example, the oil temperature collectors can be arranged in a hydraulic oil radiator, and also can be arranged in each flow direction path of each hydraulic pump or hydraulic oil, so that the hydraulic oil temperature of each position in the excavator can be collected in real time, and the accuracy of subsequent temperature judgment and air inlet grid regulation is improved. For example, an oil temperature acquisition application program may be provided in the control system of the excavator, and the oil temperature acquisition application program is immediately started in the control system after the excavator is started, and the controller of the excavator controls the oil temperature acquisition device to acquire the hydraulic oil temperature in real time.
In the embodiment of the invention, after the real-time hydraulic oil temperature is collected, whether the hydraulic oil temperature is in a preset temperature range or not is judged, namely whether the hydraulic oil temperature is in a proper range or not is judged, so that the energy efficiency of the excavator is ensured and the pollution of the hydraulic oil is avoided. The process of determining whether the hydraulic oil temperature is within the preset temperature range may be implemented by using an algorithm or an application program, for example, the application program for determining the temperature may be stored in advance in the excavator control system, and after the real-time hydraulic oil temperature is obtained, it may be determined whether the real-time hydraulic oil temperature is within the preset temperature range. The preset temperature range may be, for example, greater than or equal to 40 degrees and less than or equal to 60 degrees, the preset temperature range is related to physical properties and characteristics of hydraulic oil, and a user may adjust the preset temperature range according to different hydraulic oils, which is not limited herein.
Step S12: and when the hydraulic oil temperature is determined to be within the preset temperature range, calculating the opening and closing amplitude of the air inlet grid according to the hydraulic oil temperature.
In the embodiment of the invention, after the hydraulic oil temperature is determined to be within the preset temperature range, the opening and closing amplitude of the grid is calculated according to the hydraulic oil temperature so as to control the air output of the hydraulic oil radiator, so that the temperature of the hydraulic oil radiator is maintained within the proper temperature range. The opening and closing range of the intake grille may be adjusted according to the temperature trend, for example, when the temperature of the hydraulic oil is detected to have a trend of decreasing, the opening range of the intake grille may be decreased to decrease the air blowing amount of the radiator, and when the temperature of the hydraulic oil is detected to have a trend of increasing, the opening range of the intake grille may be increased to increase the air blowing amount of the radiator.
In the embodiment of the invention, an algorithm or an application program can be arranged in the excavator control system for calculating the opening and closing amplitude of the air inlet grid, for example, the application program can be arranged in the excavator control system, the excavator is operated after being started, and when the hydraulic oil temperature of the excavator works in a preset temperature range, the current oil temperature is obtained to calculate the opening and closing amplitude of the air inlet grid so as to control the motor of the air inlet grid and drive the air inlet grid to be opened to the corresponding amplitude.
