Embodiment 1

[0040] see figure 2 As shown, the present embodiment provides a self-adaptive independent cooling method for grabbers and excavators, comprising the following steps:

[0041] 1) Determine the fan speed requirements corresponding to various temperatures according to the air intake temperature, cooling water temperature, hydraulic oil temperature and ambient temperature after the intercooler;

[0042] specific:

[0043] First, establish the mapping relationship between the intake air temperature, cooling water temperature, hydraulic oil temperature, and ambient temperature after the intercooler and the fan speed requirements. The mapping relationship is a parameter data table formulated by the engine manufacturer according to the national standard. The parameter data table includes The fan speed corresponding to the corresponding temperature value is shown;

[0044] Then, through existing technical means, such as temperature sensor monitoring, real-time data of intake air tem...

Abstract

The invention relates to the technical field of cooling control, and provides a self-adaptive independent cooling method for a material grabbing machine and an excavator. The method comprises the following steps of 1) determining fan rotating speed requirements corresponding to various temperatures according to the rear air inlet temperature of an intercooler, the cooling water temperature, the hydraulic oil temperature and the environment temperature; 2) comparing the fan rotating speed requirements to determine the maximum fan rotating speed requirement; and 3) controlling the fan rotating speed according to the maximum fan rotating speed requirement. The invention further discloses a cooling system of the self-adaptive independent cooling method for the material grabbing machine and theexcavator. The cooling system comprises a controller, a plurality of temperature sensors connected with the controller, a control valve set connected with the controller, a hydraulic motor connectedwith the control valve set and a fan connected with the hydraulic motor. According to the method and the system, the fan rotating speed requirement of the rear air inlet temperature of the intercooler, the cooling water temperature, the hydraulic oil temperature and the environment temperature are fully and comprehensively considered, the power consumption of the fan is reduced, the cooling efficiency of the cooling system is improved, and the fan reverse rotation dust removal function is achieved.

Description

technical field [0001] The invention relates to the technical field of cooling control, in particular to a self-adaptive independent cooling method and system for a material grabber and an excavator. Background technique [0002] In order for the vehicle to run normally, the engine needs to be cooled, and water cooling is generally used. This water-cooling method needs to set up a radiator, which is connected to the engine through a circulation pipe, and water is injected into the circulation pipe during operation, and the water is used to conduct heat. In order to ensure the heat dissipation effect, a fan needs to be provided to blow air on the surface of the radiator. [0003] The existing patent CN104863685A, the patent name "A method and system for controlling electric fans for vehicles", includes steps: 1. Determine the engine air volume requirement according to the engine water temperature, current vehicle speed and ambient temperature; 2. Obtain one or more auxiliary...
