Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The normal working temperature of the hydraulic oil of the excavator is about 60 degrees. If the temperature of the hydraulic oil is too high, the following problems will occur: (1) The viscosity of the hydraulic oil decreases, which increases the flow of the oil through the throttle hole or the slit valve. Affect the stability of work; (2) After the oil temperature rises and ...

Abstract

The invention provides a medium temperature control system and method and an engineering vehicle. The medium temperature control system comprises a temperature sensor, a control module, an engine, a fan and a radiator; the temperature sensor is used for acquiring medium temperature; the control module is used for controlling engine speed and fan air volume according to the medium temperature; thefan is used for providing air volume for the radiator so that the radiator can reduce the medium temperature; the control module is further used for comparing the medium temperature with a preset temperature value, and when the medium temperature is larger than or equal to the preset temperature value, the engine speed is controlled to rise to a first rotating speed threshold value; when the medium temperature is smaller than the preset temperature value, and an engine is controlled to work at the preset rotating speed value of a current gear; and the preset rotating speed value of the currentgear is smaller than the first rotating speed threshold value. According to the medium temperature control system and the method and the engineering vehicle, and the equipment cost and the failure rate can be reduced while the medium temperature is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to a medium temperature control system and method and an engineering vehicle. Background technique [0002] When engineering vehicles (such as excavators) work in low gears, the temperature of the medium (such as hydraulic oil, water) rises. If the temperature of the medium is too high, it will not only affect the stability of the excavator, but also increase mechanical wear and shorten the use of components. life. Therefore, in practical applications, it is necessary to adjust the temperature of the medium when the excavator is working in a low gear, so that the excavator can work safely and efficiently. However, in the prior art, the temperature of the medium is usually adjusted through an external cooling system, and the cooling system adds a variable pump, a motor and a control system, thereby increasing equipment costs and failure rates.
