Embodiment Construction

[0039] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0040] In order to make those skilled in the art better understand the embodiments provided by the present disclosure, the application background of the present disclosure is first introduced in detail.

[0041] The hydraulic system includes power components, actuators, control components, auxiliary components (also called accessories) and hydraulic oil. Among them, the function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, that is, the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The control components are various hydraulic valves. Hydraulic valve...

Abstract

The invention relates to a hydraulic oil temperature control system, a hydraulic oil temperature control method and a pump truck, and aims to control the heat dissipating capacity of hydraulic oil in a radiator by adjusting the rotating speed of a fan. The system comprises a temperature sensor, the fan, the radiator, a proportional overflow valve and a controller, wherein the proportional overflow valve is arranged on a pipeline through which a hydraulic oil tank conveys hydraulic oil to a hydraulic motor of the fan, and the controller is connected with the temperature sensor and the proportional overflow valve, wherein the temperature sensor is used for detecting temperature information of the hydraulic oil in the hydraulic oil tank; the controller is used for adjusting the flow of the hydraulic oil conveyed to the hydraulic motor of the fan by the hydraulic oil tank by controlling the opening degree of the proportional overflow valve according to the temperature information detected by the temperature sensor, and the flow of the hydraulic oil conveyed to the hydraulic motor is in positive correlation with the temperature of the hydraulic oil; and the fan is used for dissipating heat of the hydraulic oil flowing through the radiator.

Description

technical field [0001] The present disclosure relates to the technical field of engineering machinery, in particular, to a hydraulic oil temperature control system and a control method thereof, and a pump truck. Background technique [0002] The hydraulic system is a device that uses oil as the working medium and uses the pressure energy of the oil to operate the hydraulic actuator through the control valve and other accessories. The principle of the hydraulic system is to increase the force by changing the pressure. The hydraulic system includes power components, executive components, control components, auxiliary components (accessories) and hydraulic oil. Among them, hydraulic oil is the working medium for transferring energy in the hydraulic system, and hydraulic oil is divided into several categories such as mineral oil, emulsion and synthetic hydraulic oil. Hydraulic oil plays the role of energy transmission, system lubrication, anti-corrosion, anti-rust, cooling and...
