Abstract

The invention provides a hydraulic oil tank, a temperature control system and a temperature control method, and relates to the technical field of hydraulic equipment. The hydraulic oil tank, the temperature control system and the temperature control method aim at solving the technical problem that the use of engineering machinery and the safety of an overall hydraulic system are influenced due toover-high temperature of hydraulic oil to a certain extent. The invention provides the hydraulic oil tank which comprises an oil tank body and a temperature control mechanism, wherein a first oil inlet and a second oil inlet are formed in the oil tank body, a partition plate is arranged in the oil tank body and divides the interior of the oil tank body into a main oil cavity and an auxiliary oil cavity, the first oil inlet communicates with the main oil cavity, the second oil inlet communicates with the auxiliary oil cavity, a first oil outlet is formed in the auxiliary oil cavity, a control valve is arranged in the first oil outlet, the control valve can block or conduct the auxiliary oil cavity and the main oil cavity, a second oil outlet is formed in the oil tank body and communicates with the main oil cavity, the temperature control mechanism is arranged in the main oil cavity and used for monitoring the oil temperature in the main oil cavity and controlling opening and closing ofthe control valve.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a hydraulic oil tank, a temperature control system and a temperature control method. Background technique [0002] The hydraulic oil tank is often faced with problems such as high temperature during the use of construction machinery such as excavators, resulting in excessively high hydraulic oil temperature, which affects the use of construction machinery and the safety of the entire hydraulic system. [0003] Existing ways to lower the oil temperature of the hydraulic oil usually adopt the method of adding heat dissipation structure externally to improve the heat dissipation effect. This method not only takes up space, but also increases the use cost. [0004] Therefore, it is urgent to provide a hydraulic oil tank, a temperature control system and a temperature control method to solve the problems existing in the prior art to a certain extent.
