Problems solved by technology

[0003] At present, the hydraulic oil used in hydraulic equipment mainly relies on natural cooling, and the cooling effect is relatively poor. Due to the increase in the temperature of the hydraulic oil, the hydraulic equipment fails frequently, which increases the failure rate and causes the hydraulic equipment to work unstable.

Abstract

The invention discloses a hydraulic oil cooling structure, which includes a water tank and a heat exchange tube. The upper and lower ends of the heat exchange tube are respectively connected with a liquid outlet pipe and a liquid return pipe. The hot liquid inlet, the upper part of the side wall at the other end of the water tank has a cold liquid inlet and the lower part has a hot liquid outlet, the cold liquid outlet is connected with the hot liquid inlet through a heat exchange tube, and the heat exchange tube is spirally wound around the axis of the heat exchange cylinder. On the outer peripheral wall, a corrugated board that divides it into two parts is installed in the box. The end of the corrugated board away from the cold liquid outlet is bent and then extends upward to connect with the inner wall of the box near the cold liquid inlet. The hydraulic oil in the high temperature state flows into the heat exchange cylinder from the liquid outlet pipe, and the hydraulic oil realizes the purpose of cooling the hydraulic oil through the heat exchange between the heat exchange cylinder and the heat exchange tube, and the cooled hydraulic oil flows from the The liquid return pipe returns to the hydraulic system to facilitate continued use.

Description

technical field [0001] The invention relates to cooling equipment, in particular to a hydraulic oil cooling structure. Background technique [0002] Hydraulic equipment refers to the device that transmits pressure through hydraulic oil and is the carrier of the hydraulic system. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. The function of hydraulic cylinder and hydraulic motor, the actuators of the hydraulic system, is to convert the pressure energy of the liquid into mechanical energy to obtain the required linear reciprocating motion or rotary motion. Hydraulic equipment has the characteristics of large transmission force, easy transmission and configuration, so it is widely used in industrial and civil industries. [0003] At present, the hydraulic oil used in hydraulic equipment mainly relies on natural cooling, and the cooling effect is relatively poor. Due to the in...
