Air-cooled oil cooling system capable of automatically detecting temperature

Abstract

The invention relates to an air-cooled oil cooling system capable of automatically detecting the temperature. The system is characterized in that a cooler is mounted on the outer side, facing an oil tank, of a fan casing; at least on fan is mounted on the inner side, facing the oil tank, of the fan casing; a secondary cooling pipeline provided with multiple bends in the vertical direction is arranged on the oil tank upper end surface between an oil supply power source and the fan casing; output ends of three temperature sensors are connected with an input / output interface of a central control module; the input / output interface of the central control module is connected with a control terminal of a circulating power source. According to the air-cooled oil cooling system capable of automatically detecting the temperature, the cooler and the secondary cooling pipeline realize cooling on two sides, so that the temperature of oil is sufficiently decreased; the temperature of three positions can be transmitted to an automatic control device at any time by the three temperature sensors, the automatic control device controls the circulating power source to increase or decrease flow velocity of oil, accordingly, the circulating power source works according to the actual temperature, energy is saved, scene alarm and monitoring center alarm can be performed when the temperature is overhigh, and work safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of improving the oil cooling structure of a hydraulic station, in particular to an air-cooled oil cooling system with automatic temperature detection. Background technique [0002] In the hydraulic station, the working temperature of the oil is a parameter that needs to be paid attention to at all times. The existing heat dissipation structures include air cooling and water cooling. The air cooling structure is relatively simple and does not require auxiliary equipment, which makes the movement of the hydraulic station convenient, so it has been obtained. widely used. The existing air-cooled structure is: including the fan casing 4, the radiator 3 and the circulating power source 10, all of which are installed on the upper surface of the fuel tank 1, the fan casing is installed toward the inside of the fuel tank, and the fan casing is installed toward the outside of the fuel tank At least one fan 7, when th...

Problems solved by technology

In actual use, it is found that since the radiator is located above the fuel tank, the cold air sucked by the outside fan performs heat exchange with the radiator, and the hot air is blown out towards the top of the fuel tank, which not only affects other hydraulic components on the upper end of the fuel tank, but also The heat dissipation effect of the fan needs to be improved. At the same time, the fan in the air cooling keeps rotating at a high speed, which wastes energy when the oil temperature is not very high.
