Description

Technical Field

[0001] The utility model relates to the technical field of temperature detection, in particular to a protection structure of an axle temperature sensor. Background Art

[0002] Temperature sensors are widely used in brine units and process gas compressor units. The accuracy of the temperature sensor value directly affects the use and efficiency of the equipment. When measuring temperature, the existing temperature sensors have their temperature measuring part directly in contact with the measured medium.

[0003] The existing Chinese utility model patent with reference announcement number CN209131847U discloses a temperature sensor protection structure, including a protection tube and a temperature sensor sleeved on the protection tube; the protection tube includes a first tube body and a second tube body connected to each other; the inner cavity of the protection tube is divided into a fixed section and a protection section connected to each other; a step surface is formed between the fixed section and the protection section; an end of the fixed section away from the protection section passes through the first tube body; the temperature sensor includes a junction box, a non-temperature sensing part, a connecting part and a temperature measuring part connected in sequence; the junction box is located outside the protection tube, the connecting part extends into the fixed section, and is threadedly connected to the protective tube part corresponding to the fixed section; the step surface faces the connecting part, and a connecting part is provided between the connecting part and the step surface

[0004] There is a sealing gasket, and an insulation layer is provided on the protection section corresponding to the side of the sealing gasket facing the step surface; the temperature measuring part is located in the protection section to be protected; heat transfer oil is filled between the temperature measuring part and the second cylinder, and the temperature is transferred to the temperature measuring part through the heat transfer oil, so that the temperature sensor can accurately measure the temperature.

[0005] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that a sensor is needed to detect the temperature of the upper end of the rotating shaft when the rotating shaft is used. The traditional sensor is directly installed on the side end of the rotating shaft, which causes the subsequent upper end temperature of the rotating shaft to be too high, causing the front end detection head of the sensor to be damaged by high temperature, affecting the use of the entire sensor. There is no protective device on the upper end of the sensor, causing the subsequent sensor to be exposed to sparks or collisions, resulting in a reduction in the overall life of the subsequent sensor. The existence of these problems affects the use of the device. Utility Model Content
