Embodiment 1

[0022] Such as Figure 1~4 shown. A device for measuring the oil temperature of a cylinder seat, comprising a thermocouple 1, a screw plug 2 and an adhesive 3. Among them, the thermocouple 1 is installed in the thermocouple installation hole at the center of the screw plug 2, and the lead-out wire end of the thermocouple is located outside the end face of the screw plug, and the temperature measuring head of the thermocouple is located at the other end of the screw plug. One end outside. The two ends of the screw plug 2 are sealed with an adhesive to seal the thermocouple.

[0023] The screw plug 2 is cylindrical. In the center of the screw plug, there is a thermocouple installation hole through longitudinally, which is used to place the thermocouple 1 . The screw plug is divided into a screw plug head section, a screw plug neck section and a screw plug rod section. The screw plug head section of the screw plug is located at one end of the screw plug, and is hexagonal out...

Embodiment 2

[0032] The difference between this embodiment and Example 1 is that the seal between the thermocouple 1 and the screw plug 2 is provided with a sealing device rubber sealing ring 4, and the sealing effect is better and more durable.

[0033] Such as Figure 5-7 shown. This embodiment includes a thermocouple 1 , a screw plug 2 and an adhesive 3 . Among them, the thermocouple 1 is installed in the thermocouple installation hole at the center of the screw plug 2, and the lead-out wire end of the thermocouple is located outside the end face of the screw plug, and the temperature measuring head of the thermocouple is located at the other end of the screw plug. One end outside. The two ends of the screw plug 2 are sealed with an adhesive to seal the thermocouple. Two or one sealing ring 4 is installed in the thermocouple mounting hole of the screw plug.

[0034] The screw plug 2 is cylindrical. In the center of the screw plug, there is a thermocouple installation hole through l...

Abstract

The invention relates to a device for measuring oil temperature of a steam cylinder base. The device is characterized in that a thermocouple is arranged into a thermocouple mounting hole which is formed in the center of a screw plug, the leading-out line end of the thermocouple is positioned at the exterior of one end surface of the screw plug, and a temperature measuring working head of the thermocouple is positioned at the exterior of the other end surface of the screw plug; the thermocouple is sealed by an adhesive at both ends of the screw plug. The device is characterized in that by using a thread block plug as an adapter, and using the adhesive as the connecting type, the thermocouple is fixedly arranged on the block plug, and a hydraulic joint of an air bleeding nozzle on the steam cylinder base of a brake device is used as a plugging point to measure the temperature in real time. The device has the characteristics that the property is stable, the convenience in use is realized, the maintenance is not needed, and the manufacturing cost is low; after multiple bench brake tests and experiments, the loosening and oil leakage are avoided, the temperature of the measured medium can be accurately and reliably measured and indicated, and the temperature measuring requirement of aviation wheel brake test is met; the high temperature, low temperature, high pressure and vibration can be borne, and the device is suitable for installation and testing conditions of temperature of -60 to 200 DEG C and hydraulic oil pressure of 28MPa.

Description

technical field [0001] The invention relates to temperature measurement of an aircraft wheel brake device, in particular to a device for measuring the oil temperature of a cylinder seat by using a thermocouple. Background technique [0002] During the braking process of the aviation wheel, the huge kinetic energy of the aircraft is converted into heat energy through the mechanical friction of the brake disc. The temperature rises. The cylinder block is a device that powers the wheel brakes and is equipped with multiple hydraulically actuated pistons. After braking, the heat generated by the brake disc is partially transmitted to the cylinder block, which increases the temperature of the cylinder block, and then increases the temperature of the hydraulic oil in the inner cavity of the cylinder block. In order to quantitatively monitor the temperature change of the cylinder seat oil during and after braking, it is necessary to use a temperature measuring device or instrument...
