Abstract

The invention belongs to the technical field of the energy power industry, and particularly relates to a vibration sensing system with a cooling shell. According to the invention, an air-cooled slotted lug and a process gas nozzle for diffusing a flow field of cooling gas are adopted, a cooling gas channel with a special structure and a strand of cooling gas pipe are additionally arranged betweenthe sensor base and the high-temperature casing bracket, and the cooling gas pipe directly jets to the sensor base and flows out along the channel, so that convection cooling is carried out on the whole semi-open chamber; and a cooling air nozzle is arranged on the side surface of the sensor to cool the sensor again. Multiple cooling modes are adopted in parallel to improve the cooling effect, andpractical application verifies that the surface temperature of the sensor can be greatly reduced, and the problem that the measurement precision of the sensor is affected due to too high temperatureis effectively avoided.

Description

technical field

[0001] The invention belongs to the technical field of energy and power industry, and in particular relates to a vibration sensing system with a cooling shell. Background technique

[0002] While the industrial gas turbine rotates at high speed, it is often accompanied by vibration. In order to comprehensively monitor the operation of the unit, it is necessary to arrange vibration sensors outside the casing of the unit for measurement. The gas turbine combustor and the area of ​​the outer casing of the rear turbine belong to the high-temperature area, and the temperature on the surface of the casing reaches above 600°C. However, the cooling effect of the traditional sensor bracket is not good due to design structural defects, which often leads to vibration sensors in this area due to overheating. Warm and ineffective.

[0003] In the West-to-East Gas Pipeline Project, the supercharger units using traditional vibration sensor brackets in Xinjiang Yandun Stati...
