Problems solved by technology

[0009] 3. Stress corrosion: Stress corrosion causes the bellows to be damaged layer by layer, eventually leading to leakage
[0010] 4. Over-compensation: The thermal displacement of the heating pipe exceeds the design value of the compensator, which causes a decrease in fatigue life, eventually leading to a decrease in service life and damage

Abstract

The invention relates to a monitoring and early warning device for a metal bellow compensator and a monitoring method of the monitoring and early warning device and belongs to the technical field of intelligent monitoring. The monitoring and early warning device comprises a pressure sensor, a temperature sensor, an axial displacement sensor, a bracket I, a bracket II, a radial displacement sensor,an analog quantity collection module, a solar panel, a storage battery, a wireless router, a data processing center, a user monitoring center, a connecting pipe I, a leakage alarm sensor, a bellows,a stress-strain sensor, a connecting pipe II, a camera and a wire, and the monitoring and early warning device is powered by a solar battery after the power is stored by the storage battery, or is powered by a power supply. According to the monitoring and early warning device, the compensator can be monitored comprehensively, whether the compensator is required to be changed or whether the compensator can be maintained to the overhaul period can be pre-judged, the problem of sudden damage of the compensator during pipe network running is solved, sudden shutdown of a pipe network due to damageof the compensator is prevented, and loss caused by shutdown is reduced; besides, the monitoring and early warning device is convenient to mount and energy-saving.

Description

technical field [0001] The invention relates to a monitoring and early warning device for a metal corrugated compensator and a monitoring method thereof, belonging to the technical field of intelligent monitoring. Background technique [0002] Pipes can be said to be necessary facilities in life, especially heating pipes, which are essential in winter in the north. The working medium in the heating pipeline is mainly water and water vapor, but the working medium in the pipeline and the environment in which the pipeline is located will have temperature changes. Variety. If the pipe cannot expand or contract completely freely when the temperature changes, thermal stress will be generated in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. [0003] The compensator is also called the expansion joint, the expansion joint or the expansion joint. It is a common part on the heatin...
