In some exemplary embodiments, as shown in fig. 2-5, the conduit 300 monitored by the conduit fault monitoring system may be a steam conduit or the like. As shown in fig. 2, the pipe 300 may include an inner pipe 301, an outer pipe 302, and an insulation 303. As shown in fig. 2, the outer tube 302 may be sleeved on the outer side of the inner tube 301, and the insulation layer 303 may be located in an annular space formed by the inner tube 301 and the outer tube 302. The inner tube 301 can be insulated by the insulating layer 303, so that heat loss is avoided, vibration transmitted from the inner tube 301 to the outer tube 302 can be absorbed to a certain extent by the insulating layer 303, and damage to the detection device caused by vibration can be avoided. Illustratively, the material of the insulating layer 303 may be rock wool or the like. As shown in fig. 2-5, the detection device 100 may be mounted to an outer wall of the outer tube 302. In the embodiment of the present application, taking the pipe 300 as a steam pipe as an example, during the normal operation of the steam pipe, the steam flowing into the steam pipe causes the pipe 300 to vibrate, the vibration can be transmitted to the outer pipe 302 via the inner pipe 301 and the insulation layer 303, the vibration wave generated by the steam in the inner pipe 301 of the steam pipe and the vibration wave transmitted to the outer pipe 302 are corresponding, and the characteristics of the vibration wave are relatively stable, so that the detection device 100 is mounted on the outer wall of the outer pipe 302, the vibration wave of the pipe 300 can be detected, and by mounting the detection device 100 on the outer wall of the outer pipe 302, the dismounting convenience of the detection device can be improved, the mounting and maintenance convenience of the detection device can be improved, and the maintenance cost of the whole pipe fault monitoring system can be reduced.
In some exemplary embodiments, as shown in fig. 2, the detection device 100 may include a vibration sensor 101 and a mount 102. As shown in fig. 2, the mount 102 may be block-shaped, and, as an example, the mount 102 may be rectangular block-shaped or circular block-shaped, etc. Mount 102 may be mounted to outer tube 302 by bolting or welding, etc.
As shown in fig. 2, the mounting seat 102 may have a first surface 102-1 and a second surface 102-2 that are disposed opposite to each other, where the first surface 102-1 may contact the contour surface of the outer tube 302, and the first surface 102-1 may be an arc surface so as to contact and fit with the contour surface of the outer tube 302, so as to improve the stability of mounting the mounting seat 102. The second face 102-2 may be planar to provide stable support for the vibration sensor 101. The material of the mounting seat 102 may be metal or nonmetal. The mounting seat 102 may be formed by forging or injection molding.
In some exemplary embodiments, the detection device 100 may include a plurality of vibration sensors 101 and a plurality of mounts 102, and one vibration sensor 101 and one mount 102 may be disposed in a group and together form one detection unit. The plurality of detection units may be arranged at intervals along the length direction of the pipe 300, or the plurality of detection units may be arranged at intervals along the circumferential direction of the pipe 300, or the like.
In some exemplary embodiments, the vibration sensor 101 may include at least one of a fiber grating vibration sensor, a distributed fiber vibration sensor, and a mechanical vibration sensor. For example, the vibration sensor 101 may be a fiber grating vibration sensor, and when different faults occur in the steam pipeline, for example, the pipe wall of the pipeline is thinned, the pipe wall of the pipeline is cracked, the pipeline is water-shocked, and the fiber grating vibration sensor may detect different vibration waves of the steam pipeline. Under the action of vibration wave, the fiber bragg grating of the fiber bragg grating vibration sensor installed to the steam pipeline is strained, so that the effective refractive index and the grating pitch of the fiber bragg grating are changed differently, when the laser pulse light wave emitted by the light source in the fiber bragg grating vibration sensor passes through the grating, the reflected wave reflected back generates a certain degree of drift, the fault analysis device 200 can identify the change degree of the fault of the steam pipeline according to the data transmitted by the fiber bragg grating vibration sensor, and the fault analysis device 200 can realize the real-time monitoring of the fault of the steam pipeline through the identification of different fault vibration waves. By way of example, the vibration sensor 101 may be a mechanical vibration sensor, the mechanical vibration sensor may monitor low-frequency and high-frequency vibrations, the fault analysis device 200 may output analog electrical signals through data collected by the mechanical vibration sensor, convert the analog electrical signals into digital signals through a data collector, and send the digital signals to a display component such as a computer, where the fault analysis device 200 may display a vibration curve on the display component through processing the digital signals, so as to implement graphical representation of vibration waves, and facilitate fault identification.
In some exemplary embodiments, the fault analysis apparatus 200 may determine the fault type of the pipe 300 according to the vibration wave transmitted from the detection apparatus 100, and the fault type may include at least one of pipe creep, pipe thermal deformation, insulation failure, pipe corrosion, pipe crack, pipe leakage, condensate water accumulation, water hammer, and pipe burst. For example, during operation of the steam pipe, high-temperature and high-pressure steam rapidly flows from the inner pipe 301, so that the inner pipe 301 generates vibration, and the vibration sensor 101 can monitor the vibration. If the steam pipe is subject to creep, the vibration wave transmitted to the vibration sensor 101 is different from the vibration wave transmitted to the vibration sensor 101 by the steam pipe which is not subject to creep. The fault analysis device 200 can store the vibration wave corresponding to the pipe creep of the pipe 300 through monitoring and analyzing the obtained vibration wave, and can monitor whether the pipe has creep fault in real time. For example, during operation of the steam pipe, high-temperature and high-pressure steam rapidly flows from the inner pipe 301, so that the inner pipe 301 generates vibration, and the vibration sensor 101 can monitor the vibration. If the insulation 303 of the steam pipe fails, the vibration wave transmitted to the vibration sensor 101 is different from the vibration wave transmitted to the vibration sensor 101 by the steam pipe in which no insulation failure occurs. The fault analysis device 200 can store the vibration wave corresponding to the failure of the insulation layer of the pipeline 300 through monitoring and analyzing the obtained vibration wave, and can monitor whether the failure of the insulation layer occurs in real time.
For example, during operation of the steam pipe, high-temperature and high-pressure steam rapidly flows from the inner pipe 301, so that the inner pipe 301 generates vibration, and the vibration sensor 101 can monitor the vibration. If the steam pipe corrodes, the vibration wave transmitted to the vibration sensor 101 is different from the vibration wave transmitted to the vibration sensor 101 by the steam pipe that does not corrode. The fault analysis device 200 can store the vibration wave corresponding to the pipe corrosion of the pipe 300 through monitoring and analyzing the obtained vibration wave, and can monitor whether the pipe has corrosion fault in real time.
For example, during operation of the steam pipe, high-temperature and high-pressure steam rapidly flows from the inner pipe 301, so that the inner pipe 301 generates vibration, and the vibration sensor 101 can monitor the vibration. If a water hammer occurs at a certain position in the steam pipeline, the water hammer can generate huge impact vibration and loud sound. Water hammer is a phenomenon that the pressure greatly fluctuates due to the rapid change of the flow rate of liquid in a pressurized pipeline. If the steam pipe is water-shocked, the vibration wave transmitted to the vibration sensor 101 is different from the vibration wave transmitted to the vibration sensor 101 by the steam pipe in which the water-shocked is not generated. The fault analysis device 200 can store the vibration wave corresponding to the water hammer of the pipeline 300 through monitoring and analyzing the obtained vibration wave, and can monitor whether the water hammer fault occurs in the pipeline in real time.
In some exemplary embodiments, the pipeline fault monitoring system may further include an alarm device, the alarm device may be electrically connected to the fault analysis device 200, and the fault analysis device 200 may be further configured to control the alarm device to issue an alarm alert when the vibration wave is determined to coincide with the preset waveform, so as to perform safety precaution, and may improve the safety of production. By way of example, the alert reminder may be a sound or a flashing light, etc. By way of example, the preset waveform may include a waveform corresponding to at least one of pipe creep, pipe heat deformation, insulation failure, pipe corrosion, pipe cracking, pipe leakage, condensate accumulation, water hammer, and pipe bursting. For example, when the fault analysis device 200 determines that the vibration wave matches a preset waveform corresponding to the pipe creep, it may determine that the pipe creep fault occurs in the pipe.
In some exemplary embodiments, the pipe fault monitoring system may further include a drain valve mounted to the pipe 300, and the drain valve may be mounted to the inner pipe 301. In the working process of the steam pipeline, if condensate water accumulation faults occur, the drain valve can be opened, condensate water is timely discharged from the pipeline, the possibility of water attack caused by condensate water accumulation can be avoided, and the probability of pipe explosion can be reduced.
In some exemplary embodiments, a drain valve may be electrically connected to the fault analysis apparatus 200, and when the fault analysis apparatus 200 determines that the pipe 300 has a condensate accumulation fault, the drain valve may be controlled to be opened to drain condensate from the pipe in time, thereby shortening a period of condensate drain and improving a response speed of the system.
The embodiment of the application provides a pipeline fault identification method which is applied to the pipeline fault monitoring system in any embodiment. The pipeline fault identification method comprises the following steps:
the vibration wave of the pipe is detected by the detection device, and the detected vibration wave is transmitted to the failure analysis device.
The fault analysis device judges the fault type of the pipeline according to the obtained vibration wave.
In some exemplary embodiments, the pipe fault identification method further comprises: the fault analysis device compares the vibration wave received from the detection device with a preset waveform to judge the fault type of the fault of the pipeline.
