The best manufacturer of DTS distributed temperature sensing fiber optic detector pipeline leakage detection system-INNO

DTS temperatuurdetector pijpleidinglekdetectiesysteem

Transmissie via pijpleidingen heeft veel voordelen, zoals zuinigheid, efficiëntie, veiligheid, en stabiliteit, en wordt toegepast bij het transport van vloeistoffen zoals olie, aardgas, en water. Met de voortdurende vooruitgang van de sociale economie en technologie, Het leggen van pijpleidingen wordt op grote schaal toegepast. Pijpleidingsystemen worden veel gebruikt in industriële velden zoals aardolie, metallurgie, stedelijke watervoorziening, en aardgas. De kwestie van de bescherming van pijpleidingen wordt ook steeds prominenter in het bijzijn van mensen. Pijpleidingen liggen het hele jaar door ondergronds en zijn gevoelig voor corrosie, schade door vermoeidheid, of lekkage, wat niet alleen aanzienlijke economische verliezen veroorzaakt, maar ook het milieu vervuilt. Daarom, Het bestuderen van effectieve pijpleidinglekdetectietechnieken is van groot belang voor het veilig transporteren van pijpleidingen.

Measuring the temperature around the pipeline to determine whether a leak has occurred is currently a commonly used method. Echter, traditional temperature measurement is a single point measurement method, and monitoring the condition of a pipeline requires the deployment of a large number of temperature sensors, which brings difficulties to construction and maintenance. The fiber optic distributed temperature measurement system is a sensing system developed in recent years for real-time measurement of spatial temperature distribution. Fiber optic is both a transmission medium and a sensing medium, and the temperature effect of backward Raman scattering can be used to measure the temperature of the fiber in real-time; The use of optical time-domain reflection technology can accurately locate measurement points. This system can measure the temperature field distribution over long distances in a short period of time. Due to the small volume of the optical fiber, the measurement process will not affect the distribution of the original temperature field. Op hetzelfde moment, it also has the characteristics of flame prevention, explosie preventie, Corrosie bestendigheid, en weerstand tegen elektromagnetische interferentie. Daarom, the optical fiber distributed temperature measurement system has good application prospects in the field of pipeline leakage monitoring technology.

De fiber optic distributed temperature measurement system based on Raman scattering technology is currently widely used as a pipeline leakage monitoring system, which can measure long-distance pipeline routes. With the development of Gedistribueerde glasvezel temperatuur meting (DTS) technology in the petroleum industry, DTS has been able to achieve the following in the petroleum industry: measuring temperature profiles, identifying production fluids, determining the position of liquid and gas outlet, monitoring the working status of gas lift valves, and judging the judgment
Multiple applications such as crack location. Het belangrijkste principe van de DTS-technologie is het gebruik van het reflectieprincipe van optische vezels en de temperatuurgevoeligheid van omgekeerde Romeinse verstrooiing van optische vezels, vertrouwend op de kwantitatieve relatie tussen de voortplanting van licht in de optische vezel en de temperatuurveranderingen rond het optische vezelmedium om de temperatuur op de locatie van het optische vezelmedium te bepalen. Vanwege de kenmerken van anti-elektromagnetische interferentie, Corrosie bestendigheid, Hoge nauwkeurigheid, realtime monitoring van de temperatuur, stabiel signaal, en lage kosten, DTS technology is suitable for underground temperature profile monitoring in the petroleum industry.

DTS temperature measurement system

With the rapid development of fiber optic technology, the application of DTS temperature measurement system in the field of fire alarm has become increasingly mature. It is based on fiber optic Raman scattering technology, combined with advanced technologies such as high-frequency pulse laser, Optische golflengteverdeling multiplexing, Optische tijddomein reflectie, Acquisitie van hoogfrequente signalen, en zwakke signaalverwerking. It is mainly used in the chemical industry for cable tray and cable temperature measurement, storage tank temperature measurement, cable tunnel temperature measurement, coal conveyor belt temperature measurement, enzovoort. Although it has been applied to coal bunker ground temperature measurement, it has not been perfectly achieved due to various factors. The problems encountered in traditional coal bunker ground temperature measurement design are mainly construction difficulties, incomplete detection coverage areas, and extremely difficult maintenance and operation in the later stage.

DTS temperature measurement systems generally have types such as 1, 2, 4, en 8 Kanalen, with a measurement distance of 2km/4km/10km, enz. The most suitable model is selected based on the size of the detection area and the distance to the host. If the distance between the terminal in the tested area and the host exceeds the measurement distance, it can be divided into two channels; The positioning accuracy of the DTS temperature measurement system can reach 1m, and the length of each detection zone can be defined based on the size of the detected coal bin. Eindelijk, the real-time temperature of each zone will be displayed on the DTS host. Once the preset temperature value is exceeded, the host will alarm, prompt staff to conduct on-site inspection and confirmation, and take corresponding measures to curb the occurrence of fires.
