The pipeline leakage monitoring system is based on negative-pressure wave effect, and realizes leakage detection and positioning by the aid of transient pressure variation of a pipeline, the sensing component senses pressure variation data of the pipeline and transmits the pressure variation data to the processing component, the processing component computes and analyzes the received pressure variation data and transmits results to the display to display the results, and accordingly the pipeline leakage monitoring system can uninterruptedly monitor the pressure inside the pipeline round the clock.
Description
Technical field
The utility model design line transportation field, especially a kind of pipeline leakage monitoring system.
Background technique
Oil transmission line is the lifeline of oilfield enterprise, is cohesion personnel's the wisdom and the crystallization of sweat.Because the lawless person plants the caused pipeline perforation of corrosion in valve and the pipeline running, causes a series of serious problems such as national wealth runs off, oil field ordinary production order is suffered to destroy, environment is polluted.Traditional in the past oil transmission line management shows managerial deficiency gradually in the mode of artificial line walking, first and last station measurement shoutage comparison monitoring pipeline leakage.The lawless person can plant the valve process and face the pipeline that corrosion failure might take place at any time with interior finishing at 1.5 hours in the production process, find that by the measurement shoutage comparison a large amount of leakages still need a period of time, as organize line walking to determine leak source, The dear one is gone and the chamber remains deserted already for the lawless person, and may leak substantial oil and cause tremendous economic loss.
Western developed countries such as the U.S. all pipelines of law-making stipulation leak detection system must be installed.Therefore, leakage monitoring not only becomes the important process content of present oil transport pipeline production safety management, also will be the indispensable guarantee of the normal operation of pipeline from now on.Realize the leakage monitoring of oil transport pipeline, have great importance for the generation of timely discovery leakage failure, the safe operation of guaranteeing oil transportation production and pipeline, minimizing stolen case, the modern management level of raising long distance pipeline etc.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, a kind of pipeline leakage monitoring system, comprise inductive component 1, processing components 2 and display device 3, processing components is connected with display device with inductive component respectively, is demonstrated by display device after the variation in pressure during inductive component in the monitoring pipeline transfers to the processing components analysing and processing with pressure data.Inductive component comprises induction installation 4, data acquisition unit 5 and data trasmission package 6, and data acquisition unit is connected with data trasmission package with induction installation respectively.Be sent to processing components by data trasmission package after the data capture that data acquisition unit is sensed induction installation.Processing components comprises processor 9 and storage device 10, and processor calculates the data of receiving, and result transmission to display device is demonstrated, storage device then with the data storage received so that call later on and check.
With reference to Fig. 2, the utility model induction installation adopts high quick pressure transmitter 7, can also install 8 pairs of pressure of flow transducer and flow additional and monitor simultaneously.When using this product, a plurality of inductive components are installed on the pipeline 11 that will monitor one by one with the spacing less than 80 kilometers, every two adjacent inductive components are connected with a processing components, and each processing components connects a display device.When pipeline takes place to leak, owing to the inside and outside pressure reduction of pipeline, make the abrupt pressure reduction of leakage place, leak liquid on every side is because the existence of pressure reduction replenishes to leak, and the unexpected negative pressure that forms fluctuates in pipeline.This suction wave, and with index percent decay, smooths down to upper and lower section propagation of pipeline gradually from leakage point, and this makes pressure surge absolutely different with the situation of normal pressure fluctuation, the forward position with steeper.The inductive component that is installed in the two ends, leak point receives this ripple signal and it is transferred to processing components.Processing components will be in conjunction with the variation characteristic of pressure, judge the situation of leakage, the time difference of the instantaneous pressure ripple arrival upper and lower end that produces when leaking by measuring and manifold pressure velocity of wave propagation calculate the position of leakage point and transfer to display device and show, and can also call daily Monitoring Data in case of necessity and compare from storage device.
The mode of execution of the above is a preferred case study on implementation of the present utility model; be not to limit practical range of the present utility model with this; so the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be encompassed in the protection domain of the present utility model.
