Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of leak detection system being applied to low-pressure coal saver, comprises low-pressure coal saver 1, first pressure transducer 5, first flow sensor 4, second pressure transducer 7, second quantity sensor 6, PLC 8, host computer 9, cloud computing 10.Described first pressure transducer 5 and first flow sensor 4 are arranged on the inlet channel of low-pressure coal saver 1, and the first pressure transducer 5 and first flow sensor 4 signal are connected to PLC; Described second pressure transducer 7 and second quantity sensor 6 are arranged on the outlet conduit of low-pressure coal saver 1, and the second pressure transducer 7 signal is connected to PLC 8; Described PLC 8 gathers the data of the first pressure transducer 5, first flow sensor 4, second pressure transducer 7 and second quantity sensor 6, and by host computer 9 Signal transmissions to cloud computing 10.
Be applied to a process of leaking hunting for low-pressure coal saver, concrete steps are as follows:
(1) obtained pressure and the flow of low-pressure coal saver inlet channel internal water by the first pressure transducer and first flow sensor measurement, and conveying is stored to PLC;
(2) obtained the pressure of low-pressure coal saver outlet conduit internal water by the second pressure transducer measurement, and conveying is stored to PLC;
(3) after PLC collects the data of the first pressure transducer, first flow sensor and the second pressure transducer, by host computer Signal transmissions to cloud computing, normal pressure difference when described cloud computing storage inside has that low-pressure coal saver normally works under different flow and loading condition; After cloud computing receives data, calculate the pressure difference value that the first pressure transducer and the second pressure transducer record, and the normal pressure difference corresponding to the flow value load instantly of obtained pressure difference value and cloud computing storage inside and first flow sensor recorded compares, if the difference overpressure difference fluctuation range between the pressure difference value obtained and normal pressure difference (normal pressure difference ± 5%), then judge that low-pressure coal saver leaks.
