Description
Technical field
The utility model relates to a kind of diaphragm pump failure warning system based on vibration detection.
Background technique
Pipeline carry be that both railway transports, highway transport, extra large land transportation are defeated, the fifth-largest means of transportation after air transportation, pipeline carry not only zero pollute, low energy consumption, and be that ecotope is not almost destroyed.For some road traffic inconveniences, the transportation that material is easily shed or easily leaked, embodied the advantage that pipeline is carried especially.So in recent years, pipeline conveying industries development is very rapid, but how to guarantee the safety of conveying of pipeline and stable, is a urgent problem.
Diaphragm pump is one of nucleus equipment of pipeline conveying, and it is the power take-off that pipeline is carried, so the safety problem of the diaphragm pump core security problem that namely pipeline is carried.Only has effective operation of diaphragm pump, the normal operation that the guarantee pipeline is carried.Therefore carry out the diagnosing malfunction to diaphragm pump by vibration detection, very necessary for the quality of evaluation diaphragm pump operation conditions.
Due to pipeline, carrying is an emerging means of transportation, less for the research of pipeline delivery safety problem, even blank.At present, for the mode of the fault diagnosis of diaphragm pump, be mainly the knowhow by the workman, and detection mode is generally oil quality analysis and temperature detection.Oil quality analysis need to be dismantled equipment, works powerful larger; Temperature detection is subject to the impact of environment temperature environment.
The model utility content
The utility model provides a kind of diaphragm pump failure warning system based on vibration detection, and the oscillating signal of take while breaking down to be produced is foundation, through the processing of computer, send in time warning, to fix a breakdown, guarantee that industrial safety normally moves, simple in structure, easy to operate.
The utility model has adopted following scheme: a kind of diaphragm pump failure warning system based on vibration detection comprises acceleration transducer 1, amplification circuit 2, A/D converter 3, computer 4, alarm module 5; Acceleration transducer 1 is fixed on diaphragm pump, and the output terminal of acceleration transducer 1 is connected with A/D converter 3 by amplification circuit 2, and the output terminal of A/D converter 3 connects computer 4, and computer 4 is connected with alarm module 5.
Acceleration transducer 1 is three, be arranged on respectively diaphragm pump axially, radially and Vertical direction.
Alarm module 5 can be selected warning light or buzzer.
The beneficial effects of the utility model: the oscillating signal produced when the utility model breaks down is foundation, through the processing of computer, sends in time warning, to fix a breakdown, guarantees that industrial safety normally moves, simple in structure, easy to operate.
The accompanying drawing explanation
Fig. 1 is basic framework figure of the present utility model;
Fig. 2 is fault diagnosis of the present utility model and alarm flow figure;
In figure: 1-acceleration transducer, 2-amplification circuit, 3-A/D transducer, 4-computer, 5-alarm module.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1: a kind of diaphragm pump failure warning system based on vibration detection comprises acceleration transducer 1, amplification circuit 2, A/D converter 3, computer 4, alarm module 5; Acceleration transducer 1 is fixed on diaphragm pump, and the output terminal of acceleration transducer 1 is connected with A/D converter 3 by amplification circuit 2, and the output terminal of A/D converter 3 connects computer 4, and computer 4 is connected with alarm module 5.
Alarm module 5 can be selected warning light or buzzer.
Working principle of the present utility model: acceleration transducer 1 carries out signals collecting, vibrational state by 1 pair of diaphragm pump in service of acceleration transducer is detected, obtain effective oscillating signal, state to machinery in service carries out correct detection, obtain rational oscillating signal, the analogue signal that amplification circuit 2 degree of will speed up sensors are collected is amplified, and is converted into digital signal through A/D converter 3, computer 4 is built-in with signal processing module, state recognition module and historical data base; Gather the oscillating signal of diaphragm pump by signal acquisition module, signal processing module in computer 4 carries out pretreatment and the analysis of numerical value to gathered vibration data again, denoising after filtering, useful fault message is extracted from a large amount of background noises with disturbing, and then state recognition module is mated oscillating signal and is identified according to the data in historical data base; Historical data base, by collection and analysis to the historical signal data, according to the characteristic (numbering of motor and diaphragm pump, diaphragm pump flow, monitoring result evaluation etc.) of different type of machines, is set corresponding effectively threshold value; Finally, if oscillating signal is abnormal, show relevant fault vibration frequency spectrum on computer 4, start alarm module 5 simultaneously, send warning message, the staff according to physical device runnability to diagnosing malfunction and eliminating.
In order to obtain comprehensive signal, acceleration transducer 1 is three, be arranged on respectively diaphragm pump axially, radially and Vertical direction.
The utility model describes by accompanying drawing, in the situation that do not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
