Description
Technical field
The utility model relates to a kind of monitoring system, relates in particular to a kind of air compressor axial translation monitoring system.
Background technology
Technology for Modern Equipment maximization day by day, high speed, the air compressor that particularly is widely used in the industries such as coal, electric power, metallurgy, petrochemical industry closely are connected with production run, formed large system, in national industrial development, there is great effect people's productive life and national economic development aspect.Yet, in actual motion, various faults occur in air compressor often, jeopardize staff's life and health and the normal productive life of the people, once this type systematic breaks down, may cause major accident, and cause heavy losses.Be widely used in mine, the every field air compressor such as metallurgy, chemical industry, oil, the construction of road and bridge large problem that is in operation is the emergency brake caused because axial translation is excessive.
The large problem that air compressor is in operation causes and stops in emergency because axial translation is excessive.To the state-owned air compressor of part over nearly 30 years, because axial translation exceeds standard, cause the field data statistics of fault to carry out theoretical analysis, cause the reason of fault that 3 aspects are arranged:
1, axial translation measurement mechanism precision is not high, causes system not stop when axial translation is transfinited;
2, the fault of machine itself is mainly that axial thrust is excessive to be caused, and due to design reasons, the residual axial force that makes machine produce in operation process surpasses design load, and makes repeatedly scram of machine;
3, the fault of lubricating system, enter the factors such as the lubricants capacity deficiency of thrust bearing and lubricating oil matter is bad.
Summary of the invention
The purpose of this utility model provides a kind of air compressor axial translation monitoring system with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises photoelectric commutator, amplifying circuit, single-chip microcomputer, light-operated circuit, alarm, LCD display and keyboard, described photoelectric commutator is arranged on the rotating shaft side of described air compressor, the signal output part of described photoelectric commutator is connected with the signal input part of described amplifying circuit, the signal output part of described amplifying circuit is connected with the monitor signal input end of described single-chip microcomputer, the optically-controlled signal end of described single-chip microcomputer is connected with the signal end of described light-operated circuit, the alarm signal output ends of described single-chip microcomputer is connected with the signal input part of described alarm, the display output terminal of described single-chip microcomputer is connected with the signal input part of described LCD display, the signal output part of described keyboard is connected with the signal input part of described single-chip microcomputer.
The beneficial effects of the utility model are:
The utility model utilizes the automatic control of high speed AVR to the laser incident intensity, shine at a certain distance the measured object surface after receiving by incident optical, after the modulation of intensity compensation reflective optical fiber displacement sensor, convert electric signal to by photoelectric switching circuit, then carry out the A/D conversion by AVR.Analyze data, obtain the axial translation under the different light intensity irradiation, average and obtain high-precision measured value.The utlity model has advantage simple in structure, that conversion accuracy is high and integrated level is high.
The accompanying drawing explanation
Fig. 1 is the structured flowchart of air compressor axial translation monitoring system described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises photoelectric commutator, amplifying circuit, single-chip microcomputer, light-operated circuit, alarm, LCD display and keyboard, described photoelectric commutator is arranged on the rotating shaft side of described air compressor, the signal output part of described photoelectric commutator is connected with the signal input part of described amplifying circuit, the signal output part of described amplifying circuit is connected with the monitor signal input end of described single-chip microcomputer, the optically-controlled signal end of described single-chip microcomputer is connected with the signal end of described light-operated circuit, the alarm signal output ends of described single-chip microcomputer is connected with the signal input part of described alarm, the display output terminal of described single-chip microcomputer is connected with the signal input part of described LCD display, the signal output part of described keyboard is connected with the signal input part of described single-chip microcomputer.
The utility model shows through initialization, pulse generation, disconnected data acquisition, auditory tone cues, data analysis, the result of signal.Press start key, system produces pulse at the air compressor sensor, and each pulse changes light intensity by photoelectric commutator; The AVR light-operated circuit is changed by photosignal, constantly detects the axle position, and when the complete laggard row storage of conversion and measurement, the air compressor sensor sends pulse simultaneously, after time delay a period of time, again signal is changed.Two light paths are sampled respectively after 5 times, stop sampling.The analytical sampling data, if the represented axial translation of measured value is greater than margin of safety, the audible alarm prompting is presented at measurement result on LCD display simultaneously.
