The beneficial effects of the utility model are:
This utility model use a kind of can the omnidistance system of real-time remote monitoring boiler significant points swell increment.This system
It is made up of displacement transducer, data acquisition unit, computer three part.With displacement transducer, by the three-dimensional expansion of boiler component
Displacement is converted into the signal of telecommunication, after data acquisition system, is input in computer, processes through computational analysis, with
The form of 3-D graphic shows on the display of master control room, clear and intuitive, facilitates operations staff to understand boiler plant in real time
Expansion status.Alleviate the working strength of operations staff, reduce danger, improve the operation level of unit.
In this utility model, displacement refers to that certain surface of object or certain point are relative to reference surface or reference point locations
Change, displacement divides again displacement of the lines and angular displacement two kinds, and these are all the metering systems in a dimension, and power plant boiler
Expansion point is measured as three-dimensional transfer point, and three-dimensional to be realized will use the measurement apparatus in 3 directions, and the size of measuring instrument and
Measurement scope is the most all restricted, being actually needed of site of deployment to be met, and through research and actual argument, chooses a kind of actual
Measurement scope is the inductive displacement transducer of 10-70CM.Inductive displacement transducer be a kind of belong to metal sensing linear
Device, after switching on power, will produce an alternating magnetic field in sensitive surface, when metal object is close to this sensitive surface, in metal then
Produce eddy current and drawn the energy of agitator, make agitator output amplitude linear attenuation, then come according to the change of attenuation
Complete the purpose of Poul Dorset Sheep object.Owing to boiler expansion point is more, data acquisition unit to be used is to all expansion point positions
Displacement sensor carries out in data set, is transferred to computer by RS485 communications protocol mode, and computer is through data analysis and figure
Shapeization processes, and ultimately forms 3-D view.
This utility model can solve an on-the-spot actual techniques difficult problem conscientiously, and figure and curve by measurement variation are true
Reflection boiler expansion direction, thoroughly make boiler expansion measure can become four main tubes of boiler monitoring an important step and judgement depend on
According to, play its important function;The weld bond cracking caused prevention superheater tube screen because expanding reason has certain basis for estimation, energy
Enough formulate unit scheduled overhaul time and maintenance position ahead of time, it is to avoid because weld bond ftractures the unit unplanned outage event caused
Occur, enable unit to run reliably and with long-term, improve the economical of unit;Use data acquisition module, save electricity in a large number
Cable, saves Master Cost and construction labour cost accordingly;Reduce equipment loss and maintenance cost, it is to avoid manual site note
Record data.
