Description
Technical field
The utility model relates to measure of axle-temperature technical field, is specifically related to a kind of measure of axle-temperature thermal resistance bar fixed connection apparatus of anti-vibration.
Background technology
The measurement of axle temperature is the important measuring point of large-scale rotation blower fan monitoring and protecting, in order to protect Fan Equipment, once find that the too high necessary Concatenate shut-down of its axle temperature is with proterctive equipment during fan operation.And after fan parking, coal gas, dust etc. that molten steel blowing produces can not be pumped, pneumatic steelmaking is then interlocked and is mentioned oxygen rifle, and blowing is interrupted.
In steel-making actual production process; usual employing is based on the axle temperature of the temperature measuring equipment measurement blower fan of thermal resistance; thermal resistance bar is threaded connection fixing by fixed connection apparatus and fan shaft pedestal over cap; thermal resistance bar inserts in the lubricating cooling oil of fan shaft through the perforate of over cap, by measuring the temperature of lubricating oil to reflect the axle temperature of blower fan.Temperature measuring equipment based on thermal resistance bar is inevitably subject to the impact of blower fan whirling vibration; the production that axle temperature protection is caused is interrupted usually not because blower fan axle temperature is too high; but cause abnormal signal because thermometric thermal resistance bar breaks down in the environment of vibration; final shutdown stops production, and overhauls temperature measuring equipment.And the coal gas containing high concentration in the flue gas that dedusting fan extracts, the accident caused for preventing gas leak, scene has all installed seal closure additional for dedusting fan, must first remove blower fan seal closure before process temperature measuring equipment fault.Therefore, the equipment failure of fan shaft temperature measurement not only can bring greater loss to production, and the expense of its dismounting and change maintenance is simultaneously also relatively high.
At present, in order to reduce the impact vibrated, mainly following measures is taked to the Thermistor Temperature Measurement equipment being used in this type of vibration environment: 1, resistor core takes silica gel packaging in protective casing; 2, the protective casing of resistor core outside is also that thermal resistance bar is run business into particular one, and allows it have certain elasticity; 3, small spring is installed additional with antivibration between binding post clamping nut and connector lug.Above measure plays a role for vibrationproof, but has its unilateral limitation, system comprehensively can not eliminate and vibrate the impact that brings, equipment failure still can occur in actual production and send spurious signal and mistakenly stop machine.
Due to spurious signal, the reason of mistakenly stop machine mainly contains following two kinds: 1, Signal transmissions binding post and thermal resistance bar are one overall, in the process of thermal resistance bar with blower fan whirling vibration, and the easy loose or dislocation of connector lug and cause axle temperature spurious signal; 2, thermal resistance bar is provided with elasticity after running business into particular one, but easy flexural deformation even fractures in it is with casing vibration processes.Resistance is different and reflect actual temperature value at different temperatures by its resistor core for thermometric thermal resistance bar; no matter be himself fracture or connector lug loose or dislocation; the resistance delivering to measuring system is all infinitely great; the temperature calculated also is infinity; system can judge that blower fan axle temperature is too high and send stopping signal; cause stopping production, and some are difficult to the situation of structure or the complex manufacturing of removing, this type of mistakenly stop product can cause huge economic loss.Therefore, be necessary to improve prior art.
