Description
Technical field
The utility model relates to the temperature field test technology.
Background technology
Chamber temperature field measurement thermopair is the main survey instrument that is used for checking the temperature field functional reliability, because the measuring section structure is very complicated, adopted gas, water dual-cooled mode, also comprise complicated rotation and gear train, make the installation difficulty of detector probe thermopair bigger, need be with the big decomposition of measuring section, progressively remove the outer cone section, the inner cone section, motor drive mechanism, gear train, after compressing parts such as stop means, after whirligig moved forward to correct position along horizontal axis, back out screw, open the cover plate of whirligig front end, pull up the contact pin of thermopair, could extract thermopair out from compensating wire.Generally speaking, 4 thermopairs are installed on the whirligig.The order that thermopair is installed is just in time opposite, the mounting or dismounting working time is longer, each approximately 3 hours times spent, make the workload of changing thermopair in the test heavy, and per hour 10,000 kilowatts of power consumptions in the process of the test, cause very big energy dissipation, in the period of test mission anxiety, even the scheduling of influence test.
Summary of the invention
The purpose of this utility model is to provide a kind of chamber temperature field test device of being convenient to install thermopair.
The utility model provides a kind of new combustion chamber temperature field test device, by outer sleeve 1, outer cone section 2, inner sleeve 3 and inner cone section 4 constitute blast tube, thermopair 5 is settled in the blast tube porch, inner sleeve is equipped with whirligig 14 for 3 li, thermopair 5 is inserted in 14 li of whirligigs, be screwed, and be connected with compensating wire with contact pin at the axle center part of whirligig 14, whirligig 14 is driven through gear train 7 by the motor drive mechanism 6 that is contained on the outer sleeve 1, gear train 7 passes measurement, cooling, transmission cavity 8, lever position indicator 9 and angular transducer 10 are equipped with in gear train 7 outer ends, gear train 7 inner ends are equipped with and are compressed stop means 11, outer sleeve 1, outer cone section 2, inner sleeve 3, inner cone section 4 and whirligig 14 all are provided with cooling water channel, inner sleeve 3 and inner cone section are connected with cold gas for 4 li, outer sleeve 1 front end has joint flange, it is characterized in that: the standpipe of described whirligig 14 front portions partly is provided with arc-shaped partition 15 and cover plate 16, arc-shaped partition 15 forms the cold gas cavity that detector probe is installed with cover plate 16, is the chilled water cavity outside the arc-shaped partition 15.During work, the thermopower that thermopair records is exported by transfer wire through compensating wire.Change at needs under the situation of thermopair 5 and back out screw, open cover plate 16, open the closing disk 13 of whirligig 14 front ends, pull up the contact pin of thermopair, just can take out thermopair 5, and not need measuring section is decomposed greatly from compensating wire.
The new combustion chamber temperature field test device that the utility model provides, its arc-shaped partition 15 can be circular with the cold gas cavity that cover plate 16 forms, air-flow is unobstructed.
The new combustion chamber temperature field test device that the utility model provides, its advantage is: be convenient to dismounting, the dismounting time of thermopair 5 is reduced to 1 hour from original 3 hours, saved a large amount of energy (per hour power saving is 10,000 kilowatts), alleviated tradesman's labour intensity.
