Description
Technical field
The utility model relates to tooling fields, and in particular to a kind of for survey aircraft air-conditioning device air quantity and wind pressure
Tooling.
Background technique
Currently, the air quantity of survey aircraft air-conditioning device and the mode of wind pressure have wind tunnel type and anemobiagraph two ways, but
Since aircraft air condition device air quantity is small, overbottom pressure is high, overbottom pressure may be up to 55kPa, have exceeded the measurement range of wind1 tunnel laboratory, and manage
There are inhomogeneities for air-flow in road, so that larger using the accuracy difference of anemobiagraph measurement air quantity, wind pressure.
The utility model provides a kind of survey aircraft air condition device air quantity, wind pressure tooling, can solve problem above.
Summary of the invention
The problem of being proposed according to background technique, the utility model provide it is a kind of for survey aircraft air-conditioning device air quantity and
The tooling of wind pressure is solved, and is next done to the utility model and is further illustrated.
A kind of tooling for survey aircraft air-conditioning device air quantity and wind pressure, the outlet air applied to aircraft air condition device
Mouthful, including vortex-shedding meter, pressure gauge, thermometer, pressure-regulating device, the first pipeline section and the second pipeline section, the flux of vortex street
The front end of meter is arranged on the air outlet of aircraft air condition device by the connection of the first pipeline section, the rear end connection second of vortex-shedding meter
Pipeline section sets gradually pressure gauge, thermometer and pressure-regulating device on the direction far from vortex-shedding meter on the second pipeline section.
Further, the vortex-shedding meter adjusts section using special taper.
Further, first pipeline section and the second pipeline section are all straight tube.
Further, the length of first pipeline section is 20m, and the length of the second pipeline section is 5m.
Further, each connecting portion is blocked using plugging material, guarantees No leakage.
The utility model has the advantages that compared with prior art, the utility model tooling uses vortex-shedding meter measurement of discharge, pressure adjusts dress
The method for adjusting outlet overbottom pressure is set, the air quantity and wind pressure of quickly and accurately survey aircraft air-conditioning device are capable of.
Detailed description of the invention
Fig. 1: the structural schematic diagram of the utility model；
Fig. 2: vortex-shedding meter measuring principle figure；
In figure: 1- vortex-shedding meter, 2- pressure gauge, 3- thermometer, 4- pressure-regulating device, the first pipeline section of 5-, 6- second
Pipeline section.
Specific embodiment
It is set forth now in conjunction with a specific embodiment of 1~2 pair of the utility model of attached drawing.
A kind of tooling for survey aircraft air-conditioning device air quantity and wind pressure, the outlet air applied to aircraft air condition device
Mouthful, including vortex-shedding meter 1, pressure gauge 2, thermometer 3 and pressure-regulating device 4, the front end of the vortex-shedding meter 1 pass through the
The connection of one pipeline section 5 is arranged on the air outlet of aircraft air condition device, and the rear end of vortex-shedding meter 1 connects the second pipeline section 6, vortex street stream
Meter 1 adjusts section using special taper, guarantees steady air current after Fluid pressure adjusting, as shown in Fig. 2, first pipeline section
5 and second pipeline section 6 be all straight tube, and the length of the first pipeline section 5 is 20m, and the length of the second pipeline section 6 is 5m；On second pipeline section 6
Pressure gauge 2, thermometer 3 and pressure-regulating device 4 are successively arranged on the direction far from vortex-shedding meter 1.
Working principle: when measurement, pressure-regulating device 4 is first passed through, the outlet overbottom pressure of aircraft air condition device is adjusted, works as pressure
When the pressure of 2 displays is the outlet overbottom pressure that air-conditioning device requires on table, the reading of vortex-shedding meter 1 is read, and record at this time
The pressure value that the temperature value and pressure gauge 2 that thermometer 3 is shown are shown；What vortex-shedding meter 1 was read is volume flow, according to temperature
Value and pressure value inquire the density value of this state point air fluid, are converted into mass flow, the as air quantity of air-conditioning device.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
