Abstract
An automatic measurer for engineering dewar static heat load comprises a measuring balance, a host machine which is equipped with an automatic measuring software for heat load, a display, a keyboard and a printer. The data-out port of the measuring balance is connected with the serial port of the host machine, and the keyboard is connected with the input port of the host machine, and the output terminal of the host machine is connected with the display and the printer; the keyboard can adopt a numeric keypad or a common computer keyboard. The utility model realizes the automatic measurement of engineering dewar static heat load, and the utility model has the characteristics of simple and rapid operation, low using cost and good practicability; the utility model also saves manpower and enhances efficiency; thus the utility model is especially suitable to duly monitor the index of the heat load in the process of batch production of the engineering dewar.
Description
Technical field
The utility model relates to engineering Dewar static heat load automatic testing equipment.
Background technology
The static heat load is one of important indicator of military detector/Dewar component of decision and refrigeration machine Adapter Property, also is the means of judging detector/Dewar component internal vacuum indirectly.Although the heat load value of Dewar is in product design process, can determine its representative value by structure and selection, but still there be departing from of actual value and theoretical value in the actual manufacture process, especially after the product vacuum performance descends, because the rapid rising of convection heat transfer' heat-transfer by convection, directly cause product heat load index exceeding standard, so that product failure.Thereby be necessary to be necessary to realize in the static heat loading index, particularly batch production process of actual measurement single products the automatic measurement of heat load index.
At present, the quality test method of deciding is usually adopted in the load of engineering Dewar static heat, i.e. weight method, to workpiece from mass M
1Drop to mass M
2Required time t carries out timing, by measuring the liquid nitrogen dissipation quality in the pipe in the Dewar, calculates the static heat load value according to formula then.Usually adopt stopwatch to workpiece from mass M
1Drop to mass M
2Required time t carries out timing, and measuring process must have personnel to guard, and promptly wastes time and energy, and lacks measuring accuracy again.
Summary of the invention
Deficiency at above-mentioned prior art existence, the engineering Dewar static heat load self-operated measuring unit that the utility model provides, it is made up of measurement balance, the main frame that the automatic Survey Software of static heat load is housed, display, keyboard, printer, and the data-out port of measuring balance connects the serial ports of main frame; Keyboard is connected to the input port of main frame; The output terminal of main frame and display, printer join.Keyboard can adopt numeric keypad or common computer keyboard.
The device that the utility model provides has following advantage: the user only need pre-set and measure starting point and measure end point, to be measured is placed on the measurement mechanism, just can carry out data acquisition automatically by the automatic Survey Software of static heat load, after setting end point, stop data acquisition automatically, and form time and figure-of-merit curve, after selecting two quality point arbitrarily on the curve, calculate the heat load value automatically, and result of calculation printed, the utility model has been realized the automatic measurement of engineering Dewar static heat load, have simple to operate, fast, use cost is low, practical characteristics, saved manpower, improved efficient, be specially adapted in the engineering Dewar batch production process timing monitoring the heat load index.
