Description
Известные устройства дл весовой тарировки расходомеров по способу гидравлического вывсш.-вапн ие обеспечивают достаточно выс.)кой точности вследствие ошибок при измерении веса расходуемо среды.The known devices for weighing the calibration of flowmeters by the method of hydraulic extraction-vapnie provide sufficiently high accuracy due to errors in measuring the weight of the consumable medium.
В предлагаемом устройстве применено плавучее приспособление - лодка, расположенна в масл ном бассейне, котора используетс дл компенсации веса всего оборудовани , а измеритель используетс только дл определени веса расходуемой среды.In the proposed device, a floating device is used - a boat located in the oil basin, which is used to compensate for the weight of all the equipment, and the meter is used only to determine the weight of the flow medium.
На чертеже изображена схема тарируюпл,его устройства.The drawing shows a diagram of tarryupl, its devices.
В бассейне 1, заполненном гидравлическим маслом 2, вывешена лодка 3, с размеш,енными на ней аккумул тором 4 давлени и отсеком .J, в котором размешены расходна магистраль, измерительные приборы , фотощит, содержаший киносъемочную аппаратуру, и осциллограф. После заправки аккумул тора 4 давлени сжатым воздухом через заправочный штуцер 6 подвижную часть стенда освобождают от заправочной линии. Дл определени веса расходуемой среды используют измеритель, содержащий весовую головку 7 и тензометрический датчик 8 усилий. К весовой головке 7 и тензометрическому датчику 8 усилий с помощью винта 9 прикладываетс усилие, равное весу сжатого воздуха, расходуемого за врем испытани . Дл устранени вли ни реактивной силы струи сжатого воздуха используют настраиваемое выхлопное приспособление 10. Показани весовой головки регистрируют на киноленте, а выходные сигналы, снимаемые с датчика S, подаютс на осциллограф.In the basin 1, filled with hydraulic oil 2, a boat 3 is hung, with the pressure battery 4 and a compartment .J placed on it, in which the flow line, measuring devices, photo shield containing the motion-picture equipment, and an oscilloscope are placed. After charging the battery 4 with compressed air through the filling nozzle 6, the movable part of the stand is freed from the filling line. To determine the weight of the medium to be consumed, a gauge containing a weighing head 7 and a strain gauge 8 force sensor is used. A force equal to the weight of the compressed air consumed during the test is applied to the weight head 7 and the strain gauge sensor 8 by means of the screw 9. To eliminate the effect of the reactive force of the compressed air jet, a tuned exhaust device 10 is used. The readings of the weighing head are recorded on a film strip, and the output signals taken from sensor S are fed to an oscilloscope.
