FIELD: machine building.
SUBSTANCE: invention relates to methods for determination of explosion protection efficiency in the test model of an explosive facility. Installed in a box is a model of an explosive facility, and on its internal and external perimeters there are video cameras for video surveillance. Video cameras are made in explosion-proof design, and outputs of the video cameras through inner cavity of spacers are connected to the unit by means of which there is performed recording and registration of current processes of parameters' change in the model. One records, by means of a system of analysers of recorded waveforms of current processes, technological parameters' change in the model of an explosive facility. In the ceiling part of the model one makes an aperture closed by an explosion-proof element installed freely on three elastic pins, wherein one end of every pin is rigidly fixed in the model ceiling, while on the second end one fixes a horizontal bar. Between the explosive fragmentation element and the aperture one installs a three-dimensional pressure sensor in explosion-proof design whose output is connected to the input of the recording and registering equipment, and on both sides of the pressure sensor one installs temperature and humidity sensors, controlling termal-humidity mode in the model. Outputs of the sensors are connected to the input of the recording and registering equipment. Inner and outer surfaces of the model enclosures are glued with strain sensors, outputs of which are also connected to the input of the recording and registering equipment. After processing of the obtained experimental data one forms a data base on development of an emergency situation in case of an accident at the explosive facility and draws up a mathematical model forecasting prevention of the emergency situation in case of an accident at the explosive facility.
EFFECT: higher efficiency of process equipment protection against explosions by increasing the efficiency and reliability of bursting elements' response.
