FIELD: test equipment.SUBSTANCE: test bench is designed for tests of jet devices. Stand has a jet device, vessel connected with jet device nozzle through pressure line, hydraulically connected with jet device nozzle and fluid discharge line is hydraulically connected with jet device diffuser, means of generating pulsed gas pressure in pressure line and control and registration system. In reservoir there are jet device and pressure main line connected with creation of pulse pressure gas in it, and inside main line there is unit for measuring displacement of liquid level. Medium discharge line is connected with receiver equipped with device for measuring volume of liquid supplied into receiver. Monitoring and registration system includes one sensor for pulsed pressure in pressure line, one sensor for pulsed pressure in suction and mixing chambers of jet device, as well as synchronisation unit of data origin and data recording unit. Measurement, movement of liquid level in discharge line unit and device for measuring volume of water into receiver are made in form of pistons connected to units for measuring their linear displacement.EFFECT: wider range of equipment.1 cl, 2 dwg |
