FLOW TEST BENCH TECHNICAL DATA: • Pressure peak: • Max flow: • DAS: INSTRUMENTATION: • N° 7 pressure transmitters: n° 5 relative: n° 2 differential: • N° 2 temperature transmitters: • N° 2 ultrasonic flow meters • N° 1 function generator The B_23201 test bench is designed for the characterization of valves or other fluid dynamic components used in aerospace industry, using a water/glycol mixture as a fluid. The machine is able to perform: • flow and/or pressure keeping tests; • proof test. Using a specific hydraulic circuit, this machine is able to generate a test cycle consisting of maintenance and controlled pressure ramps in accordance with the following standards: SAEJ343 - ISO18869 - ISO1402 - PED. Essentially, the bench consists of three trolleys: • Flow generation units; • Component test unit; • DAS console. • All operations are controlled by the control console, which also incorporates the DAS data acquisition and test report recording. 0÷20 barg ± 623 mbardiff 0° ÷ 150° C, cl. AA 0,27÷27 l/min, accuracy ± 0,05% f-s 0 1 ÷ 5 MHz, 20 ppm, 1kΩ SAFETY DEVICES: • Anti shock bench casing • Interlock on test compartment hatch • Mushroom emergency buttons • Automatic interruption of the test in case of, breakage, component leakage or malfunction of the bench • Over pressure switch for water lines • Over pressure valves for air line SUPPLIES: • Electric: • Process fluid: • Compressed air (if p<6 bar): • Nitrogen (if p>6 bar): DIMENSIONS AND WEIGHT: Console: • L, p, h: • Weight: Fg: • L, p, h: • Raw weight: Uut: • L, p, h: • Raw weight: COLOR: • Standard: NOTE: • Customized on demand. 400 Vac - 50 Hz 3F+N+PE, 3 + 1 kW 150 l (tank) 50 Nl/min. 50 Nl/min

The connection system consists of two (or more, on request) flexible supply pipes that convey the fluid to the component to be tested and one return. 5 relative pressure transducers, 2 differential pressure transducers, 2 flow meters and 2 temperature sensors, with acquired signal, allow the detection of the characteristic curves of the component under test. • The test bench is provided with an acquisition system equipped with a PC and a National Instruments DAS system. • The PC software, in addition to setting up the test, allows you to parameterize and control every aspect of the test to...
