High Pressure – Leakage Test Bench
Resistance test at overpressure
The system is used to test for leakage at overpessure. In this application example, the test items are self-contained refrigerated air conditioner used for cooling trolley cabinets in aircraft kitchens. The refrigeration circuit of the test items consists of different compoonents such as pipes, condenser, repoiler, compressor, rupture disk, pressure switch, valve and other which are tested for leakage. The system is controlled via a PC with measurement data acquisition hardware and measurement and control software under LabVIEW.
Technical data
| Test pressure | 0…100 bar |

| Ambient pressure | 800…1200 mbar |
| Ambient temperature | 0…50 °C |
| Ambient humidity | 0…100 % rH |
may change for your application.
Tests
Resistance test (Proof Pressure Test):
In this test, the resistance of the refrigeration circuit is checked at overpressure. Nitrogen is used as test gas.
Pressure Switch Test:
The pressure switch test checks the proper functionality of the pressure switch in the refrigeration circuit.
Applications
- Leakage measurement on vehicle components
- Leakage measurement on refrigeration units
- Leakage measurement on enclosures
- Leakage measurement on valves and claps
