Description
Single station N2 leak test for SOFC Stacks, with manual or automatic loading/unloading. Different sizes and models of stacks can be tested, by means of related fixtures for their connections.
Principle of measurement: nitrogen mass flow measurement, by way of Tecna measuring devices.
The bench provides a single station, assembled on a welded painted steel frame with cover panels and automatic door. The cabinet containing the electric switchboard is on the left-hand side of the bench, while the process components, including the measuring devices, are located on the right-hand side. The access to the stations is protected by safety light curtains. Only electrical supply, air and nitrogen supply are needed to run the machine.
The measuring device – with possibility to have a touch screen display at sight, so that it is possible to look into the values of pressure/flow rate of the test phase – is installed in the bench.
The fixture is automatically actuated and allows the coupling between the bench and the stack under test.
The bench incorporates an industrial PC which performs HMI functions while supervision of the process is made by a PLC. The software is configurable so that it is possible to:
- Set machine parameters
- Create different recipes, according to required test parameters
- Manage the automatic cycle as well as the manual cycle
- Set counters and production data
- Manage levels of access
