Test stand for manifold bar

The leak test system was developed for testing manifold bars up to a length of 750 mm (= 13 secondary outlets). The test medium is air. The test is carried out under water with manual evaluation. The test pressure can be max. 6 bar (up to 10 bar possible) and is individually adjustable. The device under test is positioned manually on the test system. Previously, the sealing elements for the secondary outlets were set manually in the system depending on the type of manifold bar. Adjustment to various inter-axle distances of the secondary outlets is possible.
 
The test air is supplied via the movable sealing element. These processes are all carried out above the water level in dry state. For the test, the described clamping device with the device under test is placed under water by raising the water level through immersing a displacer high enough so that the test piece is completely under water. Minor leaks are detected by rising gas bubbles. With a manually adjustable thermostat, the water quench can be heated to a certain temperature. The test procedure is carried out automatically and flexible in terms of time. This system has been designed for a high level of flexibility and provides short conversion and adjustment times. The system is suitable for testing small to large series.

The test parameters input is realised in a customer-specific manner from permanently programmed values via manually changeable ones up to the type-specific test database. The test results are also evaluated customer-specifically, from simple signalling of the test result via signing to a database of the test results with automatic certificate generation.
