Technical description
This test rig is designed to perform cyclic pressure tests in water.
Main functions
This test bench is designed to perform cyclic pressure tests in water, on one or more products simultaneously. It simulates water hammer in pipes or tests the ageing (in accelerated mode) of components. It checks for leaks by pressure drop or flow detection. It can also be used to perform pressure tests on components subject to special legislation.
The shape of the stress curves can be set. The number of test cycles and their sequence are programmable.
The air purge is automatic and verified by the system stiffness measurement.
Operating mode
The purpose of a test is to apply static pressure cycles, according to a trapezoidal profile, in a more or less elastic product.
- Installation and clamping of the sample
- Connecting the supply hose and purge hose
