Hydraulic test bench with metrology gauge calibrated annually

The metallurgical testing of the wheels has already been completed.

The hydraulic system is controlled by the HYD CUT OFF [hydraulic system cut-off] switch, mounted on the collective stick of the right-hand seat, and by the HYD TEST [hydraulic system test] switch, mounted on the centre console.

Hydro testing to ensure capability in handling high levels of pressure.

Hydro testing to ensure capability in handling high levels of pressure.

The testing pump may be powered by a power fluid, where the power fluid may be delivered from a power fluid source.

The test system drives the test device with a first hydraulic motor, which is itself driven by a first hydraulic pump.

At the output of the test device, a second hydraulic pump absorbs the power from the test device, and drives a second hydraulic motor, which in turn drives the first hydraulic pump.

in connection with any hydrostatic pressure test or equivalent test.

The power fluid source may be located at a location remote from the testing pump.

  A vibration test device equipped with the hydraulic actuator is also provided.

The hydraulic circuit includes a hydraulic pump, a hydraulic motor, and a hydraulic fluid reservoir containing hydraulic fluid.

A hydraulic engine with a water wheel is designed as non-polluting underwater generating plant.
