Case histories

Laboratory preparation for tests on anti-seismic devices for building and infrastructure

Testing

Qualification and acceptance

Hydroservice has accompanied the customer  in the design of a machine necessary for testing the anti-seismic devices. At the same time the hydraulic circuit of the machine control was studied, which can develop a vertical load of 70 MN  and horizontal up to 20 MN, in dynamic and static condition. In particular the main equipment for carrying out tests on support devices and anti-seismic isolators is capable of developing up to 18 MN of dynamic force.
Every equipment is managed by sophisticated electronic control devices and dedicated software with an exclusive acquisition system which records up to 12 channel simultaneously with different sampling frequency.

What Hydroservice has developed

Hydroservice provided the entire hydraulic system is composed of a power plant with 6000 L tank, two storage systems, each one consisting of a 300 L piston accumulator and 12 additional nitrogen cylinders,
several control manifolds with all the necessary interlocks (valve, servovalve, control and management tools), the whole piping (both regid and flexible), various derivation manifolds for simplified construction of the machine edge.
It was also provided all the electrical part as well as the machine control pulpit equipped with an integrated control system.
Hydroservice also followed all the installation and commissioning activities of the hydraulic system and, in collaboration with the customer's technicians, of the machine in general.

The result

The hydraulic system designed and built entirely by Hydroservice guaranteed the performance required by the customer's specifications who was able to start the system within the established time and perform the tests for which the system was designed.
