What is the HYDAC charging and testing Block F+P?

The HYDAC charging and testing block F+P is used to charge and test back-up-type hydraulic accumulator stations. It has connections for the charging and testing unit FPU-1 and the pressure gauge. HYDAC supplies the following safety devices to secure against excess pressure and/or excess temperature increases:

What is a HYDAC system?

1. GENERAL In a back-up version with nitrogen bottles to increase the efective volume The HYDAC system approach creates a HYDAC system of, for example, bladder or piston accumulator stations, by integrating individual HYDAC components. The modular design of the accumulator stations enables HYDAC to incorporate all customer requirements.

What is a piston accumulator?

max. 3. PISTON ACCUMULATORS a sealing system adapted to the particular application. The piston floats on two guide rings which prevent metal-to-metal contact between the piston and the accumulator wall.

How can HYDAC calculate accumulator volumes?

Taking the customer’s own operating data into account, HYDAC can calculate the required accumulator volumes using the accumulator simulation program: z ASP – Accumulator Simulation Program. Please read the relevant operating instructions for the individual HYDAC components! 2. MODEL CODE 3. EXAMPLES OF ACCUMULATOR STATIONS 3.1.

How to increase gas volume in hydraulic accumulator?

To increase the gas volume in the hydraulic accumulator, nitrogen bottles are used in back-up form. The advantage of doing this is that smaller accumulators can be used for the same gas volume and the costs of the entire volume package can be reduced. 87
