Energy efficient central pressure supplyCopyright: ifas
The central pressure supply (ZDV) of the ifas supplies hydraulic power as required in the test facility. With a maximum total output of Pel = 473 kW, the ZDV is able to provide volume flows of up to 840 L/min. Maximum pressures of 400 bar can be reached. Various operating modes can be selected during operation, allowing energy-efficient operation. For this, primarily adjustable axial piston pumps and variable speed fixed displacement pumps are used.
The water and particle content is continuously monitored during operation. Particles are filtered in the high pressure, return and secondary circuit.
The executing companies of ZDV were:
- HYDAC (Hydraulics)
- Wagner and Müller (control technology)
- Heinricht GmbH (pipeline construction)
The ZDV is used in various projects. For example, the power can be used on surrounding machine beds in the ifas test hall for valve or piston test benches.
