Complete power supply, control, and remote monitoring system for test benches

The hydraulic power units we offer are based on the latest technical solutions and designed according to individual Customer requirements.

Hydraulic systems must be designed from the very beginning with the investment conditions in mind, which requires, among other things, knowledge and experience as well as cooperation with the Customer. Our plant in Łaziska Górne deals with the design, production, assembly, and service of hydraulic systems and circuits. Thanks to our comprehensive approach, we have implemented many hydraulic systems and test benches for various industries.

For the automotive industry—a company supplying systems for passenger cars, commercial vehicles, and industrial solutions—we manufactured a hydraulic system supplying test benches.

The designed central supply system for the benches consists of two 2000 l oil tanks and four pump assemblies built on the basis of piston pumps with displacements of 140 and 70 cm³/rev., driven by motors with powers of 110 and 55 kW, respectively.

The hydraulic system is used to supply three lines of test benches located in different parts of the plant. Finished products, such as steering gears, are tested on these benches.

Technical parameters of the system:

• maximum oil flow: 700 l/min
• nominal pressure: 280 bar
• maximum operating pressure: 315 bar

The construction of the power unit was based on PONAR Wadowice hydraulic elements, including: S type check valves, DB and DBW type pilot-operated relief valves, DBDS type direct-operated safety valves, BS type accumulator safety and shut-off blocks, URZS type 2/2-way valve logic valves with ULZS type covers.

The supply system is also based on hydraulic safety blocks consisting of a steel body, URZS logic valves with a ULZS type cover mounted in the P and T lines. The application of safety blocks is intended to cut off pressure and return lines in emergency situations. Placing pressure and flow sensors in the safety blocks detects oil pressure and flow disturbances.

The project also included the execution of a hydraulic pipeline network with a total route length of 315 m, as well as a cooling system based on a water chiller with a thermal capacity of approx. 400 kW, maintaining the oil temperature within the required range of 46°C ± 3°C.

The entire central hydraulic system was covered by the dedicated monitoring and prediction system “PONARpredict“.

As part of this project, PONAR Wadowice designed and built two twin systems in two production plants in Europe.
