Piping and assembly of a cylinder test bench.

Piping and assembly of a cylinder test bench.

Aggregate construction and assembly services from one source - synergies in terms of safety, function and high durability.

Earlier this year, our Austrian subsidiary EUROFLUID won a contract from a leading manufacturer of heavy transport and construction machinery for the piping and bolting of a cylinder test bench at the customer's premises. This was to be integrated into the central hydraulics unit in the main factory as quickly as possible so as to reliably inspect large quantities of cylinders prior to installation.

15 m pipelines without deflections.

The project lasted seven months, during which initially the production of the hydraulic unit for leakage oil feedback was scheduled and then all piping operations and installation services were carried out by our technicians. A horizontal fastening rail of 15 m in length and length-adjustable, made of a profiled tube and custom-made at the EUROFLUID plant, was used for this purpose as no other fastening option was available. Deflections of the hydraulic pipes were avoided despite this considerable distance.

The biggest challenge was the integration of a highly dynamic test bench into an existing hydraulic system, which itself contained several test benches. During the integration it was also necessary to accommodate pressures of up to 350 bar as well as dynamic pressure fluctuations without compromising safety and functionality. As a result, we opted not for the standard cutting ring technology but for WALFORM fittings to satisfy the high demands.

More reliability in cylinder testing.

The additional test bench gives our customers valuable insights and information about the durability improvements. Special screw types and special fastening rails provide an optimum safety guarantee and leakage oil feedback. All safety-relevant factors were taken into account during the project and guaranteed during installation.
This is an outstanding result, which is due not only to the professional assembly but also to the committed joint designs with our client.

The key information about the project:

  • Implementation time: February to August 2019
  • Client requirements: Integration of a customer-side cylinder test bench into the central hydraulic system
  • Our solution: Piping: WALFORM Eaton in the required screw connection dimensions, EUROFLUID hydraulic unit for leakage oil return: delivery rate 12 l/min, electric motor 1.1 kW, pressure (max.) 30 bar, ALU tank volume of 63 l
  • Special feature: highly dynamic test bench with pressure ranges up to 350 bar
