Stringent local testing makes for peace of mind all round

Stringent local testing makes for peace of mind all round

Whether it be hydraulic power units and lubrication systems or components, systems and services for test benches and test systems to engineering support and simulation, HYDAC has the testing part covered.

According to HYDAC Australia Project engineer Kent Paulsen, HYDAC can execute testing for any product or system it has built. 

“We generally test as much as we can. This is so we can have peace of mind when one of our pieces of equipment is on site doing its job, ie, we can be secure in the knowledge that there will be no issues,” Mr Paulsen says.

“HYDAC has normal testing power packs and tanks etc. that it uses to test hydraulic power units and lubrication skids. 

“As to diesel applications, it rents flow bins with diesel in them.”

Local testing wins the prize

Mr Paulsen highlights that HYDAC rented and connected a flow bin that it filled with automotive diesel to test a diesel testing unit designed to test diesel fuel injectors at a power plant. 

“The customer came through, providing an opportunity to use the skid at our premises and give back some feedback and pointers as to what they wanted changed,” he points out. 

“The unit was also set up on an HMG 4000 while we executed factory acceptance testing. This meant the customer also got a bit of an impromptu training session to understand how the system works and what to expect.”

Factory acceptance testing on-site 

HYDAC executes factory acceptance testing (FAT) as a matter of course.

Overall, this entails inspecting and testing units with specialised testing equipment at HYDAC’s premises to resolve any concerns prior to dispatch.

Testing with on-site tools and resources enables HYDAC to review functionality and procedures and assess results so it can assure customers that equipment is of a high quality, to contractual specification, and fit-for-purpose once on site.

Hydraulic power units and lubrication systems pressure tested

Pressure testing and flushing to an ISO 4406 standard suitable for all customer applications applies to HYDAC’s hydraulic power units and lubrication systems.

Product knowledge is accumulated through high-performance test rigs, wind tunnels, and other TÜV certified equipment.

Performance tests in terms of heat exchange, pressure drop, air resistance, corrosion, fatigue resistance, noise, thermal shock, and vibration are also executed and analysed.  

Components, systems and services for test benches and test systems

As to test benches and test systems, “speed” is the main competitive factor, a HYDAC spokesperson points out.

“The time required to perform tests must increasingly become less while the complexity and range of test requirements increase,” the spokesperson says.

“HYDAC’s onto it. We have the know-how to speedily develop the best technological and economical solution for any situation.”

HYDAC’s service includes engineering and simulation of the test system; energy-efficient design; active cooperation in close development partnership; pressures of up to 1,000 bar; monitoring of a hydraulic system; commissioning and service; and worldwide technical and commercial support through a global presence.

Engineering support and simulation

Gmbh, HYDAC’s engineering service provider, has been entrusted with the mission of assisting customers in the development of electro-hydraulic machines and systems. 

“We develop tailor-made and easy-to-use simulation tools for specific fields of application, with user guidance and a range of functions that are specially adapted to requirement,” the spokesperson says.

Hydraulic simulation

Hydraulic simulation makes it possible to perform extensive analyses and optimisations of systems in early development phases, minimising time-consuming and costly re-design and work in the trial field.

Multi-body dynamics

Multi-body simulation makes it possible to perform analyses of the interplay of forces and motions, even in the case of complex kinematic structures. This information provides valuable input for the drive system’s design.

Real-time simulation

Whenever simulation models need to communicate with electronic hardware components or when people interact with computational models using suitable operating elements, the simulation needs to portray the corresponding processes in real-time, the spokesperson says.

“Performing simulations of this type requires specialised expertise, which HYDAC has developed over the years.”
