The search for innovative
solutions can create true progress only if it is accompanied by a rigorous
testing system that simulates the conditions of operation. Indeed, practical
application is the most stringent and most demanding overseer for quick
couplings.
Working in the sector for 60 years and addressing the needs
of a global, multi-sector market, Stucchi has perfected its process of
developing new ideas and products for hydraulic circuits, which includes
testing for correct operation in a variety of conditions that reproduce
conditions in the end application.
Stucchi therefore includes a
state-of-the-art testing area, which
enables the necessary tests to be carried out for product development and
certification of use, as well as meeting specific verification requirements
requested by customers. Before being placed on the market, new couplings
undergo testing required by the international ISO 18869 standard (Hydraulic fluid power – Test methods for
couplings actuated with or without tools) and, when requested, specific
tests required by manufacturers.
The parameters that Stucchi
measures during these tests are related to:
· ●
Pulsation pressure – to test
resistance of the coupling over time for pressure cycles that may occur in the
most demanding applications;
· ●
Burst pressure – to check the
safety margin between the operating pressure and the breaking pressure;
· ●
Flow – the maximum volume of fluid that can pass through the quick
coupling under particular operating conditions is checked, establishing the
maximum limit suggested to ensure optimum performance;
· ●
Pressure drops – to measure
pressure drops caused by turbulence during the transit of fluid through the
coupling and thus allow the system builders to correctly size the pumps to
achieve the desired performance specifications;
· ●
Coupling/decoupling force – the
force required to couple and decouple the quick coupling is measured;
· ●
Spillage – an inspection is carried
out during decoupling to detect any oil leakage and the quantity of oil is
assessed. A correctly designed quick coupling minimises, if not completely
eliminates, spillage, providing a greater degree of safety in the workplace and
prevents environmental contamination.
All the information obtained during these tests is included
in the data on the product sheets, which
provide all the information required for the correct use of the quick coupling.
Stucchi’s commitment to research, development and testing of
its products has guaranteed a continual flow of quick coupling solutions for 60
years. Contact us to find out more.
