Progress through research 

The in-house SCHLICK Test Center allows measurable success

 

Know-how and innovation are much discussed in today`s society. At Düsen-Schlick, these terms have been the tradition for a long time and are the basis of our corporate culture. Decisive components are the permanent development and design of new process technology and the investment in product ideas and additional services. While doing so, the very specific requirements of our customers are at the forefront.

The Schlick Test Center (STC)

Engineers and technicians use the STC to carry out stress and endurance tests on newly developed nozzles and also for quality testing on the whole range.

Due to he increased demand for customised measuring, testing and optimisation solutions, these measuring and testing services have become an official part of the range of services offered by Schlick.

 

At its over 500 m2 premises, the STC brings together the very latest measuring and testing equipment. The following facilities are available for the evaluation of sprays from one-, two- and multiple-substance nozzles and for the evaluation of customers’ materials:

 

  • Dynamic drop measurement system (DUAL-PDA)
  • Ultra-modern atomizing test tunnel for the upscaling of nozzle performances
  • Extraction to the drop measurement system for the measurement of customer’s materials
    (also for solvent-containing agents as e. g. alcohol)
  • Spray distribution testing equipment
  • High-pressure pumps, even for higher viscosity ranges
  • Viscosity testing equipment
  • Sound level meter
  • Heatable pressure tank
  • Large compressor station for fine atomisation of media up to 3.500 l/h
  • Circulation pumps for measuring and supplying up to 2000 l/min at the usual mains pressure
  • Digital precision flow meter and manometer for compressed air and water

 

Schlick uses a drop measuring device based on the dual PDA principle (PDA = Phase-Doppler Anemometry) in order to precisely meet specially defined operating parameters. This device works with a 5 Watt continuous-light laser(argon ions). The contact- and interference-free measurement procedure is able to determine not only local speeds but also, among other things, the relevant drop sizes and volume current densities.

Combined with existing and flexible test stations, this means that even highly complex spray and coating situations can be measured, compared and optimised and therefore this technology delivers reproducible results for individual requirements. This is true no matter how specific the application.

By using the DUAL-PDA in a state-of-the-art spray tunnel, measurements can also be carried out for problematic media containing solvents using the specially developed suction. This is a big plus for the development of customer-specific solutions.

The services offered by Schlick range from simple measurements with the appropriate records to detailed testing reports with discussion of the results and suggestions for improvements to processes. The results obtained can be immediately put to use in the development of prototype solutions. Schlick has a database of over 40,000 tested solutions to help it in this task.



 

The SCHLICK Test Center carries out measurements,
conducts analyses and produces documentation for the following areas:

  • Drop size
  • Drop speed
  • Flow rate density
  • Spray distribution
  • Rheological behaviour of liquids
  • Sound level
  • Cleaning trials
  • Comparative drop measurement
  • Comparative performance measurement
  • Throughput measurement

 

We also offer services in testing of materials: 

  • Tensile testing according DIN EN ISO 6892-1
  • Metallographical tests by using light microscopy
  • Spectral analysis of austenitic stainless steel
  • Surface roughness determination
  • Optical 3 D measuring machine
