Pneumatics control medical bed test rig
Parker Pneumatic cylinders, valves, filter regulators and associated controls are all used in a test rig for the prototype of a new electrically adjustable medical bed.
Parker Pneumatic cylinders, valves, filter regulators and associated controls have been specified for the pneumatic control system on a test rig for the prototype of a new electrically adjustable medical bed, designed and manufactured by medical product and services specialists, The Verna Group To ensure patient safety and comfort, it is necessary for this type of product to be subjected to rigorous testing for a series of loadings to BS EN1970-2000

New series of Schrader pneumatic couplings
Parker Pneumatic has further extended its industry standard Schrader Range of quick acting pneumatic couplers with the introduction of the Euro Series.
The Verna Group commissioned special purpose machinery designer and manufacturer, TEC Engineering (Rochdale) to conduct these tests.
TEC Engineering, in turn, commissioned Parker Pneumatic distributor Economatics to design the pneumatic system and supply the necessary components for a test where a load of 2175N a load in excess of the required standard had to be applied to a particular area of the bed.
These components, comprising a 63mm-bore 125mm-stroke cylinder, filter/regulator unit, precision regulator, pressure gauges, isolation valve, stop/start valve, pilot/pilot valve, counter, flow regulators, end of stroke sensors and all tubing and fittings, were then incorporated into the test rig to the Economatics design requirements.
The test called for the load to be applied 10,000 times and was successfully completed in under 8h.
Using the same test rig, further testing was carried out to apply, 1000 times, a load of 750N to the lifting pole.
This test, also, was concluded successfully.
"The Parker/Economatics partnership provided us with everything we needed in terms of system design and reliable components for the test rig", commented TEC Engineering, Design Engineer, Graham Caine.
"Our customer can now be confident that their new, electrically adjustable bed will be safe and comfortable for patients". Request a free brochure from Parker Hannifin ...
