Bench for springs testing SPTE 80-100
Purpose
■ testing of relief valve springs
■ testing of pressure springs
■ testing of other springs of various purposes
■ force measuring and measuring of changes in linear dimensions by
testing of the pressure and tension springs
Construction
■ the bench is equipped with a precision-build electromechanical
drive with a smooth control of the movement speed of the active
crossbeam and microprocessor control device
■ has the ability to remember, store, use the information about spring
parameters based on identification number
■ evaluates the test results (calculation of the permissible permanent
deformation)
■ displays the entered and received data on the display in the form of
test reports and, if necessary, archives them
Advantages
■ equipped with a high-precision linear encoder
■ possibility to test different spring diameters without the change of
equipment and readjustments
■ does not have stand-alone power units
■ on request, the test bench can be equipped with sensors for testing
the tension springs
■ control is carried out from a freestanding control panel equipped with
a touchscreen operator panel
Principle of operation
In automatic (when entering an identification number) or adjustment
mode:
■ threefold compression (extension) of the spring with the followed
release and measurement of the permanent deformation
■ consistent spring load up to a given force with stopping and outputting
to a digital indicator of the deformation (or spring height)
