Scrape Abrasion Tester For Testing Lab Description and Specifications for Lab Tenders
Scrape Abrasion Tester For Testing Lab Workshop.
Scrape Abrasion Tester - For Testing Lab
The Scrape Abrasion Tester for Automobile Cables
consists of a scraping wire, which abrades the test specimen under a
fixed load of 7 N and a suitable mounting platform for clamping the test
specimens on.
The scraping wire is in form of a round
spring wire with a diameter of 0.45 mm, and secured rigidly to a
carrier. Motion to the carrier is given through an oscillating arm,
which runs on grease sealed type ball bearings minimizing friction and
giving uniform load on the carrier. The oscillating arm is moved with
the help of a motor operated crank and connecting link to give a total
stroke length of 20 mm. An arrangement is provided to lift the carrier
at both the extreme ends of the stroke. A low voltage supply system with
relay is provided to automatically stop the motor as soon as the
scraping wire comes in contact with the core of the specimen under test.
A pre-set type four-digit electronic counter with memory backup is
provided to record the number of strokes and also to stop the motor
automatically after a pre-set number of strokes.
