PIT-D dual beam Charpy

Impact   energy

150J,   300J, 450J, 600J, 750J

Functions

This   machine is used for measuring the Charpy impact resistance of metal and other   materials

Standards

ISO   148, EN10045, ASTM E23, GB/T 229, GB/T 12778, GOST 9574

Features

·          One-body cast frame design of seat   and column provide high stability and rigidity

·          Front and rear columns are   symmetrical. Pendulum arm is designed of cantilever beam support, with simple   structure and high machined precision

·          Apply high precision bearing with   small friction. Absorbing energy without loading is less than 0.3%

·          Double reduction gear system   replaces old style drive system with high efficiency and avoiding   transmission failure

·          Round pendulum head design reduces   windage losses to the most

·          High rigid pendulum arm prevents   axial and transverse vibrations

·          Exchangeable pendulum is simple to   change to satisfy impact energy of 150J, 300J, 450J, 600J, 750J

·          Electromagnetic release of pendulum   hammer and electromagnetic clutch for locking the pendulum and raising it to   its initial position. A damper is equipped to prevent strong bump when   clutching

·          Full-closed enclosure with high   safety to prevent broken sample from splitting. Protective screening has   interlock door. When the door opens, most operations can’t work to avoid any   wrong operation

·          Apply SIEMENS industrial PLC to   control pendulum, and high precision Japanese made NEMICON rotary encoder to   measure striker real time position. The whole system is stable, reliable and   accurate

·          A big touch screen monitor may   real-time displays striker angle, impact energy, toughness, and other   parameters.  User can input specimen   data and other information such as company information into this monitor.   When connected to a printer, user input information and test results will be   printed

·          Optional computer with software control   is available to realize semiautomatic operation. Operator only need charge   specimens. Others can be controlled by software

·          Optional specimen feeding system is   available. Combined with computer and software, fully automatic operation can   be realized

·          Optional cooling system is   available to satisfy cold specimen test down to -180

Specimen   collection and filtering device

 

·          Motorized   device is used for collecting broken specimens after impact, instead of   manual cleaning, which fully prevents striker from getting stuck

·          Unique   specimen filtering function: automatically judge and transport qualified and   unqualified specimens to different collecting box

Professional   test software

This   software is designed specifically for testing metals to Charpy standards.   Software provides an easy-to-use method for gathering, calculating and   storing impact test results. The test result can be printed and exported to   EXCEL for review.
