Impact Testing Machine
Low-temperature impact test of metal materials, the mechanical properties of a very important test, test temperature directly affect the accuracy of the reliability of test data. CDW-type low-temperature impact test instrument (trough) is a company under the GB/T229-2007 "metallic materials Charpy pendulum impact test method" (to replace the GB/T229-1994 "metal Charpy notched impact test method"), the right low-temperature device requirements to meet the provisions of the deep-temperature refrigeration, while the latest development, the development of low-temperature physics and chemistry applied to metal test the latest products. The device uses single / cascade compressor refrigeration technology, the use of heat balance principle and cycle mixing method to achieve uniformity of the sample auto-cooling, constant temperature, can fully meet the national standard GB/T229-2007 technical specifications set forth in . This equipment is easy and simple, efficient, low-temperature impact testing of metal specimens in the best cooling, constant temperature equipment. Can also be used for other low-temperature testing and trials. The use of triple cascade ultra-low temperature refrigeration cycle technology, which greatly expanded the work of the system loop temperature, accessible than the traditional two-stage compressor of the refrigeration cycle of a lower temperature (-100 ℃ rapid cooling). At the same time, the equipment has been adopted across the new environment-friendly refrigerant for future inspections and repairs provide a convenient, is currently the most mature area of impact testing of ultra-low temperature refrigeration apparatus
