Low temperature tank series for impact testing machine

The CDW type impact test cryogenic instrument (tank) is a product developed and developed by our company based on the requirements for low-temperature devices in GB/T229-2007 "Charpy Pendulum Impact Test Method for Metal Materials" and in conjunction with various regulations on deep-temperature refrigeration, which is suitable for low-temperature physical and chemical testing of metal products.The low-temperature impact test is a very important mechanical property test for metal materials. The accuracy of the test temperature directly affects the reliability of the test data.This equipment adopts single/cascade compressor refrigeration technology, utilizes the principle of thermal balance and cyclic stirring method to achieve automatic uniform cooling and constant temperature of the sample, and can fully meet the technical indicators stipulated in the national standard GB/T229-2007.This equipment is simple and convenient to operate and has high working efficiency. It is the most ideal sample cooling and constant temperature equipment in metal low-temperature impact testing.It can also be used for other low-temperature detection and testing work.The three-element cascade ultra-low temperature refrigeration cycle technology is used to greatly expand the temperature difference of the system cycle operation, and can obtain a lower refrigeration temperature (-100°C rapid refrigeration) than the traditional two-stage compressor cycle.
