CDW-60 impact test low-temperature instrument
PIC-(CDW-60 impact test low-temperature instrument)
Introduction to Structure and Working Principles:
This equipment consists of a cascade refrigeration compressor main body, control box, cooling tank, cooling medium circulation system, automatic alarm device, and other parts.
After the equipment is started, the high-temperature compressor automatically starts (the timer cannot be adjusted for 8 minutes), and the refrigeration system enters the official working state. The refrigeration compressor operates continuously, and when it approaches the set temperature, the electronic control system automatically adjusts the cooling and heating rates to slow down the cooling rate and achieve constant temperature. Stirring can continuously circulate the cooling medium in the cooling tank to achieve uniform and consistent temperature inside the tank.
Performance description:
The DWC-60 impact test low-temperature tank is the latest compressor refrigeration equipment developed by our company in accordance with the requirements for low-temperature devices in GB/T229-2007 "Metal Charpy Pendulum Impact Test Method". This equipment adopts a cascade compressor refrigeration technology, utilizing 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 temperature control indicators specified in the national standard GB/T229-2007. The compressor is imported from France's Taikang. This equipment is easy to operate and has high work efficiency, making it an ideal sample cooling and insulation equipment for metal low-temperature impact tests. It can also be used for other low-temperature detection and experimental work.
