Low-temperature Auto Impact Tester

JBDS-300C/500C Digital Display Ultralow-temperature Automatic Impact Testing Machine

Usage and Characteristics
Pendulum Impact Testing Machine is used to test anti-impact performance of metal material under dynamic load to judge the quality of material under dynamic load.This series of impact testing machines mainly include automatic impact testing machine and semiautomatic impact testing machine.They are easy to operate and high effective.Raising pendulum,impact and pendulum dropping are all controlled by electrical control. They can make use of spare energy to raise pendulum automatically and be ready for next impact test. Automatic impact testing machines also include room-temperature impact and low-temperature impact for clients’ requirements.This impact testing machine satisfies GB/T3808-2002and does impact test with metal material according to GB/T229-2007.Besides, it also can satisfy American standards and European standards, like ASTM E23-02a, EN10045,ISO148, ISO83 and other international relative standards.
This impact series of testing machines adopt large torque clutch and high-power motor to make the equipment more stable and no vibration when taking pendulum and releasing pendulum.

Advantages
1. The host of this machine adopts casting steel material, which can make the equipment run steadily in the whole process of test and get more accurate result.
2. Part of refrigeration adopts imported compressor or independent self-pressurization stainless steel liquid nitrogen tank.
3. After completing low-temperature test, impact testing machine delivers samples to impact automatically. The whole process only needs less than 4 seconds. It improves working efficiency and accuracy.
4. The host is PLC automatically control, which has high stability and strong anti-interference ability.
5. This machine adopts large torque clutch and high-power motor,which make equipment stable and no vibration in taking and putting pendulum process.
6. Computer control and all the results of test can be saved in computer, be printed and be uploaded.
