JBDW-300 Computer Screen Display Pendulum Impact Testing Machine with super low temperature chamber

1. General Introduction

The JBDW – 300 Computer Screen Display Pendulum Impact Testing Machine with Super Low Temperature Chamber is a specialized piece of equipment used to test the impact resistance of materials under super – low temperature conditions. It is commonly employed in industries such as electronics, aerospace, and materials science to evaluate the performance of computer screens and other materials in harsh environments.

2. Key Features

a. Computer Screen Display

• It is equipped with a computer – controlled screen that provides real – time display of test data, including impact energy, impact force, and deformation. This allows operators to monitor the test process accurately and obtain precise results.
• The display also enables easy parameter setting, such as test speed, pendulum angle, and temperature control.

b. Super Low Temperature Chamber

• The super low temperature chamber can reach extremely low temperatures, which simulates the actual working conditions of materials in cold environments. This is crucial for testing the impact resistance of materials at low temperatures, as the mechanical properties of materials often change significantly with temperature.
• The chamber has good thermal insulation performance to ensure stable temperature control during the test.

c. Pendulum Impact Testing

• The pendulum impact testing mechanism provides a standardized and repeatable way to apply impact force to the test specimen. The machine can accurately measure the energy absorbed by the specimen during the impact, which is an important indicator of its impact resistance.
• Different pendulum weights can be selected according to the test requirements to meet the needs of various specimens.

3. Technical Specifications

a. Temperature Range

• The super low temperature chamber typically has a temperature range from – 40°C to – 196°C, allowing for a wide range of low – temperature tests.
