An article to read the use of burst pressure tester, test principles and pressure unit conversion relationship

In the field of new energy batteries, it is crucial to guarantee the safety and reliability of batteries. AndBurst Pressure Tester(also known asPressure Bursting Tester,Burst Tester) serves as a key piece of test equipment that can help us accurately assess the burst pressure of a battery. In this article, we will provide an in-depth introduction toBurst Pressure TesterHow to use, testing principle and pressure unit conversion relationshipto help you better understand and applyPressure Bursting TesterThe

Ⅰ.Burst Pressure TesterMethods of use

1. Preparation

• assureBurst Pressure TesterThe power and gas sources have been properly connected and installed and calibrated according to the instructions.
• According to the type and specification of the battery product, choose the appropriate tooling fixture to fix it in the test chamber.
• Set the desired maximum burst pressure value, test time and pressure loading rate and other parameters.

2. Pressurized test

• Place the battery sample to be tested securely in the test chamber of the tester, ensuring a tight seal.
• Start the instrument and gradually increase the pressure in the sealing chamber by slowly pressurizing it.
• Closely monitor the instrument test interface and battery product status in the event of leakage, cracking or rupture.blasting instrumentIt will stop pressurizing immediately and record the highest pressure value at this time, which is the actual burst pressure of the battery product.

3. Security

• Due to the risk of battery explosion during testing, operators are required to wear protective equipment such as protective eyewear and gloves.
• Burst TesterAn explosion-proof enclosure or protective chamber should be provided to avoid injury to personnel due to uncontrolled testing.
• The test site should be well ventilated to prevent the accumulation of harmful gases.

4. Analysis of results

It should be noted that, due to the blasting test has a certain degree of danger, the operator must be professionally trained, familiar with the safety regulations, and strictly comply with the protective measures to ensure that the test process is safe and controlled.

Ⅱ.Burst Pressure TesterTest Principle

Burst Pressure TesterBy applying different pressures to the battery, the bursting of the battery under different pressures is observed and recorded. It is based on the following principles for testing:

• Data logging and analysis:Burst Pressure TesterCapable of recording the bursting condition of the battery under different pressures and generating corresponding data and graphs for subsequent analysis and evaluation.

• Pressure sensors:Burst Pressure TesterBuilt-in high-precision pressure sensors are used to accurately measure the pressure change of the battery during the test.

• Control system:The tester's control system is capable of controlling the pressure applied to the battery and monitoring the battery's condition.

For example, new energy rupture disc bursting test is an application of pressure-resistant bursting test. Soft pack battery cells are an important part of power batteries. Soft pack battery cells play a key role in the performance and efficiency of power batteries by enhancing energy density, increasing design flexibility and improving thermal management.The rupture disc bursting test for flexible pack batteries is designed to assess the ability of the battery's aluminum-plastic film to withstand damage under the impact of an explosion, and to reduce the risk of an explosion by releasing the pressure through structural rupture in the event of a failure to improve the battery's safety performance.

III. Pressure unit conversion relationship

in usingBurst Pressure TesterWe often come across different pressure units. The following are some common pressure units and their conversions:

Commonly used units:

Common units of pressure include pascals (Pa), kilopascals (kPa), megapascals (MPa), bars (bar), and kilograms.

Conversion relationships:

1 kilopascal (kPa) = 1000 pascals (Pa) = 0.001 megapascal (MPa) = 0.01 bar = 0.01 kilograms.

JCGK can provide the gas from a few kPa to 3MPa.Pressure Loading Test EquipmentTest ranges can be customized for high pressures up to 5MPa.

Knowing and understanding the conversion relationship between these units helps us to better understand and apply theBurst Pressure Testerof the test results and make accurate judgments and assessments.

IV. Summary

Burst Pressure TesterIt plays a key role in the field of new energy batteries and improves strong support for the safe design of batteries.In the continuous development and innovation of new energy battery technology, JCGK's series ofNew energy testing equipmentwill continue to play an important role in safeguarding the operation of the battery and the safety of the application.
