Pneumatic and Hydraulic Automated Battery Burst Tester, how do they differ?


When it comes to Automated Battery Burst Tester, we will always see that the specification listed everywhere are according to two systems. These two systems include: 

• Pneumatic features 
• Hydraulic features 

Both these types of test systems are different from one another and are used to test the different features of the battery. They can be conducted using the same tester machine but have different settings and results from one another. 

Pneumatic Automated Battery Burst Tester


A pneumatic system means an energy typically present in the form of compressed air, which is converted into mechanical motion. 

The pneumatic system is relatively simple when it comes to be explosion-proof. Which is a great feature considering, safety is the utmost priority of the test. It also has a fail-safe protection system if the testing sample gets over-pressurized and an accident occurs. 

Depending on the actuator, the motion could be rotary or linear.

As mentioned before, there is compressed air present in the form of energy in this test, which means no working fluid is involved. The air requirement for the test is 80 PSI, while the pressure range is between 0 to 5,000 PSI.  The accuracy of the pressure transducer in this system is up to 0.01% FS. 

When it comes to system control accuracy, you would find it up to +/- 0.02 % FS. The pressurization rate of the pneumatic system ranges between 0.1 psi/sec – 200 psi/sec, which you can keep increasing to test the system as per your experimental requirement. 

The holding time for the machine during the pneumatic test is infinity. The machine requires 110 VAC, 60 Hz (220 VAC, 50Hz optional) of power to function properly. 

Hydraulic Automated Battery Burst Tester


A hydraulic system means that hydraulic power runs the mechanical operations where there is a cylinder of fluid motor involved. 

The actuating forces of the hydraulic system are higher and also provide a high stroking rate. Plus, the machine is highly stable, allowing you to conduct the test without any issue to determine accurate results. 

The machine’s mechanical output is in terms of: 

• Linear 
• Rotary 
• Oscillatory 

The hydraulic system exerts a greater force while the test is conducted as liquids are difficult to compress compared to air. However, this feature limits the acceleration. 

As mentioned before, the hydraulic system uses a liquid and not air, so there is no air requirement. However, you will require working liquids to conduct the test. The working liquids require include: 

• Water 
• Oil 
• Alcohol 

The pressure range for these liquids lies between 0 – 60,000 psi. Along with that, the pressure transducer accuracy is up to 0.01 % FS. At the same time, the system control accuracy is +/- 0.02 % FS. 
The pressurization rate for Hydraulic Automated Battery Burst Tester is between 0.1 psi/sec – 200 psi/sec. 

The maximum holding time for the hydraulic test is infinity, which means you can conduct the test at your convenience at all times. 

Conclusion 


The primary basis of how the test is conducted in the pneumatic and hydraulic systems is completely different. One system uses air while the other liquid changes everything that there is about the experiment. While one exerts more force, the other checks the mechanism of the batter. Together they complete the industry safety standard tests and are dependent on each other to gain complete customer trust when the results are forwarded.

What is a Cyclic Pressure Control System? How Does it Work?

Image
The APP Cyclic Pressure Control System  (CPCS) is a machine that generates cyclic pressure at a user-defined interval of minimum and maximum ranges. These ranges include atmospheric pressures of 5000 pneumatic systems (psi) all the way up to 60,000 (psi) hydraulic systems. What’s more, is the CPCS machine is fully automated and is controlled by a microprocessor. This ensures that the results are highly accurate and the pressure transducer monitoring gives adequate feedback. The user-defined target pressures include holding times, pressurization rates, and dwell times that can be performed under elevated temperatures for stimulating actual operational conditions. There’s also, a windows-based software that controls the entire pressure testing process and also depicts real-time test status during the entire process. Visually being able to look at the process step by step as it happens enables a better understanding of the expected results. The  Cyclic Pressure Control System   d
