Breathing gas cylinder hydrostatic testing machine using external measurement method Air breathing apparatus cylinders Carbon fiber air breathing apparatus cylinders Alloy steel cylinders for positive pressure breathing apparatus Fully-wrapped composite cylinders with an aluminum inner liner and carbon fiber winding

The testing device is composed of parts such as a control cabinet, a water volume collection and pressurization system, a pressure test water jacket, and a weighing electronic scale (optional).
The control software of the testing device adopts LabView industrial control software. The computer is used to complete tasks such as weighing the gas cylinders, setting the parameters for the hydraulic pressure test, printing the hydraulic pressure test report, and viewing the results of the hydraulic pressure test.
The designed maximum working pressure of the testing device is 80 Mpa. The control accuracy of the actual test pressure is not lower than 50 Psig, and the actual water level measurement accuracy is not lower than 0.1 g. When the testing device is in operation, it has a high degree of operation automation. After entering the serial number of the test gas cylinder, it only requires pressing a few buttons to complete the process from weighing to finishing the hydraulic pressure test under normal circumstances. During the test, it can dynamically display the relationship curves of time/pressure, time/water volume, pressure/water volume in the test process in a graphical manner. The testing device stores all the data of the test process, and users can view all the test data and various test curves of the tested gas cylinders whenever needed.
