The filling system uses compressed air as the power source. Through the pneumatic booster pump, the agent is driven by proportional and automatic reversing reciprocating pressurization at high pressure for transportation and filling, which greatly improves the filling speed. The electronic scale can set the filling weight. When the delivery flow reaches the set value, a signal is transmitted to the filling high-pressure pneumatic ball valve through the flowmeter, and the valve is automatically closed to stop the filling. For vacuuming, a large-flow vacuum pump with a flow rate of 1 L/S is used to quickly achieve vacuum in the filling bottle, improving the filling speed and the purity of the agent. When filling with nitrogen, it first passes through the pressure reducing valve to reduce to the required pressure to improve the filling stability and prevent overshoot. Open the nitrogen valve to inject nitrogen and observe the pressure gauge. When the set pressure is reached, close the nitrogen valve, and the entire filling process is completed.
The control software of the test device adopts the LabView industrial control software. The computer is responsible for weighing the gas cylinders, setting the parameters for the hydraulic pressure test, printing the hydraulic pressure test reports, and viewing the results of the hydraulic pressure test.
The designed maximum working pressure of the test device is 51 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 test device is in operation, it has a high degree of operation automation. After inputting the serial number of the test gas cylinder, it only takes a few key presses to complete the process from weighing to finishing the hydraulic pressure test under normal circumstances. During the test, the relationship curves of time/pressure, time/water quantity, pressure/water quantity during the test process can be dynamically displayed in a graphical manner. The test device saves 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.
