Check the equipment: Ensure that the bubble table is in good working condition, all components are intact and tightly connected. Preparation of medium: Prepare an appropriate amount of industrial ethanol or isopropanol as the test medium according to the test requirements. Prepare the sample: Cut and process the filter element or filter material to be tested according to the requirements, ensuring that the size and shape meet the test requirements. Operation steps of bubble test bench
Preparation for startup of bubble test bench: Adjust the status of the bubble table to zero and close the drain valve.Select the type of specimen (filter element or filter material) and place the "test" and "blow dry" switches in the "test" direction.Sample installation for bubble test bench:For the filter material, cut it into appropriately sized discs and immerse them in isopropanol liquid for 3-5 minutes. Then place it in the fixture and clamp it, ensuring it is submerged in the appropriate position below the liquid level (such as 13mm).
For the filter element, immerse it in industrial alcohol for 5 minutes. Then install the filter element in the test chamber, with all components sealed except for one intake duct, and ensure that the filter element is at an appropriate height from the liquid level (such as 13mm).Bubble test bench setting parameters: Connect the power and start the bubble table.
According to the test requirements, set the test parameters such as test pressure, test time, etc. by operating the buttons and display screen.Bubble test bench begins testing: Turn on the air pump, adjust the adjustment knob and fine-tuning knob, and slowly increase the air pressure.Carefully observe the surface of the sample, and when the first continuous stream of bubbles escapes from the porous surface, press the "Enter" key to record the pressure value. Continue adjusting the fine-tuning knob to create 3-5 continuous bubbles on the surface of the sample, and press the "Enter" key again to record the pressure value.
Result processing of bubble test bench: Compare the pressure values of the first string of bubbles and 3-5 consecutive strings of bubbles. If there is a significant difference between the two, it may indicate a defect in the test piece.Based on experimental data, evaluate the structural integrity of the filter cartridge and the maximum pore size of the filter material and cartridge.
Print report: Select the test result on the display screen and enter the number you have set. Select to save or print test results, press the "Enter" key, and the printer will start and print the test results. Precautions for Bubble Test BenchSafe operation: When operating the bubble table, safety operating procedures should be strictly followed to prevent accidents from occurring.Equipment maintenance: Regularly maintain and upkeep the bubble table to ensure it is in good working condition.
Data recording: During the experimental process, the experimental data and observation results should be accurately recorded for subsequent analysis and evaluation. The above information is for reference only, and the specific usage method may vary depending on different models and manufacturers of bubble tables. Before use, please refer to the equipment manual and follow the manufacturer's instructions for operation.
