Bubble pressure test bench aperture tester
Bubble pressure test bench, also known as aperture tester, is an important detection and testing equipment widely used in the production and quality control of filter materials, filter cartridges, and filters. The following is a detailed introduction to the bubble table, including its characteristics, performance, and usage scenarios.
Introduction to Bubble Pressure Test Stand
The bubble table applies gas pressure to one side of the tested sample to observe the phenomenon of gas overflowing from the liquid surface on the other side of the sample, in order to evaluate the sealing performance or maximum aperture of the sample. The principle is based on the correspondence between gas pressure and sample aperture, and the relevant performance parameters of the sample can be obtained through calculation.
Characteristics of Bubble Pressure Test Stand
Easy to operate: The operation process of the bubble table is relatively simple, and users only need to follow the established steps to complete the test.
Fast testing: Due to the direct testing principle and rapid equipment response, the bubble table can complete testing in a short period of time, improving production efficiency.
Accurate data: By accurately measuring gas pressure and overflow conditions, the bubble table can provide accurate and reliable test data.
Low price: Compared to other high-end testing equipment, the bubble table is relatively affordable and suitable for small and medium-sized enterprises to use.
Easy maintenance: The equipment structure is relatively simple, and daily maintenance and upkeep are also relatively easy.
Performance of Bubble Pressure Test Stand
Wide testing scope: The bubble table is suitable for testing various filter materials, filter cartridges, and filters of different specifications and materials.
Pressure adjustable: The equipment is usually equipped with a pressure regulation system, and users can adjust the gas pressure according to their testing needs.
High degree of automation: Some high-end bubble tables have achieved computer control or automated operation, further improving testing efficiency and accuracy.
Data recording and analysis: The equipment can automatically record test data and perform data analysis and processing through software.
Application scenarios of bubble pressure test bench
Filter material manufacturer: During the filter material production process, the bubble table can be used to detect the pore size distribution and sealing performance of the filter material, ensuring product quality.
Filter cartridge manufacturer: The filter cartridge manufacturer uses a bubble table to conduct air tightness testing and aperture detection on the filter cartridge to verify its filtration effect and performance parameters.
Filter testing and certification: In the process of filter testing and certification, the bubble table is an important testing tool used to evaluate the sealing performance and filtration efficiency of the filter.
