Familiar with filter core integrity tester operating methods and procedures

With the increase in the demand for a wide range of filter cartridges, filter manufacturers continue to increase, and the types of filters produced are also varied, such as air filter cartridges, precision filter cartridges, and stainless steel filter cartridges . Of course, the increase in production volume will inevitably be accompanied by an increase in quality requirements. The mainstream testing equipment in the filter industry is a filter integrity tester. The following is a simple sharing of the working process of this tester based on experience:
1, the main workflow is as follows:
Air source → Gas control and display → Air pressure setting and display → Air pressure check → Test start → Intake → Hold pressure and display → Collect data → Record print → Gas bleed
2, specific operating methods and procedures:
1. Plug in the unpowered power supply and connect the air source. After completion, connect the test tube.
2. Press the power at the beginning of the power (will display the relevant information on the screen), press the air source button to vent (the pressure gauge shows the pressure of the air source).
3. Press the hole (filter size) button of the filter element you are testing (press after selecting) (the screen filter aperture shows the value).
4. Set and adjust the bubble point pressure (for specific values, refer to the filter insert) (the screen setting pressure shows the value).
5. Set the pressure check (repeated several times to confirm the set pressure).
6. Press the newly wetted filter cartridge and clamp the housing.
7. Press the start button (completed into full-time, pressure data collection, printing, deflation) (the screen running status mark flashes continuously).
8. When the maintenance pressure is displayed at 0Mpa (the screen operation status is not blinking instantaneously), the exhaust button on the filter case is loosened and the filter element is removed after confirming that there is no air pressure.
9. At the end of the test, press the power switch and air supply button.
Precautions:
1. The filter element must be fully saturated and moist. Due to infiltration, the liquid film on the hole cannot be completely formed, resulting in gas leakage. The test result will fail.
2. During the test, it should be noted: whether the filter element is in close contact with the turnover socket, whether it is tight between the shell and the shell or between the shell and the seat. If leakage occurs, the pressure of the holding pressure will drop, and the test must be re-installed.
3. This device is a live instrument and should be used in a dry place. Do not get wet.
4. Key Note: The air pressure in the filter housing must be released before the housing clamp is loosened and the filter element is removed, otherwise it may cause accidents.

The above is a brief introduction to the work process and precautions. Of course, how to operate is also combined with the respective equipment composition and work flow of each factory, but it is generally as described above.
