Description

Technical Field

[0001] The utility model relates to the technical field of filter element detection equipment, in particular to a large-size filter element bubbling test tool for a high-precision carbon fiber stock liquid filter. Background Art

[0002] The filter element bubble test is a non-destructive test method used to evaluate the structural integrity of filter elements. By measuring the pressure at which bubbles begin to form in water or other liquids at a specific pressure, the test determines the maximum pore size of the filter element and determines whether the filter element meets technical specifications. The bubble test utilizes the surface tension that must be overcome when gas is discharged through the pores of a wet filter element, resulting in the equilibrium pressure, which is the corresponding measure of the maximum pore size.

The middle part of the support frame 7 is rotated to connect the lead screw 9, and a detection motor 8 is provided on the top of the support frame 7. The output shaft of the detection motor 8 is connected to the lead screw 9. The lead screw 9 engages with a pressure block 13, and a driving nut is provided on the pressure block 13.

The bottom surface of the pressure block 13 has the rubber sealing layer, and a through hole is provided in the middle of the pressure block 13. A hose 1301 is provided on the top of the pressure block 13, and the through hole is connected to the hose 1301. The other end of the hose 1301 is connected to the air pump. There are guide rods 10 on both sides of the support frame 7, and the guide rods 10 slide up The dragging platform 12 is dynamically connected, and a support wheel 1201 is provided at the bottom of the dragging platform 12. The support wheel 1201 rolls to the side of the support frame 7, and the dragging platform 12 can pass through the drop port 201.
