Description
Technical Field
The invention belongs to the technical field of filter element bubbling tests, and particularly relates to a filter element bubbling test device.
Background
The filter fineness of the filter is strictly measured by a multiple pass test (international standard ISO 4572) in which standard dust (american AC dust) is added to red oil in a dedicated test apparatus, and the diameter and number of particles in the filtered red oil are measured by a particle counter to determine the filter fineness and filter efficiency of the filter.
Another method of measuring the filtration accuracy of a filter is a bubble test. The bubble experiment can determine the void size of the porous material and the product thereof, and the quality of various filter materials and finished filter elements thereof is evaluated by adopting the bubble experiment method. The maximum pore size and the average pore size can be provided within the area range to be measured, and the sizes of the damaged pores and the manufacturing defects other than the normal pore size of the filter material can be measured. This test is also referred to as a porosity test or a filter integrity test.
The mathematical model of the bubbling test is based on the theory of capillarity. One of the "air permeable materials" is a "bent capillary" to be abstracted as a cylindrical capillary. If the capillary tube is immersed in a liquid, the liquid in the capillary tube will rise until it reaches equilibrium with its gravitational force, a phenomenon known in fluid mechanics as capillarity.
When the test liquid is soaked and filled in the gaps among the fibers of the filter material, clean air is filled into the other end of the test liquid, and the pressure required by the replacement process is measured at the moment when the gas replaces the liquid in the holes. If the surface tension of the liquid (including the height of the liquid surface) against which this pressure opposes is equal to it, the size of the hole can be reasonably characterized.
But current filter core bubbling test device is usually for driving the filter core rotation through electronic part, and the test liquid of filter core bubbling test device is isopropanol, for inflammable and explosive liquid, and the setting up of electronic part can make the holistic explosion-proof performance of device hang down.
