Embodiment Construction

[0024] The method for determining the corresponding relationship between the filter absolute filtration precision and the bubble breaking point involved in the present invention is applicable to the laminated filter using the groove on the filter sheet as the filter flow channel (see figure 2 , image 3 ). By measuring the maximum depth of the flow channel on the filter sheet, the absolute filtration accuracy of the filter sheet is determined, and the designed test method is used to complete the data measurement of the bubble break point, and the corresponding relationship between the absolute filter accuracy of the filter and the bubble break point is determined by curve fitting.

[0025] Such as figure 1 Shown, concrete steps of the present invention are as follows:

[0026] (1) According to the test needs, select the tested filters of various specifications.

[0027] (2) According to Figure 4 As shown in the principle, the tested filter 1 is installed on the test tool...

Abstract

The invention discloses a method for determining the corresponding relation between absolute filter precision and a bubble breaking point. The method comprises the steps as follows: (1) aiming at a laminated filter; (2) determining the absolute filter precision of a filter disc by measuring a maximum depth value of a circulating channel on the filter disc; (3) simulating a practical using state of the filter disc through an experiment design; (4) measuring the bubble breaking point of the filter disc through a test; and (5) carrying out depth measurement and bubble breaking point measurement by selecting the filter discs with different maximum circulating channel depths, and determining the corresponding relation between the absolute filter precision and the bubble breaking point. According to the method, the characteristics of the laminated filter are fully utilized, the test can be repeated, the required test equipment is greatly simplified, the test cost is greatly reduced, and the test time is saved.

Description

technical field [0001] The invention relates to a method for determining the corresponding relationship between the filter's absolute filtration accuracy and the bubble breaking point, which is suitable for a laminated filter using a groove on a filter sheet as a filter flow channel. Background technique [0002] Filtration accuracy is an important performance parameter of filter products. According to the definition, the absolute filtration accuracy is the diameter of the largest hard spherical particle that the filter can pass through under the specified experimental conditions. In the traditional absolute filtration accuracy test method, special glass beads are added to the test medium and passed through the tested filter, and the maximum particle size measured in the filtered medium is taken as the absolute filtration accuracy of the filter. This test is a destructive test. The process contaminates the filter itself, and excess material introduced during the test remain...
