Abstract

The invention relates to water filter element testing, in particular to a bubble-pressure leakage detecting method. According to the bubble-pressure leakage detecting method for membrane filaments, a glass jar filled with an alcohol solution is adopted, and an unwinding roll for winding undetected membrane filaments and a winding roll for winding detected membrane filaments are fixedly arranged at the inner bottom of the glass jar. The unwinding roll is connected with a first pneumatic motor through a first chain, and the winding roll is connected with a second pneumatic motor through a second chain. A push rod is arranged between the unwinding roll and the winding roll, and a rocking bar is connected to the push rod. By being soaked in the alcohol, the membrane filaments filled with air can bubble; air pressure is related to the pore diameter, and the larger the pore diameter is, the lower air pressure is required by bubbling; the smaller the pore diameter is, the higher air pressure is required by bubbling. By the bubble-pressure leakage detecting method, when bubbles appear above the push rod, the membrane filaments with leakage points are pushed by the push rod to ascend to a high position, and accordingly observation and marking are facilitated.

Description

technical field [0001] The invention relates to a water filter core test, in particular to a bubble pressure leak detection method. Background technique [0002] With the continuous development of water filter elements, they are not only used in drinking water, but also in the pharmaceutical industry. The most critical component in the water filter is the membrane filament. [0003] Batch comprehensive testing cannot be carried out on the traditional film production line. Contents of the invention [0004] The object of the present invention is to provide a bubble pressure leak detection method for membrane filaments to solve the above technical problems. [0005] The technical problem solved by the present invention can adopt following technical scheme to realize: [0006] The bubble pressure leak detection method of membrane filaments includes a glass cylinder, which is characterized in that an unwinding roller winding undetected membrane filaments and a winding rolle...
