Filter element sealing performance testing device

The invention provides a filter element sealing performance testing device, which comprises a bracket, an air inlet mechanism and an air outlet mechanism, and is characterized in that the air inlet mechanism and the air outlet mechanism are mounted on the bracket; an air flow test channel is formed between the air inlet mechanism and the air outlet mechanism, and the air flow test channel penetrates through a to-be-tested filter element; the detection pieces are arranged on the inner side and the outer side of a to-be-detected filter element respectively, and the support is used for driving the air inlet mechanism and the air outlet mechanism to move in the vertical direction of the to-be-detected filter element so as to cooperate with the detection pieces to detect the sealing performance of the to-be-detected filter element. According to the filter element sealing performance testing device, gas detection is adopted to replace isopropanol soaking detection commonly used by a liquid filter element, pollution
