[0002]
Existing detection methods for hollow fiber membranes usually use a peristaltic pump to draw water and connect the pressure gauge to pass through the membrane wire. Due to the use of a peristaltic pump, there is a problem of inaccurate test results caused by pressure pulse fluctuations; at the same time, the existing components to be tested Generally, the method of opening the plastic mold to inject the shell of the plastic component is used. This method is costly, the packaging process is complicated and time-consuming, and the water connection test is used to obtain the flow of water passing through the membrane per unit membrane area and unit pressure and calculate the flux. This method produces data results relatively slowly
