Hollow fiber ultra-filtration membrane washing test machine

The utility model relates to a hollow fiber ultra-filtration membrane washing test machine and relates to a washing test machine for offline washing and testing a hollow fiber ultra-filtration membrane, which is characterized in that a medicine barrel (1) is connected with one end of a pump valve (F3) and a pump bypass valve (F5) through two medicine-barrel valves (F1) and (F2), one end of the pump valve (F3) is connected with one end of a washing test pump (3), the water outlet end of the washing test pump (3) is connected with a pump valve (4), and another end of a source-water rotor flow-meter valve (F10) and a rotor flow-meter bypass valve (F11) is connected with a forward valve (F12) and a reversing valve (F13). The direction of washing liquid can be changed through the control of thevalves so as to realize the washing in different directions; the membrane test can be performed while the membrane is washed, so that the quality of the system membrane can be known without being installed into the system. The rate of finished product is improved, and the production cost is reduced.
