Abstract

The utility model discloses a flat membrane testing device which comprises a liquid mixing barrel, a testing assembly and a standard water tank, one side of the liquid mixing barrel is connected with the testing assembly through a high-pressure pump with a pipeline, the other side of the liquid mixing barrel is connected with the standard water tank through a low-pressure pump, and a flat membrane to be tested is arranged in the liquid mixing barrel. A mounting assembly is arranged between the liquid mixing barrel and the flat membrane to be detected; and the mounting assembly comprises a mounting frame and a mounting seat, inserting blocks which are symmetrically arranged are movably inserted into the two sides of the mounting frame, and corresponding inserting grooves are formed in the surface of the mounting seat. According to the installation assembly with the L-shaped slope insertion block and the spring return piece in linkage, when the installation base is vertically inserted, the insertion block automatically shrinks, rebounds and is locked, the flat membrane can be disassembled only by pushing the return piece when replaced, compared with traditional screw fixing modes and the like, the installation and replacement process of the flat membrane is greatly simplified, the operation efficiency is improved, and the operation cost is reduced. And meanwhile, the manual operation difficulty is reduced.
