Abstract

PURPOSE: To detect a crack at its early stage in a diaphragm built in a pump or the like, by providing the body of the diaphragm with a fluid passage part and providing a detection port at an easily observable place outside the fluid passage part.
CONSTITUTION: A diaphragm body 1 is provided between an oil chamber 4 and a conveyed fluid chamber 5. The detection port 3 of the diaphragm body 1 is connected to a detection opening 6 provided in a pump body. The detection opening 6 is placed in a position easy for the operator to observe. When a piston 7 is moved back and forth, the diaphragm body 1 is deformed back and forth through oil A in an oil chamber 4 so that a conveyed fluid B is conducted under pressure in the direction of an arrow by the action of check valves 8, 9. When a crack is caused in the diaphragm body 1 due to its secular deterioration, the oil A or the conveyed fluid B is compressed by the reciprocation of the piston 7 so that the oil or the conveyed fluid enters into the fluid passage part 2 of the diaphragm 1 and flows out from the detection port 3 into the detection opening 6.
