Description
Technical Field

Background
Diaphragm pumps are a common type of industrial pump, whose diaphragm is an important component of the isolation medium and the pump body. Proper installation of the diaphragm can ensure normal operation and service life of the diaphragm pump. The diaphragm is fixed to the pump body, and in general, the diaphragm of the diaphragm pump is fixed by bolts and clamps. In the case of bolting, the bolts need to be tightened, but not over tightened, to avoid damage to the membrane sheet. In the case of clamping, the clamping plate needs to be screwed down, but is not too tight.
For example, chinese patent publication No. CN203702510U discloses a diaphragm clamping structure, which comprises a guide rod (1), a first clamping plate (2), a first diaphragm (3) and a second diaphragm (4) which are mounted in a fitting manner, a second clamping plate (5) and a fastening nut (6), wherein the inner sides of the first clamping plate (2) and the second clamping plate (5) are respectively provided with a concave groove formed by concave downward grooves, the first diaphragm (3) is provided with a convex part positioned in the concave groove of the first clamping plate (2), and the second diaphragm (4) is provided with a convex part positioned in the concave groove of the second clamping plate (5). The protruding part of the diaphragm is embedded into the groove of the clamping plate, when looseness occurs in the movement process of the diaphragm clamping structure, the protruding part in the middle of the diaphragm is matched with the groove of the clamping plate, so that the force of outwards pulling the diaphragm can be born, the pulling force born by the small hole in the middle of the diaphragm is greatly reduced, and the diaphragm is not easy to tear, thereby achieving the effect of protecting the diaphragm.
However, when the conventional diaphragm clamping device is used, the diaphragm is fixed by using the fastening nut and the screw thread at the front end of the guide rod in a matched manner through the action clamping plate, and when the fastening nut rotates to contact the clamping plate II, friction is easily generated between the fastening nut and the clamping plate II, and the service life of the clamping plate II is easily influenced by long-term friction.
