If the diaphragm is not installed in place, the sealing performance of the pump is poor, leakage is easy to occur, the influence on the working stability and the service life of the pump is large, and in a serious case, the pump cannot pump liquid directly.
Currently, the diaphragms used in pumps are rubber-in-metal molded. In the conventional diaphragm installation, an operator usually holds a disc-shaped rubber part of a diaphragm with fingers and then turns the diaphragm by hand to screw the diaphragm to a device one by one, the manual operation is limited by the space size of product parts, the assembly efficiency is often not high, when the mass production is carried out, the long-time manual screwing can cause extreme fatigue of both hands of the operator, even lead to the safety risk of hand skin abrasion, the diaphragm is easy to damage under the condition, and industrial rubber particles are inevitably adhered to the rubber diaphragm, emit unpleasant odor and are difficult to clean, and black stains which cannot be cleaned are remained on the hands for a long time.
It is worth noting that another problem with manual installation is that: the installation torque cannot be provided greatly, and the torque consistency of batch products cannot be ensured due to different operators, so that systematic quality problems may occur in the whole product. Attempts have been made to screw the membrane using a screwing tool. However, the membrane does not have a portion that can be engaged by a turning tool, such as a wrench, as is the case with conventional screwable elements, such as nuts. In addition, for a diaphragm with a smooth surface, although tightening can be performed by sucking the diaphragm with a vacuum chuck, the vacuum suction force is limited and not too much torque is transmitted, which causes the diaphragm to be untightened and loosened during operation, thereby affecting the stability of the pump.
