The structure of the elastic diaphragm coupling is relatively simple, with two and a half couplings, one set of diaphragms, and several sets of bolts. The diaphragm is one of the main structures of the elastic diaphragm coupling, but there are also quite a few people who consider the diaphragm as an accessory because it is a consumable item. The bolts, nuts, and elastic pads in the elastic diaphragm coupling can be referred to as the accessories that make up the elastic diaphragm coupling. They are the same as the diaphragm and require regular inspection and replacement.
Diaphragm, because it is made of stainless steel and has good durability, will only show damage after a long period of use on machinery and equipment. Many elastic diaphragm couplings can be used for more than 2 years, but some companies show varying degrees of damage after one week of using elastic diaphragm couplings.
The usage function and lifespan of the diaphragm depend on the detailed operation situation, whether the installation is in place, whether the torque is overloaded, etc. These are important factors that affect the lifespan of the diaphragm.
During operation, bolts, nuts, and elastic pads may exhibit different situations of wear, fracture, and drop, especially in the bolt part. It is common for them to cause bending and fracture of bolts due to excessive torque.
