Correct selection of diaphragm couplings:
1. The diaphragm coupling consists of at least one diaphragm and two bushings. The diaphragm is fastened with a pin on the bushing and usually does not loosen or causes a backlash between the diaphragm and the bushing. Some production The two diaphragms are supplied; the three diaphragms are also supplied; the center has one or two rigid members; the two ends are connected to the sleeve.
2, the difference between the single diaphragm coupling and the double diaphragm coupling is different in handling various errors; in view of the demand for the diaphragm can be disorderly twisted; so the single diaphragm coupling is not used to The two diaphragm couplings can bend together in different directions; to compensate for the pain. Valve inlet pump 3, diaphragm coupling is a bit like a bellows coupling; in fact The method of transmitting the torque of the shaft is almost the same. The diaphragm itself is very close.

4, the diaphragm coupling is often used in the servo system; the diaphragm has a good torque rigidity; but slightly less than the bellows coupling.
5. On the other hand; the diaphragm coupling is very delicate; if it is misused in use or has no correct device, it is very simple to damage. Therefore, it is necessary to ensure the error within the acceptable scale of the normal operation of the coupling.
6. Choosing the right coupling is a key step in using the coupling; in the design phase, you have to think about the type of coupling.
