Questions regarding the laminated coupling on the pump
Thread Content
What does it mean by the compensation values on the pump coupling diagram: an axial maximum of ±3.6 at an angular displacement of 0.167°, and an axial maximum of ±1.8 at an angular displacement of 0.67°? What is the reference value of these numbers for installation alignment?
It is this coupling that can meet these requirements; the smaller the alignment deviation of the coupling, the better
The greater the angular error between the two axes, the smaller the axial distance that the diaphragm can compensate for, which indicates that the diaphragm’s compensatory capacity has certain limits; if it primarily compensates for angular errors, its ability to compensate for axial errors will be reduced. During alignment, this value should be regarded as the allowable limit error; in the event of damage, it can also be used to determine liability between the parties.
These things need to be calculated when designing couplings
This is calculated by the manufacturer based on the strength and shape of the diaphragm material, the forces acting on it (direct forces and fatigue strength), its dimensions, and its maximum allowable deformation
