Pump overload trip
Thread Content
Can everyone help me figure out what this is?
Protective cover, coupling – I’m not sure what the original poster is referring to.
I would like to ask what that yellow thing in the middle is
Between the couplings are elastic blocks; it is a claw coupling. Poor coupling alignment can easily cause damage to the elastic blocks.
Elastic block; it seems that the alignment wasn’t proper during installation
Elastic blocks are available in several materials, usually rubber or polyurethane; they are considered wear-prone components
It’s likely that the coupling was damaged during use
After installation, it was not aligned properly; the coaxiality between the motor shaft and the pump shaft was poor, and as a result the coupling was damaged (it’s likely that the work was done by subcontractors: lol)
