Regarding the problem of shaft alignment of high temperature centrifugal pumps
Thread Content
There is a high-temperature centrifugal pump. The motor and pump body are connected by a hexagonal elastic ring, and the fluid temperature is 280 degrees. During operation, the hexagonal elastic ring is easily damaged. What could be the reason? Both cold centering and hot centering have been tried.
There is a problem with pump alignment. After the alignment is good, fix the screws on the pump base. When the pump is running at high speed, the vibration of the pump can easily cause the base screws to loosen.
Is the gap between the couplings a bit large and the contact surface roughness not high? It’s something like the picture below, right?
The problem of alignment is that although it is an elastic block coupling, the alignment standard is relatively low, but poor alignment has a great impact on the life of the module! !

The claw coupling is made of three cast claws. Post-finishing machining can easily cause the three claws to be unequal. Even if there is no fault, the cushion pad will break very quickly! It is recommended to replace it with a pin coupling or a German KTR coupling! If there is space, using a diaphragm coupling is also a good choice! Germany’s picture below
Why can’t I see the picture? Please post again!
