The shaft sleeve of the graphite bearing in the shielded pump has burned out
Thread Content
If the shaft sleeve of the graphite bearing in a canned pump is damaged, what will happen if it is continued to be used without repair? Solve
Using it in a continuous manner will wear out the motor’s internal insulation sleeve, which will make repairs difficult.
The rotor will hit the shield, causing damage to the pump
It is recommended to replace it; failing to do so will result in greater losses and poses safety risks
The bearing friction increases, causing the pump motor to overload and trip frequently, ultimately leading to complete damage of the bearing.
Is the bushing worn out? How did you know? Could it not be by looking at the TRG table? Generally, if this gauge exceeds the green zone, it indicates that the pump needs to be repaired; the repair involves replacing the bearings and shaft sleeves. Thrust discs, 3 types – it’s not just a single shaft sleeve; at least that’s the case here. If you ignore the issues once they reach the critical stage, eventually the shielding sleeve surrounding the rotor will get worn out, and that means the pump is practically unusable. It’s also very dangerous, as flammable and explosive substances can end up inside the coils. Isn’t that dangerous? It’s recommended to carry out repairs promptly
It is recommended to replace it immediately! If it is not replaced, it will cause severe vibration and accelerated wear at the least, and may even damage the shielding sleeve in more serious cases. The repair costs are even higher! And the repair time is long!
When choosing a shielded pump, it is recommended to opt for those from Dalian Empire; although their price is higher, their quality is indeed reliable. When a graphite bearing is worn or damaged to a certain extent, the bearing detector will indicate this. If it isn’t addressed in time, an excessive bearing clearance can lead to damage to the shielding sleeve, which creates problems – and simply replacing the bearing isn’t enough to solve the issue.
If this pump is used without maintenance, it will have to be scrapped!
