balancing drum in centrifugal pump|What is balance drum and disk : companies Jun 15, 2006 · Please describe in detail the workings of a balance drum and balancing disc, both in combination in a centrifugal pump for axial thrust adjustment. I asked this question previously, but didn't get an answer that helped. Thanks! (0:03) Will a centrifugal pump work running backwards? (0:06) First thing you have to understand is that the veins on the impeller are shaped in order to fling the liquid being pumped up and out of the discharge. (0:19) So if the impeller is running backwards, the veins aren't running the correct way .

When 4 or more deviations are allowed to exist on a pump, early failure of the process pump is a virtual certainty. You will always pay a penalty for normalizing deviations.

In a high-pressure multi-stage pump, such as boiler feed water (BFW) pump, the number of impellers plays a crucial role in the overall performance and efficiency of the pump. To ensure smooth operation and reduce vibrations, balancing devices are incorporated into the pump design. One such balancing device is the balancing drum, which works in conjunction with balancing disks to maintain equilibrium within the pump system.

What is a Balance Drum and Disk?
A balance drum is a key component in a multistage centrifugal pump that helps to counteract the axial thrust generated by the impellers. It is typically located at the opposite end of the pump shaft from the impellers and rotates at the same speed as the impellers. The balance drum is designed to create a balancing force that offsets the axial thrust, thereby reducing wear on the bearings and increasing the overall efficiency of the pump.
Balancing disks are another important component in the pump system that work in tandem with the balance drum. These disks are strategically placed within the pump casing to help distribute the hydraulic forces evenly across the impellers. By utilizing a combination of balance drums and balancing disks, pump manufacturers can effectively minimize vibrations and ensure stable operation of the centrifugal pump.
Working of Balance Drum in a Centrifugal Pump
The balance drum operates on the principle of creating a counterbalancing force to offset the axial thrust generated by the impellers. As the impellers rotate and fluid is pushed through the pump, an axial force is produced in the direction of the pump shaft. This axial thrust can lead to uneven wear on the bearings and shaft, reducing the longevity of the pump.
To counteract this axial thrust, the balance drum is designed to rotate in the opposite direction of the impellers. This rotation creates a balancing force that helps to maintain equilibrium within the pump system. By effectively balancing the axial thrust, the pump can operate more smoothly and efficiently, reducing maintenance requirements and extending the overall lifespan of the equipment.
Benefits of Balancing Drum and Balancing Disk in Centrifugal Pump
The incorporation of balancing drums and balancing disks in a centrifugal pump offers several key benefits. Firstly, these components help to minimize vibrations and ensure stable operation of the pump, reducing the risk of mechanical failures and downtime. Additionally, by balancing the axial thrust within the pump system, the wear on bearings and other critical components is reduced, leading to increased reliability and longevity of the equipment.
