A balancing drum plays a crucial role in the operation of a centrifugal pump, especially when it comes to adjusting axial thrust. When combined with a balancing disc, the balancing drum ensures smooth and efficient performance of the pump. In this article, we will delve into the workings of a balance drum and balancing disc, their functions, and their importance in multistage centrifugal pumps.

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.

Centrifugal Pump Balance Drum

The balance drum in a centrifugal pump is a key component that helps in counteracting the axial thrust generated during operation. Axial thrust is the force exerted in the axial direction of the pump shaft due to the pressure difference between the suction and discharge sides of the impeller. This thrust can cause excessive wear and tear on the pump bearings if not properly managed.

Balance Drum Function

The primary function of the balance drum is to balance the axial thrust generated by the pump impeller. It achieves this by creating a hydraulic force that opposes the axial thrust, thus maintaining the stability and efficiency of the pump. The balance drum is typically located at the opposite end of the impeller and is connected to the pump shaft.

Balance Drum and Disc Function

In some centrifugal pumps, a balancing disc is used in conjunction with the balance drum to provide additional axial thrust adjustment. The balancing disc is a flat disc attached to the pump shaft and is designed to counterbalance the axial thrust by creating a hydraulic force in the opposite direction. When combined with the balance drum, the balancing disc ensures precise axial thrust control, leading to smoother pump operation.

Multistage Pump Balance Drum

In multistage centrifugal pumps, the role of the balance drum becomes even more critical. These pumps consist of multiple impellers arranged in series, each generating its own axial thrust. The balance drum in a multistage pump helps to balance the cumulative axial thrust from all the impellers, ensuring that the pump operates efficiently and reliably.

What is a Balance Drum?

A balance drum is a cylindrical chamber filled with fluid, typically connected to the pump shaft. It is designed to counteract the axial thrust generated by the pump impeller by creating a hydraulic force in the opposite direction. The balance drum plays a vital role in maintaining the stability and longevity of the pump by preventing excessive axial thrust on the bearings.

Balance Drum Diagram

The balance drum is a device designed to balance axial thrust generated by impellers; it is usually combined with a thrust bearing which serves to compensate a small amount of residual axial …

2. Calculation of hydraulic and shaft power How to calculate the pump hydraulic power ? The hydraulic pump power calculation is done thanks to the pump flowrate, the pump head and the density of the fluid being pump. Pump power formula is the following : P hydraulic = Q.H.ρ/367. In case the density is changing significantly when the fluid goes through the pump, the density at .
