balancing drum in multistage centrifugal pump|balance drum and disc function : mail order Dec 8, 2006 · In a high pressure multi-stage pump (such as BFW) the number of impellers is high, thus the net thrust would be large unless something is done to balance it out. The two main … Centrifugal Pump Casing. The centrifugal pump casing seals the pump inside the atmosphere. It is an air-tight boundary that retains the pressure and converts the impeller velocity into a stable flow. In centrifugal pumps, the casing surrounds the pump rotor.The casing converts the velocity head into the pressure head.

In a high pressure multi-stage pump, such as a boiler feed water pump, the number of impellers is high, leading to a significant amount of net thrust that needs to be balanced out for optimal performance. This is where the balance drum plays a crucial role in ensuring the smooth operation of the pump and preventing issues such as excessive vibration and premature wear of components.

Centrifugal Pump Balance Drum: A Key Component for Stability
The balance drum in a centrifugal pump serves as a key component in maintaining the stability and efficiency of the pump system. By effectively balancing the axial thrust generated by the impellers, the balance drum helps to minimize the load on the bearings and prolong the life of the pump.
Balance Drum Diagram: Understanding the Components
A balance drum typically consists of a cylindrical chamber connected to the pump casing through a series of passages. Inside the balance drum, there is a set of discs or pistons that can move axially to counteract the axial thrust generated by the impellers. This movement is controlled by a hydraulic system or mechanical linkage, ensuring that the thrust is balanced out effectively.
Balance Drum Function: Maintaining Hydraulic Balance
The primary function of the balance drum in a pump is to maintain hydraulic balance by offsetting the axial thrust generated by the impellers. This is achieved by creating a counteracting force within the balance drum, which helps to keep the pump running smoothly and efficiently under high pressure conditions.
Balance Drum and Disc Function: Working Together for Optimal Performance
The discs or pistons inside the balance drum play a crucial role in the overall function of the system. When the pump is in operation, these discs move in response to the pressure changes within the pump, adjusting their position to counteract the axial thrust. This dynamic movement ensures that the pump remains balanced and stable, even under varying operating conditions.
In a high pressure multi-stage pump (such as BFW) the number of impellers is high, thus the net thrust would be large unless something is done to balance it out. The two main …
Packing Seals (Gland Packing) An older type of seal, packing gland seals consist of a rope-like material that is packed around the pump shaft. This material is compressed to form a seal, preventing fluid from leaking along the shaft. While less expensive and simpler to maintain than mechanical seals, packing seals have higher friction and can .
