Backflow
Preventing backflow of the fluid delivered to the centrifugal pump is essential to avoid hazards.
Not allowed reverse speed
Mechanical damage occurs when starting the pump in reve…
Pull-out back design
Pull-out back design refers to the type of centrifugal pump design, which meets the requirements of the refinery for quick disassembly and reassembly, so it is often used…
Backstop
The function of the backstop is to prevent the pump from rotating in the reverse direction. The working principle of the backstop is the same as that of the free wheel. Once the direction…
Back-to-back impeller pump
Back-to-back impeller pumps have multiple impellers mounted back to back on a common pump shaft. This is an effective way to balance the axial thrust that occurs duri…
The balance drum is a device used to balance the axial thrust generated by the impeller. It is usually used in combination with a thrust bearing to compensate for a small amount of residual axial th…
Balancing is the process of correcting the uneven distribution of geometric mass (see Unbalance). In the case of a centrifugal pump, perform this operation in such a way that the rotation axis of th…
Balance device
The balance device on the centrifugal pump is designed to fully or partially compensate the axial thrust generated by the pump rotor. Designs containing a single balance drum or…
Barrel pump
The barrel extraction pump is a centrifugal pump surrounded by a barrel-like shell. As far as feedwater pumps for power station applications are concerned, they are also called barrel pump…
Base-plate
During the installation of the centrifugal pump, the bottom plate is used as the connection base for the pump and the related drive (pump foundation).
These two components are…
Barrier liquid
The protective fluid (see Barrier Fluid System) required to operate the dual mechanical seal (see Shaft Seal) is usually hydraulic oil or water.
