Barrier fluid system
Double mechanical seal operation (see shaft seal) requires barrier fluid pressure (see also barrier fluid).
This pressure must always exceed the pump pressure to be seal…
Bellmouth
A bellmouth (also called a suction trumpet, used in conjunction with a centrifugal pump) is a nozzle-shaped inlet casing assembly (see accessories), usually used for vertical tubular…
Bellows
The corrugated pipe consists of a corrugated hose usually made of plastic, rubber or metal (stainless steel). Typical applications include protecting moving parts (such as bellows), compen…
Bearing seat
Bearings are components that allow relative movement and reduce friction between moving machine parts. There is a difference between plain bearings and rolling bearings.…
Belt drive
The belt drive is an optional power transmission device that uses friction to transmit force between the belt and the pulley. The belt used can be a V-belt, a flat belt or a toothed belt fo…
Bilge pump
The name of the pump means that the bilge is the lowest compartment of the ship, and very little water is collected in this area.
The pump is used in underground construction and…
Bernoulli equation
The Bernoulli equation developed by Daniel Bernoulli is an energy balance equation ("energy cannot be lost") in fluid mechanics, and its history can be traced back to the 18th c…
Biogas plant
Biogas plants produce biogas from biomass (for example, semi-liquid fertilizer, plant silage). In the absence of oxygen, the organic matter is fermented at a constant temperature.…
Bimetal
Bimetal, also called thermal bimetal, is an overload protector that activates when subjected to thermomechanical stress. Bimetals include separate strips of different metals that a…
Board part
In the graphical representation of the multiple curved blades in the plane projection, the plate part is a contour line whose contour line is measured perpendicular to the pump shaf…
