The society has now viewed pumps as very useful devices for the homes, business establishments, and industries. They have a wide range of applications and they are divided into various types such as buoyancy pumps, impulse pumps, positive displacement pumps, velocity pumps, gravity pumps, and steam pumps. Among these many types, the velocity pumps include centrifugal pump, axial flow pumps, radial flow pumps, and mixed flow pumps.
Centrifugal pumps are the simplest equipment among the many types of velocity pumps available in the industrial market. The purpose of using them is to convert the kinetic energy of the fluid being pumped into pressure energy. This energy transformation is made possible because of the action of two main parts, the impeller and the diffuser.
The impeller found in centrifugal pumps is the rotating part that is responsible for converting driver energy into kinetic energy. The diffuser, on the other hand, is the stationary part that converts kinetic energy into highly usable pressure energy.
The two main components of centrifugal pumps are the rotating and the stationary components. The rotating component consists of the impeller and a shaft which are designed to provide the centrifugal acceleration to the fluid. The stationary component is composed of a casing, its cover, and bearings. The impeller is classified further according to mechanical construction: closed type, open type, semi-open type or vortex type.
The first type of impellers found in centrifugal pumps requires wear rings which requires maintenance. The open type and semi-open type impellers are less likely to get clogged but will still require manual adjustment to the diffuser to prevent damaging internal re-circulation. The shaft found in the rotating component of centrifugal pumps transmits the torques which is encountered during the operation.
The stationary components found in centrifugal pumps are made up of two types of casings, the volute and the circular. The job of the volute casing is to help balance the hydraulic pressure on the pump’s shaft. The circular casings, on the other hand, work to provide low head and high capacity.
All the various components that make up the centrifugal pump are very important. Their overall purpose is to achieve high efficiency in whatever purpose is considered at hand.
