1??What are the essential structural element of centrifugal pump????A centrifugal pump as a technical system consists of the following major structural sub- systems: the impeller blades, the discs of the impeller, the body, the discharge nozzle, and the suction nozzle." See Attached Pic"2??How was centrifugal pump classified ????" See Attached Pic".3??What is volute type of centrifugal pump????A pump named from it's spiral - volute from of casing which acts as a collector for the fluid discharged by the impeller. Wall T, divided the beginning of the volute and the discharge nozzle, is called the "volute tongue" Or "cut water""For Calrify See Attached Pic"4??What is diffuser type of centrifugal pump????In this pump diffuser vanes converts the velocity energy imparted to the liquid by the impeller to the pressure energy. The diffuser vanes assembly is known as the "diffuser"."For Calrify See Attached Pic"5??What is multistage pump????It is total head required too high for single impeller to produce, two or more impellers may be used in series, the second impeller taking it's suction from the discharge of the 1st impeller.If all impellers acting in series are in a single casing, the pump is a multi design.6??What is double suction impeller????It is in effect two single suction impellers cast back to back so that liquid enters the impeller simultaneously from both sides. .7??What is francis Vane impeller????Its vane surface have a double curvature, and it is called "Francis screw vane" or "screw vane" impeller.8??What is an ovarhung impeller????If the impeller is supported by bearing on one side only and shaft does not extend beyond the suction side of the impeller hub it is called overhung impeller. The design makes possible the end suction pump.9??What is suction eye of an impeller????The inlet just before the point where the vanes start it is called the "suction eye". In a closed impeller pump the diameter of the suction eye is the taken As the smallest diameter of the shroud.1??0??What is casing wear ring????Sometime called an "impeller guide ring". It is inserted in a pump casing to protect the latter from wear.1??1??What is impeller wear ring????To protect the impeller from wear at its running joint within a casing or casing ring, it is fitted with a removable ring called an "impeller wear ring".1??2??What is dynamic balance????A pump rotor is dynamic balance if all the various centrifugal forces resulting from it's rotation balance each other. Such rotor runs at full speed without vibration.1??3??What is a Pump BOWL????In vertical turbine pump and propeller pump practice, the bowl is the stationary part containing the diffusion vanes.
