Pump oem casting impeller design

The Impeller made out of cast material in many cases may be called rotor, also. It is cheaper to cast the radial impeller right in the support it is fitted on, which is put in motion by the gearbox from an electric motor, combustion engine or by steam driven turbine. The rotor usually names both the spindle and the impeller when they are mounted by bolts.

Compression impeller

Working round. The only component of the air flow in a centrifugal compressor. The most important parts on the rotor. Generally by the wheel, wheel cover and blade and other parts of the composition. Under the action of the impeller blades, the rotating speed of the leaf rotation, the gas is affected by the centrifugal force of the rotation, as well as in the impeller of the diffuser flow, so that it can be improved through the pressure of the impeller.

Requirements for impeller

(1) can be given a larger energy; (2) gas flows through the impeller loss should be small, namely the gas flows through the impeller efficiency to be high; (3) gas outflow impeller parameters when appropriate, the gas flowing behind the fixing element flow loss is smaller; (4) type of impeller can make or overall performance curves of the stable operating region and the efficiency range is wide. Normally divided into closed, semi open and open type impeller.

The impeller is composed of a wheel hub and a blade in a wind turbine. The wind passes through the impeller, drives the impeller to rotate, which drives the generator to rotate, and the wind energy is converted into electric energy. At this time, the rotating impeller with large enough on the windward side, to extract enough energy from the wind; at the same time, when the wind speed is too large, can automatically adjust the blade windward angle to avoid due to the stress and mechanical damage.

Impeller material

Cast iron, bronze, stainless steel, manganese bronze, Monel alloy, INCONEL, and non metal materials.

Non metallic materials

PPS plastic, phenolic resin, etc..
