Air Compressor Impeller Lost Wax Investment Casting

Product Introduction

Also known as the working wheel. The only component in a centrifugal compressor that does work on the airflow. The most important part of the rotor. It is generally composed of parts such as wheel discs, wheel covers, and blades. Under the action of the impeller blades, the gas rotates at a high speed with the impeller, and the gas is subjected to the centrifugal force of the rotation and the diffusion flow in the impeller so that the pressure after passing through the impeller is increased.

Features of folding

The requirements for the impeller are:

(1) It can give a larger energy head;

(2) The loss of gas flowing through the impeller should be small, that is, the efficiency of gas flowing through the impeller should be high;

(3) When the gas flows out of the impeller, the parameters are appropriate, so that the flow loss when the gas flows through the fixed components behind is small;

(4) The type of impeller can make the range of the stable working condition area and the high-efficiency area of the performance curve of the stage or the whole machine wider. Air compressor impeller lost wax investment casting is often divided into closed, semi-open, and open impellers.

How Folding Works

In a wind turbine, the impeller consists of a hub and blades. The wind passes through the impeller and drives the impeller to rotate, thereby driving the generator to rotate and convert wind energy into electrical energy. At this time, the impeller is required to have a large enough windward surface to extract enough energy from the wind; at the same time, when the wind speed is too high, it is necessary to be able to automatically adjust the windward angle of the blades to avoid damage to the machine due to excessive force.

Folding raw material

Commonly used materials for impellers are: cast iron, bronze, stainless steel, manganese bronze, Monel, INCONEL, and non-metallic materials. Non-metallic materials are divided into: PPS plastic, phenolic resin, and so on.

At present, there is no impeller made of phenolic resin in China. There is a SIMS company in the United States that specializes in making this graphite-based reinforced phenolic resin fiber material SIMSITE, and it has been applied to the impeller of centrifugal pumps. Phenolic resin has excellent alkali resistance and is extremely suitable for pumping seawater.
