What are the impeller materials of the slurry pump?
First of all, let's look at the structure of the slurry pump: the shell of the slurry pump is composed of the slurry pump pump body and the slurry pump pump cover, the inner shell is composed of the impeller, the jacket, the front and rear guard plate, the inner shell is also called the slurry pump flow parts, the material is generally high chromium alloy and rubber two materials.
Among them, the material of the impeller of the slurry pump is generally Cr26 material, which is also high chromium alloy material, and the general desulfurization and other projects are used more;
Metal material: A07 material, with strong abrasion resistance, can be applied to strong abrasive conditions, the service cycle is relatively long, low cost performance, so the application range is limited.
A49 material has high chromium alloy wear resistance, and has good corrosion resistance, strong acid resistance, especially suitable for a variety of working conditions, such as metallurgy, power plants, coal mines, etc., the use effect is very good, long life,
A05 material price is more civilian, wear resistance is better, the application range is relatively wide;
Rubber material: Corrosion resistance will be better than metal material flow parts, suitable for slurry containing solid particles smooth and no sharp particles.
The shaft seal of the slurry pump is divided into three kinds: packing seal, mechanical seal and auxiliary impeller seal.
The use cycle of the mechanical seal is the longest, the packing seal has some slight leakage, and it is widely used in mineral processing and coal mine, and the auxiliary impeller is more suitable for field use in the relatively scarce water resources.
