Wear factor
Dredge pump is the heart of dredging equipment, therefore the factors to dredge pumps wear takes an important role to pump use. This topic is going to show the reason and factors of dredge pump wear, in order to provide understanding of dredge pump thory.
Do Pump is a manufacturer of electric submersible sand pump, electric submersible dredge pump, electric submersible slurry pump, hydraulic submersible pump, dredge pump, ladder pump, booster pump, cutter suction dredger and dredging equipment, contact us at info@dopumpgroup.com.
The factors that cause the dredge pump to wear are as follows:
1) Media characteristics.
2) Material properties.
3) Interaction of abrasives with materials.
The main ways to improve the life of pump over-current components are reasonable material selection, reasonable selection, and improved hydraulic design.
The most severely worn part of the dredge pump when pumping the solid-liquid mixture is the impeller, followed by the pump body or overcurrent components such as jackets and guards. Pump wear depends on the intrinsic relationship between the following parameters:
1) Rheological properties of solid-liquid mixtures.
2) Solid particle size, grain shape, hardness and density, and the like.
3) Structure and parameters of the pump.
4) The speed of the pump or the peripheral speed of the impeller.
5) Properties of pump materials such as hardness, strength (elongation, acid and alkali resistance, heat resistance).
Among the factors affecting the life of the dredge pump, the first is the performance of the material, the second is the dielectric characteristics, the third is the structure and hydraulic parameters of the pump, and the operating conditions are at the end.
