As a Slurry Pump Impeller Supplier, share with you. The factory usually must process the slurry from treatment to wastewater treatment. Handling this mixture of liquid and solid is challenging and difficult. Some of the key factors in pumping mud are the size and nature of the solids in the liquid and the type of abrasive wear they cause. The other is the corrosiveness of liquids or mixtures.
The site often relies on centrifugal pumps to provide mud services. These pumps require special regulations, requiring detailed knowledge of the properties of solids and slurries to prevent wear, corrosion, corrosion and other adverse effects such as solids settling. Specifying the optimal combination of speed, geometry, and material requires proper balance of often conflicting pump priorities; this requires consideration of stable operation, maximum wear life, operational flexibility, and minimum energy consumption.
Horizontal centrifugal pumps are commonly used for mud service, although vertical pumps and other types of pumps are favored in some specific applications. The centrifugal pump used to process mud has a function tailored to specific purposes, which can reflect the corrosiveness or abrasiveness of the mud and the solid concentration. These may include the choice of materials, the use of linings, and even different drive sizes.
The first main requirement of Slurry Pump is to provide sufficient service life. The corrosion and corrosion effects of the slurry are indeed challenging. In many applications, some solids in the mixture are larger than normally specified particles. Therefore, the pump should be able to pass through them without causing any damage or operational problems.
The performance curve of many centrifugal pumps is based on the amount of water processed. Therefore, to obtain the performance characteristics of these slurry centrifugal pumps, the results must be modified to ensure the presence of solids. There are many correlations and correction methods to predict the performance of centrifugal pumps when handling mud. These take into account factors such as the individual influence of particle size, particle size distribution, specific gravity and solids concentration.
The main factors affecting wear include:
• Details of corrosive particles;
• Fluid velocity and particle velocity;
• The fluid dynamics of the flow.
Turbulence analysis is usually not suitable for Slurry Pumps, because the presence of solid matter will directly affect the turbulence parameters. The mechanism of turbulence becomes a complex problem, especially for dense slurries. This is combined with the nature of the flow inside the mud pump, which is characterized by instability and deformation of the velocity distribution pattern, resulting in a very chaotic situation. However, some simple rules have been verified theoretically and experimentally. For example, the corrosion wear rate is proportional to the flow rate. It also depends on the solids concentration. As the concentration increases, the wear rate also increases. In addition, the sizing and specific gravity of the solids in the slurry will affect wear.
