Barge used sand dredge pump is designed for continuously handing the most difficult higher abrasive slurries which contain too big solids. The big particle gravel sand pump is casted as a single pump casing structure with smooth over-current channel .The overflow part is made of hard nickel and high chromium wear resistant alloy. The outlet direction of gravel pump can be adjusted according to the request direction. The gravel sand pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging and so on. The advantages of the barge used sand dredge pump are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.
When it comes to slurry transport, familiarity with the pump and its components is par for the course. However, it is also important to understand every element of slurry transport. This understanding starts with a few basic questions.” What is the difference between a Dredge Pump and a water pump?” “What makes a barge used sand dredge pump different?” and “What types of dredge pump installations are there?”
1. What is the difference between a barge used sand dredge pump and a water pump?
Slurry is distinguished from other fluid types by the presence of solids – gravel, copper or sand – in the fluid. Although in many cases the fluid is water, slurry may contain solvents, such as acids, alcohols or petroleum. These non-aqueous components, whether solids or solvents, make dredge pump necessary.
In contrast to the narrow and often inexpensive components of pumps, large replaceable dredge pump components are made of strong, often specialized materials. These parts allow the pump to efficiently and safely move almost any type of solids in the slurry. Pumps, on the other hand, lack the hydraulic capacity to move solids and cannot withstand the particle wear and chemical corrosion that slurry can cause.
2. What makes a barge used sand dredge pump different?
A dredge pump can withstand a lot of wear and tear due to the following features: large impeller diameter, shaft, bearings and internal passages, and heavy-duty construction. On an industrial level, the characteristics of dredge pumps generate higher upfront and operating costs compared to water pumps. However, only dredge pumps are effective in hydraulically transporting solid materials, and their long-term benefits outweigh the initial costs.
The key to the success of the barge used sand dredge pumps is the generation of centrifugal forces that push the material outward from the center of the pump. This is in contrast to centripetal force, which pushes the material toward the center. Dredge pumps must operate according to the centrifugal principle because the forces that give the slurry its velocity accelerate the transport process. On the other hand, a centripetal pump is impractical because solids in the slurry will accumulate rather than flow freely.
3. What’s the structure of the barge used sand dredge pump?
It adopt international advanced technology, non-clogging design with big flow channel and 3-Vane high efficiency closed impeller. Large solid particles are allowed.
- Bearing assembly – a large diameter shaft with short overhang minimizes deflection & contributes to long bearing life.
- Casing – single casing be made of high-chrome alloy, provide long wear time.
- Impeller – 3 vanes impeller, processing larger solids easily. The impeller and casingof the barge used sand dredge pumpare threaded connection,no need nuts. High efficiency and high head designs are also available.
- Cover plate – wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
- One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided for easy adjustment of impeller clearance.
4. How to install the barge used sand dredge pumps?
Knowing these basics, it is also important for anyone who wants to install a dredge pump to understand the specific environment required for each type of pump. Three types of slurry installations exist.
Wet – In this type of installation, the dredge pump and drive unit are completely submerged in water. This is necessary for certain barge used sand dredge pump applications, such as underwater operations.
Dry – In this installation, the pump drive and bearings are not in the slurry. The wet end – which includes the housing, impeller, hub or suction liner, and sleeve or stuffing box – is independent of any surrounding liquid. Dredge pump technicians install most horizontal pumps in this manner.
Semi-dry – This special arrangement is used for horizontal pumps in dredging applications. The operator submerges the wet end and bearings, but keeps the drive unit dry. In this case, the bearings require special sealing arrangements.
Although this guide provides an overview of barge used sand dredge pumps and their installation, there is much more to learn. For those who want to better understand dredge pumps and their applications or need help deciding which pump and installation type is best for their application, we are here to help.
