In many fields of industrial production, the conveying of slurry is a crucial link. As the core equipment to realize this link, the performance and service life of the slurry pump are directly related to the efficiency and cost of production. Among the components of the slurry pump, some are in direct contact with the slurry. Their quality and state play a decisive role in the overall service life of the slurry pump. These components, during high-speed operation, are subject to the impact of abrasive and corrosive mud for a long time and are very easy to wear, thus attracting much attention.
These components that are in direct contact with the slurry are usually called wet parts, including impellers, bushings, throat sleeves, frame plate bushings, casings, etc. They are like the "front-line soldiers" of the slurry pump, confronting the aggressive slurry head-on at all times. During high-speed operation, the abrasives in the slurry impact the surface of these components with great force, and at the same time, the corrosiveness of the slurry is constantly eroding their materials. Over time, wear of these components is inevitable, and the degree of their wear directly affects the working efficiency and service life of the slurry pump.
For these wet parts to have a long service life, the choice of materials is crucial. Appropriate materials can effectively resist the impact of abrasives and the corrosion of the slurry, thereby extending the service time of the components. In the selection of materials, it is necessary to comprehensively consider the properties of the slurry, such as the hardness, particle size, concentration of abrasives, and the corrosiveness of the slurry. For slurries with strong abrasiveness, materials with high hardness and good wear resistance, such as cemented carbide, are usually selected; for slurries with strong corrosiveness, materials with excellent corrosion resistance, such as stainless steel, are used. Through reasonable material selection, wet parts can stand their ground in harsh working environments and provide a solid guarantee for the stable operation of the slurry pump.
The bearing assembly is another key part of the slurry pump, which is like the "joint" of the slurry pump, supporting the operation of the entire equipment. The bearing assembly of our slurry pump adopts a large-diameter shaft design with a short overhang, which can minimize the deflection of the shaft. The reduction in shaft deflection means that the additional force borne by the bearing during operation will be correspondingly reduced, which helps to extend the service life of the bearing. At the same time, only four through bolts are needed to fix the cylindrical shell in the frame. This simple fixing method is not only convenient for installation but also ensures the connection stability between the shell and the frame, reducing equipment failures caused by connection problems.
As an important part of the slurry pump, the convenience of maintenance of the liner directly affects the downtime and maintenance cost of the equipment. The design of our liner fully considers the needs of maintenance and is fixed on the sleeve by bolts instead of the traditional bonding method. This design makes the replacement of the liner extremely simple. When the liner is worn and needs to be replaced, workers can quickly disassemble and install a new liner, which greatly shortens the maintenance time and improves the utilization rate of the equipment. In addition, the hard metal gasket and pressure-formed elastomer are completely interchangeable. This feature provides users with more choices. Users can choose the suitable type of gasket according to the actual working conditions and cost budget. All liner joints are equipped with elastomer sealing rings, which can effectively prevent the leakage of slurry, ensure the sealing performance of the slurry pump, and avoid resource waste and environmental pollution caused by leakage.
The sleeve is an important load-bearing component of the slurry pump, and its quality is directly related to the overall strength and operational safety of the slurry pump. Our sleeves are made of cast iron or ductile iron. These two materials have high strength and toughness and can withstand the pressure and impact force generated during slurry conveying. At the same time, the outer part of the sleeve is provided with reinforcing ribs, which further enhance the structural strength of the sleeve, enabling it to adapt to higher operating pressures. In the design, we have also incorporated additional safety measures to ensure that the sleeve can maintain stable performance even under extreme working conditions, providing a strong guarantee for the safe operation of the slurry pump.
The impeller is the core component of the slurry pump for slurry conveying, and its design and performance directly affect the efficiency and conveying effect of the slurry pump. The front and rear shrouds of our impellers are equipped with pumping-out blades, which can effectively reduce the recirculation of slurry and seal pollution. The recirculation of slurry will increase energy loss and reduce the efficiency of the pump, while the pumping-out blades can discharge part of the backflow slurry in time, improving the efficiency of slurry conveying. At the same time, reducing seal pollution can extend the service life of the seals and reduce the maintenance cost of the equipment.
In terms of material selection, the hard metal and molded elastomer impellers are completely interchangeable, allowing users to flexibly choose according to different slurry properties and working environments. Moreover, the impeller thread is made by casting without inserts or nuts. This integrated design not only improves the structural strength of the impeller but also reduces the number of parts, lowering the assembly difficulty and the hidden danger of faults. In addition, we also provide high-efficiency and high-head designed impellers, which can meet the needs of different users for slurry conveying distance and height, providing more personalized solutions for users.
The throat sleeve plays a role in connection and guidance in the slurry pump, and its design has an important impact on the wear and maintenance of the equipment. Our throat sleeve uses a conical mating surface, which effectively reduces wear. The conical mating surface makes the contact between the throat sleeve and other components more uniform. During operation, the wear can be evenly distributed, avoiding local excessive wear, thereby extending the service life of the throat sleeve. At the same time, the design of the conical mating surface also simplifies the maintenance work. During assembly and disassembly, accurate centering can be achieved, reducing component wear and equipment failures caused by inaccurate centering, and improving the efficiency and quality of maintenance.
Due to the harsh working environment of the slurry pump, parts such as impellers, volute liners, bushings, and throat sleeves will inevitably wear out after long-term use and become consumables. To ensure the smooth progress of users' production, we have established a sound parts supply system, which can provide users with qualified parts in a short time. We have a professional production team and advanced production equipment to ensure that every part leaving the factory meets quality standards.
