Positive effects
Improvement in conveying efficiency
Slurry pumps are capable of efficiently transporting slurries containing solid particles and can be used in the paper industry to transport pulp, sewage, sludge, etc. Taking the common horizontal slurry pump as an example, its double-casing structure and the design of the back blades on the front and rear cover plates of the impeller can reduce leakage, improve the pump's lifespan and efficiency, and ensure stable transportation of slurry during the papermaking process, thereby guaranteeing the continuity and efficiency of production.
Wide range of applicability
The paper-making industry involves the transportation of various fluids with different properties, including concentrated liquids, turbid liquids, fluids containing sediment and slag, and corrosive liquids. Slurry pumps are capable of handling these complex media. For example, submerged slurry pumps can be used to transport various slurries in the paper-making process, meeting the needs of different procedures.
Meet different working conditions
Slurry pumps come in various shaft seal forms, such as auxiliary impeller shaft seals, packed shaft seals, and mechanical seals. In the paper industry, the appropriate shaft seal form can be selected based on different operating conditions. For example, when the positive pressure value at the pump inlet is not greater than 10% of the pressure value at the pump outlet for single-stage pumps or the third stage of multi-stage pumps in series, auxiliary impeller shaft seals can be used, which have the advantages of not diluting the slurry and providing good sealing performance; for operating conditions that are not suitable for auxiliary impeller shaft seals and for pump suction applications, packed shaft seals can be used; for operating conditions that are not suitable for the above two types of shaft seals, mechanical seals are employed to reduce the maintenance frequency of the shaft seal part.
Technological development drives performance improvement
With the continuous advancement of science and technology, the application of new materials, manufacturing processes, and intelligent technologies has significantly improved the performance of heavy-duty slurry pumps. In the paper industry, more efficient and reliable slurry pumps can provide better solutions, enhancing production efficiency and product quality.
Existing problems
The operating environment is deteriorating
The failure of shaft seals may lead to severe leakage, increased vibration, louder noise, and other issues, exacerbating the operating environment of the paper-making workshop and affecting the working environment and physical health of the workers.
Cost increase
Flow passage components are typically made of high-priced wear-resistant materials. In the paper industry, material consumption due to wear will increase production costs. Furthermore, wear reduces the efficiency of pumps, leading to significant energy waste. At the same time, wear will accelerate the replacement frequency of pump flow passage components, increasing maintenance and repair work, thereby increasing labor intensity for workers and maintenance costs for enterprises.
Comprehensive evaluation
Overall, the application of slurry pumps in the paper industry has more advantages than disadvantages. They provide crucial support for slurry transportation in the paper industry, ensuring the normal production process. However, enterprises also need to pay attention to the problems that arise during the operation of slurry pumps. By strengthening technological research and development, reasonably selecting pump types and shaft seal forms, and conducting regular maintenance and upkeep, they can reduce the negative impacts brought by slurry pumps and improve application effectiveness and economic benefits.
