Yongjia Liangbang pipeline pump selection is based on the internationally recognized ISO2858 standard and incorporates the latest hydraulic models. The design also takes into account relevant international standards, offering an alternative to the SG pipeline pump. This approach ensures high performance, reliability, and compatibility with global industry practices.
The selection process of a pipeline pump should be based on five key factors: fluid flow, system head, liquid properties, pipeline layout, and operating conditions. These aspects are crucial for ensuring the pump operates efficiently and meets the specific needs of the application.
1. **Flow Rate**: One of the most important parameters in pump selection, flow rate directly affects the production capacity and efficiency of the entire system. In engineering design, it's common to calculate normal, minimum, and maximum flow rates. When selecting the pump, the maximum flow rate is typically used as the basis, unless it’s unavailable, in which case the normal flow rate can be considered as the maximum.
2. **Head Requirement**: The head required by the system is another critical parameter. It's usually recommended to select a pump that provides 5% to 10% more head than the calculated requirement to ensure reliable operation under varying conditions.
3. **Liquid Properties**: Understanding the characteristics of the liquid being pumped is essential. This includes temperature, density, viscosity, presence of solid particles, gas content, and chemical composition. These properties influence the type of pump, materials used, and the sealing method required.
4. **Pipeline Layout**: The configuration of the piping system, including suction and discharge heights, distances, pipe sizes, fittings, and material specifications, plays a significant role in determining the pump's performance and efficiency. It also affects the Net Positive Suction Head (NPSH) calculation.
5. **Operating Conditions**: Factors such as ambient temperature, pressure, continuous or intermittent operation, and pump location (fixed or mobile) must be considered during the selection process.
The single-stage pipeline pump is ideal for various applications, including industrial and municipal water supply, fire boosting systems, long-distance water delivery, and heating/cooling cycles. It offers stable operation, low noise levels, and a wide range of applications, making it a preferred choice for many industries.
The FG-type pipeline pump follows the ISO2858 standard and uses advanced hydraulic designs. It is developed as a replacement for the SG-type pump while maintaining similar performance and technical specifications. This ensures compatibility with existing systems and enhances overall efficiency.
The DFRG centrifugal pump also adheres to the ISO2858 standard, featuring the latest hydraulic models and designed as an alternative to the SG pipeline pump. Its performance parameters match those of the IS-type centrifugal pump, meeting all necessary design requirements.
