What are the advantages and disadvantages of single-stage centrifugal pump?

Single-stage centrifugal pump is the most advanced hydraulic model, its performance parameter design in strict accordance with the international iso2858 design, which basically guarantees the efficient energy-saving products, installation, maintenance, smooth operation, Safe and secure, but at work it also reveals not a performance weakness. Next, the advantages and disadvantages of single-stage centrifugal pump which are analyzed. What are the advantages and disadvantages of single-stage centrifugal pump? Single-stage centrifugal pump advantages: (1) energy-efficient: CFD CFD, analysis and calculation of the pressure distribution within the pump and the relationship between the velocity distribution, to optimize the design of the pump flow to ensure that the pump has efficient hydraulic shape line, improve the pump s efficiency. (2) Easy installation and maintenance: vertical pipeline structure, the import and export of the pump can be installed in any position and direction of the pipeline like a valve, and the installation and maintenance are very convenient. (3) Smooth operation, safe and reliable: The motor shaft and pump shaft are coaxial and coaxial, with high concentricity, stable operation and safe and reliable operation. Single-stage centrifugal pump Disadvantages: (1) single-stage centrifugal pump needs to be started before pumping or pump equipment to pump the air out. (2) liquid viscosity of the pump performance is relatively large. (3) Single-stage centrifugal pumps are susceptible to impact when used in low flow environments. For single-stage centrifugal pump users, they are more concerned about the advantages and disadvantages of single-stage centrifugal pumps when choosing products because the advantages and disadvantages of single-stage centrifugal pumps are the basis for the work of single-stage centrifugal pumps Conditions, single-stage centrifugal pump if the inability to ensure that the advantages of single-stage centrifugal pump to meet the needs of work, while the single-stage centrifugal pump does not affect the shortcomings of the use of single-stage centrifugal pump, then the use of single-stage centrifugal pump less important.
