Fluid Mechanics Analysis And Calculation Optimization Of The Maximum Allowable Installation Height Of Sanitary Centrifugal Pumps

It is found from the appendix that the saturated vapor pressure of water at 80°C is 47.4kPa. Hv=47.4x103 Pa=4.83mH2O Hs1=5.7+10-10.33-4.83+
0.24=0.78m Substituting the Hs1 value into the formula, we get the installation height Hg=Hs1-Hf0-1=0.78-1.5=-0.72m Hg is a negative value, which means that sanitary pump should be installed below the liquid level, at least 0.72m lower than the liquid level. Single-stage double-suction sanitary pumps is a new type of high-efficiency energy-saving sanitary centrifugal pump. It is nearly 20% higher than the original sanitary centrifugal pumps. 1. Compact structure, beautiful appearance, good stability, easy installation. 2. The optimized design of the double-suction impeller has stable operation, reduces the axial force to a minimum, and has a blade shape with excellent hydraulic performance. After precision casting, the inner surface of the centrifugal sanitary pumps shell and the impeller surface are extremely bright, with significant anti-cavitation performance and high efficiency. 3. The bearings use SKF and NSK bearings to ensure smooth operation, low noise and long service life. 4. The shaft seal is a BURGMANN mechanical seal or packing seal. It can guarantee 8000 hours of leakage-free operation. 5. There is no need to adjust the installation form during assembly, and it can be adjusted according to the on-site use conditions. Independent or horizontal installation.
